TTL triggered stimulus generator

Thursday, August 3rd, 2017

Scott Harden has a nice build log on his TTL triggered stimulus generator project: I was presented with a need to rapidly develop a pulse generator to take a TTL input and output a programmable output (for now 0.1 ms pulses at 20 Hz for as long as the input...

Avalanche pulse generator- part 2

Thursday, September 11th, 2014

 ssihla has been working on a pulse generator project. He writes: I build a more permanent version of the pulse generator with some changes. The comparator wasn’t working very well with the 1V reference I was using. I made some measurements with different voltage references and got this

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...
