Electric motorcycle rocks one wheel

We had to call it an electric motorcycle in the title because electric unicycle just sounds lame. But the video after the break shows you that this prototype is anything but lame. It takes minimalism to the extreme when you’re talking about powered transportation. The self-balancer is reminiscent of a Segway but the rider sits astride one wheel rather than the standing form-factor that [the Woz] loves so much for gaming. Looks like Ryno Motors is trying to gather capital to put these into production. We’re not going to hold our breath until we see them in the wild, but we’d be surprised if they don’t pop up on the big screen at some point in the near future.

Microscope camera adapter

[Ben Krasnow] is capturing some great snapshots using a microscope adapter and some tricks. The camera attachment is just a lens adapter ring with a tube added. Unlike other microscope imaging hacks we’ve seen he used a real microscope but found that the pictures had a bit of light distortion to them. The camera sensor was picking up a glare reflected on the inside of the black tube. By adding a washer and repositioning the apparatus he got over that hurdle. The final part of the puzzle is image processing. By taking several pictures at different focal lengths and compositing them he gets killer photos like the compound eyes of that house fly seen above.

1W blue laser – remarkably easy and dangerous

We’ve been covering Laser Hacks pretty much since the beginning but it’s surprising to see the niche market that has sprouted up around building powerful handheld modules. [Styropyro] filmed the video above as a tutorial on building a 1W blue laser. The “flashlight” that he starts with includes a heat sink intended for a laser diode. It seems there’s a lot of choices when choosing one of these build kits. A one Watt blue laser diode is press fit into the heat sink and wired in place. The body of the device receives a boost converter to get the batteries up to 1A, and once the assembly is complete the burning begins. It lights candles, matches, and pops balloons; the normal laser demo goodies.

So it’s a pretty easy build. But it’s also easy for someone being careless to damage their eyes. As [Styropyro] mentions in his comments, just looking at the dot created by the laser will damage your sight.

Microsoft engineers reinvent the Optimus keyboard

Looks like Microsoft has come up with a pretty slick little keyboard. It’s very much like the Optimus, which has an OLED screen in every key, except that it doesn’t have a screen in every key. Instead there’s just one screen on the whole unit and they keys have been overlayed on top while allowing the image to show through. Brilliant really, since this should drastically reduce the $2400 price tag of the original. That is, if you could buy the device. Microsoft’s not selling this hardware (yet anyway), but offering it up as test hardware for the UIST Innovation Contest. It will be interesting to see what the students come up with. This keyboard should be easier to program for since it involves manipulating just one screen. There is also extra space at the top that is touch-sensitive. See for yourself after the break.
