I am familiar with Adruino's but they are way bigger than the 'tiny' PCB's I mentioned. You can hide an MSP430F2012 PCB under a quarter.A whole socketed MSP430F2012 (or 2013) PCB _and_ the USB programmer is the size of a USB thumbdrive. f2013 has programmable gain for the A/D if needed. Many 3D printers have moving extruder heads driven on 1 axis by a 1/4" XL belt, and weight may affect speed and accuracy. The idea I addressed was to mount the A/D conversion on the printhead with no thermocouple wire flexure and use cheaper easily replaced wire to communicate with the rest of the system via protocol of choice. A 3.3V Adruino is a fair choice if the size and weight are not an issue. (for BBB interfacing) I don't know where to get 3 Adruino's for $16 though. Could mount a suitable AVR device on a similar sized PCB! Whatever flavor you prefer, there are inexpensive MCU's available that might be substituted for a dedicated A/D. If one were so inclined. :) ------------------------------------------------------------------------------ Introducing Performance Central, a new site from SourceForge and AppDynamics.
