I have fifteen disassembled original first generation "cigalike" e-cigarettes waiting for fresh new cells. The spent batteries still have to come out; I’ll supply the brand-new replacements along with step-by-step instructions I’ve written from my own repair notes. Once each cell is tinned and soldered, the board and wiring need to slide back into the original metal tubes that I will ship with the lot. After reassembly I need every unit verified for both firing (making sure the LED end eliminates, and it produces vapor,) and charging. A simple functional puff/hit-to-vape check is the first pass, then confirmation that each battery takes and holds a charge using a charging USB that I will provide. If anything reads off, I’d like a quick note so we can decide whe...

I have a circuit idea that now needs to move from the sketchpad to a real-world prototype. The end goal is a fully built, ready-to-power-up PCB that I can use purely for test and evaluation.

I need a turnkey, camera-based solution that automatically counts plastic totes as they move through the rear door of each of my 100 refrigerated trucks. The goal is simple: every tote that goes in or out must be logged accurately without asking the driver to press a button, scan a tag, or slow down the loading process. Miscounts today cost real money; the new system must work in the messy, unpredictable environment of an active loading dock, not in a lab. Environment & constraints • Lighting varies from bright daylight to total darkness inside the trailer, and weather changes constantly when the door is open. • Drivers may step in front of the lens, so brief occlusion is inevitable. • Totes often travel in stacks of two to five, so the software has to identify an...

I need production-ready firmware for an STM32F303 that turns the microcontroller into a front-end for high-speed digitisation of SDR signals. The chip’s ADCs must sample the incoming RF-baseband stream, move the data through DMA with minimal latency, and prepare it for onward transmission over a fast serial link (either SPI or UART—whichever achieves the cleanest, sustained throughput on this part). The core of the job is sensor-style data processing: capture, buffer, and pre-format the raw samples so that an external host can handle the heavier DSP. No motor-control, no classic temperature or pressure sensors—just clean, reliable handling of SDR-grade analogue input. Key expectations • Continuous, gap-free acquisition at the highest practical sampling rate for t...

I have a Delta PLC-based machine that needs a clean, function-focused interface built around five separate screens, exactly as laid out in the document I’ve attached.
