DIDJ Composite Video Out

June 30, 2010 by Mike Szczys 8 Comments

[Nirvous] managed to get composite video out working on the DIDJ. He knew that the CPU had the ability to generate the signal, and that similar devices already had this capability. After studying some DIDJ teardowns he figured out which connection on the processor should provide the appropriate signal. Next was the firmware side of things and after sifting through a lot of code he was pleased to find a flag that looked like it would enable video out. Some cross-compiling, soldering, and a low-pass filter got it to work.

If you’ve been hacking around on the device you might try this. The CPU uses a ball grid array so soldering is a bit difficult. We covered a BGA soldering trick that might be just the thing so check it out before you retreat into your soldering-fortress of solitude.

NES Controller To USB Gamepad

June 30, 2010 by Mike Szczys 24 Comments

Regular Hackaday reader [Osgeld] is at it again with this USB conversion for an NES controller. This is a ubiquitous hack that we started seeing very early on, sometimes involving an adapter kit, and other times including things like a thumb drive and USB hub. But this time around is truly a bare-bones version. He’s using an Arduino but it’s really just an AVR ATmega168 running the bootloader. We’d wager this can be done with an ATmega8 just as easily. Grab a couple of diodes (we never seem to have the 3.6v zener diodes around when we need them), a couple caps and resistors, a crystal and you’re in business. The hack wires each button to a pin and implements a keyboard HID that can be mapped for any purpose you desire.

Holy Robin Trap Batman!

[Matt Meerian] introduced us to his kludge of cardboard, tape, mirrors, and electronics in the form of a clever non lethal robin trap. Whenever a pesky robin would enter the box, a sensor is triggered, the solenoid drops a lid, and the bird is contained (and we assume taken far away after that).

Of course the plan backfired; we wont spoil what happened, but you can click the link above to find out.

How To Design Your Gears

June 30, 2010 by Caleb Kraft 32 Comments

[Dustyn Roberts] takes us through the process of designing gears for a specific application. Using Inkscape and Ponoko.com [Dustyn] takes us from equation to physical gear. While there is a plugin for Inkscape that allows you to basically drag and drop gears, this writeup will take you through the math to get exactly what you need. Those laser cut wooden gears are pretty cool looking too.

Power Cycling A Problematic Modem

June 29, 2010 by Mike Szczys 53 Comments

[Gigawatts] struggled against a shoddy Internet connection for quite some time. Changing modems, having the line serviced, and spending far too much time on the phone didn’t do any good. In fact, the only thing that fixed the problem was power cycling the modem once it stopped responding. His solution was to automate the power cycling process. He added a cron task to his router which is running DD-WRT, a favorite firmware alternative for hacked routers. The script monitored the WAN connection and when it went down it would toggle one of the serial port pins. He whipped up an outlet box with a relay in it and used that serial pin to cut the power going to the modem. A workaround yes, but it was the only thing that brought an end to his frustration.

Acrylic Hackintosh Housing

[Rui Gato] needed a powerful yet portable machine for his performances. If it’s on stage shouldn’t it look good too? We loved watching him construct an acrylic case for his setup. He’s skilled with a rotary tool and the work he put into the case fan grill alone is impressive. Video after the break.

FPC Arduino

June 29, 2010 by Mike Szczys 30 Comments

Seeed Studios has a new version of the Arduino that they’re calling the Seeeduino Film. Instead of the traditional fiberglass substrate they’ve used a resin material to produce a Flexible Printed Circuit (FPC). In addition to its flexibility their aim with this prototype was to keep it modular. From what we can see each of the four squares is a different component in the Arduino system. The photo above has the USB interface on the nearest node, then the power regulator, the microprocessor, and finally the remaining peripheral connections. This material can easily be cut with a pair of scissors so the programming section can be removed once the firmware is burned to the chip. It will be interesting to see final pricing and package options. We wouldn’t mind having an FPC ATmega168 breakout board around, but specifially this would fit nicely in a watch band if you were building your own wristwatch.
