I received the new PCBs for the single character; I also built an automatic coil winder to speed up the process, even if the design of the coil still needs improvements; Actually the pin mechanism is more similar to a coil gun than to a standard electromagnet, since we have a coil and the magnetic "bullet" travelling inside; the placement and number of turns of the coil is the most critical part.
