VIBROSCYPEK

Ever wanted to use a traditional Polish cheese for wireless communication?

Here's an answer to your quandary - the VIBROSCYPEK.

A shitpost manifested into physical reality.

What is this?

The VIBROSCYPEK is a pair of wireless communicators built into 3D-printed shells shaped like oscypek, a traditional Polish smoked sheep cheese. Assembled from pieces of e-cigs and crap from a drawer, this project is a glorious testament to junk-drawer engineering.

And yes, they actually talk to each other.

Features

• Wireless Communication: Two oscypki can communicate with each other.
• Simple Pairing Mechanism: When two devices are brought very close together, they use the signal strength (RSSI) to determine the pairing partner.
• Custom Enclosure: A lovingly crafted, 3D-printed oscypek shell. Because why not?
• (Vibro) Haptic Feedback: The name implies it, right?

The Tech

This project was a great excuse to learn a new protocol.

• Hardware: ESP32-C3 Board
• Communication: ESP-NOW
  • A nifty connectionless Wi-Fi communication protocol from Espressif that acts as a simple abstraction layer over standard Wi-Fi/Bluetooth, making peer-to-peer communication incredibly easy.

The Build

Assembled with love, solder, and whatever was available.

• 2x ESP32 development boards
• 2x Vibration motors
• 2x Momentary switches
• 2x Slide switches (for a hard power disconnect)
• 2x Tiny BMS PCBs
• 2x Rechargeable Li-Ion batteries (did you know the 'disposable' e-cigs that people throw out come with a perfectly re-usable battery?!)
• The disembodied guts of various e-cigarettes and other drawer treasures
• 3D printed enclosure (.stl and .3mf files attached)
• 16x small magnets (5x2.5mm) - .step file attached, so you can adjust to what you have on hand

In hindsight, I probably could have made the enclosure just two pieces without the seperate slightly flimsy usb-c cover, oh well
