The prize this week is a solar flashlight, if you want to use this as a flashlight you better charge it during the day and not keep it hidden in a drawer. 🙂 I am thinking that the housing could make for a very small surface mount project. Not sure if the solar cell would have enough power to energize a very low current circuit but I would think it
We have seen a few Rotating POV Globe in the past. Scitech has a Arduino based Rotating POV Globe which looks quite nice, the refresh rate of the camera screws up the effect a bit but I assume it looks perfect in real life. “The Rotating POV Globe utilizes the arduino uno as the central control brain which contains an Atmel AVR microcontroller. Essentially we have a rotating ring which
You might remember the Timing Chain Clock that was featured earlier this month. Steve Moseley left a comment letting us know that there is actually one similar to what I was saying would be cool to see. I was thinking that it would be great to have the Timing Chain Clock have three gears and chains so it could show hours and minutes. Well Youtube user Mosignose actually has built
When you squint a bit and loose scale these mandarin oranges look a bit like small pumpkins. I wanted to rev up the Halloween spirit around the house and without a real pumpkin to carve I settled for the next best thing. That is of course a laser etched pumpkin carving onto a mini orange which is lit from the inside using an LED. I wasn’t sure how it would
Youtube user misperry has been making a ton of electronic tutorial videos. These three videos go over how to use the capacitive touch modules that are built into many PIC microcontrollers. These videos go over how to design a circuit using the 16F727 microcontroller which has M-Touch, this is what Microchip calls the capacitive sense modules.
The MD-80 Mini DV Spy Camera is a great low cost camera, don’t expect it to be a replacement for your HD camcorder which cost you a 5 hundred bucks though since it can be found in many places for less than $20. Considering the price you get a ton of technology packed in a small device. The first thing I noticed with mine is that it has a time
If you want to wear a set of glasses that will make you look like a cartoon character look no further than Blinking and Winking Laser Cut Eye Project. They can wink, blink and if you shine a bright light at them they will squint. If you are interested in making one for yourself Ben has made the Arduino code available here.
