Hi, my was having a Chemostat run, but found that the reactor was completed dead in the morning. There was no liquid around.
I reconnected the power input and so on, it didn’t have any light flashing. I think the PI was dead, maybe over heated because I saw the bottom of the pioreactor.
Now I reassembled the reactor part with another controlling part, resumed the run. How can I confirm the problem of the “dead” one? Any suggestion to avoid similar problem? Thanks.
It’s pioreactor 20ml, v1.5; with Pi zero 2WH; culturing at 37C 500 rpm, medium exchange every ten minutes.
Hi @hai1234, I’m sorry to hear about this.
This seems fine, and the “heat” mark on the sticker is normal (we use thermal paper for those stickers, so this is normal behaviour - it’s on our list to update).
Now I reassembled the reactor part with another controlling part, resumed the run.
Anything odd in the logs? Can you share them with me for that experiment? hello@pioreactor.com
To confirm the Pi’s dead:

That’s pretty solid evidence. If you try this again, be careful as some components might be shorting and getting hot.
- If you have a multi meter, you can check the 5v, 3.3v and GND pins.
- Look for any burn damage on the board. If you have a thermal camera, plugging power in, and looking at the board can usually spot the component that is damaged.
I couldn’t really see any problem from the logs. Just sent you the log. Thanks.
