Apparently I can only connect to this log from within the network. I tried from home a few times and kept getting connection reset.
Thursday:
Steps for preparing strain gauges:
- Warm resin to room temp
- Sand surface that will have SG attached
- Clean with acetone until the Q-tip doesn’t get black anymore
- apply conditioner
- neutralize
- Apply resin and wait for it to dry
- Apply second layer of resin, attach strain gauge and allow to dry
- Test resistance with tester
- Cover with polyurethane
- Protect connections with silicone
Cleaned up code a bit from when I changed it
Friday:
- Second SG stick was ready to use. Noted a lot of problems with calibration and consistency.
- Phil recommended averaging samples to clean up the signal inconsistency
- Showed it to Clift and he said that the signal wires needed to be shielded because the magnetic field from the motors were causing interference.
Saturday:
- Attached shielded cable to the SGs and Wheatstone bridge.
- This helped a lot with holding the calibration and consistency.
- There are signal wires going from the wheatstone bridge to the amplifiers which are still not shield which may help with lowering the inconsistencies when not in the dead zone as well as it still loses calibration sometimes.
- Averaging the samples is probably still a good idea even if it seems to be working perfectly(which it isn’t now) without it.
- Started reading OpenGL book but haven’t tried any tutorials yet.
