My station isn’t working anymore. I fear the worst because the web server isn’t starting up and it’s not responding to ssh anymore. I’ll have to disassemble it and see if the HDMI and keyboard will work.
I’ve had it for about a year, and I wanted to share some thoughts about it.
I used a Raspberry Pi 3 B+ for my RS4D, and I added enough SD disk space to handle a couple of years worth of data. I even increased the maximum number of days to keep to 360, and I think the filesystem only got up to about 53% usage. The most unreliable part of the system seems to have been recovering from a network failure. It would keep recording the data according to /heli/, but it would stop uploading the data. It would never recover from a network failure automatically. That would either require a toggle to off-line mode or a reboot. Even then it was unreliable on whether that would resolve the connection issue. It would be nice if the software was smart enough to reconnect to the Shake network when there is an issue, like if you unplug and replug the ethernet cable. If the web server is fine, then uploading the data should be fine too. After the last reboot, it never came back. Previously, if I just let the computer cool down for an hour by powering it off, it would start up OK.
I stored the device on the cement slab floor in the garage. Sometimes it would get hot. I think the hottest that I noticed it get to was about 160°F. Lately it was down to around 128°F. I suspect that it may have been hot for too long and on for too continuously. I stored it in one of those outdoor boxes to keep the bugs and dust out. Though I did modify the housing so that the cables would pass the cables through instead of using the connectors.
Are there any suggestions on lengthening the lifespan and improving reliability of a Raspberry Shake? I suspect that a passive heat sink that could expel the heat out of the plastic container could have helped, but I don’t know where I could get that or how that would fit. Computers don’t like to overheat.
If there aren’t hardware solutions, I guess I could review the software and make suggestions on how to reduce the CPU workload and thus generate less heat. That would just take time, since I’ll likely have to rebuild the system.
What are your thoughts?
