This is a really interesting project, I’ve worked quite a bit with Raspberry Pi, Arduino and ESP32 for control systems and automation, including UI and hardware interaction. Controlling charging time, handling timers, and interfacing with peripherals like relays or controllers is very straightforward on the Pi. I usually build these systems with reliability in mind so they can run unattended without issues (most of my projects are for industrial scenarios). I’m open to keeping things lean and practical while still delivering something solid. I can help you get this up and running! Thanks

Hi, I'm not sure about mobile payment you mension about card reader. Do I have to do also mobile App? Or if you already have existing App, how to manage the payment gateway after scan qr code?

Hi, I can help you build this Raspberry Pi kiosk and have extensive experience in both embedded hardware control and UI design. I will develop a sleek interface using Python and Kivy that supports multiple user accounts for administrative tasks and ad management. I am familiar with Square API integration for card and phone payments and can implement a precise timer-based relay system via GPIO to control the scooter chargers. My background as an electronics engineer ensures the transaction logic and hardware switching will be both reliable and professional. I understand the importance of balancing quality with affordability for your business and would love to discuss a cost-effective roadmap for this project. Best regards

Designing a user interface for a kiosk that manages charging sessions and ad uploads requires a clear understanding of user flow and embedded system interaction, and that’s where I can help. I’ve previously developed similar UI/UX for point-of-sale systems integrating payment processing and user authentication, ensuring a smooth and intuitive experience. I'll focus on building a secure and efficient system with the Raspberry Pi, incorporating the Square card reader integration and the timed charging functionality you described. I estimate I can deliver a functional prototype with basic user account management and ad upload capabilities within 5-7 days, allowing for iterative refinement based on your feedback.

Hi, there This is a great concept—and the key to making it successful is a reliable control system + simple, smooth user experience. I can help you build a complete solution on Raspberry Pi that is stable, easy to use, and ready for real customers. I have experience with embedded systems, Raspberry Pi, payment integration, and control logic, so I can handle both the backend and the user-facing side. What I will deliver: - Raspberry Pi software to control the charging system (relay/driver control) - Integration with Square reader for tap/card/phone payments - Clean, simple UI/UX for selecting charging time - Timer-based control (start after payment, auto-stop when time ends) - Basic multi-user admin system (2–3 accounts) for managing settings and ads - Ability to upload/display ads on the kiosk I will keep the system lightweight, reliable, and easy to maintain, which is important for a solo business. I understand your budget situation, so I’ll work with you at a fair and affordable rate while still delivering quality work. Estimated Budget: $100 – $200 (can be split into milestones) Timeline: 7 – 14 days I’m ready to discuss details and help you bring this to a working product.

Hi, I'm an Automation & Embedded Systems Engineer with hands-on experience in Raspberry Pi, embedded Linux, Python, and UI development. This project fits exactly within my skillset. Here's how I'd approach it: HARDWARE & PAYMENT I'll integrate the Square card reader via Square's official SDK — handling tap, card, and phone payments cleanly with proper transaction logging. CHARGING CONTROL I'll use the RPi GPIO to control the charger relay — user selects time on the interface, payment goes through, charger activates, timer runs, charger cuts off automatically. Clean and reliable. USER INTERFACE Smooth, sleek touchscreen UI built with Python (Tkinter or PyQt5) or a lightweight web-based interface. Multi-account support with 2-3 operator logins for kiosk management and ad uploads. AD MANAGEMENT Simple admin panel where each account can upload and schedule ads displayed on the kiosk screen when idle. WHAT YOU GET Full source code documented and clean Easy to maintain and expand Ready for future locations/scaling Support after delivery I work clean, communicate clearly, and deliver what I promise. Budget looks fair for the scope — let's talk details. Adem

Charging kiosk is a fun one to wire up. The tricky part isn't the Pi or the Arduino separately, it's making sure the serial communication between them is reliable enough that a charge controller state change (slot occupied, charge complete, fault) always reflects correctly in the UI, even if the user is mid-payment. My approach: Pi runs the touchscreen UI in Python with Kivy, polling the Arduino over serial for slot states. Arduino handles the charge controller logic and reports back clean status codes. Payment flows through a card terminal SDK or QR-to-pay depending on what you're using, triggering slot unlock on confirmed payment. Each layer stays simple and testable on its own. Deliverables in 5 days: - Arduino firmware for charge controller comms + slot state reporting - Pi UI with slot selection, payment flow, and status display - Serial protocol between the two, documented - Basic fault handling (slot stuck, payment timeout, controller error) $220 fixed. A few things would help me scope this tightly: 1. What charge port types are you supporting, and what's the current spec per slot? 2. Payment method, card terminal, QR code, NFC, or something app-based? 3. Do you have an existing schematic or wiring plan, or is this starting from scratch?

Expert in EMV Payments, MDB Protocol & Kiosk Automation I am a highly experienced developer specializing in kiosk automation and payment systems. My background is uniquely suited for your Charging Kiosk project, having previously worked at Cantaloupe, where I gained extensive experience with EMV card readers, card data extraction, and payment gateway integration. I have deep technical knowledge of the MDB (Multi-Drop Bus) protocol, which is critical for reliable communication between the kiosk controller and payment peripherals. Technical Skills I bring to this project: Languages: Expert-level proficiency in C, Rust, Go, and Python, allowing for high-performance and secure firmware/software. Hardware: Extensive experience with Arduino and Raspberry Pi for hardware-level control. Automation: I have developed multi-threaded applications using Nushell to handle complex, concurrent tasks like simultaneous charging session management and payment processing. Payment Security: Proven track record in integrating secure payment workflows and handling sensitive transaction data. I can ensure your kiosk is not only functional but also secure and compliant with payment industry standards. I am available to discuss the specific hardware components (relays, sensors, and readers) you plan to use. Looking forward to bringing my industry experience to your project.

@InnovativeCre1

Hello! Your project is a great match for my background. I've built a Raspberry Pi system for public transport where monitors on the back of vehicles displayed ads managed through a Flask web dashboard with multi-user access — the same Pi + web UI + user account stack you need here. I also built embedded hardware communication for an EV company, so interfacing software with a physical charger controller is familiar ground. I can build you a smooth, sleek kiosk UI with Square tap payment integration, a timed charging session system that automatically stops the charger on expiry, and 2–3 user accounts for kiosk management and ad uploads. I'd love to be your go-to developer for the future work you mentioned too.
