1.0 INTRODUCTION I decided to build and design a midi controller which is used to send commands to a computer running a DAW(digital audio workstation) to control different parameters within it. The DAW I used is called Ableton Live. There are 16 button pads and 6 potentiometers on the front of the unit. Depending on […]

The Micromite Companion Minicomputer is the next generation in the Pocket Mini Computer series. It is the combination of two Open Source systems, the Micromite software, a PIC32 creation by Geoff Graham, and the Parallax Propeller, a recently “Open Sourced” chip by Chip Gracey. By combining this two very unique chips we can create a

In this instructable I’m going to show you how to convert an old ATX power supply to a bench power supply that also displays the current drawn for each voltage rail on an LCD display. Features: The PSU uses a 20×4 LCD display to show the current readings for every voltage rail. But because the

One of my circuits that I build quite often (20 – 40 at a time), uses a PIC 12F675. I had the following issues: The boards that I make, does not have in-circuit programming capabilities. This is to allow for a small PC board layout. PICs thus need to be programmed out of circuit. I

On the first part of this instructable, I demonstrated how to program a PIC12F1822 using MPLAB IDE and XC8 compiler, to send a simple string wirelessly using cheap TX/RX 433MHz modules. The receiver module was connected via a USB to UART TTL cable adapter to a PC, and the data received were displayed on RealTerm.

If you don’t have a reverse backup radar system in your car, or if you park forward in your garage, you probably know this feeling of “am I too close, am I gonna hit the wall??”. There are a lot of ways to resolve this issue, but if you like tinkering with electronics and writing

Brief Introduction Smart home is becoming more and more common with the development of technology, this article will focus on the security aspects of the intelligent access control project. This article uses STONE’s touch screen to send commands to the MCU to control the relay and MFRC522 module. The principle of card reading: by driving

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
