Assembled my E-field kit.

Just done soldering... that's a lot of joints
@Egon Wanke The package arrived here yesterday and all looks fine
Now it's time for some PVC tubing

Bdw are those boards acetone proof? for cleaning the solder side?

Try it on a small area first, however Acetone would not be my first choice, it is rather too agressive, you will probably melt the LED's and take the markings off the resistors and capacitors along with the silk screen markings on the board if you are not careful.
Get some proper PCB cleaner, or failing that some isopropyl alcohol (your local chemist can probably supply it) or even methylated spirits.
