Here the flask is shown as it was used in my first real science fair project in 1992. The flask was evacuated to maybe 5-10Torr and backfilled with He. In the center of the flask is an electrode which was connected to a tesla coil. The resulting discharge was beautiful. I won first place in my city science fair!
Flask shown in its gimbal-mount frame. Since the flask is suspended from axles 1" above the center of mass, the flask self-rights in the frame. The frame is made of 80/20 extrustions, and the hardware was less than $200. The MDF was left over from another project.
The flask is tilted a bit to show the function of the axle bolts. When released, the flask simply rotates (oscillates) back and forth settling at vertical after maybe 4-5 rotations. The bronze bushings are remarkably low friction.
Since any brewer worth his salt must have temperature contol over the fermentation process (especially if he wants to make any Lager or Pilsner type beers), I decided to add temperature control. I started with a Wine Cooler which was on sale locally. It has thermostatic control, and a nice little Peltier thermoelectric cooler with fans. Perfect! I dismantled it to salvage the power supply, cooler, etc.
Here's the wine chiller guts, mounted on the side of the fermenter. It's set to 65 degrees here, and maintains its original control range, 55F to 70F. It even still has the little light functionality. The light now illuminates the brewing beer.
Here's the pour after the first fermentation stage. The beer was racked (see figure 9, then transferred to a temporary vessel. The wide, round bottom of the boiling flask actuall performed perfectly for collecting the trub, and was extremely easy to rack. Keeping the racking cane above the level of crud was very easy. The white sudsy nature of the trub comes from me spraying water into the flask first to loosen the trub from the flask bottom. The sides were easily cleaned of any remaining hop residue with a quick spray down. Here's a quick video of the spraydown through the bottom view port.
