I need a complete engineering package for a compact, stainless-steel (SS316) system that transfers two high-pressure gases—oxygen and a second gas—from 4 L, 1 800-2 000 psi supply cylinders into a 5 L storage tank. The small tank will serve purely for storage. Filling must occur in a defined sequence: first oxygen to a set intermediate pressure, then the second gas until the vessel reaches roughly 1 000 psi total. Gas purging is the preferred method for every line before and after each fill so that no pressure or cross-contamination remains prior to disconnecting the storage tank. The layout has to stay very tight—short runs only—and all wetted parts are to be SS316. Control and safety monitoring will be handled through a PLC with an HMI. Plan on integrating: &b...

I’m building a microcontroller-based system around an stm32 and need compact, reliable embedded-C firmware that lets me read multiple sensors and move their data cleanly through standard communication channels. The core of the job is classic microcontroller programming: bring up the chip, initialise the peripherals that the sensors require (typical I²C, SPI or simple GPIO timing), perform periodic reads, apply any basic filtering the devices recommend, then expose the results over the communication protocols we agree on—UART is mandatory; CAN or USB-CDC would be a welcome extra if time allows. You will be working with the latest STM32CubeIDE tool-chain, so please be comfortable with HAL and, where efficiency demands, direct-register work. I’ll supply full pin-outs, ...

The original schematics and firmware sources for my existing motherboard are no longer available, yet I still need to keep the product alive and solve a series of recurring hardware failures. The immediate objective is to reverse-engineer the board in detail so I have a complete, accurate picture of how every power rail, I/O interface, and embedded controller is wired and programmed. Once that knowledge is captured, I want a refreshed design that removes today’s failure points and is ready for a short production run. Work starts with non-destructive teardown, high-resolution imaging, net tracing, and firmware dumping via JTAG/SWD or any other proven technique. From there the task moves into schematic recreation (Altium Designer or KiCad preferred), BOM generation with current compon...

I’m putting together an all-terrain rover that pairs a Raspberry Pi 5 with an Arduino. The Arduino will sit close to the hardware, polling and driving everything from temperature-humidity probes and distance sensors to an IMU (pitch/yaw/roll, altitude, compass), ESC-PWM motor controllers, speed-over-ground tracking and battery-management read-outs. All of that raw data needs to flow up to the Pi, where it is bundled, logged and pushed over a 4 G link. The Pi also runs the user interface on an onboard touchscreen. I want that interface to launch straight into a clean dashboard with drag-and-drop style widgets so I can rearrange or resize gauges, graphs and buttons while in the field. On the software side I need: • Firmware for the Arduino that publishes every sensor value pl...

I want to build a persistence-of-vision LED system that mounts on a standard bicycle wheel and shows crisp, full-color static images whenever the wheel reaches riding speed.

Your code should compile and run on the free tools from XMOS; please include any scripts or tuning utilities you rely on. Deliverables • Production-ready Gerbers, pick-and-place file, annotated schematic • BOM with supp...

I’m building a small-footprint PCB around the ESP32 that will serve as the core of several IoT devices.

I have three existing Altium Designer projects that must be refreshed before the next manufacturing run at JLCPCB. Both the schematic and the board layout need attention. On the schematic side I already know the exact edits: a handful of parts have to be added or removed, several nets must be reassigned, and a few voltage- and current-related values updated. Once those changes are in place the PCB layouts have to be brought in line—rerouting where required, keeping the original board outlines and mechanical constraints intact, and making sure every DRC/ERC check comes up clean. When the files are solid I need a full, ready-for-upload manufacturing package: • Updated Altium project files (.PrjPcb, .SchDoc, .PcbDoc) • Gerber and NC-Drill set generated with JLCPCB’s ...
