Both panels are done using a CO2 Laser.
Black on silver needs Cermark (since the laser marks on anodized aluminium are always white).
I use a Chinese model bought on eBay (50W, 50cm x 30cm workspace).
Volker, your panels look fantastic. How do you drill them out after etching? Does the laser leave enough of a guide divot that you can reliably drill by hand?
