A little case that holds a mini digital voltmeter and a 1-17V adjustable voltage regulator.
Wire it up so the voltmeter reads from the input voltage and you can monitor your source battery voltage.
There are two sets of files:
3.15mm to 3.15mm: Designed to have a shielded 3.15mm shielded cable wire on both the input and output
2x 18AWG to 3.15mm: Designed to have two 18AWG wires on the input, and a shielded 3.15mm diameter cable on the output.
Instructions:
Solder your assembly together as pictured.
Adjust the potentiometer on the voltmeter to it reads true input voltage
Adjust the potentiometer on the regulator to your desired voltage
Pop the regulator into the bottom half and the voltmeter into the top half
Apply a gratuitous amount of hot glue to both sides, even around the wires
Press the halves together and hold them for 30 seconds
