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

Gebruik versie 2018-10-05 van de klok software (zie ergen hierboven bij de updates). De oude versie kreeg ik met geen mogelijkheid aan de praat. De nieuwe dus wel. Daarna bleek dat de drukknop van mijn knop niet goed werkte. Na vervanging werkten de instructiesclock set selectadjust 1 clock set adjust 1 + 01 00 00 clock set adjust 2 + 02 00 00 clock set showdate yes goed. Knop ingedrukt houden je ziet op een gegeven moment op het meest rechtse display achter elkaar de nrs 1 - 4 verschijnen.
