Kostas Kokoras built a Hacked Ericsson Cell Phone and Arduino Remote Control System. Kostas broke out the Ericsson T65 cell phone serial port to allow him to connect it to the Arduino, nice of the Ericsson engineers to give us a usable serial port that is easy to access! The system looks for specific phone numbers and a certain number of rings to perform functions, this is a great
 If you like the idea of having a GPS tracking device in your car to monitor the actual location of it there are some devices that you can simply purchase like the SilverCloud we saw before. But if you like to build things yourself have a look at the Realtime GPS Vehicle Tracking device that Sends Data using GSM by the guys over at Cooking Hacks. Not sure
 We all have thermostats in our houses but how often are they in a horrible place? You often want to place the temperature sensor in a different location than the control and display unit. There are lots of models that have remote sensor capability but they come with a high price. If you already have a thermostat and just need the temperature sensing to be disconnected from the
 Remember cassette tapes? These were small devices that held a spool of plastic covered in rust and allowed us to record audio onto, if you were brave you would even store your Commodore 64 programs onto them. This Cassette Tape with Hidden MP3 Player project looks just like a Cassette Tape but has a Hidden MP3 Player inside to allow you to hold a full case full of
If you are looking to add some WiFi connectivity to your next project the HLK-RM04 Serial to WiFi Module might be just the thing if you want to go wireless. The $10 HLK-RM04Â module handles all of the WiFi overhead so your microcontroller project can simply send serial data to it using the TX and RX pins. RAYSHOBBY.NET has a great tutorial including code to get you started with
Wanting to make an impact on the sidewalk quickly? This Spray Chalk Machine is sure to get that done. “This device is controlled by two Arduino Duemilanove boards, which apparently base the chalk “dot†timing on encoders sensing movement in the two wheels that the cart rides on. ”
 Check out this great Binary Wrist Watch. It’s a true watch for the geek since most won’t be able to read it! Via: Dangerous Prototypes “The time setting mode can be entered by holding the left button for two seconds. After that the display is blanked and the time can be set bit by bit by switching through the bits by pressing the left button. If the bit
