Description

I put this project together for the OSH Park Bring A Hack meetup at the 2016 Bay Area Maker Faire. It's Tricorder inspired, but can't quite sense everything, so the name "Bicorder" seemed fitting. It currently has a 3-axis magnetometer, a relative humidity / temperature sensor and an infrared range finder. It uses a 128x32 pixel monochrome LCD from Newhaven, which is divided into left and right sections, each displaying one of:

* live plot of temperature (in Celsius)
* live plot of relative humidity
* live plot of magnetic field (Z-axis) in uTesla
* a compass display (using the mag X and Y)
* a distance readout in cm

It's the first real project I've done with the MoonLander board: https://hackaday.io/project/9176-moonlander

Enclosure design files

I just pushed the design files for the enclosure to Github - I laser cut the top and bottom and 3D printed the walls.
I was worried about the overhangs on the cutouts for the USB and range finder, but my printer handled them just fine.
