Can’t say this house is cheap, but the quality is in top, and it got plenty of room inside for other sensors, or even the power supply for the pi.
Mounting the pi
Inside the house you will find a metal plate with a plastic piece, looking a bit like a camera. After removing that piece of plastic I drilled two holes and mounted the pi with two bolts, held apart from the metal plate by two 5mm nylon washers.
To hold the camera I 3d printed a mount, but you can most likely be able to modify the dummy piece of plastic too to hold it instead.
If you want to print your own mount, you can generate your own stl file using OpenSCAD and this little script
You can tweak it by changing the parameters in the top of it, but it should be fine as it is.
The final version of the camera panel got a big larger to fill the entire window in the front of the house, plus I printed it in gray to be a bit less visible, and at the same time this also helps shielding the led from the camera’s lens, so even in total dark the red led can not be seen on the picture. (if you don’t want the led to be visible at all, set ledVisible to false in the script above.)
The power supply is a dirt cheap version I found on eBay, it costs less than $6 and is with free shipping from china. The specs on the power supply is 2A at 5V, and while having it connected to the Raspberry Pi with everything running, I could measure the voltage to 4,98V. It’s not perfect, but seems to be plenty close to have it all running stable. Power supply can be found here: http://www.ebay.co.uk/itm/151156859870
Notice, with this power supply no wires are connected, and you need to solder some on yourself. To connect the power supply to my Raspberry Pi, I decided to power it through the GPIO pins, instead of soldering a wire on with a USB connector, and then plug that connector into the pi. If you want to do the same, you must be sure what pin is for what.
On the top right row (pin 2), you can see the label 5V. This is where you can connect the positive 5V wire. Two below (pin 6) you find GROUND, this is where you connect the negative wire. What is just as important, is to know where pin 1 is, so if you have a look at the raspberry pi to the right of the GPIO pinout, you can find P1 marked on the silkscreen, this is pin 1.
This is the first time I have the camera outside my house, still under roof though. While testing wifi signal strength, I took a few more pictures of the “final” (what project is ever REALLY done?) result. I still think I should print the camera plate in black to make it even more neutral to look at, but that is about it too. The over all look seems professional, thanks to the top quality dummy house.
Even the wire carrying mains power to the power supply inside goes into the case through a good looking fitting with a rubber seal, which will also work as a wire strain relief.
