...for normal operation. I need to run this device from my 12v vehicle battery – either via a cigarette lighter plug or direct battery connection. The device runs fine at 12v, but runs better at a higher voltage. The device’s supplied 240v power supply outputs 30v @ 2.0A/60W. The problem is that when the vehicle engine is started, the current drops and the device reboots. I need a circuit and PCB design that will: a) Be robust enough to live in a vehicle b) Switched (off board) – via screw terminals c) Fused (either on PCB or automotive blade fuse connected to PCB via screw terminals) d) Reverse polarity protection e) Reverse connection protection (i.e. power input connected to output) f) Turn a 12–14.4v DC battery input into a s...

I have a freshly installed 80 kW/h battery-energy-storage system running through a Solinteg inverter on a three-phase supply. The hardware is in place, wired to the grid and the utility meter, the inverter and battery controller show up on Wi-Fi, yet the whole setup sits in an Idle state and refuses to charge or export. I need someone who has already commissioned this brand of inverter or a comparable hybrid setup to walk me through the parameters, safety flags and grid-code settings that typically block first-time operation. FaceTime is my preferred medium, though if necessary I can jump to WhatsApp or Teams/Zoom. I expect the troubleshooting conversation to last no more than about four hours, possibly split into shorter sessions while I change settings or cycle breakers ...

I’m putting together a tightly knit editorial team to roll out an independent, consumer-focused Electric Vehicle portal for the UAE and wider GCC. The long-term vision is simple: become the region’s most trusted reference for everything EV. Our core editorial driver is in-depth, unbiased reviews of electric cars that speak directly to local motorists—range testing in Gulf temperatures, charging-network realities, registration costs, the whole lot. Every review has to be authoritative yet accessible, written with SEO best practice in mind, and backed by solid on-the-ground research. Beyond the written word, I also want each major review to spawn a short social-ready video and an at-a-glance infographic, so skills in concise scripting, basic shooting/editing (thin...

I’m rolling out a new generation of eco-friendly EV charging stations and need a full-featured management platform built from scratch. Here’s what the first release must do for me: • Energy usage monitoring for every session and charger • Remote control—start, stop, reboot and schedule charging • Secure user authentication Role-based access is essential. Administrators configure the network and view global analytics, end-users simply authenticate and charge, while maintenance staff receive real-time diagnostics and alerts. The platform must also talk seamlessly to our existing energy-management system through open, well-documented APIs so we can optimise load and incorporate on-site renewables. REST/JSON is preferred, but I’m open to ...

...ground station that plugs into (or comes pre-paired with) a common VR headset—preferably something open like an Oculus/Meta or DJI Goggles, but I’m flexible if another model makes integration cleaner. Control will be through a traditional RC transmitter; please size the receiver and firmware accordingly and map failsafes for loss of signal or low battery. Because I’ll be flying beyond line-of-sight at times, rock-solid telemetry matters. GPS lock, battery health read-outs, and a home-return switch must be baked in. If you already have experience with Betaflight, ArduPilot, or INAV, let me know which you’d recommend for this range and why. Acceptance criteria • Prototype air-tested at 1 km minimum, documented video proof of stable feed &bu...
