Re: Pogo pins and 2x hat standard

Custom pins from Hong Kong arrived today. 8x pins bend the PCB slightly, so you probably can't use more than 20x at the same time. But other than that, these are perfect! http://move.rupy.se/file/pogo_pins_final.png Found 1mm bolts and nuts to clamp the PCBs in the middle if you need more pins: http...

Re: Aeon Alpha

With latest Raspbian and 3B+ gets you flawless experience on Raspberry with 33-34 FPS "smoothness" and thermal situation under control!

Only the text to speech is lagging a bit, but that's ok... Edit: on RPi 4 speech does not lag any more, seems out-of-order execution is really important for that?

Zero USB Ethernet

I have installed Raspbian on a Zero and successfully SSH:ed to it before but with the latest Raspbian it does not seem to work?

And yes I have written the ssh file in the right place and the ssh works fine on my RPi3.

Re: Pogo pins and 2x hat standard

This is the standard for Raspberry Pi and should probably exist in more lengths than 8mm. http://move.rupy.se/file/pogo4.png I'm going to give this a pause now and buy a better soldering iron, time usually solv...

Ok, these fit! Argh, no they don't work... since the top spring pin is same diameter as the bottom pin, it needs to be bigger! http://move.rupy.se/file/pogo.jpg Also the length came back wrong, you need to ignore the instructions and order as if PGTHXXX where XXX = C not A. So for me that means PGT...

Ok, it seems we're not getting anywhere with this.

Can someone at RPF/Broadcom that knows how to hook the features up give us an estimate of how non trivial that would be?

Anholt maybe?
