When life gets me stressed, I think about something important. In this case, it’s brewing.
The gas alcohol sensor can pull down 750mA at 5v, so not even an Arduino can power that sucker directly. I think I’ll get my atmospheric sensor running on the Thing, and fight with the alcohol sensor another day. The power won’t be too hard, basically I just need to make a power supply for both, ideally running off the same wall wart. Then it’s just a matter of chopping down the output from the sensor, probably using a voltage divider. Hell, I don’t even know if I’ll get meaningful data. I’m looking at alcohol, as a gas, in minor concentrations. Do I need this?
Now I’m at a bar. I feel good. I’ve had three cocktails and I’m working on a black lager.
My current thought is about variations on brewing. What can I do to make beer better?
My current thought is about how to add a certain magic. What about adding apple caramel (and yeast) to make the perfect hybrid.
