If you have difficulties finding the 300VDC print relais Rainer used, here reichelt.de type Fujitsu FTR-K1 / 5V, rated 300VDC! You can use the FTR-F1 (2x2) 12V and 24V for the semiconductor adapter from their page too. And Rainer used Micromatch PCB connectors, also at Reichelt, type 374 is the PCB SMD female socket and 372 the flat ribbon male head. All not very expensive...

they had written in the offer other values on request, the order is out and it is paid, but they have changed the text now, I'm curious what happens!https://www.aliexpress.com/item/500W-toroidal-transformer-small-power-supply-transformer-220V-to-24V/32988120424.html

Hi, where did you order the Trafo in China? happy Easter!

@ Rainer Schuster which resolution does the software/display need, 800 * 480?happy easter

hi, try to stop, i think the company does not produce on the weekend! the *.bmp is for "diy self-etcher", there is no stop mask, in the double-sided is all right with me!? Yuri Vorobets has changed his sprint layouts to normal 2.54mm pins! I did that also with my eagle boards and changed a lot of others. I have additionally a 5V 3.5A supply for the raspberry and the display (step down converter and crowbar), everything pushed together and some components changed e.g. bridge rectifiers instead of single diodes. what i have not in stock at components i order for example at aliexpress. The transformer with an additional 8V winding I have just ordered too in China as toroidal transformer, 60USD including DHL shipping, let's see if that works!? happy easter
