What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Roomba exposes both unregulated battery voltage (+14v, GND), and a 5v TTL serial interface via it's mini-din connector. Also exposed is an active-low signal pin called DD (Device Detect) that can be used to wakeup a sleeping/off Roomba.

Rpi has a 3.3v TTL serial interface exposed on it's header pins. Also, Rpi exposes +5v, +3.3v, GND, as well as GPIO pins.

We can leverage the Roomba battery to power the Rpi by adding a voltage regulator circuit between the roomba min-din battery pins and the 5v/GND power pins on the Rpi header. I've chosen the following part from the RC community (called a UBEC Universal Battery Elimination Circuit) to power the Rpi: this or this

To convert the 5v Roomba signals (both serial and DD) to/from 3.3v, I've chosen this:
