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. He takes the idea for his diode from electrolytic ...

could be used to replace both the rectifiers and transistors necessary to connect long distance phone calls. In essence, the four-layer diode was the first integrated circuit since it did the work ...

To the left is a schematic of a full-wave rectifier ... Because of this I’ve used 1N4001 diodes to make the bridge rectifier. Bridge rectifiers are also known as full-wave rectifiers because ...
