This is going to change the way you play with yourself. What if every time you got a little bored you reached for your belt rather than your smart phone? [Cunning_Fellow] may be doing that more often now that he finished this slick-looking video game belt buckle which plays the classic Asteroids game.
It isn’t just an intriguing concept. The build was pulled off at a very high level of quality… this thing should have no problem standing the test of time. First off he had to figure out if it was even possible to run the game at a respectable frame-rate. Cheap 320×240 LCD screens don’t have a frame marker (think of it as a vertical sync signal with can be used as an interrupt for the microcontroller). But he thought it was possible that the frame marker pin just wasn’t connected like on more expensive screens and he was right with at least one model he acquired.
With that out of the way he laid out and etched a beautiful double-sided board to house all of the electronics. But he still needed a case. To get a one-of-a-kind look he masked and etched a sheet of brass. Once cut out and folded ti gives a wonderful look and protects the electronics inside quite well.
For some ungodly reason, [Scott] has a friend that wanted a ‘sexting themed’ Halloween costume. We won’t try to make any presumptions of the creativity or mental stability of [Scott]’s friend, but the SMS scrolling LED belt buckle he came up with is pretty cool.
The belt is based around a $13 scrolling LED belt buckle [Scott] found online. There was a problem with the belt buckle, though. Thirteen dollars means [Scott] didn’t get a whole lot of features with his buckle, so there are only 3 buttons on the entire device: letter up, letter down, and enter. Instead of pressing a button 80 times to get a lowercase ‘z,’ an Arduino was thrown into the mix to take care of all the button pressing.
The Arduino sketch could now input any message into the belt buckle in a matter of seconds. All that was left to do is taking care of the SMS to text part of the build. For this, [Scott] used the Sparkfun USB Host Shield and a custom Android app. Whenever an SMS is received on the phone, the message is sent through the USB shield to the Arduino and output on the belt buckle.
We won’t make any assumptions about the content of the messages during the Halloween party, but at least the video demo of the build is family friendly. Check it out after the break.
