Okay, electronics do work. i was blindly following the image of the board, rather than schematics. My PNP and NPN were not placed correctly but now it finally works. At first i was quite worried that EL panel was way too dim but after testing it, its working quite well. Next part is to print out the EL panel holder/cover for my 150P Newtonian. This is such a nice project and huge thanks to the maker Nathan who has been quite helpful and active in quick replies. Without him i would be stuck hehe....

Yeah, i did everything according to schematics with brand new components -no luck. ive recreated just the flat panel portion on protoboard. Still wont turn EL panel on. i have power at the little box for the EL panel regardless of what app is saying whether its on or off...

Hey Nathan, i have not been able to resolve it yet. I did not know that i wouod need that small box DC-AC converter as well in the mix. So ive looked at the schematics in the manual and from what ive gathered while watching youtube videos on NPN and PNP, it seems that you have switched them up or at least labled them up wrongly in the image of your board, where you have servo and EL panel electronics devided by the color. First NPN should be closer to the EL panel plug. I did that. ive switched PNP...

I have managed to get the servo motor to work. LM1084IT-ADJ was wired wrong. NPN transistor was also wired wrong and i hoped that would solve my problems but nope. Still cant get EL panel to light up. I checked the wires leading from the board and they are live, all the time but EL panel doesnt want to light up. I am missing something here. i checked the EL panel itself by wiring it back to its little (buzzing while turned on) power transformer which came with the EL panel. I dont know if EL panel...

Makes sense. In all previous projects, arduino would light up when power is connected even though it has not been plugged into pc. is the first big diode connected in the right direction?

Thank you for replying. You are correct, i did not provide much details. Here are the images of my board. I switched arduino position because i wanted to be able to plug usb directly inside the box. When i connect only 12v power, arduino does not light up, it only lights up when i ppug it into the pc. When i connect usb to pc, EL panel to the appropriate cable and servo motor to its plug and open the app, i am able to connect the app to the device, or so i think because there is no error message...

Hello, i am sorry if this is not the right thrrad to ask my question. i have followed instructions, soldered everything togather. When i connect arduino via usb to my pc i am able to upload the sketch to it but when i try to use the cover/panel via app nothing works, nothing is happening. Now i will admit, i did not cut my usb cable, i did not see enough images nor explanations about that and i figured i already have usb cable from my arduino to pc. now that might be where issue lies, i dont know....
