How did you do the sinewave animations on the speed of light in a microwave article? They are neat.

I have constructed several SDR SoftRock kits this way, works like a champ, not one component failure.

I soldered a DDS daughter card with the skillet, had a few bridges, no sweat – solder wick took care of that.

I would like to use the toaster oven though but need to find thermostat controller circuit board and micro-controller info.

Unfortunately, there has been a small issue with the site lately. I did not realize that Ruby 1.8.4 is required for Typo 4.0! Luckily nobody noticed anything unless you tried to post a comment and it never appeared.

i am doing this doorknob touch alarm as our school project…but i am having a problem with it after transferred the component to matrix board…we used 9V as a supply voltage…that c2 is it 0.0047F or 0.0047uF?..the problem is that the alarm triggered continously…we set the potentiometer to 12.9kohms already for the sensitivity but still it keeps on triggering…i need help asap =(

You can use BS107 instead of ZVNL110A.
The circuit works very good with this
MOSFET.
