Milkscanner – 3D Mapping That’s Good For You

June 5, 2007 by 25 Comments


[Blind Tree Frog] sent in the Milkscanner. It’s an oh-so-simple method of mapping a 3d object. [fiezi] used a small tub, a lego mounted webcam, a small supply of milk and a bit of software to create the map and import it to moviesandbox.. The object is placed in the tub, then then it’s scanned by the camera as the milk level is slowly raised (in this case, via spoon power) and voila: 3d map.

Video is after the jump, or at the top of the read link.

CNC Solder Paste/pick N Place

June 4, 2007 by 15 Comments


Just when I thought I’d seen most of the CNC mods out there, [Steve Ciciora] (who happens to be one of the driving forces behind the killacycle) sent in his diy solder paste dispenser *and* his diy pick and place machine. Both are extensions of his CNC taig mill. Hopefully [steve] will put up some more details of his mill mods.

Energy Efficient Cat Camera

June 2, 2007 by 50 Comments


[Juergen] sent in his catcam project built. He used an inexpensive 1.3mp keychain camera with an ATTINY2313. The controller keeps the camera shut down until it’s time to take a picture. Then it powers it up, takes the shot, and returns to low-power mode. The cat adventures are actually kind of interesting. It wouldn’t work from under the car, but anyone feel like gps tracking their cat?

Wireless Reef Automation

June 1, 2007 by 5 Comments


I’m on a 1-wire/home automation kick lately. It looks like he’s giving up on the router platform, but [barebottoms] did some interesting work with a couple of wireless routers (a belkin that he fried, and then onto a wrt54g) to create automated controls for his reef. Think of it as home automation for the fishes. It’s an interesting idea – a hacked wireless router could make a fairly robust and power efficient controller for simple HA applications. His site isn’t really that informative, I found the forum posts more interesting.

UK Power Meter Monitor

May 30, 2007 by 14 Comments


[john] sent in his version of a power meter monitor. It’s designed to monitor the blinking light on the meter to monitor the current power usage. The light flashes in proportion to the amount of power being used, so it was a matter of using a ldr/photoresistor to capture the output and feed it to the parallel port of his computer. To finish it up, he used a shell script to feed the data into MRTG.
