Automatic Cable Modem Power Cycling


If you’ve got a cable modem, you know the drill when it goes offline. Unplug it, wait 30 seconds, plug it back in, reset your dhcp request. I’m pretty sure that [brian] mentioned this in a comment a while back, but now he’s written it up. He’s using a cron job on his linux box to check the internet connection, and if the test fails, power cycle the hardware with some X10 hardware and a little scripting. (Just don’t tell your friends or they’ll be outside trying to guess the code.)

Milkscanner – 3D Mapping That’s Good For You


[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.

Serial Port Power Booster


This one(coral cache) is a bit of a head slapper, but I thought it might come in handy. Laptop (or usb) serial ports are pretty notorious for being stingy on power output. [Roberto] came up with a clever solution. He used a MAX205 (sort of a double+ MAX232) and a singe capacitor to convert the low power serial connection on his laptop to a TTL signal and back again to RS-232. The result is a simple dongle that needs 5v and gives you a high power serial port for those power hungry devices – like [Roberto]’s PIC programmer.
