Now the project is taking shape, there is a need to house:
- a Raspberry Pi B+
- some additional electronics (5V converter, transistors, ...),
- the 433Mhz receiver + digispark
- a LCD Screen (4*20)
- 4 pushbuttons
- the AirPi at the back
- additional SD Card reader (or even USB hard drive)
- Z-Wave USB-Key
So far, the best potential solution I found would be a nice wooden box like this:
Having vague memories from my University years and the concept of adiabatic enclosure, notions of heat and the First Law of thermodynamics, I am also trying to work out if vents will be mandatory or not.
The Raspberry model B+ seems a lot cooler than my old B (CPU is around 10°C cooler). I added a DS18B20 temperature sensor to monitor the temperature inside the wooden box and it is about 6-7°C more than that outside the box.
According to Raspberry Pi Engineer Gert van Loo heat should not be a problem, but I'm trying to keep the temperature as low as I can.
