The Transistor Clock is a behemoth wall-mounted clock kit that uses only transistors, resistors, diodes and capacitors for its logic, rather than an integrated circuit. It comes with 194 transistors, 566 diodes, 400 resistors, 87 capacitors and a printed circut board that shows you what needs to be soldered where.
This is an electronic kit for the experienced hobbyist.
The result is a wall hanging clock that shows 1250+ parts in all their glory.
There are no Integrated Circuits, all functionality is achieved using discrete transistor-diode logic.
The assembly manual has a logic tutorial and the circuit descriptions and attempts to explain how the clock works.
The kit comes with all parts and the PC board with the part symbols showing the values of the components for easy assembly. Solder and solder-wick (we all make mistakes) are included, along with spare parts for most items. All you need is a soldering iron, some basic soldering skills, and a few tools.
