[Jacob] wrote us to show off his latest project. He built his multitouch interface out of an LCD monitor. We’ve seen plenty of multitouch projects here, but usually they are projection style. This project uses the panel out of an LCD, with the diffusers and backlighting removed. The panel itself is fairly transparent, so a webcam with IR filter can see the light pens right through it. It does seem a bit dim in the video, we’re wondering if it is better in real life.
The newly released Palm Pre has been torn down by both Rapid Repair and iFixit. They note the easy to use interface, but the slide out keyboard makes for weird transitions. There’s nothing surprising on the hardware side except capacitive screen and LCD come as a single unit and would have to be replaced together if either fails.
[Roland] recently graduated from UC Berkely. For his graduation ceremony, he wanted to do something unique. He built a diorama on his graduation cap depicting a house driven from alternative energy. The whole thing is solar powered. The wind turbine is actually powered from the solar panel, and with a remote control, he can make the sun rise and set.
[Raguaviva] shows us in this video how he’s using an optical mouse as a low quality camera for his DS. This seems like a pretty cool hack, but we’re at a loss to think of a good use for it. As he gets to the end of the video, he seems to also have trouble thinking of a good use for it. Do you guys have any ideas?
[Folklord36] on the Acidmods.com forums has been working on a PSP laptop that we think gives the PSP GO a run for it’s money. Sure it may be a bit bulkier but it has a full keyboard, thanks to an Xbox chat pad. The original psp is on the bottom. The screen and speakers have been moved to the top. He says there are still a lot of things that need to be finished, but this is pretty impressive already.
The new Palm Pre cellphone has a “media sync” feature which lets the device sync with iTunes in a fashion identical to an iPod. Last week [Jon Lech Johansen] speculated that this was not done in cooperation with Apple and that Palm was spoofing the iPod’s USB controller. This was confirmed today when a tipster sent him a screenshot of what the device reports in both standard and media sync modes. The Palm Pre reports its Product ID as iPod and Vendor ID as Apple with a few other changes. [Jon] notes that it doesn’t change the root USB node, so Apple should be able to block this behavior with an iTunes update. With Palm already pulling tricks like this presumably through software we wonder if this will become a full-on arms race.
When an unsuspecting person walks up to [Rob Ray's] ATM machine, they are greeted with a surprise that doesn’t involve giving them their money. When they insert their card, the video above plays followed by a game where you control a beaver trying to save money during a recession. Surprisingly, people usually found it humorous and didn’t immediately freak out that their card was in a machine that wasn’t their ATM. His site has all kinds of pictures of various users as well as the construction of the project.
[Alex] sent us this project he’s working on where he’s building a phototransistor based multitouch input system. Though many people have built systems with phototransistors, most of them are quite large and very sensitive light and dark variances. [Alex] has done some fancy background subtraction through software. He believes his is the first to do this. As you can see in the video after the break, it seems impervious to the lamp he is moving around, and still fairly sensitive to his hand. We’re curious to see where he takes this one.
