    I’m building a compact electrolysis hair-removal unit and need a full schematic and PCB layout that an assembler can take straight to production. Core requirements • Control core: ESP32 must set DC voltage (0–24 V), DC current (0–5 mA) and RF power (up to 2 W at 13.56 MHz). Hard cap current limit for DC, the power supply must be unable to supply more for safety. • Dual-path power: DC and RF run independently yet may operate simultaneously. The RF path travels down the probe needle, which is the DC low-side return. A bias-tee approach seems most practical; I’m open to alternative RF/DC combining networks if you can justify them. • High-side connection: the positive DC terminal links to a metal plate the user sits on. If a negative-rail design is e...

    I’m refining a compact control-circuit project that must live on a single-layer PCB.

    A dedicated PCB will drive a self-service car-wash “vendo” unit built around an Arduino Nano. The board must accept the pulse output from a standard electronic coin slot, translate each valid coin into the required runtime, and use that signal to energise five independent relays that handle pumps, valves, or lights. All relays share a common 12 V source, yet the Nano and logic lines stay safely at 5 V, so on-board regulation (12 V → 5 V buck or linear, as you judge appropriate) is part of the layout. The relays themselves need fly-back protection, status LEDs, screw-terminal or JST headers for easy field wiring, and clear silkscreen labelling. A USB-B or tag-connect footprint for in-circuit programming is also required. Deliverables • Complete schematic (KiCad...

    I’m building a handheld device that lets me roll a ball across any flat surface and have it actively steer itself so the pen mounted inside draws in the exact direction I choose. An optical-flow sensor will read surface motion, my code will translate that into heading commands, and two small motors inside the ball will supply the corrective spin. The overall sketch is already under way, but I need a specialist who knows Arduino-style hardware and, more importantly, how to marry miniature motors with an ESP32-C module for precise directional control of the ball. Your main focus will be advising on the right motor format, driver circuitry, power budgeting, and the physical/electrical integration so the firmware can call simple functions like setHeading() or setVelocity(). I’m ...

    I’m bringing a brand-new electronic charger to market and need an engineer who can turn my concept into a fully working prototype. The focus of this engagement is the complete design and prototyping phase—circuit architecture, component selection, enclosure layout, PCB, and initial functional build. Compact size is the single most important design driver, so every decision—from transformer topology to enclosure wall thickness—has to work toward a slimmer footprint without compromising safety or performance. I’m open to creative approaches such as GaN or other high-efficiency solutions if they help us meet that goal. To move forward, please send a detailed project proposal that outlines: • Your approach to achieving a space-saving form factor • Mi...

    I want to turn a concept for a pneumatic actuator into a working prototype that can grip or clamp objects with repeatable, controllable force. The job spans mechanical design, pneumatic circuit sizing, and the embedded-software layer that will let me test different grip profiles through a simple interface. Scope • Translate my sketches and performance targets into detailed CAD ready for rapid manufacture (CNC, SLA or FDM are all fine). • Select off-the-shelf valves, fittings and sensors, then size the cylinder and air supply so the gripper reaches its force and stroke goals. • Develop quick-change firmware or a ROS/Arduino node that lets me adjust pressure, speed and dwell time from a laptop while logging position/force data. • Assemble and bench-test the unit,...

    I have a couple of small IoT units here in Hamilton, ON (L9C 6A4), I need someone who can come to the house with Microchip’s IPE and the right programmers, connect to each board, and load the latest firmware. I will supply the compiled HEX files and the client will perform the test. All you need to do is bring the hardware (PICkit, SNAP, or similar), verify each flash. If you’re local, equipped, and comfortable doing house calls, let’s set a time.
