DIY 12 Volt DC to Five Volt DC 27 Ohm Resistors
- 1). Cut four lengths of wire, with each length being at least six inches long. Strip 1/2-inch of insulation from the ends of each wire segment.
- 2). Twist one end of the first wire together jointly with one end of the second wire and with one of the leads from the first resistor. Crimp a ring terminal to the free end of the second wire.
- 3). Twist together the loose lead from the first resistor together with one of the leads from the second resistor. Continue doing this for subsequent resistors until the fourth resistor is twisted onto one of the leads from the fifth resistor.
- 4). Twist the remaining lead from the fifth resistor together jointly with one of the leads from the sixth resistor, and with one end of the third wire. Crimp a ring terminal to the loose end of the third wire.
- 5). Starting with the sixth resistor, twist each loose lead with the lead from the next resistor. For example, twist together the loose lead from the sixth resistor together with one of the leads from the seventh resistor. Once you have twisted the lead from the eleventh resistor to the leads of the twelfth resistor, twist together the loose lead from the twelfth resistor to one end of the fourth wire.
- 6). Attach the free end of the fourth wire to the positive battery terminal. Attach the free end of the first wire to the negative battery terminal. To use the 5-volt power supply, connect the ring terminal at the end of the third wire to the positive terminal on the output device, and connect the ring terminal at the end of the second wire to the negative terminal on the output device.
