Wireless accelerometer project [Jerome Demers] sent us his extremely detailed semester project. The two part system consists of PICs connected to XBee modules and accelerometers. By using the device a coach can monitor an athlete and correct their minute mistakes. Did we mention [Jerome] was very detailed? He also goes into the particulars of designing [...]
Cockroach pimps a sweet ride This giant Madagascar hissing cockroach rides proudly atop his three-wheeled robotic platform. This project from several years ago is new to us and our reaction to the video after the break is mixed. We find ourselves creeped out, delighted, amazed, and saddened. The cockroach controlled robot uses a trackball type [...]
Dingoo A320 RAM upgrade [Stephanie] beefed up the hardware on her Dingoo A320. She enjoyed the features that the A320 handheld gaming system offered, but wanted the 64mb of RAM available in its bigger brother, the A330. A comparison of the two led her to believe a swap might be possible and after sourcing a [...]
(mini)How-To: Refill your DTG inks The number one and number two things asked after presentation of our DIYDTG were… “How does it hold up in the wash?” and… “How did you change out the inks?” While we’ve explained the first several times (regular ink washes out, DTG ink gets a little lighter but survives) we [...]
Getting your message across at commencement [Yomagaocho] is graduation from Northwestern University on June 18th (wow that’s late in the year… they must be on quarters). He decided to spice up his mortarboard for the commencement ceremony. A normal message wasn’t good enough, and even a solar-powered diorama wasn’t going to suit him. Instead he [...]
Augmenting a cheap Android MID We’ve been on the prowl for a low-cost Android MID that, you know, works well. We were originally excited by the Eken M001 but early reports about poor battery life, coupled with the fact that it only runs Android 1.6 soured our interest. [Carnivore] didn’t let those things turn him [...]
Drawbot produces portraits… very slowly This robot artist, the Drawbot, produces images using an Arduino and Processing. A piece of paper is attached to a wall as a stylus connected to a couple of stepper motors scribbles out patterns that gradually become the image seen above. Each drawing is different and can take several weeks [...]
Adding Compact Flash to an old sequencer [Shoji Ito] has a beloved sequencer that went out of production ten years ago. Unfortunately the storage options are also 10 year out-of-date as SCSI is the stock option for storing his loops. Using a series of adapters he added Compact Flash storage to his Akai MCP-2000 Classic. [...]

Motorcycle current gear indicator [Vassilis Papanikolaou] just finished building a gear indicator for a motorcycle. This quite a simple implementation compared to some of the other vehicle information displays we’ve taken a look at. You should be able to build and install your own without breaking the bank. An ATtiny25Â microcontroller reads data from a couple [...]
