Firmware Jobs

I need a single physical remote that can operate both my television and my Amazon Fire TV Stick without forcing me to juggle two handsets or dive into menus. The core requirement is seamless switching between the two devices—ideally it should “just work”, letting me power the TV on/off, change channels, and adjust volume, while also retaining full control over the Fire TV interface. Essential details • Form-factor: traditional handheld remote with tactile buttons (no touchscreen or voice mic necessary). • Button set: at minimum power, volume ±, channel ±, and the usual directional/OK cluster so that navigating Fire TV is comfortable. • Connectivity: IR for the TV and whatever protocol you judge most reliable for Fire TV (Bluetooth LE is t...

I need a proven method to remove the carrier lock on a TOZED ZLT T30S router. Please deliver a concise screen-recorded tutorial video with clear voice narration that walks me through every step—from initial preparation and required drivers right through to confirming the device is fully unlocked and accepts any SIM. Alongside the video, include downloadable resources such as the exact software, scripts, flash tools, firmware files, or configs you use in the demonstration so I can replicate the process without hunting for additional materials. Acceptance will be based on: • The video showing a locked router, the complete unlocking workflow, and a final reboot with a different carrier SIM successfully registering on the network. • All referenced files provided and v...

I’m building a wearable and need someone who can own both sides of the stack: the low-level firmware written in Keil and a companion mobile application that runs smoothly on iOS and Android. Firmware embedded code must remain lightweight, responsive, and power-efficient. You will start from a fresh Keil project (ARM Cortex-M0+), implement the drivers sdk , and expose a clean interface for the app to trigger vibration, screen updates, battery level monitoring—whatever the final hardware supports. Mobile apps I expect two native builds released through TestFlight and an Android APK (or Play Console track). The apps should pair with the wearable, stream updates in real time, and relay basic settings such as vibration pattern or do-not-disturb windows. Feel free to choose Swift...

I need a compact cable that lets me sit anywhere in the room—or the building—and still drop straight into a device’s serial console. The brief is simple in concept but demanding in execution: take a traditional console lead, add a Bluetooth link, and make it speak fluently to both RS-232 and TTL ports without me having to swap hardware. Here’s the outcome I’m after: • A working prototype that auto-detects and level-shifts between ±12 V RS-232 and 3.3 / 5 V TTL. • On-board Bluetooth module (Classic, BLE, or dual-mode—your call, as long as latency stays low and pairing is painless). • Schematics, BOM, firmware source, and a concise setup guide so I can reproduce or modify the design later. If you’ve already built wireless ...

I’m running the stable release of DietPi on an Orange Pi 5 Plus (RK3588 with a Mali-G610 GPU). Under X11/ every OpenGL check still reports llvmpipe, so everything is falling back to software rendering. What I need • The system must load and use the proper GPU driver so that `glxinfo | grep renderer` (or an equivalent command) reports either “Mali-G610”, “Panfrost”, or “DRI Rockchip”—anything that confirms the GPU is really doing the work. • Once that is working, RealDash should automatically benefit from the acceleration; the overall aim is smoother, faster general system performance. • A concise set of step-by-step commands or a shell script that reproduces the setup on a fresh DietPi image, along with a brief explana...

I need an experienced printer repair engineer who can step in immediately and keep our fleet running. You will focus on emergency repairs for inkjet, laser, and multi-function devices, heading on-site as soon as a ticket is raised. Your day-to-day work will center on diagnosing hardware or firmware faults, swapping damaged parts, recalibrating sensors, and verifying test prints so the user can get back to work without delay. Whenever a unit is beyond quick repair, I’ll rely on you to advise on replacement options and handle the installation of the new machine as part of a seamless hand-over. Clear, professional communication with end users on-site is important—explaining what went wrong, how it was fixed, and any preventive steps they should take. Please keep concise service...

Fix PiKVM V4 Mini Microphone (WebRTC audio not working) Description: I need help enabling two-way audio on a PiKVM V4 Mini setup. Everything works except the microphone from my personal laptop (MacBook) does not transmit to my other computer through PiKVM. Video and HDMI sound (incoming audio) already work. I only need the USB microphone emulation (outgoing audio) to function. What’s already done: PiKVM V4 Mini connected to work PC (HDMI IN + USB). Audio through HDMI works fine. PiKVM updated to the latest firmware. WebRTC mode active. /etc/kvmd/ file includes: otg: enabled: true devices: mic: type: usb class: audio enable: true Restart and module commands run (systemctl restart kvmd, modprobe g_audio). Still no microphone toggle or “PiKVM M...

I’m building a compact, medically-oriented wearable that measures bio-impedance through four skin electrodes, monitors temperature, optionally logs motion with an IMU, and streams everything to an iPhone via BLE for HealthKit integration. The board must also listen for, and correctly parse, broadcasts from both Abbott and Dexcom continuous-glucose patches so the data can be combined in the same mobile app. Core requirements • MCU: Cortex-M4 class; I’m open to either the nRF52840 or the STM32U5—choose whichever lets you meet the radio, power, and memory demands most elegantly. • AFE: MAX30009 wired to four electrode pads for single-ended or differential bio-impedance measurements. • Sensors: digital temperature sensor (your choice of proven part); opt...
