Computer Hacks

Solar Hot Water Heater

  I wasn’t aware that central hot water was rare in Brazil, here in Canada every home has central hot water and it is just taken for granted that every house has a large electric or gas heated hot water tank. Jacob Teater wanted to cut his electrical bill by installing a Solar Hot Water Heater and re-plumbing his home. Have a look at the video around the 8:40 mark

CD-ROM Door Lock

  This is an interesting project that uses an old CD-ROM drive to make a CD-ROM Door Lock. Granted the system isn’t very secure however it would be trivial to connect it to a real deadbolt. It sounds like the system is voice activated but it is just the inventor asking his son to control the system while it was being recorded. "The circuit board in the middle is an

Hack a Sketch - Computer based Etch a Sketch

  The guys over at the Project Lab have made a cool Computer based Etch a Sketch project called Hack a Sketch. Looks like it works just like a real one. This project is basically the reverse of this Etch a Sketch hack that we have seen before. Thanks for the tip Jack. "An Arduino board reads the inputs from two potentiometers (the knobs), and sends the information via USB

RFID Music Selection - RFiDJ

  Music selection is usually a boring process. It usually involves some common interface such as scrolling through titles on a portable player, using a remote for your stereo or a mouse on your computer. With this RFID Music Selection called the RFiDJ from Roteno Labs music is represented by tiles and the tiles graphically represent the music that can be expected. I can think of lots of opportunities for

Internet Connection Quality Monitoring

  Morten Bentsen, a 17 year old from Norway made a system that would show him the quality of his internet connection at a glance. If you are into online gaming this could be something useful. "I recently made an indicator to show the status of my internet connection. It consists of a small VB.net application, which pings a certain site with a set interval (both user-changeable, and sets the

iMac G4 Touch Screen

  Instead of purchasing a new iMac Dremmel Junkie opted to add some new features to his original iMac G4 such as a touch screen! "Because the monitor connects to its controller through a proprietary connector its difficult to use with upgraded equipment. My solution was to put a shelf on the back for the connectors. I then upgraded it with a surface acoustic wave touch screen, its high resolution

Voice Controlled LED Sign

  There are lots of Nerd Kits project examples available. Josh Davis used the LED Array Sign project and added a cool option for the sign to display voice messages left with the help of a Google voice to text service. Josh has documented the project here and has made the code available. Via: Make "On the software side of things, there are two python scripts that make everything happen.
