SparkFun Releases RGB Button Controller

SparkFun has been selling button pad parts for some time and we used them in our RGB door lock project. A excellent part, but you needed to implement your own interface to use the boards. SparkFun has just released two additional versions to make it easier on builders. The first is their Button Pad Controller USB. It has a 4×4 grid of buttons lit by RGB LEDs and a USB interface. This board can be expanded using the Button Pad Controller SPI. The SPI bus means it should be easy to add the button pad to embedded projects. This newest release puts you much closer to building your own RGB monome clone or other custom controller than ever before. The unit pictured above is their own project and they have no plans on selling anything like it.

Radio Controlled Sphere

[prabbit22m] has written an instructable on how to build a radio controlled sphere. The mechanism is fairly simple, with one drive motor, one servo and a gyro for stability. To turn, the servo shifts the center of gravity off to one side. You can see that the system works pretty well in the video above. If it didn’t have that gyro, it would be insane, believe us, we’ve done our own experimenting. If you like this, but want more features, check out this one that has a camera and takes pictures wherever it goes. We can’t forget Swarm either. The autonomous swarm of robot spheres. Of coarse [prabbit22m] might have the best idea of all. Dress it up as a regular ball to mess with people.

Haptic Compass

[eric], inspired by this Wired article, built his own haptic compass. Named “the clown belt”, it is a belt with 12 little vibrating motors mounted evenly all around. A digital compass vibrates whichever motor is closest to north at all times. This basically gives the owner an extra sense.  He doesn’t go much into his own experiences, but the Wired article mentions “dreaming in north” and feeling strange once they finally removed it. Precise direction senses may not be super power worthy, but they would be cool.

Mobius Circuit

We don’t want your brains to explode, so just trust us that this is a truly one sided circuit. Being a mobius strip means that this circuit has uber geek bragging rights. Beware, your friends who have never heard of a mobius strip will argue until they are blue in the face that there are two sides to it. The circuit they chose was fairly appropriate, an LED “chaser”.

Wireless TAC-2 Joystick

[Aki] had a broken TAC-2 joystick that was just begging for some new and improved use.  Since it was the cable that was broken, [Aki] had the idea to make it wireless. He designed custom boards for the transmitter and receiver. Each is controlled by an ATTiny2313. He fitted it with the stock connector so it could possibly even still work on a commodore 64. He hasn’t tested that yet though.

Laser Pup

[Joe] sent us this project called Laser Pup.  After seeing many other projects with the ioBridge like beer pouring and dog treat dispensing, he wanted to make his own. His project allows him to play with his dog via a ceiling mounted laser pointer. We know, you were hoping for something more along the lines of Laser Cats, but this is still pretty cool. He built a web interface specifically for the iPhone to control the laser, room lights, and show a live feed of the puppy playing. You can see a video of it in action after the break.

WiFi Streaming Radio Update

Since our last post about his WiFi Streaming Radio Project, [Jeff] has been hard at work to release part 8 of the project where he adds tuning control to the radio. Interestingly enough, the addition of the tuning control only requires a potentiometer and the completed AVR LCD board from part 7. After wiring the potentiometer to the analog to digital converter on the AVR and adding a few lines of code, the radio can now be tuned quickly and easily. In addition to thoroughly explaining the hardware changes, [Jeff] details the configuration changes required to the OpenWRT framework so that bidirectional communication between the router and AVR is possible, allowing the tuner to function properly. Be sure to check out the video above to see the tuner in action.
