Drop F-bombs Into A Magic 8-ball

January 31, 2011 by Mike Szczys 15 Comments

People in search of something profane to adorn their coffee table need look no further. [Wizgirl’s] magic 8-ball hack lets you change the messages inside, and her messages all include the most powerful of four-letter-words. To do so she completely replaced the message cube inside with one she built from a sheet of plastic, plastic label-maker labels for messages, and craft googly eyes to make it float… Brilliant.

The whole thing was reassembled along with the original fluid but she’s not done yet. A bit of creative case modifications leaves this magic 8-ball looking like a cartoon bomb, complete with a thick white fuse. She’s now the proud owner of a magic f-bomb.

[Thanks Osgeld]

Evalbot Nunchuck Control

January 31, 2011 by Caleb Kraft 16 Comments

[Martin] got his evalbot recently and wanted to try controlling it with his Wii nunchuck. After some trial and error, he finally got it working. He’s shown that controlling the bot with the nunchuck was actually pretty simple, but there are some other tips that could be pretty helpful in the process. One was the fact that the point where he’s taking power for the nunchuck could easily be shorted on the motor. He wrapped his in tape, but we could see this little bug pestering us for a while before we figured out what it was. You can download his code and see his build process on his site. Be sure to catch the video of it working in both accelerometer and joystick mode after the break.

Insane Covert IR Illumination

January 31, 2011 by Caleb Kraft 37 Comments

[Onironaut] over at lucidscience sent us a link to his latest project, some IR illumination panels. At first, we were mildly enticed by his usual high standard of photography and description. It was just an array of LEDs though. Still, we kept hitting the “next page” button because he goes into such great detail. Then we saw version two. Instead of simply being an array of IR LEDs mounted outside for his security camera, he has mounted 1536 IR LEDs inside an old flat panel monitor. That’s a fake monitor producing 180 watts of IR light, and we think that’s even at half power! He replaced the screen of the display with one way mirror, so you would have no idea that it isn’t just a normal screen sitting on his desk. Great job as usual [Onironaut].

SNES Arcade Controller

[Daniel] is making a mini arcade cabinet with an SNES housed inside. He wanted to build an arcade controller for it and chose to construct something from scratch instead of destroying an original piece of hardware. We can almost feel you guys sighing with relief at that one. He sent us some nice photos of his build and pointed out that he’s using one of the Evilmadscientist AVR boards housing an ATtiny2313. The arcade buttons are readily available at sparkfun. The source code for this project is available after the break.

Snail Mail Notification System

January 30, 2011 by Caleb Kraft 29 Comments

[Mime] lives on one of the upper levels of an apartment complex. The mailboxes, being located at the ground floor can be somewhat inconvenient to check regularly. [Mime] decided to rig up a device to let him know when his mailbox had been accessed. He started with a wireless doorbell, thinking he could use the door side button inside his mailbox as a trigger with only some slight modification. On the receiver side, he wanted an LED to flash, letting him know that it was time to check his mail. One simple circuit and a self blinking LED later and the whole setup was finished. Great job [Mime]

Jeri Getting Her Own Show?

January 30, 2011 by Caleb Kraft 35 Comments

[Jeri Ellsworth] has been very excited about this new opportunity. She sent us a “pilot video“, so we’re assuming that there will be more to come. In the pilot, she explains how to build a musical art installation that will play music when a viewer is in position. She covers several different ways to detect the presence of the person, ultimately landing on using a PIR sensor for detection. We can’t wait to see where this show goes, but we hope she continues to do her own hacking videos as well.

Hands-on With EZ430-F2013

January 30, 2011 by Mike Szczys 23 Comments

At the beginning of the Month we came across a coupon code for a free eZ430-F2013 development stick. TI has given these things now and again so we took the opportunity to acquire one. It arrived yesterday and we’ve spent just a bit of time looking it over. Above you can see the first project completed; Hello World on a salvaged Nokia cell phone screen. Join us after the break for our thoughts on the device, as well as more pictures and details.
