In this tutorial, I will show you how to write a very simple program. I am assuming that you have written ladder logic before, and that you have some basic familiarity with microcontrollers, but that you have never used LDmicro. If you don’t know very much about ladder logic or PLCs, then the plcs.net tutorial […]

Since I started my watercooling prejoect, I have been verry interested in how well it perform, the only way is to measure all temperatures before and after, The motherboard temperature sensors is useless unacurate, so I’m using LM50B By using this LM50B sensor I get 1 C of real accuracy I use a PIC16F876 to […]

Given how important chips are to modern society EVERYONE should understand and appreciate how they are made.  Every field has its own set of terms, jargon, and acronyms (engineers love acronyms!). As you would expect, chip design is no different. If you are new to chip design, it might take you a few days to read through the Wikipedia […]

Description This is a versatile, configurable, and cost effective Development Board designed for the 18F – 28 pin series of Microcontroller from Microchip. The board is simplest form with all the Port pins terminating in a header connector for easy connection to the outside world.

Heavy duty portable charger for usb devices (phones, iPad, etc.) Ever needed to charge your phone on the go? Can’t find a wall socket to charge your iPod? Whenever I’m away from home for an extended period of time, I would charge my phone and mp3 player from my laptop.  This way, I get about 3 […]

Introduction The objectives of the FailureBot project originated simply as “build a line-following robot”. However, it somehow evolved into a 3-year robotics experiment. My first attempt to build a robot was such a complete failure that I jokingly called it “FailureBot”. The name seemed quite appropriate even as the project evolved as every one of […]

Description Power Pic RGB is a circuit that generates random RGB colors using a powerful 3W RGB LED and fades between them. The initial project goal was to develop the fading algorithm which was successfully achieved. This time the idea was to drive a Prolight 3 Watt RGB LED and place it inside a nice […]

When S/PDIF became available in the Teensy Audio Library I thought this might be the solution to ground loop problems I’d been having when interfacing projects to my PC. However, I quickly realized I didn’t have any sound cards with an S/PDIF interface. In the belief that I’d rather build than buy I decided to […]

This project is an open source 3.2″ Smart TFT display board. The board is based on a PIC32 and a 3.2′ TFT with touchscreen (ILI9320 controller, using 16bits PMP). The software has two main parts. One that produces the 2D functions and a GUI with various widgets (buttons, check boxes, sliders etc). Description A new […]

Abstract: USB has just become easy to implement. This application note eases equipment designers into USB by allowing them to continue to transmit and receive data using the familiar UART frames of the MAX3100 UART. A UART-to-USB converter IC and operating system driver will take care of all of the USB complexity. The application note describes […]
