Laboratory Diary – A Transistor-Based NE555 as a Test for Giux-CalcLab

Written by giux | Published on Sep 3, 2026 | No comments

A circuit inspired by the NE555, built entirely with transistors, resistors, capacitors, and diodes, becomes a test bench for the SPICE simulator I am developing on my server.
