I have a Tears of the Kingdom-edition Nintendo Switch OLED that I’d like professionally modded with an RP2040 Picofly. The console is still fully assembled, so the job will include the complete teardown, precise flex placement, micro-soldering of the RP2040 points, clean reassembly and a quick power-on test to confirm the payload boots correctly. The Picofly itself isn’t in hand yet—I’m happy to source it or reimburse you if you prefer to bring your own module, whichever makes the workflow smoother on your side. I’m a total beginner with a soldering iron, so I’m counting on your experience to keep the board safe, prevent lifted pads and leave the install looking as close to factory as possible. Deliverables: • My Switch OLED returned fully working...

I'm seeking an experienced digital circuit designer to create an alarm system for a bilge pumping system on a boat. It’s a one off project is for my existing business. When the 24 volt 15 amp bilge pump activates, from a float switch, a light and buzzer must sound. When the pump has deactivated because the float switch has deactivated, bilge empty, the light and buzzer must stay on until a reset button is manually pressed. If the float switch reactivates the light and buzzer must stay on until reset is pressed. The alarm is to warn the boats skipper the boat has a problem which needs solving. Key Requirements: - Design a digital circuit specifically for a marine alarm system. - Ensure stability and reliability in various operating conditions. Wet , violent movement, noisy. ...

I have two BLDC motors running on VESC-based controllers and I need them responding smoothly to a radio-frequency hand-held remote. The goal is true “tank style” drive: forward, reverse, pivot left or right, plus proportional speed and braking on each trigger. Here is what I still need done: • Bind and map the RF receiver to both VESCs so every channel on the remote translates cleanly to speed, braking and direction. • Set safe current limits, regenerative and active braking parameters, and be sure neither motor over-currents under stall conditions. • Calibrate RPM and refine torque curves so the response is even across the whole throttle range. • Synchronise the two controllers over CAN so they act like one power-train without cogging or desync a...

I have a working electronic product already selling in the United States, yet its current board is dated and hard to manufacture. I hold the original schematics but no PCB files, so the first step will be to extract every detail from the physical board, identify each component, and rebuild the entire design in KiCad. Your primary objective is to reproduce all existing functionality while streamlining the layout for better design efficiency and smoother volume production. As you work, please keep U.S. safety, EMC, and environmental requirements in mind so the finished board is ready for certification. If firmware hooks or test pads reveal embedded code, document anything relevant that a firmware engineer would need to know; full‐scale firmware work is not expected, but component-level in...

The primary challenge in MEMS readout design is capturing microscopic, sub-femtofarad variations in sensor capacitance without the signal being overwhelmed by parasitic noise or electrical interference. While a front-end switched-capacitor (SC) network is highly effective for this capacitance to voltage conversion, its resolution is heavily limited by the non idealities of the internal amplifier. Dynamic amplifiers offer an excellent solution for low-power operation, but they suffer from severe gain variations and performance degradation when moving from theoretical models to practical hardware realization. Key Objectives of this Work: 1. SC Circuit Optimization: Design a switched-capacitor network capable of detecting sub-femtofarad changes while minimizing background noise. 2. Amplifier ...

I have a complete conceptual and preliminary layout for a residential photovoltaic installation that now needs to be converted into formal engineering documents.

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...
