temp: Increase filter time
...
Increase the filter constant to 100s to smoothen the signal a lot. For
online viewing, this is quite nice, but for acquisition, we should
probably look at the raw data...

temp: Slow down reports

Only send a new report every 200ms to hopefully mitigate the serial port
glitches.

temp: Actually calculate temperature values
...
Do the monster math to convert ADC readings into appropriate temperature
values. The absolute result is way off but it seems to respond sanely
in relative terms.
Additionally, apply a low pass filter with f=1Hz to smoothen the noise a
tiny bit.

Add sweeping notebook for X-axis sweep experiments
...
This is a hacked together X-axis sweep with a duration of 4.3 seconds.
The whole setup is quite janky because the sweep seems to only fill half
of the sample buffer. We probably need to dig deeper into the way the
red pitaya is working...

Fix spring dimensioning calc error

We have 4 springs, so the effective spring constant is 4 times higher.
Reflect this in the calculations and adjust the CAD model for the
updated spring length.
