PCB Layout Jobs

I need a very straightforward device that can be bolted onto my 10-ton and 20-ton power presses and register every single-direction stroke. Each time the ram comes down, the unit must fire an outgoing webhook to my server that carries two data points in the payload: the cumulative stroke count and an exact timestamp. Simplicity is key—no sophisticated HMI, just reliable sensing, basic edge processing if needed, and an Ethernet or Wi-Fi module (your choice) that can hit an HTTP / HTTPS endpoint I will supply. Please choose whatever cheap, readily available sensor and microcontroller make the most sense; I care more about durability and ease of replacement than brand names. Deliverables I’m expecting • Schematic, parts list and enclosure suggestion suitable for the 10 t ...

I have five DVD recorders, each with its own internal tuner, yet none of them will currently lock on to the usual UK Freeview channels (BBC, ITV, Channel 4, Channel 5, and the rest). What I need now is clear, practical guidance that will get every unit reliably receiving those services again. Here’s the situation so far • All five recorders report a tuner, but they either return “no signal” or pick up only a handful of shopping channels. • I’m uncertain whether all machines are sharing the same aerial feed or if each has ended up on its own run of coax. • I’m open to adding an external solution—splitter, signal amplifier, standalone Freeview box, whatever makes the most sense—but I’d like your recommendation before I buy...

I am refreshing a legacy product that once ran on a discontinued Cypress CY7C series. The only artifact that survived is the compiled HEX file, original schematics; the original codebase is long gone. Our new PCB is complete and waiting for firmware that reproduces—and, where sensible, improves—the original behaviour. Your task is to analyse or re-implement the HEX, then build a clean, well-documented project in PSoC Creator 4.4 that runs flawlessly on the new hardware. Core functions that must carry over are the existing communication protocols, sensor integrations, and power-management logic. I can supply the old HEX, the original schematic, and the new schematic as soon as we agree on scope . Deliverables • PSoC Creator 4.4 project with full source, organised for ongo...

I am rolling out a small-scale industrial automation rig that runs on an Arduino Mega driving seven 12 V linear actuators through BTS7960 H-bridge modules.

I need engineering support to complete the last missing piece of a household product that is otherwise fully designed: the LED system. Your assignment is to create a compact housing that secures a short LED strip to the product’s internal frame, mates cleanly with an existing lithium-ion battery pack and still allows users to run the lights from the battery or bypass it by plugging into mains power. Material choice that it will be attached to is either a resin mold or a plastic-injected mold. The final design must be manufacturable at scale. Because the LEDs sit behind an opaque panel, the external form factor is not constrained by aesthetics; what matters is thermal management, ease of assembly on our current chassis and clearance for existing screw bosses. Internally the LEDs must...

I want to field-test a single, fully-functioning prototype that logs freshwater temperature and depth, stores up to 256 paired readings, and beams everything to a small handheld receiver once the float surfaces. Hardware parameters are already fixed.

The board has to respect strict size limits—I’ll provide the exact outline, keep-out areas, and mounting points as soon as we kick off—so smart component placement and tidy routing are critical. Both through-hole headers and surface-mount parts will appear on the design, so you’ll need to balance mixed-technology footprints without compromising manufacturability. I can supply the complete schematic, component datasheets, and the mechanical drawing; what I’m missing is the finished PCB artwork and fabrication files. Deliverables once we’re done: • Editable PCB design file in your preferred tool...

I’m developing a compact, handheld industrial device and need a PCB engineered specifically for that environment. The board must house a central microcontroller and an integrated battery pack circuit, with no wireless modules required.
