# Prototype Brief — Handheld Force-Sensing Probe ## Summary I need a working prototype of a small handheld instrument that measures the contact force applied through a thin rigid probing tip. When the tip is pressed against a surface, the device reads the applied force in real time and signals when a target force is reached. All sensing and electronics stay inside the handle; the tip itself is a slim passive pin. This is a proof-of-concept prototype, not a finished product. Priority is a fast, cheap, working demonstration. ## How it works (concept) - A thin, rigid probing tip is mounted on a shaft. - The shaft is free to slide a tiny amount (roughly 0.1–0.3 mm) inside the handle against a light preload spring. - Pressing the tip transfers axial force to a force sensor housed...

I need help bringing a single-layer PCB back to life. At the moment it shows three clear problems: several components have failed, some traces are visibly damaged, and the board refuses to power up consistently. I can supply the original Gerber/layout files, but the schematic is no longer available, so part of the task will involve tracing the nets and inferring the missing circuit details. Your job is to: • Pin-point every faulty component and specify equivalent replacements • Locate and mend any open or shorted traces, or propose jumper fixes where copper is beyond repair • Restore a clean, stable power rail and verify correct voltage levels under load • Give me a concise repair log that includes measurements, photos of each fix, and final functional tests A ...

I have an online electrical and safety course that shows more 100 separate modules still outstanding. Everything is already built—short videos followed by a quiz in each section—so the only job is to work through them until the platform records every module as 100 % complete. You will receive my login, move at your own pace, and mark each quiz successfully. No writing, design, or extra content is needed; I simply need the course dashboard to read “completed” across the board. When you are done, send a quick screenshot or export of the completion page so I can keep it for my records. That’s all there is to it.

I have a working concept for an E-Rickshaw diagnostic tool based on an ESP32 DevKit V1, and I now need a production-ready 2-layer PCB. All circuitry must operate from the vehicle’s 48 V line, stepped down via an LM2596. The board will drive an I2C OLED, measure battery voltage, and sense individual lines for the horn, headlight, indicators, brake light, and reverse buzzer. Two probes (A & B) are included for quick continuity tests. Good engineering practice is mandatory: reverse-polarity, fuse, TVS and general input protections must be designed-in. Preferred workflow • KiCad is my first choice; if you feel EasyEDA delivers clear advantages, let me know. • Layout decisions should favour ease of assembly over sheer compactness or extra thermal tricks. • Blueto...

Please note: Max payment for this is $180. Please do not bid and then negotiate higher price if this is not acceptable. I need a KiCad project that lays out a compact, dual-rail power supply capable of delivering up to 10 A per rail at a maximum of 70 V.

I need a working human-computer interface that can both pick up and broadcast data over Bluetooth at the highest speed the protocol allows. The data flowing through it will be full-rate cellular communications data rather than simple audio or text, so throughput and low latency are critical. On the input side the unit will read Qi energy and Acu-meridian energy via harness-style skin contacts. Those raw sensor signals have to be conditioned, digitised and pushed straight to a tablet over Bluetooth without noticeable lag. In the opposite direction the tablet will be able to transmit control or stimulation patterns back to the interface just as quickly. The job covers hardware design, embedded firmware and a basic demo app for a tablet or computer: • Hardware: schematic, PCB layout an...

Please Note: total amount is $80. Please do not bid if this is not acceptable. I’m putting together a single-rail power supply for sensitive audio gear and need a clean, hum-free output.
