Elektronik Tasarımı Jobs

I'm looking for a small, electronic metronome with the following specifications: - **Form Factor**: Circular (like a 5cm button) or flat (like a credit card). - **Controls**: - Two functions: Adjust volume and cadence using sliders or rotating knobs. - Controls should be quickly accessible without sighting. - On/off activation via single tap. - **Power**: USB-C recharge. - **Portability**: Must fit in a pocket or attach to a sleeve. - **Memory**: Remembers last settings. Ideal skills and experience: - Experience with electronic device design - Proficiency in creating compact, user-friendly interfaces - Knowledge of rechargeable battery integration and memory functions Looking forward to your proposals!

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 and 20 b...

Project Description: I'm building a compact, consumer-grade handheld device that hosts multiple ARM processors and modules on a single 4-layer board. The design must accommodate a high-speed USB hub, balanced power distribution, and impeccable signal integrity without exceeding the layer budget.

Multi-Arduino Industrial Control System Development (Isolated Communication + Analog + Digital I/O) Project Overview We are developing a modular measurement instrument based on multiple interconnected Arduino boards. Each Arduino handles a dedicated subsystem (UI, motor control, pH control, temperature control) coordinated by a Master Arduino. We require an experienced embedded systems freelancer to: • Design robust firmware architecture • Implement reliable inter-Arduino communication • Ensure electrical isolation to prevent analog noise/crosstalk • Optimize motor control, sensor acquisition, and closed-loop control • Deliver clean, documented, production-ready code • All components should be easily sourced in India This is not a beginner Arduino project &md...

PCB Technical Blog Writing Guidelines Each week I publish in-depth, EEAT-driven articles that demystify printed-circuit-board design and manufacturing for an audience of intermediate professionals. The primary goal is to educate—every post must read like it was penned by someone who has actually laid out boards, debugged traces, and wrestled with impedance calculations, not by a generic content mill. Scope of work You will draft original how-to guides that walk readers through real engineering challenges (e.g., stack-up selection, thermal relief strategies, DDR routing tips). Practical detail and accurate terminology are essential; surface-level summaries or re-hashed competitor pieces won’t be accepted. Quality standards • EEAT: demonstrate personal experience,...
