HOW TO – 16 Channel serial servo controller for robotics…
This article describes a servo motor controller that is able to control up to 16 hobby servo motors and its based on the AT90S4414 microcontroller (a member of Atmel’s AVR Family). This servo controller is ideal in cases of building small robotic arms (3 to 5 axes) or small walker mobile robots (quadrapods or hexapods). The servo controller receives position commands through a serial connection which can be provided by using one I/O pin of another microcontroller, or a PCs serial port! Link.

Wow, great news – now I can keep track of the stuff I want to do in the virtual world – “Web-based event-management service Eventful has opened a public portal to the strange goings-on inside virtual world Second Life. The Second Life Event calendar, formerly hidden from non-residents, is now indexed regularly by Eventful, which listed over 1600 searchable virtual happenings last month alone and expects to index about 400 events daily. Virtual-world residents can travel directly to event locations via Eventful by clicking an embedded link in each entry containing exact coordinates. Event-listings, which are updated regularly, can be subscribed to in iCal and RSS format.” [
This scanner can actually play music, nice hack – “That’s right. The HP ScanJet 4c’s SCL (Scanner Control Language) command set includes an unofficial PLAY TUNE command. I stumbled across this after reading an article on the ScanJet 4c in the feb. 
Interesting game hack… apparently Counter-Strike removed the cross-hairs for the sniper rifle to make it a bit more realistic (that is, they remove the cross-hair when the scope is not in use). With this trick a sniper will be able to accurately shoot in short-distance battles, all using a Sharpie. Thanks Ghia!
