The fan along with the aluminum tube and "heater resistors" doesn't seem like it
would be in feedback control, does it... More like the fan dominates and the whole
collection of sleeves stays at room temp.

The fan has magnets added and 1/8" laser cut acrylic pieces added though, so maybe
it doesn't move much air. There is a mention of, "verify that the two small 2-56 holes on the aluminum sleeve align with the
holes on the heating resistor.", so the heating resistor must be a real heater bolted on with heat transfer paste.
This description is not complete it seems -- no bill of materials listing that special heater resistor.
It seems more like something that will work after noticing these details. Odd that fasteners are in inch sizes
as if it was designed with screws from some organizer drawers that were filled up in the 80's.

I guess the hardware is easy to improve on. I like their code concept and am curious to hear more about the fluidic
system. I bet Wong has more to say on it now -- we need to ask him.
