How-To: Open source intervalometer for Canon, Nikon cameras

Instructables user peterdr has put together a really excellent tutorial on how to build his CT-1 open-source hardware intervalometer for Canon and Nikon digital cameras. There's more info about the project at his personal website, and a parts kit is for sale on Amazon.com.

Solar-powered miniball

It may look like some futuristic Christmas tree ornament, but the miniball is part of the BEAM robot family of "rollers." A miniball is a motorized hamster ball that, sadly, you don't see in the wild too often. Solarbotics used to sell a miniball kit. This Instructable, by MAKE contributor and Solarbotics intern, Jérôme Demers, shows you how to make your own.

How-To: Custom wooden case for wireless charging mat

Instructables user jvalal didn't like the look of his Powermat inductive device charging station, so he stripped out the guts and "re-skinned" it with a handmade wooden case.

The EyeWriter

I'm thrilled to share the EyeWriter with you all:

Behold the latest ocular assault weapon from the Graffiti Research Lab, openFrameworks, The Fat Lab and The Ebeling Group: The EyeWriter. It is a low-cost eye-tracking apparatus + custom software that allows graffiti writers and artists with paralysis resulting from Amyotrophic lateral sclerosis to draw using only their eyes.

The goal of the hardware component of the EyeWriter project is to make the most simple and inexpensive eye-tracking head-set possible to use with the "EyeWriter" software suite. Obviously, there are numerous ways to make eye-tracking hardware. Many of these designs, especially those produced for academic research projects (Open Eyes ), have already been published openly on the internet.

Our functional design specifications are as follows:

1. The EyeWriter should be as inexpensive as possible
2. The fabrication and assembly of the system should require only common hand tools
3. Whenever possible components and parts should be available for purchase locally versus online
4. The camera should produce 640 x 480 NTSC video
5. The camera should be sensitive to near-field IR light
6. The camera should not auto-iris (or auto-iris should be disabled in the camera's driver).
7. IR LEDs should be used to illuminate the pupil

Beyond that its up to you... this instruction set details a solderless variation of the EyeWriter that uses a hacked PS3 Eye and a pair of stunnas we bought on Venice Beach and suggests other possible EyeWriter configurations.

Yes, that's right, watch TemptOne tag buildings (with light) even though he can only move his eyes. We live in the future, and this project makes me feel so warm inside. The whole project is open source.

How-To: Pirate TV

Jon Cohrs writes:

Tired of the blocky, JPEG-like resolution of digital television? Do you long for the days of RF modulation and regulated-yet-unregulated content? Do you simply have the desire to toss your converter box out the window and make use of those rabbit ear antennae that are just lying around? If so, then you might be interested in becoming a savior of analog television! This Instructable will show you how to create your own fully-fledged low-power analog television channel, with any video source(including your computer) as a source of content.

We created one that went live the minute analog tv went dead. We're still the only analog station in NYC, but please join us in making more!!

Awesome kidnapped mermaid costume

From Instructables user ModMischief comes a great tutorial on building this impossibly clever one-person trompe l'oeil costume. As she says, "[w]hy choose between dressing as a sexy mermaid or a scary pirate when you could be both!"

Etch at home: Wii Nunchuck Arduino adapter

Don't want to cut the cable on your Nunchuck or buy a teeny circuit board to do the trick when you have etching capability at home? Instructables user dany32412's Nunchuck Arduino adapter tutorial uses pretty much the same layout as Tod Kurt's, but you make it yourself!

Beautiful scrap wood butcher block table

I love this. Instructables user wholman has gathered together a bunch of scrap wood from "dumpsters, back alleys, vacant lots, abandoned buildings, recycling yards, and architectural salvage centers" and laminated it together using all-thread. Then he's very carefully smoothed and polished only one side of the finished block, leaving the underside rough to show off the process. Beautiful.

AIRduino guitar

Ever wished that when you play air guitar, it would make real sounds instead of just the ones from your best death metal face? David Fournier, Jean-Louis Giordano, Monireh Sanaei, Maziar Shelbaf and Gustav Sohtell are here to help. They build the AIRduino guitar, a wearable virtual instrument. Open source with full documentation, naturally. [via Fashioning Technology]

Ikea hack bookshelf bench

Randy Sarafan writes:

The nice thing about IKEA furniture is that it is cheap and easy to hack. In other words, lets say that you were to buy two cheap $30 Gorm shelving units and assembled them to discover them that one was crooked. Well then, it would be really easy to spend an afternoon converting the crooked one into a solid, stylish and symmetric bookshelf bench. As you probably just guessed, this Instructable will show you how to convert a Gorm shelving unit into a bookshelf bench. With a few extra peices of hardware and a couple of basic power tools, you could be on your way to relaxation and organization all at the same time.

District 9 SPLAT gun replica prop

Instructables user msraynsford presents this detailed tutorial on how to build a prop replica of one of those District 9 guns that makes intelligent, loving, civilized creatures explode with a nauseating SPLAT. I want one!

LED Binary Clock

Here is an interesting LED binary clock by instructables user ElevenOf9. I really like the single sided PCB, and the way the LEDs are arranged. It just looks cool!

This is the second revision of my PIC based LED binary clock. The original version was the first PIC project I attempted, it used a PIC16F84A to do both the timekeeping and control the display matrix, unfortunately it didn't keep good enough time and gained about a minute every week.

Bicycle handlebar brake lighting

MAKE subscriber Justin Shaw has posted a project on Instructables for a bike brake lighting system that features lights on the ends of a bicycle's handlebars, controlled by an Arduino and a Pololu 3-axis accelerometer. He's even offering a $35 prize to the first person who follows his plans and posts proof of a successful build.

Remote control color-changing pumpkin

Ian Lesnet submitted this cool hack-'o-lantern to our Make: Halloween Contest 2009. There's an Instructable here, a Flickr set here, and YouTube video here. It's a color-changing pumpkin full-court media press! The build uses a ShiftBrite RGB LED module, IR receiver, universal remote control, and a PIC18F2550 as the brains of it all.

DIY netbook stand

This sturdy, portable DIY netbook stand is perfect for smaller models between 7-10 inches. [via liliputing]

In a nutshell, all you need are two IKEA shelf brackets, a drawer handle to hold them together, and some vinyl cabinet brackets to keep the laptop from sliding. You'll also need a drill, screwdriver, and hammer, but I'm going to go out on a limb and predict you've already got those lying around.
