Got the new voltage regulator circuit board today and hooked it up. Set it at 5v and now the gekko is getting 4.89v from the Y cable. Now happily running at 310m after a couple of plug/unplugs

Congrats, sounds good

!
Can you share some pics of your setup?

I would but it seems to have thrown its toys out of the pram and now struggles to stay at 275m. Has anyone had better luck with it running off a raspi? Im considering getting one so I don't have my laptop on all the time. The only other mining gear I have is an old R-Box 100ghs. The raspi could do both I assume aslong as its got the externally powered hub for the gecko?
Mine have been running on a Pi 2-B since the first batch went on sale. Only played around with different PSU and hubs.
Only thing I do now is reboot the Pi about once a week and update it (which it's about time to do now).
