CNC SIG

[Peter Menningen]

The Space will be open tonight for the CNC SIG   We will be working on installing the DeWalt spindle on our Shapeoko as I now have a set of mounts that are suitably strong and solid enough for the task

EDIT tonight is Raspberry PI sig not CNC

[Ross Mukai]

Pi! I'm super stoked I made a little addon for our arduino door with the pi. Gpio to relay to close the magnetic strike and open the door from URL on private network. Gpio is controlled by wiringpi and php, it was a super simple 

gpio -g mode 6 out

<?php

exec("gpio -g write 6 1");

sleep(3);

exec("gpio -g write 6 0");

?>

It's not opto-isolated but super handy and fun to play with for low voltage stuff. Planning to use this circuit to drive stack lights, probably using an embedded atmega to keep the cost down. 

Costs about $1 or so worth of components
