Thank you very much, I built it according to this guide:
https://synthnitz.blogspot.com/2019/...ght-guide.html

I also got my display from "Buydisplay.com"

But I found that the lighting was too bright and I disconnected/cut the 5v power supply of the display and soldered in an 820R ohm resistor, 510R to 1K is very good to get a good light! I also increased the 56R Ohm resistor to 450R Ohm to increase the contrast, so the dark blocks in the display have disappeared and the writing is clearer! The 56R Ohm resistor is on the circuit board where "CONT" is written, CONT stands for contrast, there are two resistors next to each other, the 56 Ohm and one 18K resistor! See also wiring diagram. I got this idea from another forum, there is also a manual for it, but the one there installs a "winstar display" but the changes can of course also be made for this display. Everything is great for me! thanks
