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 […]
Cool Link Wednesday: Lights, Lamps and E...

It's officially hot outside. So if you're looking for an excuse to take a break, check out this week's batch of cool links:

Artist to Cover Bay Bridge in Programmable LEDs The idea is to cover the San Francisco area Bay-Bridge with a bristling of white LED pixels. The conceptual video looks great, but having spent time in SF, we're wondering cool they'll look through a light fog? (Serendipitous pun, there) |

Using the Codeable Objects Processing Library to Make Purdy Lamps This is a pretty comprehensive tutorial that shows you how to design some nifty lamps from the open-source Processing programming language and then cut and assemble them with the help of a laser cutter. Give it a look - it's a decent walkthrough, and the results are stunning. |
 |
Salt and Vinegar Etching This is pretty clever - you can use Vaseline and a bath of salt and vinegar to remove the copper from copper fabric, to form patterns, decorations, or even make your own circuits and sensors. It's a brilliant DIY approach using really simple materials to get fantastic results. |

Big List o' Robot Films Yeah, we get it. It's freakin' hot outside, and at the end of the day you just want to plunk yourself down on the couch and watch a movie to relax. Thanks to Wikipedia, here's a full list of robot-themed movies. My personal recommendation? Sky Captain and the World of Tomorrow. |

BEAM Robots Who says BEAM is dead? Okay, so maybe this particular site hasn't been updated in a couple years, but it still has some fantastic content worth sifting through. The authors from this site are still active on the Yahoo BEAM Group, though, which still sees frequent activity. |
And after you're all cooled-off, get back out into the sun! Especially in places like Calgary where we only get warmth twice a year, it's important to get out and enjoy this 'sun' stuff while it lasts.

Everyone is familiar with paracord bracelets - the cleverly woven wearable survival device that instantly unravels into many meters of useful and super strong nylon cord in case of necessity. These are useful for outdoorsy types, but what if you are an indoorsy type with a lot of electronic emergencies? Or a geek in need […]
New Wheels
Remember those bad-boy wheels you saw on Strongbad? Well, they're now available! But be warned - we don't have the sleeve to fix the 2mm shaft to 1/8" hole diameter gap, so you'll have to improvise something yourself. Otherwise, your robot will have a bit of a lope to its roll!
Circuit: Lightstorm
Some of you may have found the LightStorm Pummers that Mark Tilden has made using some neat looking plastics. We've built our own variation of the circuit, which is a dark-activated, quad-bicore pseudo-random chaos generated, dual pummer circuit.
Solarbotics has been operating for more than 25 years, bringing electronics know-how and supplies to both the electronics professional and hobbyist. We'll be happy to help you too!
