This is a simple design that demonstrates the USB peripheral on the PIC 18Fs. There are a bunch of examples for the 18F4550 40 pin chips online, this design demonstrates the smaller 18F2550 28 pin version. The PCB uses surface mount parts, but all components are available in through hole versions. Source: ian

Certain buttons on a TV remote can get worn out over time. In my case it was the channel up and channel down buttons. The contacts on the bottom of the button are likely worn out. This is how I fixed mine. Source: mmelville3

Monitoring several cameras on one monitor is usually done in one of two ways:  divide the screen into sections and show them all at once, or time sequence the cameras onto the whole screen. Source: Mondo

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 [...]

Devices known as electrical key-lock can de found in many versions,specificity of that device is a new way to read more keys using only one input of microcontroller. More information about KeyLock you can find in magazine “Svijet elektronike”, nr. 51, April/May 2005. Source: Ivica Novakovic

This is one of the most simplest LC inductance / capacitance Meters that one can find, yet one that you can easily build yourself. Source: SQ8CBY

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 [...]

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 [...]
