Here’s an interesting kit put together just to help you work on your SMD soldering skills. It’s got 49 SMD LEDs on the front with a programming header and switch jumper. The back has an ATtiny26L and a coin cell. At only 3V, power management is essential; all of the example programs are only addressing one LED at a time (imperceptible to the human eye). If you turn on too many LEDs at the same time, the voltage drop could cause the AVR to reset. Included example programs are a scrolling marque, bouncing balls, and Conway’s game of life. SparkFun has tutorials for regular SMD soldering and using a reflow skillet. The video below shows the kit builder attaching just one LED using the heat and slide method.

Waterproof IPod Touch Video Boombox
Popular Mechanics contributor [Anthony Veducci] wanted a virtually indestructible video player that he could use anywhere. Not finding a commercial solution, he decided to build his own. He already had a large waterproof case and another for the iPod Touch. The 8″ display came from an iPod accessory. Unfortunately it was developed before Apple implemented their stupid accessory locking, so he had to use an Apple approved video cable through several adapters to get it to work. The speakers were also salvaged parts. The case was assembled using a jigsaw and a whole lot of epoxy. The speaker openings are covered with latex from a pair of gloves and everything is sealed with silicone. We’re usually trying to escape technology when we head outside, but we’ll be looking back at this the next time we need to ruggedize something.

SyncMaster, Home Made Modular Midi Controller.
[D.St-Amand] is designing the SyncMaster, a compact modular midi controller, from scratch. The design focuses on a modular build where you can swap out pieces like the one pictured above to achieve different layouts. Not only is it modular, but its very compact. Shown next to some common competitors, it looks very sleek.
Development seems to be moving forward, the pictures have been updated frequently. Lets hope to see a fully functional demo some time soon. Some more detailed information on the build might be nice as well. This may remind you of our story on MachineCollective. While there are similarities in that they’re modular, SyncMaster appears to be a much more polished and portable product. Keep us updated [D.St-Amand].
Das Uber Airsoft Gun Turret
Hot on the heels of the Wii missile launcher, Das Uber Airsoft Gun Turret is here to put our past airsoft turrets to shame. Made by [Miltron_B], this autonomous beast not only has gorgeous LED indicators, it has lasers. Three of them. Three freaking lasers. Take a moment to wipe the drool from your chin.
We’ve seen plenty of turrets before, but this one really excels in design. It features two webcams for more precision detection and tracking and when set to manual mode, it can be controlled with an XBox 360 controller. He’s posted great pictures of the process with a step by step break down. Tons of useful links are included to help you out.
Someone should construct a Portal sentry gun case for this thing and add voice clips.
Hack Guitar Hero DS Into A Guitar Controller
[Eric Ruckman] sent us this awesome Guitar Hero hack. He wanted to get a more “true to the series” game play out of his DS when playing Guitar Hero: On Tour. If you’ve seen the adapter that comes with it, you’ll understand his desires. He found a wireless PS2 Guitar Hero controller on EBay to hack.
He’s cut a hole in the controller and removed all the guts. In the picture above the DS fits in the hole to allow strumming in the correct position. The controller buttons are connected to the DS by wiring into the adapter. He’s added an FM transmitter to the controller so he can play the sound through his home sound system.

Hacking The Myvu Personal Video Player
[jongscx] picked up a Myvu personal media viewer and promptly began scheming about improvements. He decided he wanted to be able to watch any input on the device, not just an Ipod.
After some messing about with different inputs, he eventually calls Myvu to ask some questions. Surprisingly, he gets the engineer who designed the thing. The engineer turns out to be pretty helpful and is happy to help him hack the device. [jongscx] ends up finally getting it to work and posts the schematic for the world to see.
He says his hands are full with some other projects right now, but hopefully he’ll do an official write up with pictures of the final product soon.
[DrNathan] wrote in to note that [RetroPlayer] was responsible for much of the work as well as contacting the engineer.
[thanks, DrNathan]
USB Switched Power Strip
[toymotorhead] pieced together this USB controlled power strip to help with his electrical bill. His goal was to be able to have devices turned off automatically when he shut down his computer as well as powered on when he turned his computer on. Another requirement was that the USB be isolated to protect the motherboard from spikes.
The cost of the parts in total were less than $30, and consisted of a solid state relay, some fuses, and some transient voltage surge suppressing diodes. The unit only switches power off or on depending on whether or not the computer is powered up, it doesn’t control the outlets via software. He goes pretty in depth as to how everything works as well as showing nice diagrams and pictures. This should be a fairly quick and simple project, as long as you take the proper precautions for working with high voltage.
