I have a compact aluminium case measuring 5 cm × 5 cm × 5 cm that needs to be turned into a simple passive module. Your task is to drill four clean, evenly-spaced holes, fit four standard 3.5 mm audio jacks, then hard-wire the jacks internally with three resistors and a few short runs of standard copper wire according to the small schematic I will supply. The enclosure arrives to you blank; I expect precise machining so the jacks sit flush without burrs, followed by neat, reliable solder joints. Once everything is wired, close the box, test for continuity, and label the I/O if you think it helps. Deliverables • Finished, fully-wired enclosure returned in good condition • Clear close-up photos showing hole quality, solder joints, and final continuity test results If you own a drill press or similar rig for straight, centered holes and are comfortable with basic electronics hand-soldering, this should be quick work. I’ll reimburse tracked shipping both ways so we can focus purely on the build quality. Let me know your lead time and we can get started. All the components are from china, so I would prefer to award someone from China to avoid useless exports and imports.

Hello, ✅ What jack spacing/tolerance is required to avoid enclosure stress and ensure flush mounting? ✅ Should wiring follow a specific resistor network (impedance/load target) from your schematic? I will machine precise holes, install jacks cleanly, and complete neat, reliable soldering with continuity testing and labeling. I have hands-on experience in small enclosure fabrication and electronics assembly. Let’s connect to review the schematic and proceed. Best regards, Mohand

Hi, I can assemble this compact audio jack enclosure with careful drilling, clean fitting, and reliable hand soldering. I understand the important part is build quality: four straight and evenly spaced holes, flush mounted 3.5 mm jacks, no burrs, neat internal wiring, correct resistor placement, and proper continuity testing before the enclosure is closed. I can follow your schematic exactly, take clear close up photos of the hole finish, solder joints, internal wiring, and final test results, then return the completed unit safely packed. Since the parts are coming from China, you can ship the components directly from the supplier to reduce unnecessary handling and delays. Please share the schematic, jack dimensions, and preferred hole positions so I can confirm the build details before starting. Best regards Ankit

Hope you are doing well, the project is simple and clear with focus on precision drilling and clean wiring work. Recently I performed small mechanical assembly and drilling tasks with accurate hole alignment and clean edge finish. I also completed basic electronics soldering with reliable joints and continuity testing for small modules. I can complete this enclosure assembly with precise machining and neat internal wiring. Can you confirm exact hole diameter and spacing for the audio jacks before drilling? Sincerely, Luba

Hi there, I read your requirements carefully, and I can assemble the mini audio jack enclosure with clean machining, neat soldering, and proper continuity testing. I can drill four evenly spaced holes in the 5 cm aluminium case, fit the 3.5 mm audio jacks flush, and wire the internal connections with the three resistors and copper wire according to your schematic. I’ll keep the solder joints clean, check continuity after assembly, and provide close-up photos showing the drilled holes, wiring, solder points, and test results. Since you prefer someone in China to avoid unnecessary shipping/import issues, I can coordinate around your component location and keep the build process simple and practical. Cost: $120 || Timeline: 1–2 days after receiving parts and enclosure Payment and timeline details can be discussed further to align with your expectations. I’d be happy to complete this carefully and return a clean, tested passive module. Best regards,

Hi, Even though the task is simple, the main risks are misaligned holes and poor soldering inside a tight enclosure. I’ll make sure both are handled cleanly. My approach: • Accurate hole layout and drilling using proper fixtures • Clean finishing to avoid scratches or burrs on the aluminium case • Short, tidy internal wiring to prevent stress or shorts • Solid solder joints with proper strain handling • Full continuity verification before sealing I can complete and ship quickly, with photo documentation at each stage.
