JALPIC One Development Board

JALPIC One Development Board

If you follow my Instructables projects you know that I am a big fan of the JAL programming language in combination with the PIC Microcontroller. JAL is a Pascal like programming language developed for the 8-bit PIC microcontrollers of Microchip. Most people know the Arduino using the ATMEL microcontroller. One of the nice things of […]

Digital Controlled Linear Power Supply

Digital Controlled Linear Power Supply

In myteenage years, about 40 years ago, I created a dual linear power supply. I got the schematic diagram from a magazine called ‘Elektuur’, nowadays called ‘Elektor’ in The Netherlands. This power supply used one potentiometer for the voltage adjustment and one for the current adjustment. After many years these potentiometers did not function correctly

Cat Repellent

Cat Repellent

To start with, I do not hate cats but I love birds. In my garden we have some open cages where birds can enter and leave as they please. They can find food and water there. Unfortunately sometimes a cat from the neighborhood enters my garden and I do not want it to catch any

VFD Display for the TI83 Calculator

VFD Display for the TI83+ Calculator

This project builds upon the PIC/TI83+ interface developed by ThomasHenry (see Nuts & Volts August 2013 – A Mathematics Engine for Microcontrollers). Acknowledgment, appreciation, and kudos to him for writing the TI-library for Great Cow Basic that made this project possible. When I recently re-discovered that article, I imagined re-creating the only calculator that was

Illuminated Cubes

Illuminated Cubes

This project is a follow up of the Illuminated Presents project that I posted earlier. My wife really liked the Illuminated Presents but kept them as Cubes and did not put a bow around it to turn them into presents. Because of this success I created a second one – called Illuminate Cubes since that is what

Model Train Speedometer

Model Train Speedometer

This project started off being based on an Arduino UNO. And it worded ok, I found the software published on the internet. For example https://forum.arduino.cc/t/model-railroad-speedome… But I wanted to make the device smaller, neater and if possible to improve the software. With this version you can program difference GUAGE (OO, HO, O, N, Z) using a
