Evil Mad Scientist Laboratories has put out this nice tool. It’s a Zif socket for Arduino. If you’re doing a lot of flashing, this could be a nice addition to keep from having to pry your chip out every time. Plus, it looks cool in a soviet era technology kind of way.
[Rhys Jones] has been working with the RepRap team to develop a way to print circuit boards. The machine first prints the plastic substrate with channels for the metal to be deposited into. They adapted their pinch wheel feeder to work with solid core solder (flux creates a mess). The extruded solder’s specific heat isn’t hot enough to melt the plastic. They made a video (embedded below) of their test piece: an optical endstop. The team has also been experimenting with decoupling the feed mechanism from the extruder.

[Jed] from Toronto’s hackerspace HackLab.TO coded the theme from Super Mario Bros. for their laser cutter. He’s posted the ruby code that generates the g-code from a simple tablature.

We might have to add a category of “stuff made to twitter”. The latest installment is an office chair that twitters whenever it gets farted on. The author has a smart sounding description as to why he decided to make this, and he has a pretty good point about twittering interrupting the things you’re twittering about, but it all boils down to the fact that he wants to twitter his farts. We can’t say that we didn’t expect something along these lines. He has mounted a natural gas sensor in his chair, along with a squidbee wireless transceiver. You can download all the code as well as see the construction in the instructable. You can also follow his flatulent adventures on the twitter account of the office chair.
When we compiled our list of real life power suits last May, the HAL suit was being pitched as a $1000 a month rental. Cyberdyne has changed their tune for the better recently. Teports suggest that the first 400 unit run of powered exoskeletons will sell for $4200, less than a Segway. The suit can increase the wearer’s strength ten-fold and will run continuously for nearly three hours.

[Markus] noticed a lack of 7 segment LED displays that could show RGB. Like any hacker, he sought to remedy this. The solution he came up with was to basically remove all the electronics from the plastic body of the display. He then mounted new surface mount RGB LEDs in the correct places. This may be a bit messy, and definitely increased the footprint in this layout, but as you can see from the pictures on his site, the final result is quite nice. What uses can you think of for these?
[Mike] takes us through the process of adding a removable high gain antenna to the WRTSL54GS in this article. The antenna that comes on this unit from the factory is a bit small and underpowered. After upgrading it using OpenWrt, an open source full featured router software package, he felt it needed a beefier antenna. So, he cracked it open. The new antenna can simply be soldered in place, where the old antenna was.
