I’m running an Onn Android TV box and want the device to look at a USB drive the moment it powers up. Instead of jumping straight into the stock interface, it should display a simple launcher-selection screen: two large, side-by-side icons—one for the factory launcher that ships with the box and one for my own launcher (already supplied as an APK). Tapping either icon should immediately take me into the chosen environment with no extra prompts. What I need from you is a ready-to-flash image that lives on the USB stick, autoloads at boot, shows the two icons exactly as described, and hands off to the selected launcher cleanly. Please bundle my APK, make sure the default launcher remains untouched, and keep everything seamless so I can plug the drive in, power on, and choose. D...
I need a full-stack hardware designer to turn my concept into a manufacturable prototype board built around Rockchip’s RV1126B. The board must carry 2 GB LPDDR4X, a 32 GB eMMC, microSD slot, on-module Wi-Fi/Bluetooth, and a MIPI-DSI connector that will drive a touch display used strictly for user interface and control. Because this is a prototyping/testing build, I am happy to iterate, but the first revision should already be hand-solderable or assembly-ready at common fabs. Key integrations • Two USB 2.0 ports will each host an external Wi-Fi video receiver; please validate bandwidth and power budgets. • An existing STM32F405-based SkyBrain RC subsystem must be brought onto the same PCB (or docked through a high-speed mezzanine) so every one of its functions—...
I’m building a new electronics–driven venture aimed at solving a pressing agricultural challenge in India and I’m looking for a like-minded partner to shape it with me. I’m based in Guwahati, already plugged into a network of Northeast-focused angel investors, and I’ve taken a tech startup from idea to market before, so I understand everything from company registration to early-stage fundraising. My preference is to harness smart electronics—whether that means low-cost sensing, embedded control, IoT devices, or other hardware-software hybrids—to boost yields, cut waste, or otherwise empower small and mid-scale farmers. If you have concepts in precision farming, post-harvest monitoring, or field-level automation, let’s explore them. I’m...
I have a Particle Boron development board and would like to create a compact proof-of-concept monitoring system using two reed switches and a split-core current transformer (CT). The device should continuously monitor the sensors and automatically send an SMS notification to my phone whenever either reed switch changes state or the measured current exceeds or falls below configurable threshold values. The firmware should be developed for Particle Device OS and include cellular SMS functionality. Each alert message should report the current status of both reed switches, the real-time current measurement from the CT sensor, and the exact timestamp when the event occurred. I would also appreciate assistance in determining and configuring appropriate threshold values for both the reed switch ...
I need a compact, battery-powered hour meter that bolts onto a piece of marine equipment, connects to the boat’s Wi-Fi, and silently counts every minute the engine runs. Beyond simple hour logging, it must also sample and report its own battery voltage so I can tell when the internal cell is getting low. The device should push both data points—total run-time and current battery level—to a cloud endpoint I’ll expose. I plan to read everything from a web-based remote dashboard, so no on-device screen is required. An LED or brief buzzer chirp during initial pairing is fine, but the unit will spend most of its life sealed in a damp engine bay. Reliability and low standby draw are therefore critical. Please deliver: • Hardware schematic and bill of materials...

I need a custom-built RFID reader that can reliably pick up standard identification tags in an outdoor setting. The enclosure must withstand sun, rain, and an occasional hose-down while still offering stable read range and low error rates. At this stage I am open about the operating band—LF, HF, or UHF—so long as we can balance range, power consumption, and tag cost. I expect us to discuss the trade-offs early and lock the decision in before PCB layout begins. Here is how I see the work flowing: • Electronic design—from antenna matching through to the microcontroller or SoC that will parse tag IDs and forward them over a simple UART, USB, or Ethernet interface. • Firmware—clean, documented C/C++ code (Arduino, ESP-IDF, or a bare-metal toolchain is fin...
