Avalanche pulse generator, and some scope porn.

Saturday, July 20th, 2013

By now we are all sure you know about Jim Williams' avalanche pulse generator from his famous application note 47 we even posted about Kerry Wong's pulse generator using jellybean transistors. And we can't forget The EEVblog covering a build sent to him. Today we will be exploring our build, that is...

Avalanche pulse generator build using 2N3904

Wednesday, June 26th, 2013

Kerry Wong documented his avalanche pulse generator build using 2N3904: The majority of avalanche pulse generators hobbyists built used 2N2369, the same transistor used in Jim Williams’ original experiment. One of the main benefits of using 2N2369 is that it can avalanche at a relatively low voltage (under 90V). But...
