Hackaday Links: February 1, 2012

The only thing he needs now is a micro and RTC

For [Dino]‘s 44th Hack A Week extravaganza, he made powered window blinds in five minutes. It’s a simple build with a small gear motor and a bit of tubing to adapt the shaft to the control rod of the blinds. Good job [Dino].

The wonderful [Lizzie] over at LUSTlab realized that typing meta keys really slows down the development process. The result? Foot pedals for the Shift and Command keys. No build log for this one, but it’s just a set of old racing pedals and a disused keyboard.

So much cooler than a potato

[mdevaev] out of Russia built a fully articulated GLaDOS replica. Here’s the build album and the relevant MLP forum post. This GLaDOS is tiny – probably less than a foot long, but it moves around and speaks (Russian, which is weird). Somebody get us a couple of motorcycle fenders so we can build the 1:1 scale version.

Visualizing a plane of fog

[greg] was looking for a way to visualize the chaotic turbulence of air. He mounted a laser on a computer fan and held some dry ice above the beam. The result looks like it could make for an interesting photography project, but check out the video if you don’t believe us.

We were asking for it

We asked for battery charging circuits that don’t use specialized parts. [Petr] found this one that only uses few transistors, a MOSFET and a voltage regulator. In one of the Hackaday comments, [atomsoft] had the idea of putting a USB plug on the traces to save a bit in component costs. [mohonri] said he designed one, but we have yet to see it. Perhaps next links post…

Lego modded antenna tuner

legomoddedtunner

This antenna tuner is controlled remotely using geared motors and legos. The tuner needed to be closer to the antenna for performance reasons. This created a problem; most of the radio gear is inside while the tuner is outside. The gear motors and Legos combine to form a closed loop servo, operating two air core caps and an inductor switch. A control box placed near the radio is hard wired to the modded tuner outside. We would like to see something like this under gesture control using the Wii MotionPlus + Arduino.
