I used to print circuits directly plaque edinger with the stylus on the drawing would have made after the copy paper began using printed circuit copy of the Remove the paper plaque insert with pencil pushing copies passes over I print plaque after they were uttered edinger and goes through what I’ve been trying am I 🙂 hey go hey
This of introduction Ramada similar but slightly more practical as you can before the printed circuit on a paper transferred Want drawing you want from the printer after the paper copper plaque placed tape fixed with the hammer and the nail prints in the circuit hole (pad) segments is nailed after edinger the drawing is being made hole locations are announced for the paper looking a little easier to draw a different method
this combination is not used in practice nails had a different name but the same thing but forgot to indigo

Adjustable Regulator Module LM317T Circuit
Compensated regulator IC LM317T LM317T adjustable positive voltage regulator IC Module PCB drawing pcb printed circuit board size is quite small for the modules that you can use to adjust voltage potentiometer connected by cable LM317T pcb on the part of the bridge rectifier diodes (1N4007 can be used 4) the filter capacitor (1000uF) and so on. is sufficient to connect only the output of the transformer dc sources (pc power supply, dcadaptör, etc.). chart the way you want to use no need to use 1000F capacitor 1000uF and 100uF 25v output that give you the highest voltage level to enable an integrated use of all the capacitors voltage is adjustable from 1.2V 32V must be at least 35V
