We are looking for an experienced electronics / embedded hardware freelancer to help assemble and test 5 pilot units of an ESP32-S3 based IoT mini controller. The PCB/PCBA boards are already designed and manufactured by JLCPCB. The firmware file is also ready. This project is not for PCB design and not for firmware development from scratch. The main task is physical assembly, firmware flashing via USB-TTL, and basic bench testing. The final goal is to prepare 5 working pilot units in the correct order: Milestone 1: Assemble, flash and test 1 pilot unit first. Milestone 2: After the first unit is validated successfully, assemble, flash and test the remaining 4 units using the same process. Scope of work: * Mount the PCB/PCBA into an IP65/IP66 enclosure * Connect the external Wi-Fi an...

I need a precise, low-resistance solder joint made on the battery leads of my drone. The task is straightforward: take the existing electrical wire coming from the battery pack and solder it securely to the designated battery connection pads/connector on the airframe. A clean, shiny joint with proper strain relief is crucial so the connection can handle both current spikes and the vibrations that come with flight. Bring whatever tools you feel most confident with—a temperature-controlled iron, fine rosin flux, decent solder (60/40 or lead-free is fine if you’re comfortable), and heat-shrink tubing for insulation. Once the joint is complete, I’ll do a quick continuity and voltage drop test; as long as it passes and looks solid, the job is done. If this is something you c...

Custom PS Navigation Controller Project Specification Goal: Create a modernized PlayStation Move Navigation Controller (PS Nav) that preserves the original ergonomics, thumbstick location, and feel while addressing the hardware limitations of the original design. The project is not intended to redesign the controller. The objective is to preserve the PS Nav experience as closely as possible while modernizing its functionality and reliability. Core Design Philosophy: The controller must retain the original PS Nav shape, grip angle, and thumbstick placement. The thumbstick location is the most important feature and must remain unchanged. The stick should remain in the same top-mounted position as the original PS Nav rather than adopting Xbox, PlayStation, Joy-Con, or Azeron-style layout...

I have a pair of ex-Japan headlights and matching tail lights for a single car model. The units already use LED technology, but age, shipping and moisture have left them with flickering segments, cracked seals and the odd dead diode. My goal is to get them back to flawless, road-legal condition instead of buying new assemblies. Here’s what the job involves: • Bench-test every function—low beam, high beam, DRL, indicators, brake, reverse—to pinpoint faults. • Replace or re-solder any failed LEDs, drivers, resistors and corroded wiring. • Reseal and polish the lenses so they stay clear and condensation-free. • Verify beam alignment and light output match factory specs for this model. • Supply a brief video and photos that show the complet...

I have a run of industrial-grade PCBs that must be populated with both SMD and through-hole DIP parts—well over 500 individual components in total. Reliability is critical because the boards will sit at the heart of industrial equipment, so every joint needs to be crisp, void-free, and compliant with standard workmanship guidelines (IPC-A-610 or equivalent). Here is what I need from you: • Pick-and-place or precise hand placement of all SMD parts followed by reflow or hot-air soldering as appropriate • Clean, consistent hand-soldering of the DIP components, trimming leads flush afterward • Visual inspection under magnification and basic electrical continuity checks to confirm there are no bridges or cold joints • Return of the fully assembled boards, safely...
