Why don’t you just die.

As I am finalizing my MagneTag prototype for a small production run, I have been looking into efficient ways to cut fabric.  Right now I trace by hand and and cut with scissors.  I’m currently thinking I may want to make several hundred of these initial units.

With that in mind I am going to try die cutting my design with a shop press.  Since I’m not exactly sure what my final product will look like aesthetically, I am reluctant to shell out a lot of money to have a die professionally fabricated. What’s the fun in that?  I figured I would try my hand at a home brew hacked version.

I laser etched my design into two different substrates: wood and acrylic.  Then a took an old rusty bandsaw blade and hammered it teeth down into the laser kerf.   Then I took a Dremmel and ground a sharp edge into the steel.

An initial test on a manual hydraulic press gave mixed results.  The wood is too soft to keep the blade from becoming embedded; the steel needs to pass all the way through the substrate.  The acrylic seemed to work better, and surprisingly did not break when I tried to use it.

There is still lots of room for improvement, but I’m pretty happy with this first attempt.

Arduino Programmer Shield

I gotta say I’m pretty proud of my design for a custom programmer shield.  The images below show the Arduino, programmer shield, and a target board (ATTINY85).  I made the boards using the laser cutter method (which you can find videos of on this site somehow).  The target boards slip right into the header pins I bent up for the purpose.   Makes a really handy programming and testing jig!
