Take a look at this cool POV clock project that PyroElectro.com did. Please lots of other POV projects below, all of these projects are cool but the Pyro Electro POV Propeller Clock is probably the best documented one I have seen! It uses a PIC 18F252 Microcontroller to run the show and fan to spin the controller. IR light is used to keep track of where the spinning circuit board
The recently unemployed Dave Jones from the EEVblog has done a very extensive investigation of an issue he noticed which is the Noise an Oscilloscope Probe generates when Physically Shocked. I would have guessed it was just the switch that was not keeping a good contact when experiencing the jolt but watch the video to see what the culprit was. I remember having a similar (but totally different) thing happen
Just by adding a few wires you can use the BlinkM as a small Arduino. So next time you need a simple microcontroller that can be stuffed anywhere you might want to use a BlinkM. “The BlinkM board doesn’t have nearly the I/O pins and other features of a real Arduino board. But it is very tiny. Here are its capabilities: – 0.4″ square (MinM), or 0.6″ square (BlinkM) –
Looks like there is a new DIY PCB Etching Solution. If you have some Hydrogen Peroxide, Distilled White Vinegar and Salt you are ready to give it a try. Via: NBitWonder “Vinegar – Distilled White Vinegar – diluted with water to 5% acidity (Meijer) Peroxide – 3% solution (Meijer) Salt – to taste. (Just keep adding it until the “fizzing†continues all by itself). Hydrogen peroxide is what
The prize this week is a loupe magnifier, this will let you get a close look at whatever you are working on. This contest will run for one week (April 9Â – 15, 2011). Ending time is based on central standard time. To enter, identify the molecule pictured above. Please do not give the answer in the comments. Send an email to contest @ hackedgadgets.com with “Name the Thing Contest”
Check out this Huge Nixie Clock that Jaroslaw Lupinski built after being wowed by the Union Square clock. I also love clock projects since there is lots of interesting changes just by being a clock. Thanks for the tip Peter. “The timekeeping circuit is identical to my previous nixie clock: an Atmega168 controls the show, with a DS1307 keeping time. The only difference is that the sheer number of tubes
The guys from Sparkfun went on their second trip to China. They checked out some of their suppliers and lots of the markets. Via: Dangerous Prototypes “While there were shops and floors for all sorts of electronic goods, Bunnie had heard of a special market that dealt exclusively with bulk cell phones. That’s right, you could buy a pile of cell phones. Heck yes we needed to see this! This
