Time to order another production batch of PiHouses - we have broken the 250 barrier!
The margin from PiHouse sales is going towards our Project Bakewell and there is a photo of the prototype controller board on http://www.thepishop.org/bakewell.htm. Nik Staunton of http://www.lyteral.com did the board design for us. Notice the four large mounting holes in the corners <g>
One PiHouse user asked why the PiHouse slot for a ribbon cable to the GPIO port was slightly offset (see the photos on http://www.thepishop.org/pihouse.htm). The answer is simple.
Finding support location points on the Pi (in the absence of mounting holes) is hard. The only real place at the SD card end was just inside the GPIO connector. So, moving the GPIO slot very slightly outwards allowed space for a support. It still leaves bags of room for a ribbon cable to come out.
