A new high accuracy tilt sensor

Last week I participated in a competition where I had to present my work. I didn't want to go there with just a few PowerPoint slides, I wanted to show the jury how the FCDT works in real. So I built a presentational box which task is to visualize the Linear FCDT's current tilt. I designed it to be convenient, so you'd just simply plug in the power cable, attach the sensor, turn it on, and that's it.

The box consist of a spec IC for signal conditioning (Analog Devices - AD598), a power supply witch provides +/-15V for the signal conditioner, and an UNO to drive the LCD and read the analog output of the signal conditioner. Of course, it's just a presentational device, it won't show the tilt with a 0,0001 degree accuracy, since the Arduino's ADC is just 10-bit, and we'd need at least a 16-bit ADC for accurate measurements.

Here is a little video of the device in working:
