SMACK!
SMACK! is a one-button automation activator, that triggers digital and physical actions. It can send USB shortcuts, call webhooks, and trigger smart home automations. Simply SMACK to activate chaos (or productivity)!

Added Outputs
So, I have now added some outputs! I did a bit of research, and ideation, and decided that to make this more chaotic, I'd add both a vibration motor and buzzer, allowing for it to make some noise and rumble when you hit it. I also added some LEDs.

Swapped LDO
Quick update, but basically I just found out the LDO I was using could only output ~150mA, so I swapped it out for the more powerful AP2112K, which can output ~600-800mA.

Added the ESP32
So after finishing all my research, I started off by adding the main MCU circuitry. This includes an ESP32-S3-WROOM-1 (i'm using a WROOM to make soldering it easier), the USB-C port, and an LDO to provide a stable 3.3v line.

Planning
So for now I just started with a bunch of planning. I've decided on the core features, and the overall hardware/microcontrollers.
Basically, SMACK! is going to be a button that activates a 'scene' when you hit it, via calling webhooks, USB commands, etc. So when you sit down to work, you can 'smack' the button, and it will set everything up, open apps, call smart home commands, etc.
(I don't really have a great image, so here's an image of a button that gave me inspiration to make an extra large button that does something)
