The guys over at Mondo Technology are at it again. If you have some PIC chips left over from your last project why not control a high voltage Marshmallow Bazooka ignition system with it. “This device uses a PIC12F629 to create a burst of 30 high voltage pulses. The PIC activates a 1000 volt N-Chan FET driving a standard ignition coil. After the ignition, the PIC goes dormant until activated
If you are in need of a CNC machine but don’t have the cash to buy one, why not make your own? Engadget has part 1 of an article explaining how to build your own CNC machine. “Computer controlled mills have been around for a long time. If you just want to buy oneone, Sherline makes mills that are ready to go (pictured is their CNC ready model — just
A mix of extreme high voltage and tunes, does a project get any better! Steve Conner has posted his ultra cool visual instrument on 4HV.ORG. Note the second video was listed by EastVoltResearch and can be seen on this site. “I finally gave in and decided to post footage of me testing my OMG super secret musical DRSSTC. I designed it last year as a paid commission for a Danish
The Handy is an interesting project by Zaizhuang Cheng, Derrick Ko, Colin Tan and Naga Setiawan from Purdue University. Very impressive since the parts cost is around $100.00. “The motivation is to provide a button-free environment in which the user can just use hand gestures to control the sound system. For example, when the user is driving, all he has to do is perform the appropriate hand gestures to
You have seen propeller clocks before, but what about a Nixie Propeller Clock? I didn’t think so! Check out the link for code and a schematic. “I stuffed the board with the PIC, the crystal oscillator, two logic chips, 10 HV transistors, the nixie, the HV inverter from a disposable camera flash circuit, the 7805 5V regulator, a 0.6 Farad memory cap, diodes, and the pushbuttons for setting the time.
If you have a Roomba, why not buy a broom and put the Roomba to better use. “The other day I was marveling at the efficient operation of my roomba when it occurred to me that it would be really nice if roomba would get me a beer. While gestating the idea my first thought was to have roomba follow a line to the fridge and back. And a
If you need to set a quite door bell period this is a cool (high tech) solution. Code and a detailed circuit explanation can be found at Richard Cappels site. “To set the timer, you just push the button momentarily, and when its released, the amber LED will come on and the doorbell circuit is disabled (the door bell button doesn’t work) for a 10 hour period. At the end
