HOW TO – Make a CNC machine

Cnc1Rheslip made his own CNC machine – “I looked at a bunch of designs and decided to try a fairly simple 3 axis machine as my first effort. The idea was to use a Dremel tool for the cutting head and use the machine to engrave aluminum front panels for my guitar amps. As it turned out the machine isn’t accurate or rigid enough for that. A dremel just has too much slop in the bearings for accurate machining. The machine will do a reasonable job machining soft materials like plastic and soft woods, and it does quite a good job of plotting PCBs. I haven’t tried drilling PCBs yet but I’m pretty sure it’ll handle that too.” Thanks Star! Link.

HOW TO – Improved spam filtering

InstructablesExcellent suggestions on a DIY spam filtering solution on Instructables: “I have been using a method of spam filtering for a number of years that works well in sorting personal communication from channels that may induce spam. I generally issue one email address to personal contacts and a second is used when dealing with online forum, e-commerce etc where I expect that address will fall in to the hands of spammers. I have setup two gmail accounts and the ‘spam’ account forwards all mail to the ‘personal’ account which labels those received mails with a filter accordingly. By pushing spam filtering out to the edge of the mail client, the address, you take away reliance on spam filtering technologies which can be duped.” Link.

1.Laptop KeyboardChris writes in with something to do with a laptop keyboard: “Ever wanted a laptop keyboard to use with your stationary computer? Lee Char did and took a keyboard from an old Compaq and ‘converted’ it to be connected to his regular computer. This is something that would be interesting to spin further on by interfacing this keyboard with an PDA instead, like an iPAQ. Anyone have an idea on how to do this?” Link.

HOW TO – Make a quick, low-cost vibrating lockpick…

0Sam writes: “One of my favorite sayings is ‘all a lock does is keep an honest man honest.’ Any time a new gadget comes out that speeds up the ability to pick a lock it is often extremely overpriced. Any vibrating lock pick is a bit overpriced in my opinion, so here is a way of making a good vibrating lock pick for about $9.00 and a half hour.” This project turns a vibrating Oral-B flosser into a lock pick.

HOW TO – Add 20GB of external storage to the PSP

Psp2-1-2-1-1-1-1Steve writes “While I love my Playstation Portable as a both a game machine and portable media device, one of the biggest limiations is the fact you’re limited to the storage on the memory stick. Even with a 1GB stick, after you drop on a movie or two, you’re really limited in what you can store on it compared to an iPod.” This how-to shows how to use custom firmware on the WL-HDD 802.11g drive enclosure to add a built in webserver. By using RSS feeds, you can stream content directly from the drive to the PSP. Link.

HOW TO – Controlling the World with your PC

Serial-1Inverarity writes in regarding serial port projects for PCs – “There’s a great book for this stuff, Controlling the World with your PC, by Paul Bergsman. I loved this book when I was a young tinkerer (alas I have much less time for tinkering these days, which is why I live vicariously through Makezine.) Mr. Bergsman also used to write for Circuit Cellar, I think. The book has general tips for interfacing with the parallel port, as well as designs for driving LEDs, relays, stepper motors, and lots of other stuff. Great fun!” Link.
