Individual electronic control circuits ''(e.g. resulting from use of the [http://www.dtonline.org/apps/pcb/app?1&0&1&0&0&0&0 '''DT Online PCB Designer'''])'' can be made using '''[[Photo-Etching]]''' or by cutting away material from a '''Copper-Clad''' board using a '''[[Milling Machine|CNC Milling Machine]]''' or '''[[CNC Engraving|CNC Engraver]]''' for example. Components are added by drilling small holes through the board and soldering them into place. This is known as [https://en.wikipedia.org/wiki/Printed_circuit_board#Through-hole_technology '''Through Hole Technology'''] ''(as opposed to [https://en.wikipedia.org/wiki/Printed_circuit_board#Surface-mount_technology '''Surface-Mount'''])''.<br />
<br />
<br />
The component mounting holes can be drilled using a low-volt hand-held drill running at high speed and with a 1.5mm or 2mm diameter drill bit in the [https://en.wikipedia.org/wiki/Collet '''Collet Chuck''']. Such small drills can easily break and more precision is obtained if the drill is held in a stand ''(or a standard '''[[Drill Press]]''')'' is used. Care must be taken to let the drill do the work and not to force the drill into the PCB. It will help if the circuit board is first taped by its edges to a flat backing board of [https://en.wikipedia.org/wiki/Medium-density_fibreboard '''MDF'''] for example.<br />
