OwOstick is a simple teledildonic system allowing for internet control of a modded vibrator.
My vibrator wand was a cheapo $20 one from eBay. However, it ran on a tiny battery, and it was getting a bit weak for my purposes. Additionally, it somehow ended up in the laundry and got waterlogged. I had to disassemble it to let it dry, and that was when I thought “well why not just put an Arduino in here?
And so this project was born.
Functional Block Diagram
There are 4 discrete moving parts written in 4 different languages, making this probably one of my most complex projects in terms of that metric. However, each component is relatively quite simple, so that metric is very misleading.
Inside the vibrator is a hastily-soldered perfboard holding an Arduino Pro Mini, HC-05, and a MOSFET hooked up to the existing vibrator motor. See this blog post for more information about the teardown and reconstruction. The Arduino firmware was written in C++.
The stock vibrator appears to have run on a 3.7v lithium ion battery, likely powering the motor directly. Now, though, I have a 7.4v lithium battery feeding into it. As such, the motor tends to warm up when input power is maximized.
The Android app has a very simple interface: select device, possibly select server, and control wand intensity. It is written in Kotlin.
The command relay is also quite simple. It is written in Python and merely serves to relay Websocket messages between the Android app and DOM interface.
Yes, that is a pun.
The DOM interface is a simple web frontend written in React (thus DOM), that just has a simple slider for controlling vibrator intensity.
