    I am looking for an engineer or a small engineering team to help build a working prototype of a wearable smart ring that communicates with a thin wallet card device placed in a wallet. The purpose of the device is to prevent wallet loss by alerting the user when the wallet moves more than a short distance away from the ring. The system should provide two types of alerts: a vibration alert in the ring and an optional audio alert. The project goal is to create a fully working prototype that demonstrates the concept in real life. Experience with miniature electronics, wearable devices, Bluetooth communication, and prototype development is preferred.

    I’m building a small arcade-style attraction made up of six identical stations. Each station will recognise when its hand-held controller is lifted by means of a magnetic sensor—or any other proper kind of sensor —then launch a three-minute countdown. Here is the user flow I need you to realise: 1. Controller is lifted → internal timer starts. 2. An OLED screen at that station immediately shows the remaining time, counting down in real time. 3. When the three minutes expire the screen simply replaces the countdown with a clear “Game Over, move to next zone ” message + a buzzer or light; 4. Once the controller is set back the system must reset itself, ready for the next player. Hardware thoughts so far: magnetic (reed or Hall) sensor to detect li...

    I run Odoo 19 on the free (community) build and would like it to talk seamlessly with the Intui platform. The goal is hands-off order management: as soon as an order appears in Intui it should land in Odoo, and if that order is changed or cancelled later, the same change must show up in Odoo in real time. Beyond the order itself I also need the integration to pull across the related customer record and keep product inventory levels accurate in both systems. Whenever a sync problem occurs I want an automatic email alert so I can react immediately; silent logging alone isn’t enough. I expect you to deliver an installable Odoo 19 module (Python, XML, possibly JavaScript for UI tweaks) plus clear setup instructions and a brief test plan that proves: • new Intui orders create corr...

    My Squarespace store already takes orders, TRUX’s dispatch API is live, and QuickBooks Online is running—we just need them to talk to each other. I want every new Squarespace order to pass through the TRUX API and then land in QuickBooks automatically, carrying across the full order record plus the customer’s details. Here’s what the finished workflow should do: • Capture each completed checkout on Squarespace, convert it to the format TRUX expects, and push it in real time to their API. • From TRUX, forward the data to QuickBooks so a matching sales transaction is created and the customer profile is added or updated. • Keep customer names, addresses, emails, and phone numbers in sync between the three systems without duplicates. • Ru...

    I’m looking for a small utility that focuses on one job only—submitting WhatsApp message templates for approval. All I need is a simple UI where I can choose a .txt file from my desktop, hit “Submit,” and have the utility forward that file to the WhatsApp template-approval endpoint under my Business account. Manual upload is the only workflow I require; no API batching or automated cron jobs at this stage. For now, the tool must accept plain-text (.txt) files exclusively. If you can leave the door open in the codebase for future PDF or DOCX handling, that’s a bonus, but it isn’t part of this initial brief. Deliverables • Stand-alone desktop (or lightweight web) app that lets me browse, select, and submit a .txt template file to WhatsApp for appr...

    I want a lightweight program that links the 20 Schneider EM6436 energy meters installed on-site to my PC and streams their readings in real time. The meters already sit on the local network; what I need is the software layer—code plus installer—so I can open the application and immediately see up-to-date values without having to poll each unit manually. Language is flexible. If you prefer Python, C++, Java or another mainstream option, propose what offers the most stable performance for continuous acquisition. I’ll run the finished program on Windows, so please include any libraries or runtime packages I must install. Display format can be simple; the priority is receiving clean real-time data that I can later export or feed into other tools. If you have a quick way to ...

    I have 10 Databricks pipeline YAML files and 9 associated Python notebooks that all need the same set of edits. Every change is straightforward yet must be applied with absolute consistency. YAML adjustments required • Insert a new task at the very top of each tasks section. I will supply the exact naming convention so you can drop it in without guesswork. • Add a dependency from the existing main task to this newly inserted task. • Modify the log-handling task so its failure condition points to the new logic, and change the hard-coded error description to a dynamic value. Notebook adjustments required • Before any exception is raised, add one line that captures the error message and stores it for downstream logging. Reference files that show the pattern for each...

    I run a custom CRM called Ilumino and need an impartial, one-off consultation (about 1–3 hours) to decide which cloud VoIP platform to pair with it. I’m already looking closely at JustCall and Aircall, and my top priority is the strength and flexibility of their API capabilities. The chosen solution must comfortably handle: • Call recording • SMS integration • Analytics and reporting What I expect from our session: you’ll walk me through each platform’s API/webhook structure, outline the real-world pros and cons for a custom CRM like mine, flag any hidden costs or licensing quirks, and help me draft the right technical questions for my Ilumino developers. If you’ve previously connected VoIP tools to bespoke CRMs, especially where detailed...
