Just roll the foil flat with a rolling-pin, use thin wire to minimize the air that will be trapped between the dielectric layers, and make sure the foil plates are at least 4cm shorter than the acetate film on each end to prevent leakage. He stuck with aluminum foil for the two plates. This is the material from which overhead transparency sheets are made. He thought the paper and foil capacitor project was a nice introduction to the concepts, but at the same time he knew he could produce a much more powerful device.įor the dielectric he is using acetate film. tipped us off about his method for building your own high-voltage capacitors. Posted in Peripherals Hacks, Video Hacks Tagged LCD projector, overhead projector, video projector Roll Your Own Capacitors – High Voltage Edition We’re loving the result and are sure it will be much appreciated at ’s LAN parties. If you don’t count the few LCDs burned through while building his project, his projector was built for under $100. started off looking at the LumenLab DIY projector project, but considered that to be a terrible amount of work with a fairly high initial investment. The bulb in the projector added a lot of heat, so three small fans are used to blow air between the projector glass and the LCD display. started his project by picking up a surplus overhead projector for $25 and routing a cutting board to mount the LCD in. The basic idea is fairly simple, but we’ve never seen anything that could be considered a semi-permanent build. ![]() Using a bare LCD panel with an overhead projector is a decades-old hack we’ve covered before. wanted a huge-screen TV on the cheap, so he converted an overhead projector to something he can use with his XBox. Hence the need for clear transparency paper.Īnd wisegeek, great job on mentioning how to print on transparency paper - you have no idea how many gummy messes I've pulled out of my printer because somebody didn't use the inkjet transparency paper.Apparently, there’s some sort of sporting event being televised this weekend that has been historically used as an excuse to buy a big-screen TV. The whole point in using transparent paper is so the overhead lamp can shine through it. ![]() September 9, - I don't think so, not unless it was really thin. Of course, I bet it's also a lot more expensive than normal ink jet transparency printer paper. I've heard that they've even made laser printer transparency paper now - I bet that makes for some cool graphics. Could I just get transparency film instead? I have a school supply list that asks for: "3m transparency paper, 11x17". Is there a difference between transparency film and paper? Other laser print transparencies also bow, do you recommend any brand that will not have this problem?Ĭan you paint kids' washable paints onto transparent paper, and will it dry and stay on! thanks for any feedback. This has now been discontinued by my supplier and I cannot find it anymore. I used to get transparent paper that was thick and did not warp. I've printed onto transparency paper and its not drying.
