Who builds it
I'm Zen, and I build Zen Circuit Lab by myself: the simulator, every lesson and course, the solar and house-wiring tools, and the fixes when something is wrong. I wanted a real bench that any student, hobbyist or technician can use, whatever they can afford, so the lab stays free.
It is not free to keep running, and every new lesson takes many evenings. If the lab helped you learn something, pass an exam or finish a build, a donation of any size keeps it free and growing for the next person.

Other ways to help
- Share the lab with a class, a study group or a fellow technician. Most people find it through someone who used it.
- Tell me when something is wrong: a reading that looks off, a lesson that confuses, a part you need.
- In the Philippines, the bill of materials can show Shopee and Lazada links for the parts. If you buy through them, the shop pays the lab a small commission. You pay the same price.
