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.

Two of these were diode types. More examples of Williams VFC designs incorporating diode pumps are detailed in his fascinating (and entertaining!) narrative of his creative design process: “ The Zoo ...

Although Fig. 2 is a simple circuit, it has the disadvantage of high forward voltage (V F) when the diode conducts. For example, the typical V F of a Schottky diode is ~0.4V and can result in ...

The best part about post-mortem teardowns of electronics is when you discover some unusual design features, whether or not these are related to the original fault. In the case of a recent ...
