  101   Sat Oct 15 21:59:13 2022 Jennifer HritzGeneralOptical ContactingHot plate PWM v2.6 Test #1, 2, 3I realized that, after changing so much
from v2.3 to 6, I should check that my first
two tests produce correct results with the
  102   Sun Oct 16 14:20:32 2022 Jennifer HritzGeneralOptical ContactingSamples after 2 weeks under pressureSince I was focusing on the hot plate code
and therefore did not need my weights, I
decided to leave them on top of my samples
  103   Mon Oct 17 23:17:25 2022 Jennifer HritzGeneralOptical ContactingTesting PWM code with actual samplesNow that I have (relatively) good PWM code,
I wanted to do my first real test with actual
samples. Since everything went smoothly,

change the contacted surface area greatly,
but there is too many factors to speculate
  105   Wed Oct 19 21:51:10 2022 Jennifer HritzGeneralOptical ContactingThe trials and tribulations of the thermocouplesI intended to test the new thermocouple
set up today, but when I plugged them in,
both did not read a temperature. It took
  106   Thu Oct 20 22:43:05 2022 Jennifer HritzGeneralOptical ContactingWired the thermocouples backwardsSince the two devices are giving different
temperature readings, I would like to find
out if this imprecision is linear (e.g. they

doing prior (+180°C in 10 minutes)
but now with the (correctly wired) thermocouples
  108   Sat Oct 22 21:18:56 2022 Jennifer HritzGeneralOptical ContactingPWM v3.0With v3.0, I took a couple steps backwards
by getting rid of the feature that increases
the heating rate so I can isolate the base
  109   Sun Oct 23 21:01:40 2022 Jennifer HritzGeneralOptical ContactingPWM 3.0 (+280C in 5)I decided test how fast the plates
would heat up if the heat was just on constantly
on for 5 minutes. In general, these tests

faster than the top plate, I decided to try
increasing the cycle period from 1000ms (1s)
