I completed a second version of the artwork using KiCAD and from that artwork made the pcb for the el-load. Looking at the pictures below, in the first one you can see the exposure lamp, artwork, and photo-sensitive printed circuit board (pcb). The pcb is exposed to the light for 6 minutes using the timer show in the right side of the unit. The next picture shows the board placed in a glass tray with a photo developer and then rocked back and forth for approximately 3 minutes to remove the exposed resist. The next picture shows the developed board ready for etching. The next picture shows the ferric chloride solution used to remove the exposed copper from the board. The final picture shows the etched board before the resist is removed, sheared to size and drilled. This system is a positive photo-fabrication process and the total time from start to finish is under 20 minutes. More to come.... John
