This is a new section (2019) and it will contain various projects I make, this will often be test equipment of some type, but can also be useful Arduino libraries, some notes or something I make just for fun. Some of the projects will include everything to duplicate them (Software, schematic, PCB layout, gerber files, manual, etc.), other will just show what I made, but without detailed information. I do not expect to post new projects very often.
Display driver library for 7 segment LED and LCD displays on Arduino
This is a "library" that basically supports all the cheap serial 7 segments display found on Ebay, both display, indicators and keys.
Computer controlled logic outputs
This is a 3.3/5V driver can be controlled from a computer to turn on/off, do PWM or pulses of various types, including LED control (NeoPixel). The project includes full schematic, software, manual, etc.
Computer controlled solid state relay
This is 3 isolated mosfet transistors that can be controlled from a computer to turn on/off, do PWM or pulses of various types. The project includes full schematic, software, manual, etc.
Building a high current adapter
This is a fairly old project I have moved from "Anything else" to here. It is a very low voltage drop current "shunt".
