Reza’s Rants

I had some PCBs made up to do some bioimpedance spectroscopy for edma detection through the cole-cole model. One set has an MCU & space for a bluetooth module meant to communicate with an android tablet.  The other is a stand-alone module that I’m going to try and interface directly with a microtouch avr touchscreen.

These will go from 1kHz to 100kHz.  If you notice the big PCB, I made the VIAs have a teardrop shape – they look cool.  It’s based on my design for a fixed 50kHz device for impedance plethysmography that I use to measure respiration.  Fun stuff!
