Pramode C.E. writes – “With a low-cost general purpose microcontroller like the PIC16F628, bits and pieces of cheap, commonly available electronics components, and LOTS of code, you can build many interesting `toys’ and hook them up to your Linux machine – a really great learning experience for the hardware hacker who wants to learn Linux, or the Linux hacker who wants to learn a bit of hardware. This article describes how I went about building my temperature-sensing project – amateur Linux/hardware hackers might find some of the ideas useful when they start building things on their own.” 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 – Controlling a relay and motor with a serial port…

SerialChad writes “For a while I have wanted to control things with a serial port. It was pretty easy to control a relay with a serial port. With a standard serial port you can control 2 relays. (with a parallel port you can control 8 relays, but I don’t have a parallel port on my system). A standard PC serial port has 9 pins. Pin 4 – DTR (data terminal ready) and Pin 7 – RTS (request to send) can be used to control a relay. These two ports don’t actually send data. They are used to signal the other device to tell it when to send data.” Here’s the HOW TO – Link.

HOW TO – Optical mouse to scanner…

BoodschappenTurn your optical mouse in to a scanner! Erik writes: “A Maker posted his project on a very large Dutch forum, after he read some datasheets of the sensor in his optical mouse. He wrote a application in VB for reading the sensors outputs, so he can use the sensor like a hand scanner. The software is available on the site and works on mice which use an ADNS-2610 optical sensor, recognisable by the eight pins, the sun-like mark and the text ‘A2610’.” Link.
