I didn't want to have to do this, especially so late, but I'm going to have to drop out for this year. I've been sitting on the ingredients for a few months, but due to an injury I've physically been unable to do the work of actually brewing yet. I keep thinking I'll be back to brewing "any day...
I've got a spare board I can part with, and I'm also in CA. It's the previous version of that board (the Jeffrey 2.1) but the changes between that and the newest are pretty minor.
If you're interested, send me a PM and we can discuss details.
Everything should be in the disk image. At this point I'd suggest plugging a keyboard and monitor into the Pi and seeing what occurs when it boots up on the copied card. It could be a bad card or something.
I'm not too worried about how accurate it is, the battery lasts plenty long enough as it is. I just set it once during initial setup and haven't looked at it since.
The iSpindle reads a value that it converts to the battery voltage using a formula based on resistor values and a conversion factor (default of 191.8).
For instance, the iSpindle is telling you the battery is 4.15V. You take the battery out and measure it with a multimeter and it's really...
What is the mAh of your batteries? Signal strength could have something to do with it, but that still seems quite short. I ran a mead (in a plastic bucket, no refrigerator) for just over 2 months at 15 minute intervals on a 3500 mAh battery. I've got another brew going on that same iSpindel...
If is going ground and cross country, you'll have several days of no updates while it's on a truck between distribution centers... Made me a bit nervous the first few times tracking just seemed to stop the day after I dropped it off.
Looking forward to this! Been following the 2020 thread with interest for the few months I've been back, but I was a little late to get into it.
I've already got one of these next up on my to brew list to age for next winter. Crossing my fingers it's not taken by February, but there's plenty of...
Regarding food safe filament, this video from Prusa may give a little insight.
Personally, I'm less concerned with the filament being certified food safe, any contact with beer will be minimal and temporary. The beer should never be high enough to reach that spot except for some splashing as...
