I am really enjoying building the Aion projects, I think this is build number 6 The projects are well thought out and the documentation fantastic.
This is my second Aurora, the first did not work and after several days of tracing figured it was a counterfeit CA3080E. I ordered a new PCB and got the real IC from SmallBear and proceeded to build one that does work. Really happy with it. I changed C1 to 150 pf, mainly because i had it in stock and after reading the build docs sounded like the right choice.
I noticed the silkscreen was corrected on the pcb
the build doc may need an update to note this 🙂
I used water slide decals which I still challenging but am getting better at it
Really happy with the sound of the compressor
Modifications or part substitutions
