HOW TO - Turn an Arduino into an AVR-ISP programmer
Windell writes -
This morning someone asked me if it was possible to program AVR microcontrollers using their Arduino board as a programmer. I looked, and sure enough, a solution exists! This could be pretty handy, particularly if you have a Mac and/or only USB ports. Someone that is going to make this will probably also want to take a look at Atmel application note 42, which discusses using the ISP (in-system programmable) interface (PDF)...

LoveM Memory Chocolates technology sketch
Todbot writes -
Another technology sketch from my company ThingM. This time it's Valentine's Day-themed, with LoveM, a heart-shaped box of "memory chocolates".LoveM is a Technology Sketch of an augmented box of chocolates that displays personal memories on an LCD screen as chocolates are removed from the box. It attempts to evoke joy and surprise through the use of available, inexpensive technology embedded into a familiar object. It investigates what happens when we put technology in a non-utilitarian, non-game context and explores the ideas of introducing personal, intimate content into an otherwise mass-produced product.
It's also our Valentine's Day present to you. ;-)

LabVIEW routines for the MAKE Controller
Evil Mad Scientist Laboratories writes -
As evidenced by a growing collection of projects, the MAKE Controller has great potential as a hardware platform enabling computers to really do things.We won a MAKE Controller for our set of Halloween projects this year, and we're just starting to play around with it. Having spent some pondering how best to communicate with the board, it's clear that one of the barriers to more widespread use of this and other embedded systems is the lack, or perceived lack at least, of user-friendly software for programming and communication.
A number of open-source software packages, such as processing and Ruby, can communicate with the MAKE Controller using its OSC interface. However, there has been a noticeable absence of a suitable interface to LabVIEW, a program that is commonly used for interfacing to other similar types of hardware.
So, we wrote one. It's a simple LabVIEW "vi" routine for issuing (most) simple commands and queries to the MAKE controller. We've also included some example routines to help you get your blinky lights going a few minutes sooner.

HOW TO - Make a pulsing hubby detector
Daenris writes -
This project uses an RF receiver module to trigger a pulsing LED Heart when the transmitter comes within range. I made this for my fiance for Valentine's Day this year.I have yet to fully test the range, as I haven't actually taken the transmitter out of our apartment building since I just finished it today. The transmitter/receiver pair that I used is hypothetically capable of up to 500 feet, though that is the open space line of sight range. I haven't yet added antennas to either the receiver or transmitter box, but that should hypothetically improve the current range.

Lovers-only light
Someone is going for BF of the year... nicrosin writes -
This device is a Valentines Day gift I made for my girlfriend. I took a "bug tracker" toy, tweaked and re-packaged it so a couple can wear it. The light only goes off when the partner is close by. "I light up when you are near me" has never been truer.

PanoramaScanCam - "first light"
Mac writes -
Since the last update I posted, I was able to work out a number of optical, mechanical, and electrical issues. A new lens is now attached to the (heavily reworked) scanner head. They have been attached to the camera cylinder. Last weekend, I did a test operation of the PanoramaScanCam and obtained "first light". Since then, I moved the registration sensor from the scanner head circuit board to the side of the camera cylinder. Remaining tasks are the clean up of the top cover of the case, addition of a shroud to cover the scanner head, and resolving the issue of infrared light sensitivity in the scanner's CCD sensor.PanoramaScanCam™ - Link.

Atari K-9 & Circuit board night light
Joe from Grand Idea Studio's got busy over the holiday break... Here are a couple new projects to check out...
The Atari K-9 is a case modification and art installation created to pay homage to Joe Grand's first personal computer, the Atari 400 8-bit home computer, and one of his earliest pieces of software programming. It is a simple, non-intrusive reminder of home computing's early days and was designed to stay consistent with Atari products of the era.The program, entitled "K-9" (also referred to as "Electric Dog"), was written in BASIC circa 1983 and recently discovered on 5.25" floppy disk. The program was first archived onto a modern PC platform using an SIO2PC Universal Interface and then, with a series of original Atari applications running on a PC-based emulator, was compiled into a standalone binary executable. Next, the executable was converted to run on an Atarimax Flash Cartridge, thus removing the need for a floppy disk drive.
Atari K-9 - Link.
In the spirit of recycling old and/or obsolete electronics to make something new and unique, the Circuit Board Night Light was created from six non-functioning DEFCON 14 Badge circuit boards. Five boards are fastened together with L-shaped corner braces and round-head slotted machine screws to create a base for the modified head-mounted, white LED-based flashlight mechanism. The top circuit board attaches to the base via a narrow butt hinge to allow access to the inner components. Dura-Lar 0.005"-thick matte drafting paper is affixed to the inner side of each circuit board to help diffuse the light. The Circuit Board Night Light measures 4" in each dimension.

HOW TO - Build a Nintendo (NES) PC
Hatskull shows you how to build a Nintendo (NES) PC...
Ah, the Nintendo Entertainment System. Brings me back a lot of good memories: Super Mario Bros., Double Dragon, Megaman. It also brings back not-so-great memories. The agony of changing cartridges, blowing until you're dizzy and still getting nothing but a flashing screen when you start the console. When you finally got the cartridge to run, it could freak out at any time from the smallest dust particle in the connectors.Luckily, those days are gone now. NES emulators can be found for the PC. These nifty little programs are designed to run NES games as accurately as possible.

BERGFOTRON mek - homebuilt synth
Jörgen has some amazing homebuilt synths with brass mechanics...
A large part of the work in building a modular synthesizer is in the mechanics.This is also where many home-built instruments fall short of the commercial ones. I wanted my synthesizer to look as good as a commercial one, or hopefully even better. Mechanics isn't just looks, of course. It must also be rugged enough, to withstand portable use. It should also be lightweight and compact, for the same reason.Right now I have a temporary 19" rack case, that I built years ago. It takes two rows of modules, which won't be enough for all the planned modules. I will make a larger, portable case but the design isn't finalized yet.
The mechanical construction of the individual modules deserves some thought too. All my modules are based on a 1 mm thick brass front panel. You might think 1 mm is too thin, but I use 1 x 10 mm strips to brace the panels. A huge advantage with brass is that it can easily be soldered to. So I just solder strips to the back of the panel, when required.

Seeing through circuit boards
Bunnie writes -
I'm resolving some manufacturing challenges in the new chumby design and had the opportunity to use an X-ray board inspection tool. This tool is what you want to use if, for example, you wanted to reverse engineer a circuit board with buried or hidden traces. It also lets you see through the packages and inspect the quality of the wirebonds. This particular system has a feature that let you rotate the board as you inspected it so you can look at it at an angle-which is actually really cool to see live, it's sort of like flying through the circuit board. I wish I had a video of it but I didn't bring my camera into the shop today.Seeing through circuit boards - Link.Anyways, I thought those who have never seen this capability before would find the following pictures interesting and perhaps thought provoking.

Bucket mousetrap
Matt writes -
This project captures a mouse by having a solenoid (electromagnet) drop a bucket over the mouse. The bucket is triggered by the mouse interrupting one of the infrared emitter/detector pairs around the bait. The enclosure that holds the electronics is mounted directly over the bait. Ok, so the "bucket" is actually a semi-clear storage container. The clear container allows a person to see if a mouse was trapped when the container dropped.Bucket mousetrap - Link & mirrored site.

HOW TO - Make a PC board with a dremel
Botronics writes -
This is not an Instructable for a particular device or circuit. I'm using the circuit I made for an Artbot project as an example. If you need a quick and dirty way to fashion a pc board, you can cut out the copper clad with a Dremel tool. Just plan you circuit and cut away copper to form your paths. No etchent, photo plotting or even drilling needed in some cases. Of course, you can't do any real fancy and do complex circuits, but for something simple, this does the trick.HOW TO - Make a PC board with a dremel - Link.

Flashing LED Bra
Need something to do with all those LEDs that you were going to make into cartoon characters and place all around Boston?
The folks at enlightened have launched the 'nerve' bra that has 31 flashing LEDs in it and multiple flashing patterns.
While silicone is usually found inside a bra, we've used silicone on the outside as a means of sculpting the light into organic shapes with an underlying geometric pattern. This bra has a lot of LEDs (31 per side), in a full rainbow of colors, with eight different flashing patterns that can be selected by the wearer. The base bra in this example is a nude seamless type, encouraging the illusion that the skin is exposed and the light is coming from within the body. - Link
