Job Title: Electronics Project: Pressure-Sensitive LED Coaster

Source: reddit-r-forhire

Project Overview

I am looking for assistance in building a custom DIY electronics project. The goal is to create a coaster/puck device that triggers a bright light when an item (a liquor bottle) is lifted from it.

Reference Image: View Design Concept

Project Specifications

The device should be approximately 4–5" round and battery-powered. The functionality is straightforward:

  • Bottle present: Device remains off.
  • Bottle lifted: Red LED immediately begins flashing.
  • Bottle replaced: Light turns off.

Technical Requirements

  • Components: CR2032 (or similar) battery, normally-closed lever microswitch, and a flashing LED.
  • Mechanism: A slightly spring-loaded/floating top plate to trigger the switch.
  • Enclosure: Needs to look polished and discreet (not a breadboard project). A 3D-printed black enclosure with a clear/frosted acrylic top is preferred.
  • Exclusions: No Wi-Fi, Bluetooth, Arduino, logging, alarms, or cameras required.

Deliverables

  • Quantity: 4 units.
  • Design: I can provide a rendering showing the exact design I have in mind.

Compensation

  • Budget: Approximately $100 plus reasonable costs for parts and shipping.
  • Open to receiving quotes.

Location

  • I am located in New Orleans.
