Fresh hacks every day
If your next project needs the ability to play MP3s but you don’t have a lot of room to spare in your enclosure, [Boris] has just the thing you need. His tiny embedded MP3 module supports playback of up to 65,536 songs or as many as you can fit on a 16GB microSD card, which isn’t bad in the least. The module relies on a PIC24F for input and control, while a VS1011 handles all of the MP3 … [Read more...]
Arduino + PS2 controller + R2D2 Here's an unbelievably real-looking R2D2 replica driven by a PS2 controller with an Arduino inside that plays sounds from the movies. Too bad we couldn't find any more details about it. [Thanks Bill] Server build time-lapse [Justin] and his colleagues spent five days upgrading their server by building a 29-unit cluster. Lucky for us they set up a … [Read more...]
[Fabio Varesano's] new Arduino compatible board packs a full power punch in a ultra compact layout, measuring at 20.7x15.2 mm, the Femtoduino is probably the smallest 328 based Arduino compatible board around. Most of the staples are present, an QFN atmega328, an MIC5205 low dropout regulator good for a couple hundred milli amps, 16MHz ceramic resonator, reset, power indicator and pin 13 LEDs, but … [Read more...]
We love arcade games. Who doesn't? We feel that the "arcade" feeling just can't be replicated in any other form factor than an arcade cabinet. [Moslevin] must feel the same way too. He has built, what could possibly be the worlds smallest arcade cabinet. Aside from a coin mechanism, it is fully functional. It is an ATMega328p running his own custom software. The games he has available are Tetris, … [Read more...]
This tiny bot wants to go inside your body. That's right, it was designed to travel through veins. The little bot has no on board propulsion system. It is controlled by a magnet outside the body. See those little spines? Those straighten out to keep the bot in place when it isn't supposed to move. Creepy right? In all the articles we've seen on this bot, there aren't any details about what … [Read more...]
Here's an interesting concept, the bot pictured above has no internal control mechanisms. His claims to have built the smallest bot are dubious, considering it requires a much larger control platform to function, so lets just set that aside and look at how it works. The bot itself is basically a hollow box with a hinged manipulator mounted on it. He has then built a modified CNC type structure … [Read more...]
[tioguerra] helped make these tiny bots for the World Robocup 2008 in china. There's tons of information on the Mixed Reality forum, but you might be specifically interested in the bot section. There are breakdowns of different aspects, such as charging and IR communication, as well as some great photographs of the unit along with a smaller one. The construction of the robot seems so nicely fit … [Read more...]
