I misunderstood your first post, I thought you wanted to replicate the setup on a raspbpi.
In that case, you should get the attiny84 from anywhere reputable.
I got it from here: https://www.amazon.co.uk/gp/product/B00P4E2XUC
You are also going to need a battery holder: http://eud.dx.com/product/diy-4-5v-3-slot-3-x-aa-battery-hol...
And I'm using this arduino for the master RX hub: http://eud.dx.com/product/new-nano-v3-0-module-atmega328p-au...
And if you want to make your life easier, a little extractor tool: http://eud.dx.com/product/proskit-908-609-ic-chip-extractor-...
To program the attiny84, see @gh02t's post[1].
I opted for the use-another-Arduino-as-the-programmer method[2] -- I don't know if you can do it with the nano, I did it with an old Arduino Duemilanove I had laying around.
And here's a fritzing sketch[3] (ignore the fact that there are 4 batteries, the library didn't have a model for the 3 battery case holder).
If you need help with anything after they arrive, feel free to email me (email is on profile website).
