Hi madsolute!

Thanks for the link. I am a DIY tinkerer myself, continually being amused with some or another aspect of physics, electronics, photography, and such. So, naturally, I bookmarked the home page of after looking at the LEGO film development system you referenced above.

I had a black and white and color darkroom for many years, but I never developed film with a machine. So, everything was manual in operation.  While automatic processes have advantages such as consistency and perfect timing and sequencing, they may have limitations too.

I reflect upon some of the things I did, and which I wonder how a machine could approximate them. For example, I used to invert and rotate the film tank as I turned it during development. I remember tapping the tank against the work surface to cause bubbles to dislodge from the film (to prevent the appearance of pinholes in the film). I guess there are automatic procedures to address such things, but I am left in wonderment of whatever they are.

I like the idea of the beverage heater for temperature stabilization.  It set my mind to turning about how one might take a thermistor, a comparator, and that heater to hold water at a precise temperature.  In my darkroom this was accomplished with thermostatically controlled mixing valves, blending water from a hot and a cold water line.

Thanks for sharing and for stirring up all those old memories too.
