To be honest, I haven't touched a circuit board in about 20 years, but I went slowly, following the excellent instructions and after about 5 hours it was finished. Worked first time!
Excellent kit, captivating to watch and watch, and watch… Easy to program and just a really nice touch of history. It gives that 'warm glow' as it were.
The kit is good build quality and I also purchased the black finned case at the same time. A decision that I most certainly do not regret.
The finished clock is very nice and a credit to the designer.
