The acrylic is a bit thick so allows for this quite well on a tightly woven fabric. When just using water, or using acrylic paint that is diluted a little bit more, its nice to paint by making paint strokes with a brush. The creases of the cling film also left interesting marks on the swatch I painted with heavily diluted yellow acrylic paint. It could be nice to do these measurements a bit more precisely, but for now this will have to do....Still have many circuits to make this week. @@ -178,7 +180,7 @@ We have a box of transistors here but I found out it's a mix of Voltage Regulato I added a 1N4007 diode (1000V-1A) for safety in case I want to use it with motors etc at a later stage.
