Hi,
I was constantly having problems with Fuels and DS1742 chips (L1 NVRAM & timekeeping). They became difficult to buy and I often received faulty pieces. The issue is that Fuel doesnt start if the chip is faulty or missing. Long story short, I finally found some time to build a compatible circuit that uses a replaceable battery.
So far it seems to be working, still need a few days to test it properly.
If you can think of any test cases or something else I could try, let me know.
If anyone is interested in getting oneI think I will be able to sell these for around 65 USD. The price of parts doubled over the last year so hopefully this trend will not continue. I think I can manage shiping for under 15 USD to US, a bit less to EU.
Hopefully it will prove reliable!
