## Hardware Hacking

- Figure out how to connect a Raspberry Pi to a DHT22 and receive signal output
- Develop a system to display components on an e-ink Dashboard ([Building a Julia-Powered E-Ink Dashboard: A Dev Log - #3 by TheCedarPrince](https://discourse.julialang.org/t/building-a-julia-powered-e-ink-dashboard-a-dev-log/130709/3))
- Document and add testing harness for WiringPi.jl
- Build CI configuration for Raspberry Pi + Julia

Oh I should mention that I brought all the hardware for this with me!

If you want to hack on this, just reach out! And if you want to borrow the machinery while we are here, happy to lend it to you as well – just get it back to me in time for the Hackathon! 😃
