Raspberry Pi cases

There are different cases available for the Raspberry Pi. The 'official' case from the Raspberry Pi foundation is on of the nicest one I know; it fits the Raspberry board and with the side being removable you also have the option to expose the GPIO pins to the outside world.

But most of the time you don't want to expose the GPIO pins to the outside world, you just want to use them on an extension being used.

LoRa case

This is a special case for the Raspberry Pi LoRa gateway board developed by LinkLabs.
It is based on the case for the HiFiBerry+ board. The design is only changed to allow it to be laser-cut in 3mm plexiglas and the holes are changed to match the antenna connector positions.

This is not a full product case, just something to use when developing the software. It gives access to all Raspberry Pi connectors and the micro-SD card while still giving enough protection for the electronics when being used. A final gateway needs a sturdy case with everything embedded in the case.
I use this case for my development gateway that I have on my desk.

Thermostat / Home Automation case

I needed a case for the Raspberry Pi board with an extra relais board being available to control a central heating system. The system uses a digital on/off control. A version for OpenTherm will be made in a later phase of the project.

I actually needed two different systems: one being placed in a separate office with a convection unit and one in the overall room (the shop). The main unit in the shop controls the central heating boiler and the main ventilation system, the unit placed in the office only controls the fan in the convection unit. It communicates with the other Pi over the wireless network.

I bought the case from TinyTronics, it measures 115x90x55mm and has holes for mounting a base-plate in the case. The base plate was laser-cut from 3mm plexiglas and it took me a few tries to get the position of the mounting holes right.

The relay board (also from TinyTronics) has either 2 or 4 relais. The 4 relay board fits right over the Raspberry Pi but the 2 relay version needs a small frame so the same mounting holes can be used. A small bracket was 3D printed to make this possible. Also the 5mm spacers have been 3D printer, I only had 10mm spacers and printing a few short spacers is less work than cutting the 10mm ones down to 5mm

Raspberry Pi case

The base plate that I made for the thermostat has two mounting positions for the Raspberry Pi. With a few holes in the case, the USB and Ethernet connectors are now exposed.
Other connectors like power, HDMI and the micro-SD slot are not accessible from the outside. That's okay though, since this case is meant to be used for embedded projects that do not need a monitor.

The photo shows a data acquisition board mounted on top of the Raspberry Pi to create a data logger.  This is not yet a final project but I decided to create a case for it now I am adapting the standard box I bought.
