Well I reckon I'm becoming the Ozzie version of Electro-Boom the otherday when I got up at lunchtime I decided to check if that first LCD was still good and instead heard a nice loud bang as the diode on the nano went to magic smoke heaven, so programmed a new nano and found the 7805 on the brainboard was very hot so turned everything off. So replaced the 7805 on the brainboard and set it all up again only to find the 12-12 chip was getting toasty. So went and finished off the other MPPT board and connected it all up and only get the startup screen on the lcd checked between D4 on the nano and D4 on the LCD nano and got continuity. So not really sure just what in the hell is going on and that $300 50 amp MPPT at the 12 volt shop is looking better by the day. Now when hooking up the main Nano in the Arduino suite on my linux laptop it does show the nano is programmed as I can get to the setup screen. Trying with the win10 laptop well can't even get it to see the nano so just stayed with the linux one and after every change it does refresh the screen with the changes. Then this old laptop running linux decides it will disconnect and still stuck on first base. Edit: Well checking with my clamp meter when the sun does come out this second unit is working or atleast putting current into the batteries so I'll just leave it running.
