Projects

DSC_7183

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.



7 & 14 segment display modules specifications
DSC_7805

This is a list with measurement of all the 7 & 14 segment displays I have used to make my library. It is sortable and contains filters.


ADS1115 ADC library
DSC_8619

This library allows use of any speed and gain of the ADS1115 while running it in the background. It can also do auto ranging conversion.


Display driver library for 7 segment LED and LCD displays on Arduino
DSC_7805

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
DSC_7523

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
DSC_5462

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
DSC_1310

This is a fairly old project I have moved from "Anything else" to here. It is a very low voltage drop current "shunt".
