Here is another great instructable project brought to you by nodcah, a DIY Fingerprint Scanning Garage Door Opener. Tired of constantly being locked out of his home because he doesn’t always carry any keys on him he decided it’s time to get creative and build an automated door opener using a 3D printer and some parts he bought online which includes a serial LCD kit sold by Sparkfun and a ATmega328.
In my previous post “What Is A Raspberry Pi” you would have noticed that there are many uses for Pi and in this post I am going to show you how a guy by the name of Bob Clagett created his very own retro arcade machine using a Raspberry Pi. This article will hopefully give you some ideas and inspire you to make you own arcade machine with parts laying around at
Now here is a great idea, why not replace your old Fluorescent tube lights with LED ones and save on electricity. This is a simple DIY hack which can easily be done using an LED strip light and a AC to DC transformer. Now there are LED tubes available you could simply just plug in and you good to go but that takes all the fun out of it and besides

Credits to mikelllc This project describes the design of a very low budget 3D Printer that is mainly built out of recycled electronic components. The result is a small format printer for less than 100$. First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a small
Similar to the Radio Microphone, in this post I will show you how to build your very own radio transmitter by replacing the Microphone with a 3.5mm headphone jack. This can be used as a Radio MP3 player for your car, simply plug your phone into the 3.5mm headphone jack then tune your car radio into the same frequency as the modulator and what ever is playing on your phone
Radio microphones are used extensively by stage performers and professional eavesdroppers (Spies) but they can also be used for other fun projects such as monitoring of sounds. For example you can take an ordinary household portable radio and tune it to your desired FM frequency, then tune the microphone to the same frequency and place the microphone in a location around the home such as in your new born baby’s
