@Webslinger01

An ageing seven-segment and P10 scoreboard that only works from a hard-wired box is exactly the kind of retrofit I enjoy—the hardware is already there, it just needs a modern brain and a wireless leash. I’ve done similar work driving legacy displays and mechanical systems with ESP32-based custom controllers, including a cassette deck retrofit where I designed the PCB in-house to match an existing harness, and an interactive retail display where I shipped 50 fully working units. Here's what I bring to this: → I’ll first inspect every board, power rail, and driver on-site or from detailed photos, then refurbish or replace what’s damaged—leaving you a clean, reliable display. → I’ll design and build a custom ESP32 controller with a battery-backup circuit (Li-ion + charger) so a mains blip never blanks the screen for the required 15 minutes. → Firmware will address both the seven-segment digits and the P10 matrix for centre messages, with a clean protocol for low-latency updates. → I’ll ship a Flutter app for Android and iOS with big touch targets, live score/timer/team-name editing, and clear status feedback for a volunteer operator. → For the wireless link, I’ll use Wi-Fi with a local access point on the controller—it’s the most reliable in a crowded stadium and keeps latency under 300 ms without depending on venue internet.

@pramodkayast

Hi, I’m an Embedded & Electronics R&D Engineer with 4+ years of hands-on experience in embedded systems, ESP32/STM32, IoT, wireless communication, PCB design, and industrial automation. I’ve developed multiple ESP32-based IoT and automation systems, including smart building, smart parking, smart environment monitoring, wireless control systems, and other real-time monitoring and control applications. I also have experience working with LED-based systems, custom controller boards, displays, sensors, communication protocols, and complete hardware-firmware integration. One of my major projects was a high-end LPBF metal 3D printer, where I designed and developed the complete electronics and embedded system, including the controller PCB, ARM Cortex-M7 firmware, motor control, sensors, laser interface, and overall system integration. I’m comfortable working on both the hardware and software side of this project, including existing hardware troubleshooting, controller development, wireless communication, firmware, and mobile application integration. This is well within my experience, and I’m confident I can handle the project from the electronics and firmware side through to a reliable modern control system. I’d be happy to work on this.

@halaa020

The mobile control side of this project is a strong match for my background — real-time score updates, timer controls, team-name editing, authentication, pairing and a simple operator UI. I can build the Flutter/React Native application and structure the communication layer around Wi-Fi/BLE with clear commands for score, timer, reset and P10 text updates. I do want to be transparent that the PCB refurbishment, power circuit and physical LED-driver work require dedicated embedded/hardware expertise. I would only take responsibility for those areas alongside a qualified embedded engineer rather than overpromise on hardware I cannot properly test. For the application side, I’d focus heavily on connection recovery, low-latency commands, large touch controls and reliable four-hour match operation.
