I’m now set up for kegging beer, and am putting a brown ale into a keg. I want to hurry things along. Kegging usually takes 1-2 weeks, but I want the beer ready in 5 days. To speed things along, I’m doubling the pressure to 20 psi for the first two days, lowing the temperature, and shaking the keg a few times a day. After the first two days, I’ll reduce pressure to 10 psi. If I shake it after that and CO2 still goes in, I haven’t over carbonated. I’ll bring the temperature up to 38F the last day.
Here are instructions I found:

Cold and a long tap line help reduce foaming.

Have the time displayed by colored liquids in glass tubes, either a column of liquid or a large segment. The time tube can be straight or circular.
Move the liquid by a mechanism where brass gears compress a bellows. The brass mechanism would be driven by a microcontroller.

The motors made for RC planes and cars are high speed and high power.
For example, the Turnigy Trackstar 1/10 12.0T 3300KV Brushless Motor, $23 specs are:
Kv: 3300
Max Voltage: 15v
Max current: 35amps
Watts: 550
Resistance: 0.0221Ohms
Max RPM: 50000
The load on a microfuge will be greater–22 tubes x 1.5 ml can be roughly 44g, figure a 100g total load with the rotor. So slower than max, but still quite fast.
High power ESC modules are sold to run these motors. So they take DC power, and a servo like signal (PWM), +5, GRD.
So a 10k RPM microfuge can be made with one of these motors + ESC, a servo for locking the lid, and a microcontroller to run it, take speed / time settings, and monitor and show the RPMs on a display.
Power could be from a PC power supply or a dedicated supply.
