Accessories

• Power pack - $27 - [1]. Yale sez - Benefits:

- Rechargable - Replaceable (especially for a camera). - USB so you dont need to get a battery pack going. - In the past I've used this as power exclusively for a Pi on my desk. I mostly do Headless-Raspian when I'm playing around. I must get 6+ hours from 1 battery. Maybe more.

• Sound - Yale sez - 1. All mics seem to suck so far. I've used these ones:https://www.adafruit.com/product/3367?gclid=EAIaIQobChMIm6K45dv05gIVCaGzCh2UXwjYEAQYAiABEgIc__D_BwE

- No pickup- Terrible sound 2. I've also done it this wayhttps://www.adafruit.com/product/1475 - This is decent adapter and lets you get different mics. I've had some Lapelle ones that I used for Elly's talking AI: https://fellowsblog.ted.com/singularity-is-near-and-its-in-the-form-of-a-dachshund-named-elly-79431b1d3681
