Sorry for the long gap in between updates.
Addressing Nem’s comments: we cut the NUC power supply cable to power the NUC using the custom power board. It works, unlike the laptop charger cable. We’re guessing its failure may have to do with Nem’s suggestion about center pins or too thin of a gauge to handle that much current.
We can upload the camera and telemetry board sketches to readout the reported information from both of the Arduino micros when they are plugged into a separate computer (e.g. one of our laptops) while everything except for the weather station is powered through the power board, but we cannot upload the same sketches when the micros are plugged into the NUC. This is one of our bigger concerns, as right now our unit can run, but won’t function autonomously in real weather conditions.
Our AC-DC power supply unit is the PowerStream PST-SP12AL. We measure 12 V DC converted from mains power.
We use the NUC5i5RYK, but looking back at our parts list, I see the hyperlink points to the NUC5i3RYK. Maybe we bought something which nominally requires more power than the custom power board can provide, at least without restricting its performance in the BIOS? Could this be why we get thermal trips when resetting the device? This model has a solid state hard drive. We have turned off the audio and bluetooth options in the BIOS. We still use a monitor, so we have not disabled HDMI/display ports yet.
As far as running the unit, we tested it out on the UofA lawn during the Thanksgiving break. We sorted out a number of practical issues (cable lengths, powering the unit, focusing the cameras), but we need a better location to perform a real polar alignment - street lights plagued our field of view. We are requesting access to put the unit up on the roof of Steward Observatory so we can ‘calibrate’ it and maybe try to measure a transit curve in the near future.
