By combining 49 of them he’s put together a soda bicarb diode steering circuit for a 7-segment display capable of showing the digits 0 to 9.

3. Diode bridge test schematic for Case 1. The inductors provide dc isolation, with a coupling coefficient of 1. Diodes D1, D2, D3, and D4 are identical, modeled with a zero-bias junction ...

The value of R1 is determined by the maximum laser current required (in this case, 250 mA), adjusted by the laser diode's typical forward voltage of 2.0 V as given on the datasheet. Solving for R1 ...

R 1 ‘s voltage drop limits the zener diode’s voltage value that the circuit measures. If R 1 ‘s value is 1Ω, then the voltage drop across it is insignificant and, in millivolts, is equal to the zener ...

The circuit is simple enough: it uses a capacitor, a resistor, and a pair of diodes (one of them a zener diode). He uses this basic circuit to drive simple regulators with input and output filter ...

The circuit uses commonly available parts. Diode D1 and MOSFET should be selected to carry the full current and have a total voltage drop less than the reference voltage at the maximum current.
