PSP 2.0 Update DO NOT UPDATE!
Over the next day and week you’ll hear about the new PSP 2.0 update from all the usual places, but don’t update- really. There are a couple new features, like a web browser, image transfer/wallpaper, some other video and network tweaks- but it’s a yawn. You’ll lose all the amazing homebrew playing capability, emulators and cool applications the PSP makers are cranking out- so don’t do it- it’s just not worth it, it removes fun (until the version 2.0 firmware can play homebrew, then it’s ok to update).

Very clever…simple, customisable, do-it-yourself signage system. By “blacking out” elements of a 14-segment display font on the tape, all you need is a black permanent pen to create your own temporary signs, labels and installations. Think moving house and labelling boxes, putting up official-looking signs or teaching your kids how to make letters. [
Gkaufman’s used 2 PC expansion slot covers to create a new mounting bracket for his bike’s rear carrier. He wanted to pull the rear rack off of his old bike and mount it. The problem was that the rack’s mounting bracket wasn’t designed to fit this style of bike. More details on the project blog 
No User Serviceable Parts Inside? – a Maker’s bill of rights…Mr. Jalopy has a list of “rights” I think we’d all like to see as Makers when we buy our gadgets, parts and equipment. Screws not glues, replaceable batteries, stuff like that. The days of the Color TV tube tester at the drugstore are gone, but why give up control of what we buy? 
…a solar-powered bike light, modified from a solar flashlight. (I did find one product that is advertised as a “solar bike light”, but it’s not good: it uses an incandescent lamp rather than LEDs, and it’s a one-piece unit so the whole big thing has to mount on the handlebars). With my home-made version, the solar cell and batteries mount on the rear rack, as you see here. 
Great project- My ROV, “Bob” is based on the “Sea Fox”. It uses 5, 500 gpm Johnson Bilge Pumps ($10 Each) for thrusters. Unfortunately these pumps have increased in cost to $20 since I built Bob in 2002. If you have more time than money you can convert bilge pumps to use propellers similar to a boat and then reverse wire the so you can reverse them. Since each motor can produce forward and reverse thrust you can design and ROV with only 3 motors. The control is an old Atari switch type joy stick ($10 on ebay), that now houses a 9 volt battery, and is wired to mechanical relays on the ROV using Cat-5 (Standard 4-pair Computer Network) cable. An extension cord provides power to the ROV from a 12volt trolling motor battery”. [
Why would you want to interface the Keyboard? The IBM keyboard can be a cheap alternative to a keyboard on a Microprocessor development system. Or maybe you want a remote terminal, just couple it with a LCD Module. Maybe you have a RS-232 Barcode Scanner or other input devices, which you want to use with existing software which only allows you to key in numbers or letters. You could design yourself a little box to convert RS-232 into a Keyboard Transmission, making it transparent to the software.
