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’m putting together a small-run prototype built around an ESP32 S3, small display, micro sd card reader, speaker, and some buttons. I have much of the work completed by a previous designer, but I need help finishing it. I have a schematic, gerbers, BOM, and pick and place files - but I need help finding alternative parts that are actually in stock at JLCPCB. I also need help troubleshooting some potential design issues that Claude has found. I'm not an electrical engineer and need some hand holding to bring the project together.

I’m putting together a small outdoor rack and need an electronic sensing solution that can tell me, in real time, whether something has been placed on—or removed from—each shelf. Cameras are off-limits, so I’m looking for a clean sensor-based approach that works equally well with mixed materials such as metal, plastic, or any everyday composite an item might be made from. Because the rack will sit outside, the hardware must shrug off normal weather exposure—sun, light rain, the usual seasonal swings—but it doesn’t have to survive arctic freezes or tropical monsoons. A compact, low-power design is preferred, and I’m open to ultrasonic, IR, capacitive, load-cell, or any other sensor technology you feel is best suited to the job, provided it st...

Electrical Engineer Needed — Sundial-Inspired Rotating Light Clock What I'm Building A functional clock where a motorised arm rotates around a central post (gnomon) once every 12 hours.
