Workshop Update for May 28th, 2012

Today we had meetings, cleaned up the workshop, and worked on our application to the Open Hardware Summit. OHS applications are due the 31st (Thursday), we’ll post ours as soon as it’s done.

We continued updating and cleaning up our Eagle part library, and made some adjustments to a soon-to-be-released PCB.

Capacitor measurement in now implemented into the Part Ninja firmware. The measurement is done by using a comparator to stop a timer when the capacitor is charged to Vref=2.5v ~ VC/2. With the known resistance of either 680, or 470k Ohm, the equation is C=Time/(R*k). Where k is the RC coefficient at which the capacitor is half charged.
