Driving a Blinkt! as an IoT device
I managed to buy a Raspberry Pi Zero when they first came out in December 2015. This was not easy since they were very scarce. I also bought a first-generation case from Pimoroni and some 40-pin headers. With the Zero this header is not pre-installed and it’s necessary to solder it onto the Pi yourself.
I have had various project ideas for this Pi Zero, but had not decided on one until recently. Within the last month or two Pimoroni produced a device called the Blinkt! which has eight APA102 RGB LEDs and attaches to the GPIO header. This costs £5, just a little more than the Zero itself.
My plan was to combine the two and turn them into a status indicator for various things going on that needed my attention.
I have written out a moderately long set of notes for this episode and these are available here http://hackerpublicradio.org/eps/hpr2173/full_shownotes.html.
