| | | | | [AI summary] The user is building a custom instrument that combines a current source/sink with measurement capabilities. They designed a front panel with cutouts for a display, buttons, and jacks, and used an aluminum PCB for the front panel with solder mask for silkscreen. They also designed a mounting flange for the front panel and a rear panel with cutouts for a fan and USB-C connector. The instrument uses an Arduino-based MCU for control and measurement, and includes a detailed mechanical and electrical design. The user is seeking feedback or comments on their project. | |

| | | This project is a little old, but now that I have some time, I thought it would be nice to write it up! The device has been serving me well for a few years now. Being somewhat red/green color blind, I've always had trouble reading through-hole resistor color codes (though I often wonder if those with full color vision have it much easier - some resistor bands are so 'muddy'!) I make do with labeled pouches holding my resistors, and a multimeter to double-check. The multimeter is so slow. Surely it shouldn't take seconds to sense a resistor value! For years I dreamt of making a faster resistor measuring device with an instant readout. The 'final straw' that pushed me to actually do that was that I bought a beautiful old metal Akro-Mils cabinet1 stuffed with o... | ||
