AVR Mega8 RSS Reader

avr_rss

[Barney_1] built this sereial RSS reader. He’s using the Dragon Rider 500 development board, which is a kit that has expansions available including the LCD, serial interface, and power supply. You don’t need the kit though, you could just build your own with similar specs. He has written a program in python to scrape RSS feeds and send them to the LCD. He’s got some specific workarounds for the Dragon Rider board if you do have one. You can download the firmware and source code on his site.  You can see a video of it after the break.

LCD Repair

lcd

[Andrew] sent us this great breakdown of an LCD monitor repair. After his wife’s monitor developed an issue with rippling in the picture, he was forced to decide between trashing it, or fixing it. He decided for the latter, possibly to his wife’s disappointment. The rippling image could easily be attributed to a failed filter in the power supply. Knowing that capacitors are a prime suspect in these cases, he tore in, looking for failures. He found that there were, in fact, 2 bad capacitors on the back light circuit. After replacing them with newer, higher quality ones, the monitor was as good as new.

Rear Projection TV Multitouch

[Dave] sent us these fantastic instructions on how to hack a rear projection tv to be a multitouch interface. They’ve converted a 67″ inch TV by adding a couple of PS3 eye cameras and an infrared laser plane. There’s lots of great information, like how to replace the lenses on the PS3 eye cameras and how to create the custom fittings needed to make it all fit nicely. You can download the code, but it is Mac only.  They claim that this is the first conversion of a commercial rear projection TV to multitouch, but we know better. You can see a video of it in action after the break.

[Pedram] Sent us his USB missile launcher interface project. He happened to have some of the USB missile launchers lying around. having lost their initial draw, he wanted to do something to spice it up. He wrote an interface in python so he could control the launcher via his iPhone. We don’t see how this is any different than controlling them by the computer, but he seems to have put a decent amount of work into it.

Impress: Tactile Interface

impress

Touch screen interfaces are generally hard and flat. Impress tries to break from that tradition by making the display flexible. Allowing you to feel more like you are interacting with the display. In the image above, the circles seem to physically fall into the dent made by your fingers. Another application shows some rudimentary 3d modeling being done by physically pushing on the vertexes. This prototype is very interesting, we’d love to see much higher resolution on the input side of things. It states that it does pressure sensitivity, but we weren’t able to distinguish it in the video. Maybe you can, catch the video after the break. Maybe laying one of these on some foam would be another alternative.

Build A Wiremap

wiremap

For those of you who don’t recall, the Wiremap is a 3d volumetric display built from hundreds of tiny strands. An image is projected onto the strands to achieve 3d effects. [phedhex] has posted an in depth instructable on how to build a wiremap. He covers the construction with lots of good tips as well as giving links to the software for Windows, Mac, and Linux. Check out the video after te break to see some fairly impressive 3d patterns.
