If you have a spare Altoids tin this Handheld POV project might be a great way to fill it. You can make your own custom message with this page. “There are 32 message slots — 16 are straight hard coded bitmaps, 16 are text strings of any length. The text strings are mapped to ASCII character bitmaps with one extra trick — the engine will look for a break
Have a look at this fun project called the Shy Light. The light doesn’t like to be seen in public and uses a basket to hide in. X10 and two microcontrollers are being used to get the job done. “Why TWO Microcontrollers? The Dual-Microcontroller Circuit: Master (right) Slave (left) The Master Control microcontroller handles the foot-switch input, orchestrates the timing of the opening/closing of the basket (using commands to
 If you are a bike rider you might want to pimp your ride with some custom features. Have a look at what Jenna has done for some inspiration. She has provided all of the code so you can also duplicate her work.
I bet you thought your cell phone was the only thing with custom ringtones. Jason Poel Smith wrote in with his Doorbell with Custom Ringtones that he built using a Radio Shack Recording Module. “Most doorbells just make a simple generic tone. But I thought that it would be fun to modify a door bell so that it has a customizable ringtone. That way you can set it to play music
 Kelvin Doe who is also known as DJ Focus is a 15-Year-Old living in Sierra Leone. His community is not developed, for example the power only works one day a week. He has built an ton of electronic projects, the incredible thing is that since there is no Radio Shack handy he has to find his parts in trash cans. He also takes things apart to see how
What is the voltage on a AA battery? It would be around 1:30PM if you were using this voltmeter! A PICAXE 18M2 microcontroller is used to read an analog value, calculate what time it represents and then uses a stepper motor to spin the adjustment knob to have the clock show the voltage using the hour and minute hands. 🙂 Read more about the Analog Clock Voltmeter “The max
Thanks to David Powell from the Baltimore Hackerspace for sending in some details about the Lasershark which is a Laser Projector Project. It uses a LPC1343 – 32-bit ARM Cortex-M3 microcontroller to run the show, make sure you watch the video below to see this thing in action! “This board is intended to be a low cost open-source USB Showcard for folks who want to make their own 1
