When i run "sudo systemctl status attiny_daemon" i get this error:

Can you tell me what is wrong?

Apologies for contacting you here, but I can find NO other way to get ahold of you (please create or otherwise expose a public-facing email address! It would be very helpful.).

I want to implement this device, using a USB power bank "kit" (a plastic housing and the power bank controller PCB, with room for up to six 18650 cells) and some 18650 cells from old laptop batteries. HOWEVER, I can't tell how to interface / monitor multiple batteries at once, and I'd be concerned about the batteries' respective charges getting out of whack -- I don't know much about LiPoly cells, but I know they have a nasty temper and I know that balancing cells is a concern. (...and, yes, I also know better than to solder to batteries. While I've not read up on the latest LiPoly concerns, I'm mildly experienced as an electronics hobbyist.)

Example listing for power bank kit (mine is identical, but not from that listing) --> https://www.ebay.com/itm/183897827870

It appears Geekworm has released their RPi4B supported UPS HAT

https://geekworm.com/products/raspberry-pi-ups-hat-2

It also mentioned the I2C power off function, does anyone on here have tried?

@jbaumann have you considere altering the design and avoid dependence on another charger circuit,
and rely instead on super-capacotors?
(something along the lines of https://juice4halt.com/)

Dear Joachim,

Which is the correct board version for us? In the Wiki you mention only Attiny 25/45/85, but there are multiple options. The most obvious is Attiny 25/45/85 but it is No bootloader version and we upload bootloader in the next step. I am a little bit confused here.

Hi

I can't see from your documentation where the wires from the modified board are connected to or where exactly the Dupont connector attaches.

Could you provide images of the final layout?

Hi Joachim,

thanks for the elaborated design and DIY explanations for the RasPi UPS HAT!

Sadly I cannot get the firmware for the AtTiny to compile since there is missing code as stated above (Wire.onInterrupt(disable_watchdog)).
How to fix or circumvent this?
Thanks!

Harald

Hi,
I am intent on implementing this device on my RPi, but am getting the following errors in the Arduino IDE:

Can you suggest where I went wrong - these error messages might as well be in greek:(

Thanks

Hi, I am developing a portable pi UMPC/sidekick. I want to add your solution there and forget about developing one from ground.
So i need Help of yours to get things right.

1. i will use a existing battery charging breakout board to charge the battery. this one
2. so can i use the the ups part form your project to power off the system from raspberry pi and a button to boot the pi?
3. i want to see the battery details in with regular way like you can see the laptop battery details in app like xfce-battery or lxqt-battery plugin for panel . Or a terminal way is ok.

Please help me out
Here is my project.
