Measurement & Readout Electronics
This is an ongoing project, there are many modules I have yet to add to this website.
The readout electronics are for various topics in my interest, such as for single photon counting and Scintillation.

HDL implementation of processors
Hardware Description Language implementations of various old 60’s, 70’s and 80’s computers and processors that I have written over time. Mostly as an exercise but also for fun.
