HOW TO – ATX -> Lab Bench Power Supply Conversion
New Instructable on how to convert a computer power supply into a power supply for a lab bench, mat_the_w writes “I started into my main electronics classes, and needed a good power supply for working on lab projects at home in my room. My roommate Adam told me about somebody online who had converted a spare ATX computer power supply into a lab bench power supply, so I decided to do the same thing.” Link.
Ask MetaFilter has an excellent question (How to make things?) with some great replies – “I’m looking for books that tell general building techniques, for example, how to weld, basic wood working principles, how to fabricate things, etc. Also, websites or blogs that cover that sort of thing would be nice. Also, I’d prefer books that suggest ways to build things without a lot of tools (For example, I own a circular saw and a Jigsaw but no table saw). In short: I’m looking for things that will teach me basic building techniques from wood to metal and electronics.”
Matt writes “Strangely aesthetically pleasing window blinds made out of junk mail. By affixing strips of junk mail to an existing set of venetian blinds, one can drastically reduce the amount of light allowed through without losing the ability to raise and lower the blinds. In my case, about three months’ worth of junk mail, but your mileage will vary. Your trusty roll of duct tape (color to suit). Two rolls of scotch tape. A ruler. A spool of uninsulated wire. A pair of needle-nosed pliers. A thumbtack. Space to work.”
Great LEGO project, I’m hoping they release the code – “Introducing GameByEmail’s Dice-O-Matic. Made from Legos, a USB camera, and a bit of software, it’s a home-grown, dice-rolling monster. Don’t let it’s rickety looks deceive you; this puppy can easily crank out the 20,000 rolls a day consumed by GamesByEmail. In fact, at full speed it averages almost one roll a second, well over 80,000 a day!.” [

Great article by Cory Doctorow in the NYTimes about FabLabs and beyond…“Plastic created the age of whimsical forms. Suddenly a radio could look like a moo cow. A chair could look like an egg. Toy ray guns could bulge and swoop. The exuberant designers of the golden age of plastic explored all the wacky, nonfunctional, decorative shapes that household objects could take. Now that same plasticity is coming to microcontrollers, the computer chips that act as brains for the chirping, dancing, listening and seeing devices that line our knickknack shelves and dashboards and fill our pockets.”
I’ve always thought instant messaging was fast lightweight way to get information – often better than opening up a browser on your computer, or trying to use a phone to browse the web. So, we’re now in “beta” of a new way to get the latest from MAKE, it’s a little MAKE buddy you’ll be able to add to you buddy list on AIM/iChat. Right now you can get the latest posts, news, gadgets and events from MAKE, and have the little MAKE buddy message you when there are new posts if you choose. We’ll also add queries, for example you could type “How do I weld” and the buddy would send you a link. Here’s a screen shot of him now, once he’s ready for more testers I’ll let you know! Image –
