Flex circuit design jobs

Logo design for Perflo (fintech app) We're building an app called Perflo. It lets people set spending rules for automated payments, so money can move on its own without anyone losing control of it. Two ideas sit at the center of it: money that moves, and money that's protected while it moves. If a logo can hold both of those at once, that's the whole job. We need a logo, an app icon, and a small set of variants. What we're after We're not telling you what to draw. We want to see your thinking. Some of the words we keep coming back to internally: flow, agent, permission, access, boundaries, limits, control, trust, automatic. A keyhole, a channel, a gate, a valve, a card, a meter, something abstract we haven't thought of. Your call. The name is perfl...

I need three high-resolution banner visuals for an upcoming corporate event. The graphics must be suitable for flex printing, so please set them up in CMYK at 300 DPI and supply bleed marks. I’m comfortable with either CorelDRAW (.cdr) or Adobe Illustrator (.ai); just be sure all text is outlined and linked images are embedded when you hand over the files. The look has to stay formal and professional—think clean typography, restrained colour palette, and a layout that feels at home in a board-level setting rather than a trade-show carnival. I will provide the event logo, brand colours, and the exact copy once we start; dimensions for each banner will follow as well. Deliverables • Three separate banner designs, print-ready (PDF) • Matching editable sour...

I’m bringing a brand-new electronic charger to market and need an engineer who can turn my concept into a fully working prototype. The focus of this engagement is the complete design and prototyping phase—circuit architecture, component selection, enclosure layout, PCB, and initial functional build. Compact size is the single most important design driver, so every decision—from transformer topology to enclosure wall thickness—has to work toward a slimmer footprint without compromising safety or performance. I’m open to creative approaches such as GaN or other high-efficiency solutions if they help us meet that goal. To move forward, please send a detailed project proposal that outlines: • Your approach to achieving a space-saving fo...

I need a compact, reliable PCB and a compact case design. The board contains an ESP32 that will run the anchor-control logic on my boat and live inside a fully waterproof enclosure. The board must accommodate the following external connections: one USB-C port for configuration and firmware updates, a 12 V power feed (positive and negative), two independent 12 V outputs that switch through relays (max. 10A), two 12 V inputs that feed a dual-channel optocoupler, and two additional inputs coming from reed sensors. Functionally the circuit is dedicated to anchor control—nothing else—so component choice, trace sizing, and protection devices should all be selected with marine power fluctuations and vibration in mind. Please route with good separation between logic an...

I want to turn a concept for a pneumatic actuator into a working prototype that can grip or clamp objects with repeatable, controllable force. The job spans mechanical design, pneumatic circuit sizing, and the embedded-software layer that will let me test different grip profiles through a simple interface.

# FastForm Capacitive Sensor Electrode — PCB Design & Order Brief --- ## Overview I need a **very simple 2-layer PCB** designed and manufactured. Two variants, 5 boards each. **This board has no components, no traces, no schematic, and no routing.** It is four copper rectangles and three vias. Someone competent with KiCad should complete the layout in under an hour. **Important context so the design decisions make sense:** this is not a normal circuit board. It is a **capacitive sensor electrode** that will be immersed in wet concrete. The **solder mask is a functional dielectric layer**, not a cosmetic finish. Several instructions below will look unusual for a PCB — please follow them exactly rather than applying normal PCB conventions. --- ## D...

I need help bringing a single-layer PCB back to life. At the moment it shows three clear problems: several components have failed, some traces are visibly damaged, and the board refuses to power up consistently. I can supply the original Gerber/layout files, but the schematic is no longer available, so part of the task will involve tracing the nets and inferring the missing circuit details. Your job is to: • Pin-point every faulty component and specify equivalent replacements • Locate and mend any open or shorted traces, or propose jumper fixes where copper is beyond repair • Restore a clean, stable power rail and verify correct voltage levels under load • Give me a concise repair log that includes measurements, photos of each fix, and final functional te...

The square wave should have an equal mark-to-space ratio, a frequency equal to that of the resonant frequency of the metal bar estimated in Part 1, and an output voltage going from 0 volts to +15 volts. Show full working for calculating component values and draw the circuit diagram. Part 1 is measure the frequency response of one of the metal bars from the Electronics Lab. You will need to use the signal generator (function generator) and oscilloscope to do this. Plot the resulting frequency response across the range 100kHz to 200kHz, and state the resonant frequency of the metal bar.

GPIO pin mapping, level-shifting, protection, and a clean 3 V3 rail must all be worked into the schematic. Please route with sensible trace widths, keep EMI in check, and leave me a little proto area for future tweaks if space permits. Deliverables • Schematic and well-annotated PCB layout &...
