Not much to type here, but I completely redesigned my constant current circuit. I replaced the current sense amplifier with a programmable gain amplifier, added an ATMEGA328P microcontroller, a pinout for an LCD screen, a pinout for I2C and ICSP,
Mini Circuit 1: Constant Current Sink
I’m starting a new project series, I am going to call it Mini Circuits! Basically my idea is to make some circuits for some pretty common situations I have come across at work, and make a dozen or so. They
