Happy New Year!

2017 is upon us, and we’ve kept busy as usual. One of the main goals for this year has been to get a working prototype as close as possible to “the real deal”. This means being able to amplify, digitize, demodulate and transmit data over serial to a host computer. I’m happy to say we’ve managed to accomplish this, after a dash in the days between winter solstice and new year’s celebrations.

The quickly cut together video below shows how we’ve gone from a fieldmill assembly on its own, to a partially assembled cube, to the fully assembled cube in our test box. Some final screenshots demonstrate data being analyzed in LabView and GNU Octave.

The focus moving forward is making sure we only use materials which are high-vacuum compatible, to be able to do thermal tests on the design we’re currently working on. There’s also more work to be done on the simulation front, and various bits of code need to be written.Parts for a piece of calibration gear has been ordered as well, which is needed to verify that the entire analog frontend works as expected. In short, 2017 is going to be a busy year!
