Matthew Wagner wanted to develop a wireless IP camera for both his work and to attach to his dog’s collar. So, he’s taken a Raspberry Pi Zero, a Pimoroni ZeroLipo and a RedBear IoT pHAT and soldered them altogether and added a Pi camera. (He does note that if you’ve got the new Pi Zero W that you don’t need the RedBear!) He’s documented the procedure, including the beginnings of the software, over on his blog. More tutorial parts will appear over the next few weeks, so keep an eye on his pages.
