Sorry for the terrible lighting. The design of the escape wheel is the only thing I copied from the internet, the rest was all designed by me. It has a print in place ratchet mechanism to set it up. After that test I added some weight in the proper compartments and it got much more stable. It gets to 70 seconds approx. Id like to increase that range though. I'll be finishing some details and posting the design for a couple of bucks soon.
