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 […]
New Product!

We've been shopping again, but the accountant won't let us hoard all the goodies for ourselves. SOOO, we're announcing the following goodies!
- RBFB: The Book "Robot Building for Beginners" by David Cook, which is an excellent reference for a newcomer to robotics. It's an ideal companion for our own book "Junkbots, Bugbots, and Bots on Wheels".
- SWT8: A new tiny micro SPST switch that is simply too tiny and cool not to take a look at!
- SWT9:A new small lever action SPDT switch with solderable lever. We're doing many experiments using these as robot tactile sensors.
- CdS: There's been renewed interest in photo-resistors (or photocells, or Cadmium-Sulphide cells), and we've finally found a source of good quality units. Unlike many surplus CdS sensors we've tested in the past, these are in reasonably good tolerance.
- 0.01µF Capacitors: It's easier to do high-frequency Bicore experiments with a small capacitor!
Well, back to work - must find more things to hide from the accountant!
