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.
Reven writes “Yesterday I received my minipov kit from adafruit industries (MiniPOV 2 kit) [from the MAKE gift guide]. I just love it. It is very easy to make. Clear instructions on the web with lots of great photos (I definitively need a tripod). It’s easy to program too and all the source code files have a lot of useful comments. Overall it’s a great gadget and the price is quite good. I did have to pay $6.60 for postage, though. At least adafruit does post overseas. I did some tricks in front of a mirror. Almost had more fun taking photos than building. I’ve even set up a flickr POV set. For your pleasure.” Link.
Here’s the latest on the iPod breakout box, now you can control it, and poke at it…Panocamera writes – “The iPod breakout dock was the first step in creating a microcontroller interface to the iPod. The next step was to create a serial command protocol testing program so that I could send the iPod command sequences and watch the responses from the iPod in order to figure out a sequence to reliably control and command an iPod externally.” Link.
