200 x 200 mm) Everyone of the ~42,300 transistors were hand-soldered to one of the massive PCBs, which look more like interactive circuit diagrams than actual circuit boards. This incredible ...

at the transistor’s input. You’ll hear the resulting output through the speaker. 1. Assemble the circuit shown in the diagram. You may choose to solder or use common IC Experimenter boards.

When the germanium heated up -- a natural outcome of being part of an electrical circuit -- the transistor would have too many free electrons. Since a transistor only works because it has a ...

[Joe Wingbermuehle] has an interest in computers-of-old, and some past experience of building computers on perfboard from discrete transistors, so this next project, Q2, is a complete ...

The development board and the circuit board with the potentiometer from the Raspberry Pi Pico Experimenting Kit from Elektor ...
