I am looking for a skilled developer to build a mobile app called "Smart Egg Tester." The app will connect via Bluetooth to a hardware device and display the following information: - Egg freshness level - Egg age (in days) - Safety status (Fresh / Safe to Eat / Not Safe) The app should also include basic data storage functionality to maintain a history of test results. I already have the UI design ready, which will be shared with the selected developer. The project needs to be completed within 4-6 weeks.

...gadget, but a coherent hardware family that makes interacting with my AI models feel tangible, fast, and effortless. At the center is the Desk Hub, a compact, high‑end box that lives on a desk like a small instrument. It has a small front display, a few physical buttons, a subtle light ring or LED bar, a microphone, and a speaker. Internally it runs on an ESP32‑class microcontroller with Wi‑Fi and Bluetooth. The Hub is always powered via USB‑C and always connected to my cloud backend, where all speech‑to‑text, language model processing, tools, and text‑to‑speech live. From the user’s perspective, they can press a button or say the wake word (for example “Hey Assistant”), speak naturally, and hear/see the assistant’s response. The screen shows short status ...

I need a lightweight GPS-based speedometer that runs flawlessly on both Android Auto and Apple CarPlay. The core function is straightforward: show current speed and rolling average in real time, relying solely on the phone’s GPS—no OBD, Wi-Fi, or Bluetooth hooks. Interface The display should be simple and clean so drivers can glance at it without distraction. I do want the freedom to pick custom colors for the main elements to match different dashboards and night/day moods. Extra functionality Alongside the live speed read-out, I want three small extras that stay in the same streamlined spirit: • Trip history that stores date, distance, and average speed for later review. • Optional speed alerts (audible or visual) when a set limit is exceeded. &bul...

I need two quick improvements to my existing mobile app that prints via a Bluetooth thermal printer. 1. Receipt font revamp Right now the printer uses its default typeface, which looks dated. I only want the fonts changed—no logo, no new layout tweaks—just a cleaner, more readable face applied consistently across the receipt. If you need sample ESC/POS commands or the current print template, I can share them as soon as we start. 2. New API endpoint on the app side Alongside the print tweak, the app must call a brand-new REST endpoint that I will expose. The endpoint will return JSON; the app should hit it, parse the response, and act on the result (details once we chat). All networking is done with Retrofit right now, so please stick to that library for consistency...

There are simil...

I’m building a small-footprint PCB around the ESP32 that will serve as the core of several IoT devices. The board must expose reliable Wi-Fi, Bluetooth, and flexible sensor headers so it can drop straight into prototypes and low-volume production runs. Here is the scope I have in mind: • Schematic capture for the ESP32 module with stable power-management, antenna clearance, and USB-to-UART programming interface. • PCB layout (2-layer is fine if performance allows) that remains within 50 × 50 mm, ready for standard SMT assembly. • Breakouts or onboard footprints for common environmental sensors; I haven’t finalised the exact parts, so leave room on I²C and a couple of ADC/GPIO lines for temperature, humidity or motion modules. • Pro...

...behave purely as a Bluetooth speaker. When a stereo .wav file is uploaded to the master, I need the right channel to play locally through its own audio jack while the left channel streams in real time over Bluetooth to the second Pi. If no Left speaker, then the wav file will play both right and left on the master PI. File transfer to the master should run over Wi-Fi or Bluetooth—whichever proves reliably fast enough—and I’d like the code to allow both paths so I can choose at runtime. On the master Pi I will wire two physical GPIO buttons: one toggles play/pause, the other triggers the file-upload routine. Please deliver well-commented Python (or another lightweight language you prefer on Pi) that: • Receives .wav files wirelessly (support...

I need a turnkey Bluetooth Low Energy control system that lets my staff manage indoor electric drift bikes from an Android tablet. When a rider is ready, the attendant should be able to start or stop a bike over BLE with a single tap; if the link is lost or the preset ride time expires, the bike must shut itself down automatically via an onboard, hard-wired fail-safe timer that works even when the tablet or radio link is unavailable. A physical emergency-stop button on each bike must always override everything. Security is critical: only authorised tablets may connect, commands must be encrypted, and the bikes must default to a powerless, safe state on any fault. The system will run completely offline inside a shopping mall, so no cloud services are allowed. I operate between 11 a...
