Thinking of a new gadget...

[Csory_imp]

A few more things based on your PM-ed questions:

- The unit (both display and brain module) is waterproof. This is achieved via casting in epoxy resin. The rotary encoder assembly (connected and used only while you configure the unit) is non-waterproof.

- Theoretically, the firmware could be updated later using the rotary encoder connector (also acts as an ISP programming header). To do so you'd need a Mac or a PC and an ISP programmer (and some familiarity with electronics and computers.)

- Connector cable between the display and brain module will be cut to measure, i.e. you can let me know the required length. Max length is about 20in or 0.5m, due to data speed constraints. Should be kept at minimum. The cable itself is ultra-flexible black silicone ribbon.

- Main wiring is made of a 4-wire black fuel/oil resistant data cable.

What comes now (before building the first unit...):

- Will make an "installation manual", and an "instruction manual" in pdf, public.

- Will post a detailed update on the latest version (so that you can clearly see what the final iteration looks/feels).

- Will do a complete video on making a unit to help with understanding "what's inside".
