I banded together with a few other designers to create a digital clock mainly made out of transistors. We wanted to expand our skill set and be able to troubleshoot any problems that may come up in installation design. This digital clock is made entirely of transistors, resistors, diodes, and capacitors – no integrated circuits. Through this process, I learned how to solder surface mount boards, read and write a schematic, discrete transistor-diode logic, basic circuit theory, and a mental framework for debugging electrical problems.
The design is based on this transistor clock project.
