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. Source: pyroelectro

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.

Mikroelektronika released a new Audio & Voice Accessory product called Audio Codec Board – PROTO. This tool features WM8731 Audio Codec and is intended for those who want to design and develop embedded applications which require audio playback. With popular price and ready-to-use examples, this board saves development time and represents an indispensable tool for [...]

The Crazy Looper is a small hand held device that allows you to create real-time noise loops with a fast modulation metallic effect. It’s a simple microcontroller project that I give an easy to build rating.   Source: rarebeasts

If you’re like me, you may or may not have secret files plotting world domination and other devious deeds. These files obviously need to be hidden from the prying eyes of sisters, FBI agents, grandparents, etc. We are going to convert a phone jack in the wall into a secret USB memory device.

This CNC milling machine that costs less than $100 (currently $87) to build. It can mill PCBs, wood, and even mild steel. All of the machine’s structure is MDO and is designed to be milled on the ShopBot. The leadscrews and leadscrew nuts require drilling and tapping operations that are preferrably perfomed on a lathe. [...]

This wireless hidden water gun is a real treat.Schematics and source code can be found at AVRFreaks but you must to be register.This video explain and shows the setup in action. The prankster holds onto a wireless AVR remote, and when the unsuspecting victim walks by, he activates a second AVR controlling a pump; spraying [...]
