HOW TO – Furious contact microphone assembly

HOW TO – Furious contact microphone assembly

FinalErinys writes “Here’s how to build a contact microphone. A step by step I put together years ago, but it is surprisingly still of use. Contact microphones may be used to record acoustic waves that propagate through media such as wood, sheet metal, or a block of ice. Doesn’t sound “pretty” in a classical sense, but if you’re into noise and field recordings, you’ll love what you can coax out of an old tin can with one of these attached.” Link.

New Brother Innovis Sewing Machine in Japan

Forget mobile phones, even the coolest crafty gadgets seemed to get launched in Japan first. Starting in Feb, Brother will launch a new line of three embroidery/sewing machines that have preprogrammed designs from Peanuts, Disney and Hello Kitty (of course)! This one doesn’t seem to have a USB attachment option to a computer, but there is a card reader so you can also do your own designs and load them up on the machine. You can also download more designs from their special site on the Net. Brother also will be selling software so you can convert your digital photos into embroidery. Not sure if its an update to their existing software mentioned here in a software review. Link and translated press release.

Build a LED matrix clock

Build a LED matrix clock

ClockbacksHans writes – “This LED Matrix Clock is a feasability study for a much larger project I am building for my employer, the intention was to prove to myself (and my employer!) that I am able to drive an LED matrix from a PC. This is the first project I have made which is driven by a PC. The clock uses 3 B64CDM8/B48CDM8 8×8 5mm LED Matrix modules from Nexus Machines, each having an onboard MAX7219 display driver chip. These require an SPI serial interface, which I by toggling pins of the host PC’s parallel port (printer port). The small software application which drives the displays is written in Delphi 5 and runs on Windows NT 4.” Link.
