Here is a simple schematic circuit (with parts list):
Here is the physical layout of the main components from their datasheet:
Here is the breadbording (simulating logic input with a temporary switch):
Here is the realization schema on a stripboard:
And here is the board:
Probably the heat sink is useless, due to the typical current flow in the electric bolt (only very few seconds maximum, during unlocking), evenf if I plan to use it to contemporarily unlock a set of electric bolts on a large port (for enhanced security). By the way, it was laying around after some salvaging from old electronics...
Now my RFID Electric Bolt is completed.
