PCB Manufacture
The printed circuit has been drawn. It will be the same shape and dimensions as the original PCB. The hole in the center will allow the passage of the ball joint, while the cross, also in the center, will serve as a passage for the enamelled wires of the coils.
Then comes the engraving (in the English style), on my CNC table.
Now it's time to solder the components. IC supports have been provided.
Once tested, the circuit was protected by painting with an acrylic tropicalization varnish.
Once the box has been drilled and milled to accommodate the USB socket and the 5.5 x 2.1 DC plug for 12 Volts, it was installed in the active optics. The USB power supply works well, so the external 5 Volt power supply was not necessary. This is good, because there is a real lack of space!
The USB cord was stripped and rolled in Chatterton due to too much rigidity, which would have strained the USB socket of the UART.
