Xmas coming and we need some new hardware. Xmas hardware has to be green + white + red + blinking. So PCB is green + white, then add some blinking LEDs and we are done. I have lot of “Right Angle Side View Red Clear Ultra bright SMD 0806 LEDs” (1206 work as well) , […]
The reason for making this clock was because my original IKEA clock did not work anymore and I really liked the housing of this clock. I found it a waste to throw the clock away and decided to re-use it for an analog / digital clock. I could have made a standard clock but I […]
I got to the result so it requires a bit more reading. At home we have quite some electronic tea lights, the ones from Philips that can be charged wirelessly. I have made an Instructable before related to this topic, see Tea Light Charge Monitorr. After some time these tea lights stop working because the rechargeable […]
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 […]
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 […]
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 […]
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 […]
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 […]
Brief Description: The main goal of this project is to design a DC motor controller, We had a DC motor controller that its control circuit has been damaged. Here we are attempting to design a new control circuit for the controller. But before we can design the control circuit, we needed to know the power […]
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 […]
