Bonlebon writes in about the arcade cabinet he built – “My Mame cabinet, the Procrastination Station. Time from deciding to do it until finished project: about 6 months. Money spent: way too much. It was a lot of fun though. I still have a few things to finish up, but it’s definately playable.” Nice work! Link.
Matt writes “My short how-to on making a doorstop form pvc pipe. I like to think of pvc pipe as the modern day erector set….an old house and the inherent settling which may and does occur; our floors and doorframes aren’t exactly level or square. This being the case my office door has a tendency of closing on its own ever so slowly. While I have done my best at making adjustments to the hinge locations it still wants to close. Now I could buy a doorstop at my local home improvement mega-store but what would be the fun in that? Hence my homemade pvc doorstop.” Link.
Here’s a great how to for simple bot “The following article will show you how to build a simple robot, called “The Beetle Robot”. It’s great for beginners and easy to do. Most of the components can be bought for much cheaper at Digi-Key, Jameco, or similar. At Solarbotics you can find the dual AA battery holder and the Mabuchi motor. You can find these components at any good electronic store.” Thanks William! Link.
Alex writes “There was a Videopac 7400 with a broken power switch in the attic. Next to it was a NES which only life sign was a blinking power led and blinking screen. These would be my two victims: I would try to fit the Videopac inside the NES-case. Not hindered by any technical skills whatsoever and with a newly acquired dremel-clone, I made a start.” Link.
David 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.
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.
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. 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.
