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!

Weekend tidbits
Dave Hrynkiw
February 20, 2009
Greetings my fellow humans! And salutations to my not-so-fellow alien amigo! There are a few small tidbits of news this weekend:
First, we received our shipment of new Herbie PCBs! Hurray! This means that you can now get Herbie the Mousebot in all four colours - red, black, blue or white. They're all in stock, so get as many mice of many colours as your heart desires. Or as many as your cat will let you get away with.
Next up, we now have white-ish, grey-ish servo wheels. You've probably seen them in the item's image for the past while, but now they can be ordered at any time. And just think - this means we almost have the same colours for mice as we do servo wheels. But who ever heard of a yellow mouse? Red or blue rodents are one thing, but yellow? That's just crazy.
Our last and not-so-exciting news piece for this evening is that the latter half of our category organizing is taking effect. You'll now find that our motor drivers and Sumovore/ScoutWalker brainboards and addons are in the Microcontrollers and Brainboards and Addons categories respectively. If you have any questions or can't quite find what you're looking for, feel free to give us a shout.
Have a great weekend everyone!

New Product, Closed for Good Friday
Fun fact: Tomorrow is Good Friday. By default, that means for the other 51 weeks of the year we experience Bad Fridays. We're not quite sure what exactly makes them so undesirable per se, but because the chance to celebrate a Good Friday comes around so infrequently, we've got to act on it, dangit. So […]
Circuit: L293D Mini-Sumo
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.
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!
