Small, focused builds can make core engineering ideas more approachable. They encourage learners to move between diagrams, component specifications, PCB layout, and testing, the same skills used in larger prototyping projects. A CMOS logic-gate PCB can serve as a starting point for studying digital design or as a building block in a broader electronics experiment.

Beyond the technical satisfaction, the finished product is genuinely useful. Imagine controlling your desk lamp, bedside light, or workshop illumination without getting up or fumbling for a switch.

Count the seconds - every second counts with this CMOS-based clock

Compact creation some 51 times smaller in footprint and with a 10,000x reduction in latency over traditional CMOS equivalents.

Harry Axten’s CMOS Clock doesn’t contain a single microcontroller chip.
