The idea for creating a USB sound card based on a PIC came from discussions of other people creating one on the Microchip USB forum. The hardware of the card is based on all Microchip products. The software uses a modified version of the Microchip USB framework which is interrupt driven instead of the traditional [...]

Almost all of you have seen or used an automated drinks maker, so I presume you have a rough idea on what is an automated drink maker. Please note that this project was my degree 2nd year group project , at Northumbria University. Even though the steps outlined below, will have sufficient information to build [...]

This is a simple how to make your own personalised LED Dot-Matrix display. I will be adding the complete program with an explaination to light the LEDs with. It’s also rather hackable, you can change it to suit yourself. Source: pinski1

This is a very simple IR light dimmer that you will wish to have sooner or later, especially those who are lazy enough to get up and turn off the lights. There are two versions of PCB for two sizes of capacitors: 32.5 x 26.5mm and 28.5 x 27mm. Dimmer is connected to existing home [...]

Quiz type game shows are increasingly becomig popular on television these days. This Indicator is powered by 12V.

This incredibly simple thermometer plugs on any free serial port. Does not make use of any programmable components as microcontrollers. It gives temperature readings accurate to 0.5°C with no calibration. It’s cheap, so I’ve put one on any PC I use. And it’s soooo nice to have the temperature shown on the Windows taskbar, that [...]
