We've made a handful of changes to make the CEE easier to calibrate and more robust to use. Channel-specific current limits, required to keep the CEE operating safely off your computer's power, are now independently calibratable. The "measurement" part of the CEE is now fully buffered - we added an extra bit of analog circuitry to greatly increase the CEE's ability to measure tiny signals, like those generated from thermocouples and photodiodes.

We'll be ordering the next round of prototype boards tomorrow and they should be in hand in approximately ten days. Firmware and PC-side software development are continuing in parallel with hardware revisions.

We're hoping that this will be the last revision of boards before we start production.
