Kit is too easy!
I assembled the kit. Instructions are fine!
Small components are added first. Larges compontents (caps/relay) are added last.
Might use 250k pots and 100mf caps for longer
duty cycle...Good kit!! KD5BIH

Reliable circuit
I used this timer to cycle a small 12v water pump for six hours a day last summer. I built another similar device for this summer and so far this new timer is working flawlessly.

A Great Kit
Good circuit, but I replaced both pots with 250K units, and replaced both 100mfd caps with 220mfd ones. This give it a nice 2-60 second timing cycles, and with both 250K pots it can be adjusted for any ratio of duty-cycle.

Good circuit and easy to assemble.
Circuit worked exactly as advertised and the assembly instructions were easy to understand. Kit went together extremely well.
