Nice form factor, would be cool if it worked as advertised

Shipping to the US went about as well as can be expected. No complaints there.

My unit does not work with any of the USB-C power supplies I have; a short time after booting, the yellow LED starts blinking, indicating that the device has detected a voltage sag. According to the hackaday blog posts, this is basically due to the fact that you need an ultra-stiff power supply for this thing to work correctly. I will try the official Raspberry Pi power supply as recommended in the blog documentation, but my hopes are not high.

The form factor is good. I did have to put a spacer on the rpi header to give the UPS some vertical clearance; this is due to the fact that I already had some aluminum heatsinks glued onto the pi itself, and did not want to remove them. I think if I didn't have the heatsinks it would mate perfectly right out of the box.

TL;DR this is not a plug-and-play solution; you probably need to order a very specific power supply to ensure that this works.

Dear Patric,
many sections of the documentation indicate that, according to measurements, successful use is only possible with the official pi power supply.
There might be others on the market that work but from your description of the failure it is definitely a power supply issue.
I'd be interested which brands of PSU you already tested and which voltage/power rating they have. Don't forget also the cable has an impact in case you were using a PSU with USB-A connector and an adapter cable.
Regards,
Dirk
