Chuck From “Chuck’s No-Weld Recumbent Bike.” Because riding a recumbent means you have to smile like that:) As with tall bikes a few weeks ago, I’ve just hit my tipping point with recumbents: there are now too many high-quality how-to’s on this most aerodynamic style of bike to avoid adding it to my project list.

In a week, it’s that dorky time of month again: Thursday, September 18, 7PM Cafe Mundi 1704 E 5th St. (a few blocks east of I-35) (512) 236-8634 Dorkbot is, as always, a FREE event. * Meredith Johns and Carolyn O’Hara from Hawgfly show off their gore cannon * Edwin Wise is back with a […]
Nich sent us a link to his project, Dr. Pic, an all AJAX image editor. Without using any Flash, the application allows you to upload an image, do simple draw and filter operations, place text, crop, resize, and save a finished copy. Javascript is used to draw preview material to the canvas, and then the […]
This DIY RFID sheild kit for Arduino will get you started with RFID out of the bag. The kit includes a 13.56 MHz RFID Mifare Module, 13.56 MHz PCB Antenna, and 4 x Mifare 13.56 tags which together with some basic soldering skills is a nice intro into the world of passive radio sensing. via […]
This hack shows how to turn Apple’s branded white headphones into black ones in order to fool people into thinking that you are not just part of a worldwide marketing campaign. We like the simplicity of using a Sharpie to color the cables, but we wonder if your skin will when the ink sinks into […]
This interesting robot uses an Arduino and motor shield with one servo for steering and a standard DC motor for moevement. The bot is called “baratinha” which means “little cockroach” in Portuguese since it uses two micro-switches to detect if it has bumped into any obstacles. Watch the video for the full effect.

That was fast, here is s1axter’s how-to on getting the code off the Esquire E-ink’s PIC… Find a PC with a pic assember on it. Get/borrow/make a ICSP programmer (parallel programmers will work, just lead out the Vdd,Vss,MCLR,CLK,DATA pins. Remove the battery since it is only 3v and most likely you will be using 5v. […]
