This circuit is used to create a simple "edgebot" sumo robot. Being an edgebot refers that it will repeat the same backup/turn/go forward action when it's single edge sensor detects the edge of the ring. This version of the circuit is quite simple, and always turns the same way.
Thursday Cool Links: Laser Origami, RFID...

March 7, 2013
Thursday is the new Wednesday, did you know? According to the new bylaw, you might have heard about this one... Okay, to be honest, we are late with the post... But doesn't that make it more exciting?! I bet it does, so here we go, the long-awaited links:
 |
Laser Origami We've got lasers. We like lasers. What's really cool is how _these_ guys bend lasers to their will to do 3D fabrication. Kudos - very impressive! |
|
Building An Active RFID People / Asset Tracking System With Mesh Networking RFID tracking system using mesh networking! Lost keys and people, tag, you're it! Never get lost again. |
 |
Unstable Matter: A Giant Moving Surface Containing Thousands of Steel Ball Bearings A clever take on a rain stick, and really fascinating to look at. I wonder how some magnets underneath would alter the movement... |
 |
A DIY digital camera made with cardboard and an Arduino DIY craft paper camera using Arduino UNO, are a lithium battery pack, a Snootlab SD card Arduino shield, and a JPEG color camera TTL interface. Rrrreally interested to see how that's made, hopefully the makers will release the code and more details soon. |
 |
100 LASERCUT JEWELRY DESIGNERS This is one MEGA link to see what's out there in the world of lasercut jewellery and hunt for ideas, materials and shapes. |
That is all for now, stay tuned, stay warm, stay un-snowed on, or the opposite if you prefer, and we'll see you next week.

We've been having fun playing with the L293D driver chip. It's one of those things to see how much you can make it do by itself (like with any BEAM application!). Grant McKee has been experimenting with some simple additions to the chip to make it (unto itself) a suitable brain for a simple mini-sumo […]
Friday New Product: FETs
What we have today are not Fairly Expensive Tortillas or Fortunately Edible Theremins, but Field-Effect Transistors. If you know what it is, I will leave you to explore: 1RFZ44N N-Channel FET $2.50 The IRFZ44N is a very powerful useful N-Channel FET, with only 0.0175ohms resistance pushing 20 amperes at 5V! FQP27P06 P-Channel FET $0.95 A […]
Friday New Product: BusBoard Protoboards
Wee, more protoboards! Now this is the last batch, we don't got no more. Next time it will be something else, I promise. PadBoard-1 Pad-per-Hole, 80x50mm Solder Protoboard $3.75 A tight and tidy one-pad-per-hole, plated-through, double-sided board. Ideal for wildly-wired, small projects! PadBoard-2, Pad-Per-Hole, 80x100mm Solder Protoboard $6.82 For the ultimate in protoboard flexibility, here's […]
