Radio Assisted Drawing Device

An exhibition just wrapping up at the Russian Frost Farmers Gallery in New Zealand presented an interactive artwork hack. Called the Radio Assisted Drawing Device (R.A.D.D), it is a plotter that mounts on the wall. It isn’t computer controlled, but rather relies on a remote control with two sticks to move the plotter Etch-a-Sketch style.

A clear gantry mounts vertically and travels along the top edge of the wooden backing. A slot cut in the acrylic steadies the plotter and allows for smooth vertical movement. Obviously built by hand, the mechanics seem to have tight tolerances for precise movements of the stylus. See the exhibit in the video after the break.

Wouldn’t you love to have one of these on the wall at your next party? It adds a whole new spin on a guest book.

Tauntaun Costume

[Scott Holden] went all out this year and built an amazing Tauntaun costume. The Tauntaun from Star Wars was massive, standing 8 feet tall, and usually carrying a rider. [Scott] wanted to make it the correct size, and ultimately pulled it off. He had to build custom stilts to get the leg angle correct as drywall stilts were too straight. The rest is mainly pvc and fur. We think he did a fantastic job on this. The effect is quite nice, and we can imagine that in person it is even better.

Take note at the bottom of page 3. Apparently, he got pinned in the costume in his workshop and almost had to spend the night on the floor in the costume. That’s pretty wild, at least he was warm.

Radar Detector Tester

November 15, 2009 by Caleb Kraft 38 Comments

[Blacklight99] made this cool tool. It is a tester for those radar detectors that people keep in their cars. Though this seems like it would rarely be a tool we would need, it’s an interesting project. Some speed guns that the police use have a “stealth” mode that makes them invisible to some detectors. This tool can tell you if your detector is vulnerable to this. While this really is just a complicated flashing LED, he notes that it could be taken further to be made into a detector that is programmable and not vulnerable to any of the stealth modes.

Bulbdial Redux

November 15, 2009 by Jakob Griffith 9 Comments

[Taufeeq] sent in his “Circle of Light” bulbdial clock. You may remember when we showed you Evil Mad Scientist’s version a while back, and [Taufeeq] did use it as a base but he’s added some of his own little touches. Some of the changes include using a PIC with an RTC chip instead of AVR, which allowed him to shrink the board down small enough to fit behind the clock face, rather than on front. He’s even zipped everything up conveniently to help you build your own.

R/C Lawnmower

[Johndavid400] built this incredible looking R/C lawnmower. After spending some time repairing broken R/C cars, he wanted to move on to something a little more useful and powerful. He decided to build a mower. He’s using a transceiver set from ebay, with an Arduino interpreting the signal and outputting to his custom motor board. In the video after the break, you can see that the mower looks responsive and quick. He does note, however, that he had some glitches early in the process that left him with a runaway mower. We covered a very similar mower ages ago that used a wheelchair as the base.

[M]ouse: A PS/2 To C64 Adapter

[svofski] has a friend who is a pixel artist. They really wanted to try out their skills on a c64, but were missing a mouse. The original mouse for the c64 was not only serial, but used a different method of communication than more modern mice. [svofski] built this adapter to translate the ps/2 data to something the c64 can use. The writeup describes the build in detail and even has the PCB and source code available for download.

DIYLILCNC: Do-it-yourself CNC Mill

November 13, 2009 by Phil Burgess 39 Comments

DIYLILCNC

The DIY LIL CNC project is the newest member of the homebrew fabrication scene. This is a three-axis CNC mill that can be built by anyone with basic shop skills and about $700 in their pocket. Many of the materials can be acquired from the likes of Home Depot: the basic framework is assembled from Masonite, while other cost-cutting measures include the use of skate bearings and a common Dremel tool for powering the cutting bit. About half of the cost is for the HobbyCNC driver and stepper motor package that runs the show.

The instructions for the DIY LIL CNC are distributed under a Creative Commons license, allowing for modification and distribution with few restrictions. They’re well-written and quite thorough, including all patterns and a complete bill of materials with suppliers, part numbers and costs. As documented, the ’bot can produce parts up to 12 x 14 x 2 inches, but the project’s creators offer some suggestions on adapting the design for larger work. It’s not self-replicating like the RepRap aims for; you’ll need access to a laser cutter for some of the parts. If you can clear that hurdle, this looks like a great introduction to CNC production.
