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 need a clean, ready-to-build schematic for a compact keyboard that uses an Arduino Micro as the controller. The board is for everyday, general use and will be arranged in a 3-row by 3-column matrix, with an additional key to switch between 4 modes. (10 keys in total). Hot-Swap Keyboard for the keys. Add diodes Include a 2 layer LCD Display that can be programmed on the Arduino Pro Mirco. Besides the usual character input, I want a few of those keys assigned to media functions—play, pause, volume up/down—and a couple reserved for custom macros. If you include diode placement and a clear pin map from the key matrix to the Arduino Micro’s GPIO pins, that will make firmware-writing straightforward on my side. PCB must be spaced to fit a 3d Printed enclosure Please del...
I need a compact acquisition board that reads pressure sensors and sends data by Bluetooth and Celullar (SIM). Your job covers both the hardware and the embedded layer that will live on the board. System Requirements : A custom PCB (embedded system) must be designed to interface with the sensor. The system will be powered by an external battery, for which voltage and current requirements must be carefully calculated. The PCB will receive pressure data from the sensor through front-end components directly connected to the electrode outputs. A microcontroller (MCU) will scan the matrix at high frequency by sequentially energizing one electrode (e.g., rows) and measuring responses across perpendicular electrodes (e.g., columns). This scanning process allows detection of pressure points acros...
I need a complete hardware-to-firmware solution for a low-power, standalone temperature and humidity monitor that relies on 4G/LTE rather than Wi-Fi. The core will be an ESP32 driving a SIM7600G module, paired with a DHT22 sensor. Collected readings must be published over MQTT to my Supabase/PostgreSQL back-end. The device will sleep most of the time, wake on schedule, take a reading, push it securely, then drop back into deep sleep. It also has to recognise a lost cellular link, attempt reconnection gracefully, and log any failures for later review. Power comes from a Li-po pack, topped up through a USB-C port, so the design needs an efficient charging and protection stage. Please deliver: • Complete, readable schematic (PDF + source) • Production-ready PCB layout with G...

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 need a compact hand-held controller that combines a dead-man safety switch with a rotary potentiometer and feeds a clean PWM signal into an Arduino-based drive system for an axial flux motor traction inverter. When the side button is depressed, the rotary pot should dictate motor speed; the instant the button is released the output must drop to the same state as an e-stop, guaranteeing zero drive. The housing has to be fully 3D printable on a typical FDM printer (200 × 200 × 200 mm envelope, PLA or PET-G). Ergonomics matter—I’m picturing something that can be gripped like a bicycle throttle with the thumb naturally resting on the kill switch—but feel free to propose alternatives if they remain compact and printable without supports in awkward internal cav...
I’m building a small interactive sound board driven by an Arduino and the MPR121 capacitive-touch controller. Between five and eight copper-tape pads will act as the touch points; the moment any pad is tapped it should fire a single, corresponding MP3 track through a DFPlayer Mini, then stop—no looping, no timed fades. Here’s the workflow I need solved: • Code that links each of the MPR121’s channels to its own MP3 file and plays the file once per touch, with simple debouncing so accidental retriggers are avoided. • Reliable wiring that ties the Arduino, MPR121, DFPlayer Mini, a small Class-D amplifier and speaker together, plus a spare GPIO line that can mute the speaker and divert audio to a 3.5 mm headphone jack when a plug is detected. • Eve...
Our processing line needs a reliable counting routine, written in CODESYS, that records the exact number of chickens immediately after slaughtering.

Clean, well-structured, compi...
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...

I have an ESP32 Basic Core IoT Development Kit V2.7 installed in my truck and need firmware that will warn me whenever the Starlink router stays powered after I switch the ignition off. The sketch should watch a dedicated ignition-sense pin: while the line is high the unit does nothing special, but as soon as it goes low it must keep polling the Wi-Fi connection status in code. If the ESP32 is still associated with any network after a user configurable amount of time, an on-board LED must begin to flash, screen starts flashing and the internal speaker must chirp in tandem until the Wi-Fi link drops or the ignition is restored. I would like a simple LCD screen interface on the kit’s I²C display that shows real-time states (“Ignition ON / OFF”, “Wi-Fi CONNECT...
