Anyone ever use/see this in action?

DIY Carpet Tile Sample Area Rug…

Carpet RugDavid writes – “I’ve found a great new use for the old carpet tile samples my Architecture firm gets. I taped together some matching samples to make a rug for my pad. I originally tried this with Interface carpet tiles and carpet tape. The Interface carpet tiles are good for this, because they have a nice, firm, rubber back to them, however, this makes the rug hard to overturn when you’re done taping the tiles together.” Link.

HOW TO – 16 Channel serial servo controller for robotics…

Pic3This 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.

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.” [via] Link.

ScanJet Music – Play music with your scanner

ScanJet Music – Play music with your scanner

ScanjetThis 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. 1997 issue of HP Journal (see the sidebar Sing to Me). The PLAY TUNE command basically varies the stepping rate of the scanner motor to produce audible frequencies. All it needs is a series of note frequencies and durations previously written to its SCSI buffer. ” [via] Link.
