README
README.mdbacon - Balloon Ascent Controller
The goal of this project is to control the rate of ascent of two high-altitude balloons, to keep at the same relative altitude as they ascend.
A simulator is included in simulator/. Run tongs.py to start, then open client.html in a browser. Power up the two payloads to begin auto-discovery. Once that is finished, the simulated flight begins and shows a live plot of progress.

Questions
How big is the Payload pcb PCB?
It measures 83.8 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Payload pcb use?
43 parts, built around the ATMEGA328-PU and MC33063AD. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Payload pcb KiCad files?
From the nleve/bacon repository on GitHub, at the commit this page was made from: the board is pcb/payload_pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Payload pcb design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
