QR-pay-to-unlock fridge** using the *no-code / low-dev* method Help with putting this chatgpt project together --- Project: QR-Payment Activated Refrigerator Lock Retrofit a small refrigerator so that students can **scan a QR code, pay via Stripe or Square, and automatically unlock the fridge for ~6–10 seconds** to grab a cold water. The system doesn’t need high security — just a fun, autonomous deterrent to prevent theft. --- What We Need We’re looking for someone who can: 1. Configure a **payment link (Stripe or Square)** that triggers a **Zapier or IFTTT webhook** after a successful payment. 2. Set up a **Raspberry Pi Zero W** (or similar microcontroller) to receive that webhook and trigger a **relay** to power a **12 V solenoid or maglock** for a few seconds. 3. Provide **working Python code** (Flask or similar) for the webhook receiver and relay control. 4. Help wire the lock + relay + Pi, and show how to make it boot automatically. 5. Provide a simple **test/demo setup** (LED indicator optional) so I can easily replicate it on site. --- * Stripe or Square Payment Link → Zapier Webhook * Raspberry Pi Zero W (Wi-Fi enabled) * 5 V Relay Module * 12 V Solenoid or Magnetic Lock * 12 V DC Power Supply * (Optional) LED indicator for “Unlocked” status --- Deliverables * Step-by-step setup instructions (from payment link to hardware wiring). * Python script(s) with brief comments. * Schematic or wiring diagram. * Optional: printable “Scan to Pay & Unlock” QR signage template. * Short remote walkthrough / video call to verify it’s running. --- --- Ideal Freelancer * Experienced with **Raspberry Pi**, **relays**, and **webhooks**. * Comfortable using **Zapier/IFTTT** or lightweight API automations. * Communicative and able to document clearly for a non-engineer end-user. * (Bonus) Experience with Stripe/Square webhooks or IoT projects. --- This isn’t mission-critical security — it’s more of a clever, self-serve fridge experiment. * Examples of small IoT or Raspberry Pi projects you’ve done. * Which platform you’d prefer (Stripe vs. Square + Zapier vs. IFTTT). * Estimated time to deliver and total project cost. ---
