Now that the season of mass gift giving is (temporarily) over, publishing the details on this special gift for a wedding anniversary will not ruin a surprise. So I figured I'd share this personal project that uses simple but smart electronics.
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 robust P-Channel FET that is capable of interfacing with most 5V-logic microcontrollers. |
|
NDP6020P P-Channel FET, --2.5V gate, -20V, 24A max $1.95 An N-channel FET with an extremely low gate voltage which can be controlled by most 3.3V and 5V microcontrollers. |
..and no, these are not even Forcibly Eccentric Tabbies.

It's snowing here. Here's the proof - a ruler measured with another ruler, reading about 7" depth of (what used to be) snow. It's a massive invasion of snowflakes, and they don't seem too friendly. The amount of snowfall we are experiencing now can prevent anyone in their right mind from being outside. And the […]
Wireless doorbells have a tendency to... suck. I speak from personal experience on such matters. When they fail to get my attention while at home, apathy generally wins out and inevitably forces me to head down to the FedEx/UPS depot to pick up my missed package. David Watson, a man of action, took matters into […]
The whole 'duino thing is just so much to say, we've got to do it three times. Blame Jerome, our intern... We've got Freeduino version 2.2 back from the assembly line today, and all tests out beeeautifully! New features include an SMD-mounted 16MHz crystal, better power-consumption circuit routing (for battery-operated projects), and "hacking pads" for […]
