I've gave the machinists the plans today, and sweetened the deal slightly with the currency of industry: beer.
They're fairly fascinated with the whole TEC thing after I explained it to them, being what they are, how they work, and roughly what they can and can't do. So they're making up the chiller device (which incidentally will weigh about 700g or about 1.5lbs fully assembled), and I'll bring in a small esky (cooler box) with a 6-pack of room-temperature beer, my lab bench PSU, the two TEC's, two 12v pumps, some tubing and a shrouded radiator with fans. Will stick the beers in the esky, add in about 3 litres of water (just enough to mostly submerse the beers in water), and use the esky as the reservoir for the cold-side loop, and plumb up the hot-side loop through the radiator, and see what can be achieved. The challenge is to achieve ice-cold beers in 30 minutes as a measure of success.
If it works, we'll celebrate over a cold beer.
If it doesn't, the beers go into the fridge for another day and we all go home disappointed.
