The wonderful people at Raspberry Pi were good enough to send me their latest piece of hardware, the Raspberry Pi High Resolution Camera, plus a couple of lenses. As well as taking a few landscape shots and just generally playing about with it, the first real project was to set it up as a High Quality webcam for video conference meetings.

Sometimes I’m a bit impatient, and this was a fairly straightforward design, single sided for the most part, so I made a couple with the DIY technique described below.

Ever since I put a mailbox out on my front gate, I have to check it manually to see if the postman has delivered any mail. That involves getting out of my car on the way in or out, or (ugh) walking all the way out to the post box! So, I’ve now installed a Raspberry Pi by the post box to send a text whenever something is put in the post box!

This is not something that is directly related to the sound system in the car, but more to do with reducing road noise so the music can be heard more clearly whilst driving.
