Sensory Software Grid 3 control problems
Log from communication through gesture

Log from SNAP: Augmented Echolocation
SVO is looking to be our next sensor of choice. I want to discuss some of the pros and cons of this method, as well as compile some project learning resources. To define the desired feature set of the vision sensor, we should first recognize that...

September 28th 2023: I can't make the linear actuator move precisely

For some reason the 47 pF value for the caps is sitting in my mind. Either after 'calibration' the LC meter is so far off that it read both my TI-89's and my V200's caps 51 pf, both ~8% high, or both of them are within their 10% tolerance and reading...
