Re: Newly acquired FRG7 Loop light stuck on/loop not locking
I suspect cracked solder joints based on age and the works sometimes. Clean and flux the board, reflow with a hot air gun and I'll bet it's fixed. Then yuo can proceed with the alignment

Re: Newly acquired FRG7 Loop light stuck on/loop not locking

Re: Digital readout
Pentagrid, thank you for your nice idea. I will have a look at it. That would be a nice upgrade for version 2.0. I'm also busy making the readout complete wireless, using 2 times the ESP8266 or ESP32.

Hello Ted, Someone else posted the link already. Thank you for that. I’ve checked it on ebay.co.uk and there you can find it. So yes, I do ship it worldwide. UK should not be any problem.
