NASA's Chief Backs Plan Privatizing Astronaut Travel

NASA's administrator is defending the president's proposed budget for NASA, which cancels the space agency's planned space shuttle successor and instead relies on private companies to taxi crews into orbit. Charles Bolden said executives from seven companies working on commercial crew vehicles are "the faces of a new frontier."

Storms In Space Disrupt Travel On Earth

Airlines are checking the weather in space these days before taking some of their longest flights. That's because thousands of flights each year now cross the poles, where cosmic storms can interfere with communication and navigation systems, or even expose travelers to worrisome doses of radiation.

 

Congratulations, Rebecca Karger, winner of the NXT set!

nxtbig.jpg

The gods of Random.org have crowned Rebecca Karger, a student at Horace Greeley High School, winner of our Lego Mindstorms NXT 2.0 set. This is what Rebecca had to say about what she'd do with the set:

If I had this kit, I'd take it with me to college next year, and build a robot that could go down the hall of my dorm to deliver a note to a friend. And probably 500 different other things. I was on an FLL team in middle school that went to the international competition, but it was the year BEFORE the NXT kits came out! I remember seeing a demo and being highly impressed, but my parents say the kits are too expensive.

Rebecca: so yeah, your FB settings are kinda restrictive. You're going to have to get in touch with me if you want the prize. I'm at facebook.com/nerd1.

Lost Knowledge: Magic lanterns

The Lost Knowledge column explores the possible technology of the future in the forgotten ideas of the past (and those just slightly off to the side). Every other Wednesday, we look at retro-tech, "lost" technology, and the make-do, improvised "street tech" of village artisans and tradespeople from around the globe. "Lost Knowledge" was also the theme of MAKE Volume 17


Ever since we humans started making shadow puppets in the firelight of our caves, we've been fascinated by the power of the projected image. It seems only fitting that, for DIY Movie Making Month, we'd take a look at magic lanterns, some of our first technological baby steps that have delivered us to the age of Avatar.

What is a magic lantern? It's basically a 17th century pre-cursor to the slide, and then movie, projector. The Magic Lantern Society defines a magic lantern as:

...an appliance by means of which transparencies are projected by artificial light upon a screen with the projected image having a diameter generally from thirty to eighty times greater than that of the transparency or slide, whilst the area of the image may be from one thousand to six thousand times as great.

Magic lanterns grew on the developments of magic shadow shows (i.e. shadow puppets), camera obscura, magic mirrors, and other earlier optics and projection techniques. The period of the magic lantern spanned from the mid-17th century to the late 19th. While there is no clear inventor of the device, Dutch astronomer, mathematician, and physicist, Christiaan Huygens (1629-1695), with his lenses designed for use in telescopes, is probably the closest thing to a father of the technology.

How-To: Make a multiband EFHWA for amateur ham radio

EFHWmain.jpg

For portable radio operation, I like End-Fed Half-Wavelength Antennas (EFHWA, pronounced "EF-WAH"). This type of antenna is similar to the common half-wavelength dipole, but with one significant advantage. A dipole has its feedpoint (where it connects to the radio) in the middle of the antenna, but an EFHWA's feedpoint is at one end. This makes it very convenient to throw the antenna up in a tree and connect the bottom of it to your radio. Here are instructions for making a multiband end-fed half-wavelength antenna that works on 17, 20, 30, and 40-meter bands.

This tablecloth wants you to spill things on it

underfull_tablecloth.jpg

Here's a neat idea for a tablecloth, by Kristine Bjaadal. Normally, one would avoid spilling things on their linens, however the Underfull Tablecloth has a hidden pattern built in that only shows up once it becomes stained. Now you can look at that lovely butterfly pattern and remember that one time you had a bit too much wine, without feeling bad about having ruined the tablecloth! [via neatorama]

In the Makers Market: Wire trees


Makers Market seller Kevin of kaitrees has a bunch of great videos on his market blog. They range from details of the pieces themselves, to "slap tests", and works in progress. It's a neat look at the process that goes into making these pieces.

My sculptures are an effort to distill what real trees inspire in people into something one can have inside their living or working space.



This tree in the video above will require about 500 hours to complete, stand over 7 feet tall, and will use about 1000 strands of aluminum wire. It's his largest piece to date, and looks Amazing! I wonder how much it will weigh?

Letters From the Fab Academy, Part 4

3D Scanning

By Shawn Wallace


FabAcademy04img01.jpg

Victor Freundt prints a project using the ZCorp printer at the Barcelona Fab Lab.


When working with 3D scanning and printing equipment, it quickly becomes apparent that objects are nowhere near as fungible as MP3s. We'll have to wait a while for the day when every teenager is capable of casually copying real-world objects. However, it is surprisingly easy to hack together a crude 3D scanner from commodity cameras, projectors, and hardware you probably have in a couple of junk drawers in your shop.

A good place to start is with the Modela mini mill, which has a piezo-based needle sensor attachment that can be used for scanning small objects. The machine records the plunge depth at the point it contacts the object and the software that comes with the Modela (Dr. Picza) converts these points into a 3D mesh. Here's an example of using Dr. Picza to scan a small shell from Benito Juarez from the Barcelona Fab Academy site:

Arduino-controlled ball-and-bowl musical instrument

kugli1.jpg

kugli2.jpg

kugli3.jpg

Kügli is an Arduino-controlled musical instrument by Stefanie Hess and Johannes Schmidt. The project consists of a bowl with a false bottom, packing an Arduino, XBee wireless module, and some speakers. The ball contains a Lilypad and another XBee.

The spacing and dynamic of a ball in a bowl influences sound. While holding the bowl in its hands the player can walk around and rock the bowl forth and back either smoothly or with fast movements. Two factors are relevant for the sound: the position of the Kügli in the ball and the rotation-speed of the Kügli. Both data streams are sent to Max/Msp via the serial port. The XBee component, accelerator and piezo-microphones are sensoring and passing the the movements.

Wireless Robotics Platform: R/C Vehicle + Arduino + XBee + Processing


An anonymous MAKE subscriber writes in to let us know about this very cool wireless robotics platform based on the Arduino and an XBee. The purpose of the project was to teach their 9-year old son about programming in Processing. What a great way to introduce programming to kids!

I built a wireless robotics platform from a cheap R/C car, an Arduino with XBee shield, small microswitch sensors, and a Processing program running on a remote computer to control the vehicle. The vehicle is completely controlled by the code running on the remote computer which allows very rapid prototyping of the code to tell the vehicle what to do and how to react to the sensor events received from the vehicle. I'm hoping this is a good way to teach my 9-year old son about programming.

Intern's Corner: How to photograph your DIY project

MAKE: Intern's Corner
Every other week, MAKE's awesome interns tell about the projects they're building in the Make: Labs, the trouble they've gotten into, and what they'll make next.

Part 1. Setting up a background for your project.

By Ed Troxell, photo intern

As a DIYer, you share your projects to show off your expertise and to help others find theirs. But building a project and writing the steps is only half the battle. The other half is capturing images of your work that clearly show what you're talking about and what you've done in your steps.

As the photo intern for MAKE, I shoot lots of projects for the magazine and website. Here are my steps for setting up a background for photographing your project clearly to show it off in its entirety.

1. Set up your project and mini studio.
Find a well-lit area that's clear of visual distractions and provides you with enough room for shooting. If you're shooting on a workbench, clear off all the clutter and if necessary, drop a bedsheet or paper backdrop to hide everything that's not your project. The camera doesn't want to see your mess, it just wants to see your masterpiece. Extraneous items on the bench or in the background will only confuse the viewer and make a good project look bad. Clean up before you shoot.

Clean bench good (but what's that junk in the corner?):
IMG_3610lores.jpg

Cluttered bench bad:
IMG_3612lores.jpg

2. Know your "light temperature."
Light temperature means the color of your light, and it affects your "white balance." Most cameras react best to daylight, which is a bluish light, and I strongly recommend shooting in daylight. Shooting your project near a big window (with no direct sunbeams coming through) is a good place to start. Shooting outside in smooth shade is good option too (but not in speckled tree shadows).

Your flash is daylight balanced, so you can use your flash as a "fill" or secondary light to fill shadows. (Your flash should never be the main source of light, unless you're using a real strobe system.) Also, most of those compact fluorescent light bulbs are close to daylight balanced. They can be a nice fill too.

Just be careful not to mix the color of your lights. The white balance on your camera will get confused if warmer light is in the room (like a normal household tungsten filament light bulb), conflicting with the daylight or CF lights. Choose the light temperature you're shooting with, and stick to it.

3. Choose a clean background.
Use a plain, simple background, nothing too distracting. You want clean backgrounds that show off your work. Pick colors that go with your project or make it stand out. We tend to use bright colors. We recommend not using red, as red is a very difficult color for digital cameras. Do not use black. White is fine.

Instead of a distracting background pattern like this:
IMG_3618lores.jpg

Use a clean background color like these:
IMG_3617lores.jpg

4. Place your project on a level and straight surface.
Here's the photo booth we use here in the Make: Labs for shooting indoor shots, when we're not shooting on the workbench:
IMG_3604lores.jpg

5. Test your settings.
Take a few shots, then check the images on your computer (ideally in Photoshop) just to check focus, brightness, file size, grain (ISO), and other details. Sometimes a setting can be off. It's best to know now, rather than find out when you're done shooting.

For example, if you're submitting projects for MAKE magazine or Make: Online, you'll need to take high-resolution photos at an aspect ratio of 4:3. High resolution means they can be printed on paper at 300dpi. (Yes, even web photos -- because we might want to print them later.)

In my next post: Shooting your project in high resolution.

Biking directions added to Google Maps

Pt 2669
Biking directions added to Google Maps... here's my route from Adafruit to NYC Resistor!

Whenever I meet someone who finds out that I work on the directions team for Google Maps, the first question I'm asked is often "So when's Google Maps going to add biking directions?" We're big biking fans too, so we've been itching to give you a concrete answer. I don't want to keep the good news a secret any longer, so the answer is: right now!


Excellent way to get around, now even easier.

Old T-shirt makes great MAKE cozy

andymakesleeveopen.JPG

Andy Johnson writes in:

I'm a guy that sews. No, I'm not afraid to say it, I think it is one of the best skills my Mother taught me, besides cooking. I sewed this magazine protector to keep my latest copy of MAKE looking newsstand fresh. I carry MAKE in my backpack, and I carry my backpack everywhere. With all the junk I carry banging around in there, it can get my stuff pretty hammered. I took my favorite T-Shirt, that unfortunately has worn out, and cut out a rectangle 1/2 inch larger than my copy of MAKE on both sides, and doubling the length so it can be folded over. I created a flap on the top and sewed velcro to both the flap and the reverse of the protector. Surging the seams would be the best, but I only have access to a regular sewing machine. If you have extra t-shirt, you can use it to make ipod sleeves, calculator protectors, whatever you like.

It's upcycling month at CRAFT, so head on over for some more great recycling projects with our UpCraft! series.

Hey television pixelbots, water my plant

Julia Tsao's Curious Displays thesis project proposes swarms of half-inch pixelbots, which could form into a TV or perform other robotic tasks.

Each block operates independently as a self-contained unit, and has full mobility, allowing movement across any physical surface. The blocks operate independently of one another, but are aware of the position and role relative to the rest of the system. With this awareness, the blocks are able to coordinate with the other blocks to reconfigure their positioning to form larger display surfaces and forms depending on purpose and function. In this way, the blocks become a physical embodiment of digital media, and act as a vehicle for the physical manifestation of what typically exists only in the virtual space of the screen.

Julia even provides a prototype remote control, made improbably gigantic by such buttons as NEEDY, MELANCHOLY and ZEN which would activate pre-pogrammed pixelbot behaviors. Part of the project even includes simulated instructions for dealing with rogue pixels that are hiding under the couch! [via Fast Company]

Motoruino, an Arduino-compatible robot board

motoruino_board.jpg

Guilherme Martins wanted a simple Arduino-compatible board that he could use as a robotics platform, so he designed one. Called the Motoruino, he took a standard Arduino board and added an H-Bridge chip so that it can control two motors directly. Of course, you could certainly get the same functionality using an add-on board such as the MotorShield (or even by making your own on a breadboard). If you know you are going to be making a robot, though, I can certainly see that having everything together on a single piece would help make your project smaller and more reliable.

He is working on some final tweaks, and plans to release the project under the Creative Commons license. Cool stuff! [via Lets Make Robots]

How-To: Make great big stuff

giant_match_ignition_better.jpg

giant_sandwich.jpg

I've had this long-standing concept for a theme restaurant where everything--tables, chairs, utensils, food, condiment dispensers--is like 30% bigger than normal. The idea is to make you feel like a kid again. We'd call it "Tiny's." (And yes, we're still seeking investors. Also waitstaff suffering from gigantism.) Look for one soon in a strip-mall near you. Believe me, you won't be able to miss it.

In the meantime, if you just can't wait for the experience, you could always start filling up your house with great big versions of the stuff you already have. Instructables has just posted a cool round-up of tutorials on how to do just that. Shown uppermost is user Tetranitrate's giant match. And yes, as the middle photo shows, it does (or did) actually work. At bottom, last but in no sense least, there's user indymogul's giant sandwich, which I think was part of a Halloween costume or something. But who cares? Giant sandwich!

  • Claes Oldenburg is a famous Swedish sculptor, associated with the Pop Art movement, who made great big versions of stuff as sculpture.
  • GreatBigStuff.com is an online store that only sells...well, you can guess, can't you?

Neat demonstration of proportional and PID control systems

Spotted in the MAKE Forums:

Liam built this impressive robot, then used it to demonstrate the difference between proportional and PID control. The robot is designed to stay a certain distance from an object, and uses two Sharp IR distance sensors to track it's position. The system looks like it is working great, however he is noticing some variability in the output of the distance sensors he is using- anyone have any ideas?

This is the GBOT with a PID controller using the ZX-40A microcontroller from http://www.zbasic.net. ZX-40A is based on the ATMEGA644 AVR chip. Inputs include 2 IR range sensors (GP2D12). Outputs include 2 PWM signals to the Pololu motor driver (VNH2SP30).

The GBOT maintains a setpoint distance of 10-inches from a target and maintains that distance, no matter what. The control system was originally coded with P-control only and resulted in excessive overshoot and oscillations. So then I added PID control. See video to observe P-control vs. PID control.

Had trouble with IR sensor noise. Issue mitigated with hardware and software. Hardware... added low ESR 1,000uF capacitors on VIN and VOUT of the LM2940T voltage regulator. Software includes an 8th order butterworth filter to clean IR sensor position and velocity. I did have issues with a fire, probably caused by a short or the motor driver. Not sure yet. Since isolating the regulator with the filters and after adding a large heatsink to the voltage regulator, no more fires. See picture below of "incident".

Anyone have experience or information on GP2D12 IR sensor distance variability? I have the noise reduced to 0.025" amplitude. Can this be reduced further? Thanks.

STS-131 mission brings robotics outreach to teachers, students

MAKE_NASA_RoboticsSite.jpg

The upcoming mission of the space shuttle will focus heavily on robotics and NASA is using that opportunity to bring additional educational outreach to teachers and students. In an education briefing today, NASA detailed some of the resources and events related to STS-131. The robotics section of the NASA web site includes lesson plans, multimedia, information about robotics competitions, and career profiles of ways students can use math, science and engineering in various robotics jobs. STS-131 Mission Specialist, Dorothy Metcalf-Lindenburger, is a teacher-turned-astronaut and will be recording an educational video about the space shuttle and space station robotics operations while on-orbit and crew members will participate in two live educational downlinked events during the mission. You can follow the STS-131 mission on the NASA web site and check the NASA TV schedule for all televised mission events.

Energizer battery charger contains backdoor? REALLY?

Energizer Duo
WHAT? Un-freaking-believable! Energizer battery charger contains backdoor

The United States Computer Emergency Response Team (US-CERT) has warned that the software included in the Energizer DUO USB battery charger contains a backdoor that allows unauthorized remote system access. In an advisory, the US-CERT warned that he installer for the Energizer DUO software places the file UsbCharger.dll in the application’s directory and Arucer.dll in the Windows system32 directory. An attacker is able to remotely control a system, including the ability to list directories, send and receive files, and execute programs. The backdoor operates with the privileges of the logged-on user.

When considering a battery charger, if there's an open source one, choose it - and avoid the one that comes with software for no good reason, otherwise this could happen... MAKE stocks the MintyBoost, and while that charges devices (not batteries) - it's open source, does not require software, will not trojan your computer.

The city at night is made of light

tokyo_glow_screencap.jpg

Tokyo/Glow is an absolutely gorgeous short film, written and directed by Jonathan Bensimon, about the little glowing guy from a cross-walk sign who jumps down from the sign, at night, and wanders around Tokyo gawking at all the lights. I don't think there are any CG effects. The film's amazing look was achieved by combining a real actor in a custom glow-suit with a bunch of photographic hi-jinks: stop-motion, time-lapse, long exposure...did I miss anything?

Super Mario Brothers with an Arduino


Although this is still a work in progress, I think it's great! All you need is an Arudino, a few buttons, and an 8x8 LED matrix to make you own simplified version of this arcade classic. What's next Halo? Let's hope so! More information, including the Arduino code, can be found in the Vimeo description.

This is a game project for S10-05833 - Gadgets, Sensors, and Activity Recognition in HCI taught by Scott Hudson at Carnegie Mellon University. I created a simple version of Super Mario Bros using an 8x8 LED matrix (one color), an Arduino Nano, two buttons for the input (forward and jump), and a piezo sensor hooked to a separate Arduino for the theme song.

Android-powered Garduino remote control

Garduino Remote

Dan Morrill decided to take the Garduino system that he built a step further, and created a remote control that runs on an Android phone and talks to the Arduino over Bluetooth:

In practice, it takes your "Serial.print" output from an Arduino program and makes it available over Bluetooth to a PC..... or a phone. Android, meanwhile, added an API for Bluetooth RFCOMM in version 2.0. My wife got me a BlueSMiRF for my birthday, and it was off to the races.


I rewrote the Arduino code into a simple finite state machine, and added the ability to accept commands over serial. It's a very simple project, so there are only 2 commands: reset, and set current time. I encountered some interesting open-source related issues in doing this, but that's another post.

I then wrote a spiffy little Android app that pairs up to the BlueSMiRF, reads the state dumped from the Arduino every 3 seconds, and then makes a pretty little Android UI. It shows me a Sun, Moon, or Clock depending on which state the Arduino is in (daytime, nighttime, or waiting for clock data), and reports the other status fields like light intensity and status.

Dirt-cheap robotics prototyping environment with Android

cellbot.jpg

Tim Heath and Ryan Hickman's Truckbot could be built for under $20 (excluding mobile). That's pretty impressive for such an open and accessible robotics prototyping environment. Using a laser-cut cardboard chassis, $3 micro servos, and a bare bones Arduino, the duo have assembled one of the cheapest platforms to come along in a while. [via GadgetLab]


One of the main reasons for using cell phones as part of robots is to drive down costs. Today's phones come with wi-fi, cellular connections, Bluetooth, GPS, touch sensing, accelerometers, magnetometers, displays, microphones, speakers, and cameras. They are now being powered by 1Ghz processors and come with ample amounts of storage. Everything you need in a robot except for mobility is already in your pocket. We just needed to add some inexpensive mobility to it.

Basics: Finding pin 1

pin numbers - 03

You've got your components, and your datasheet, and you're read to start hacking. But which way does the chip go? Pin 23 is where? If you're lucky, the orientation is clearly marked, or perhaps diagrammed in the datasheet. But if it isn't, or if you're simply new at this, it's helpful to know what to look for.

In the picture above, pin 1 is clearly marked on the Allen-Bradley resistor pack. And for better or worse, this is the exception, not the rule.


numbering


Here is a basic rule that applies for most integrated circuits: There's a polarity mark somewhere. From that polarity mark, move counterclockwise around the chip, and number the pins starting at 1.

A common polarity marker is a half-moon shape at one end of the chip. Another is a small dot by pin 1, or sometimes a small triangle or tab instead. Sometimes several of these marks can appear.

Often pin 1 is in a corner of the chip, and it's only that corner-- not the pin itself --that is marked by the small circle or triangle.


In this sketch, we've drawn an imaginary part number "THX1138D," manufactured in week 37 of 2013, and it has a mysterious lot or internal code "OHAI" that may or may not be explained in the datasheet. The polarity marks are a half-moon indentation on the left hand side as well as a dot by pin 1. This device has 20 pins, numbered counterclockwise along the two edges from 1 to 20.


As we'll see, there are plenty of examples of this, or close variations on it. But there are also cases where there are *no* direct marks, but you can instead rely on the orientation of the text to understand the numbering. The text orientation is consistent, and for chips of this shape (with pins on two opposite sides), you can reliably assume that the polarity mark goes to the left of the text.


pin numbers - 02

Here are some classic and beautiful examples of chips with well-marked polarity. These are "ceramic DIP" integrated circuit packages, dated from the end of 1978. Each has a molded half-moon shape as well as a more subtle dot by pin 1.


pin numbers - 27

This is a modern higher-density variation on the same design. It's a wide, low-profile plastic package called a 66-pin TSSOP (and a 128M bit DDR SDRAM, if you're curious). The orientation is given by the half-moon shape on the left hand side and by the dot in the lower left corner. Now, that dot actually looks like it's closer to pin 2 than to pin 1-- Again, the marker often labels the corner where pin 1 lives, not the individual pin.


pin numbers - 17

This 74HC245D "octal bus transceiver" chip from NXP has the half-moon shape on the left hand side, plus a slightly more unusual polarity marking feature. The entire front edge of the chip-- the edge containing pin 1 --is slightly beveled.


pin numbers - 18

And now here is a chip that has less of a "direct" indication of its orientations-- no dot or half-moon shape. As we discussed earlier, you can rely on the orientation of the text in cases like this, and imagine an effective polarity mark on the left hand side of the chip. Pin 1 is on the lower left hand side.

If you look very closely, you'll see that there is one additional polarity marking feature, in that this chip also has a very slightly beveled front edge.


pin numbers - 36

This is a somewhat unusual seven-yes-seven pin DIP chip. It's a neat little solid-state relay capable of switching small loads on AC line voltage (0.9 A at up to 240 VAC) from a low-voltage digital input. Presumably, it has seven pins so that you can't put it in backwards. This chip also relies on a combination of text orientation and a bevel at the side with pin 1.

Careful: That apparent "dot" is not a polarity indicator; pin 1 is still at the corner of the chip.


pin numbers - 29

Here's one more variation. There's a printed bar on the left hand side of this chip to act as a polarity indicator, taking the place of the half-moon shape.


pin numbers - 13

Here's one that we get asked about quite often: A 17-segment alphanumeric display. LED displays can be pretty baffling, because the pin 1 location is not explicitly marked, and there's no half-moon shape or other obvious polarity marker. However, the label itself is a polarity marker and it's important to remember that.

As with the previous examples that we've shown, when you orient the part such that you can read the label, then pin 1 is at the lower left. Or, as we said earlier, the effective polarity mark "goes to the left of the text." That means that pin 1 is to the left of the text, and is the pin closest to the camera, the one that happens (for this particular display) to be located beneath the decimal point.


pin numbers - 10 pin numbers - 11

Here's a 5x7 LED matrix display. You can sort of make out marks on the back side beneath the epoxy, so it's tempting to look for orientation hints there. However, our same rule applies. When you orient the part such that you can read the label, the effective polarity mark is on the left-hand side.

In the left photo, where the display is upright and the label is visible, pin 1 is beneath the lower-left corner. In the right photo, where the label is visible but the part is upside down, pin 1 is visible on the lower-right hand corner.


pin numbers - 26

Sometimes you'll come across very different looking chips with very obvious polarity markers. This chip from Agilent has a gold stripe on the upper left hand corner.


pin numbers - 35

Sometimes a chip has a notched corner to indicate where pin 1 lives. The white silkscreen on the circuit board shows an exaggerated picture of this notching, by the lower-left corner.


More chips

The 486 is a good example of a chip with a notched corner, while the 68030 has a gold stripe to indicate pin 1.


pin numbers - 25

This Broadcom chip has a dot by the corner with pin 1, but that's a pretty subtle mark. If your chip is already mounted to a board, that can provide some better information to verify the orientation. For example, pin 1 of this chip is also marked by a white dot on the circuit board, and the other three corners have a mark, as though those corners were un-notched.


pin numbers - 22

Here's another chip that's somewhat ambiguous. Pin 1 is clearly marked with an arrow on the circuit board. If the chip were loose it would be a little less clear because not only is there a dot by pin 1, but there is also apparently a dot by the opposite corner. It may be just a coincidental mold mark, but it's still potentially confusing.


pin numbers - 30

And here, a simple dot to indicate the orientation.


This is far from an exhaustive list, but is meant to show off some of the common ways that chip orientation is differentiated. If you have corrections or links to other interesting chips, we'd welcome them in the comments.

 

Faking it: seven-segment displays

7-segment - 14

A sordid tale, starting in the bedroom, involving batteries, deceit, cheap tricks, LEDs, and a pot.


It started innocently enough. A family member hinted that a good way to keep warm on cold winter nights was with a heated mattress pad-- more sensible than heating the whole house.


Winter came, it got cold, and we got our mattress pad.

7-segment - 01

The heated pad has a simple digital controller, where you rotate the dial to set the temperature, on a scale of 1-10, or really, L-2-3-4-5-6-7-8-9-H. So far, so good. (And it's comfy warm, too.)


But, then we took a closer look at that LED display:

7-segment - 02

What seems to be a digital seven-segment LED display is actually a rear-lit cutout in the shape of a seven-segment display, with one cutout in the shape of each number. The rotating dial just masks the other shapes so that you only see one at a time.

In other words, it's about as digital as blip.


The whole bezel is rear lit by an LED driven directly off of the AC-- you can tell from the blinking. (Driving LEDs from line voltage is common in consumer electronics; it works reasonably well if you have a big series resistor.)


Somewhere around this point we went from saying "WTF?" to "What the heck!" -- because it's a clever cheap trick, and if they can do it, so can we.

Sure, we can imagine a few cases where something like this could be genuinely useful, either as a front panel indicator or perhaps as a stage prop. But mainly we just wanted to make our own it because it's hilarious.


7-segment - 04

We'll scale our dial to turn a standard 5 k pot, so that our fake digital display can do something useful.


Next, to design the bezel:

7-segment - 05 7-segment - 07
7-segment - 06 7-segment - 08

We laser cut the parts-- black and clear plastic for the number plate and plywood for the dial/knob. The black plate fits over the threads of the pot, and the big wooden knob press fits onto the shaft of the pot; the pot turns when you turn this dial, revealing a single number beneath.

You can download our pattern here (8 kB PDF document). It's pretty simple, but if you want to play with the mechanism, you can print out both parts, grab a pair of scissors and a brass brad, and assemble it like we did in this project.


Next, we need the LEDs. For maximum fancy (without using actual seven segments!) we got out the fat LEDs:

7-segment - 11

Two LEDs each, blue, green, yellow, orange, and red, to backlight the positions between L and H. We powered it from a 3xAAA battery box, and hooked it up on a breadboard to figure out the right resistor values to drive the LEDs efficiently. (Also, looks neat in the dark.) The four blue and green LEDs are independently driven off of the 4.5 V with their own series resistors. The two red LEDs are driven in series with a resistor, and that setup is used for the yellow and orange LEDs as well.


Then, we wire up the LEDs in a circle, using the same circuit:

7-segment - 12

7-segment - 17 7-segment - 15


And then we can install the black and clear number plate:

7-segment - 20


7-segment - 21 7-segment - 22
7-segment - 23 7-segment - 25

And there you have it: A five-color LED-lit fake-seven-segment pseudo-digital pot, based on advanced mattress pad technology.

Mailbag: Moving from breadboard to protoboard

breadboard - 1


Ryan writes in,

"I have a question about moving a project off a bread board and onto a project or perf board. Basically what is the best way to do without a lot of rework? This will be my first time doing this and I was just wondering if there were any best practices so that the final product looks clean and organized and I don't have mountains of solder on the back side."


And it's a good question.


It turns out that we don't actually use solderless breadboards all that often-- most of our physical prototyping is soldered directly on perfboards, like so:

Cylon circuit close up


However, that's an acquired skill, and there is indeed a bit of a leap from breadboard...

DarkPumpkin - 01


... to protoboard:

DarkPumpkin - 03


Now, it turns out that there's actually a neat and happy medium from (of all places) Radio Shack: A protoboard shaped and wired up like a breadboard.

breadboard - 2

Ours is in older packaging, but catalog number 276-170 is still around, still cheap, and as they say, "available at most stores."


breadboard - 3

The bottom side of the board has the same wiring as a typical solderless breadboard, albeit with only one stripe down each side.

This layout means that you can usually duplicate your breadboard circuit exactly, soldering as you go, to make a permanent copy of your breadboarded one.

Doing so, you also get familiar with the process of soldering parts together on the protoboard-- a useful skill, especially if you ever need to build something that doesn't fit on a breadboard so easily.


breadboard - 4

Here's the top side of that board, which might look more familiar to breadboard fans.

Love that vintage Archer branding, which was lost somewhere along the way.

 

A scarf to aid your search for terrestrial intelligence

arecibo 2


The Arecibo Message, one of the most famous messages transmitted as part of SETI, loosely translated, says: "Hi! We're intelligent! We're made of meat! Here's where we live!"

Binary designs like the Arecibo message are popular with knitters and cross-stitchers since they can be pixelated easily. We found a pair of fingerless gloves, based on a muffler pattern. We think this type of binary pattern would be good for the message as well. It has also been made into a cross-stitched bookmark.

We implemented the embroidered pixels as columns of satin stitching in a single color. The original binary message didn't have any of the color coding that people have added to help explain it, and it seems more elegant to keep it this way.

We machine embroidered the pattern on both ends of a piece of linen about 14" x 76". The linen is then sewn together on the back and at the ends, and turned right side out. The edges are stitched down to help it lie flat.


arecibo 1


The embroidery design is about 3.5" x 11.5". We're providing a couple of different embroidery formats for those with access to machines as well as a .pdf for cross stitch, hand embroidery, laser engraving, or whatever else you can think to do with it.

  • .DST embroidery file (36 kB)
  • .PES embroidery file (75 kB)
  • .pdf file (4 kB)
If you are inspired by the message or use one of the patterns, we'd love to see the results in the flickr auxiliary.
