First, I want to build an auto-roller for thermal printed labels. It’s a long story where I, due to my sense of discretion, must be vague. I’m thinking an Arduino, probably swapped with a smaller sibling after proof of concept. Add a small servo or stepper motor, dowel with a slot to put the head into, a start-stop switch, and a contact switch to tell it to advance. I might need to look at tensioners but still, better than the current setup.
Secondly, an immersion cooler. I watched the Brewing TV episodes with Wil Wheaton, and I knew I waited a lot of water when I need but watching them talk about it to was revealing. I guess that beer making can be bad as 20 gallons or something of water to a gallon of beer. I don’t think I was that bad, but still, even five to one isn’t chill.
So, immersion chiller. Copper coils of pipe circulating cold water, but what then. I’m thinking of building a (Derp… little pump thing, no contact with liquid…) pump to circulate the water in a closed loop, on the opposite side of the system from the beer, use a peltier element with all my heat sinks I have from scavenging. For proof of concept, I could skip the pump and just manually do it with a bucket… I do need () pumps anyway though for other projects. Whatever.
Oh yeah. I also want to build a mostly scavenged cold coffee thing. Make had a write-up from Instructables on one that was hilariously over done. Why the () do I need to buy laboratory grade glass or carefully cut and sharpen copper pipe. The only two things I need to buy are two stopcocks. Maybe a bit of rubber.
Peter's stuff.
