Making Felt
Felting is the art of matting wool. Any kind of knit that you want more durable can be done through felting. The process of felting can sometimes seem intimidating or complicated. I love this complete feltmaking process with photos for every step from the Handweavers Guild of America. You can use the felting technique for creating ipod cozies, bags, bookcovers, you name it!

Chris writes “Considering how many people bought the HP Bluetooth stereo headphones and got disappointed when the headband snapped, I thought that it was time to do something useful with the ‘broken’ headphone. We’ll take you through all steps of dismantling the Bluetooth receiver and building it into a nice mouse housing with 12v in and line out. And as the device keeps its battery, you can also use this as a portable Bluetooth stereo receiver and plug in you high quality headphones or even connect it to your stereo at home.”
“In the November 1999 issue of EPE (Everyday Practical Electronics), a small and intriguing circuit was published in the Ingenuity Unlimited section by Z. Kaparnik. It was a very small implementation of a typical transformer feedback single transistor invertor. The transformer was a standard ferrite bead with two windings wound on it and the circuit was using the high voltage pulse generated when the transistor turns off to light an LED from a single 1.5V battery. This page has two variations on the original design to use the simple circuit in a useful manner.”
Pastelero has a great how to on controlling WinAmp via a serial port “Nowadays, winamp has full support to keyboard shortcuts. But some time, when winamp didn’t have this feature, I was thinking in some way to make a easy way to change music by simply pressing one button, it would make things faster and would help me to change music during games. So I decided to make a external control panel, to make it easier to change musics, volume up or down, toggle shuffle and many other features by pressing just one button. I found one winamp plugin that shows how to configure a external control using the Serial Port, being able to make 4 or 15 buttons control…” [
