Die Bloodsuckers – Pew Pew

In a bid to combat malaria, Intellectual Ventures is developing a method of killing mosquitoes with lasers. The system is called a Photonic Fence and identifies the beasties by the frequency of their wing flapping (hey, that’s exactly how we know when they’re dive-bombing our heads). Once locked-on, it’s death to the filthy blood-suckers.

This story was latched onto by the gambit of news sources in the middle of 2009. Since then, the development team has added some pretty interesting info on their webpage. Last Feburary several videos of mosquito flight were posted. These were shot at 6000 fps using specially designed photographic rigs (probably much like this one) to make sure the shots were in focus. Now they’re slated to give a talk at the 2010 TED conference. The publication of these talks sometimes lags behind by several months so be patient. Watch the video after the break to get some abstract shots of the hardware being used; they’re not giving up the goods until the conference.

XBMC Hiding In An SNES Controller

Here’s another SNES controller converted to house a USB system. The one we saw last time used a kit as an adapter for the controller but this version uses a home-built PCB and an ATmega8 microcontroller with the latest revision of an open source adapter for NES and SNES controllers. As you can see after the break, [Atarity] built the adapter, then added it along with a USB hub and thumb drive so that he could run a copy of XBMC from the controller. Now he’s got XBMC as a way to launch emulators for those classic games, as well as play traditional media.

You will be seeing more of this type of mod soon. We were tipped off that an in-depth tutorial for SNES controller hacking is on its way, although that is unrelated to [Atarity’s] work.

All Terrain Roomba

This little rover gets around on rough terrain pretty well. [Dean Segovis] built it using parts from a Roomba. The Roomba uses wheels in conjunction with gearboxes that handle a lot of the dirty work in getting this prototype going. [Dean] grabbed four of them, as well as the motor controller board and batter, and installed them on this Rocker-bogie suspension. In the video after the break he mentions that this would be quite a good climber if the batter were relocated to the center of the body. An ultrasonic sensor adds obstacle avoidance with and Arduino taking care of the processing. We can’t wait to see future versions of the Roomba’s rough-and-tumble outdoor cousin.

Massive No-touch Physically-interfaced Display

[youtube=http://www.youtube.com/watch?v=8bHWuvzBtJo]

[Daniel] wrote in to show us the project his group has been working on. It is a massive display wall consisting of 28 projectors and 30 computers.  With a resolution of 7168×3072, viewing a 13.3 gigapixel image is a treat. That treat is made even stronger by the fact that navigating the image is done multitouch style with a touchless system built from web cams.  We’ve seen lots of projects come out of the NUI group with similar interfaces, but none that used the webcams like this. Usually, the webcam is detecting some kind of interaction between the person and an infra red light source. Maybe that is happening here and we just don’t see it.

1-Wire LAN With An LCD

[Viktor], one of our favorite avid hackers, has been playing around with 1-wire systems all this month. What started out as a MicroLAN Fonera has turned into an iButton interface, to a 1-wire powered hub, and finally a 1-wire character driven LCD. Anyone looking at 1-wire systems or OWFS could surely benefit from his testing.

However, if you still haven’t gotten your fill of 1-wire goodness, let us remind you of the 1-wire HVAC and IPv6 to 1-wire protocol translator.

PC Cooling Using 1000 Ft^2 Geothermal

Are you still using heat sinks and fans to cool your computer? Lame. Tearing up your property to bury geothermal coils is definitely the way to go. [Romir] has been working on this for about a month and is just getting back data from the first multi-day tests. Take some time to dig through his original post. It includes something of a table-of-contents for the 35 updates he’s posted so far. Closed loop cooling seems to be trendy right now, we just didn’t expect to see a system this large as part of a personal project. The last one we looked at used just six meters of pipe.

Snega2usb Changes Name, Learns New Tricks

[Matthias Hullin], the creator of the snega2usb let us know that its name has been changed to the Retrode. We watched this device go through the development cycle and learn to read SNES and Sega Genesis cartridges via a USB connection. Now it’s seeing some hacking to extend those capabilities. [Jon] managed to rig the Retrode up to read Virtual Boy cartridges. The Virtual Boy was a Nintendo console from the mid ’90s that used two different screens in a glasses format to produce a 3D gaming experience. Now that the cartridges can be easily dumped you have a chance to replay the titles using an emulator.
