When you make MOSFET assemblies with especially when they are retrieved must be checked before assembly. This may seem very simple checker can check all N-type MOS-FET.

The TV-B-Gone is a neat little device that can turn almost any TV on or off. It uses a microcontroller hooked up to IR LEDs to output a library of on/off codes. Adafruit sells a kit, and has the code as well as the schematic on their website.
Here’s a micro clone of the TV-B-Gone that [...]

iCircuit is the premier iPad and iPhone app for designing and experimenting with circuits. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.
You use it as you would any CAD program: you add elements, connect them together, and [...]

This video will you show how to make a JDM2 PIC programmer and to learn  how to burn firmware on a PIC microcontroller in different ways.

The idea was to utilize a diffused RGB LED, an analog temperature sensor (really wanted to expand my working knowledge of the ADC on AVRs) and a frosted glass sphere to create a highly visible temperature indicator. I quickly sorted through my parts bins and found most of what I would need. A quick search [...]

The author of this project is Andrei Mehiläinen.This project is very simple thermometer with PIC16F88, two LM35 sensors and KS0108 graphic LCD.The code is written for CCS C compiler. There’s also Proteus VSM simulation file and compiled hex file.The Author also has completed a number of interesting projects, like: Project MapViewer, Audio spectrum analyzer, GPS [...]

This project is based on PIC 24HJ256GP206 processor and add a dash of knock-off touchscreen and a pinch of SD card compatibility for a DIY digital picture frame. [Daniel] wrote his own driver for the HX8347 controlled LCD that can achieve 15 FPS at 320×240 resolution with 16-bit color. As this was a gift for [...]

The goal of this tutorial is to teach you how to take a circuit drawn in a fabrication program like Altium or Eagle and make it a real-life PCB. To accomplish this we will need about $20-25 and a few hours of spare time.

The objective of this instructable is to show you how to add custom graphics to a PCB using EAGLE Layout Editor. You might want to add a logo or your website address to an electronics PCB that you have created. I found out that the process of adding images to a PCB was not trivial [...]

Some software developers don’t get into hardware because they enjoy the instant gratification of seeing their work displayed on screen.  They don’t want to fuss with soldering or hooking up components.  Now, however, they can’t complain since Virtual Breadboard can now simulate the Arduino software along with a library of common components.
