Check out RMCybernetics for instructions on taking these wild pictures. “A kirlian photo is a photograph of electrical corona produced around objects under the influence of high voltages. There are two common methods for producing kirlian photos. One is a little tricky, but the other method is quite simple if you have access to a few basic bits of equipment. You can see how to make a high voltage power
After reviewing the Forever Flashlight for The Gadget Panel I couldn’t help but take its capabilities to the next level. I wanted a portable USB charger that could recharge things like my iPod Shuffle. I know there are lots of battery powered options, but I wanted something that didn’t need battery replacement. USB power is 5 Volts and that is exactly what this flashlight puts out on the auxiliary power
What can make a sweet high end car stereo even better? Some custom electronics to relocate the USB interface will do the trick. “Some friends buy me a nice MP3 player for my car last year. This stuff looks great and you can even plug a hard-drive. The main issue is that the firmware only support 999 files on a single USB device, so that’s enougth for ~4Go of MP3
A Van de Graaff generator is a simple way of producing high voltage. There are many DIY generators that can be made with some everyday items. Here is a link to some additional information. Video after the jump. “A Van de Graaff generator is an electrostatic machine which uses a moving belt to accumulate very high voltages on a hollow metal globe. The potential differences achieved in modern Van de
Click To Play Last week we introduced you to the High Altitude Balloon experiment. The project is getting closer to completion, watch the video to see the progress. “Make: is going to space.Have you ever wanted to go up into space? Well, you don’t have to try and win a golden ticket, be a millionaire, or an astronaut… you can send your own payload into space! In this Make:
Raphael Assenat has designed a circuit that allows a computer parallel port to control 110VAC lighting. It is optically isolated allowing the computer to remain safe as it switches the high voltage. “I had been thinking of controlling my room lighting using my computer. I bought some triacs and opto couplers to do this. I drew the schematic and built a prototype. Everything worked well. When I was wondering in
Dick Cappels has made a DIY LC meter. As usual he has provided full schematics and code so you can build your own. “There must be half a dozen similar LC meters on the web. Why didn’t I just download one of them and use it? I suppose part of the answer is that I wanted to do some of it myself. As nice as these other projects are, I
