What I need: I want a custom-built, fully working physical Skylanders portal that I can place real figures and traps on, that works with the Cemu emulator on my Windows PC. It must be detected by my computer as a genuine Skylanders portal (USB Vendor ID 0x1430, Product ID 0x0150) so the game treats it as real hardware. I am not interested in software-only emulation — I want real hardware with real, placeable figures. This is a recreation of the Skylanders: Trap Team "Traptanium" portal. It's a known, documented build (Raspberry Pi Pico + NFC reader + open-source firmware), so this is execution work, not research from scratch — I'll provide a detailed technical reference doc with the exact firmware repos, wiring, and USB protocol once we connect. The finished portal must include, like the original: An open surface to place multiple figures at once A separate trap slot Color (RGB) LEDs lighting the portal area A dedicated LED for the trap slot A working speaker for in-game audio A housing that can be opened to access the internal components for future repairs or upgrades (e.g., screwed or otherwise removable panel — not glued or permanently sealed shut) Suggested approach (you're welcome to propose better): Raspberry Pi Pico running TinyUSB-based portal firmware (e.g., the open-source PicoWPortal project), an MFRC522 reader for the main figure area, a second NFC reader for the trap slot, addressable RGB LEDs, a white trap-slot LED, and a small speaker + amp — all in a custom 3D-printed/fabricated housing. Deliverables: A working, assembled portal in a custom housing with all five features above functioning in-game. Proof it works — a short video showing a real figure and a trap being placed and recognized in Trap Team running in Cemu on Windows, plus the LEDs and speaker responding. A brief written note of the firmware/version used and how to re-flash it, so I can maintain it myself. What I'll provide: My real Skylanders figures/traps for testing (or I can dump and send the data — your call). My broken original portal as a layout/feel reference (photos or shipped). A detailed technical reference document (firmware, wiring, protocol, part numbers). Two things to be aware of before you bid (please address these in your proposal): The trap slot (second reader) and the speaker (USB audio passthrough) may require extending the firmware beyond a stock flash. Tell me whether you'll use existing firmware that supports these or whether you'll be writing/extending code, and price accordingly. The multi-figure read area needs a larger or custom-tuned 13.56 MHz antenna (a stock MFRC522 antenna only reads one small spot). Tell me how you'll handle reliable reads across the surface. Logistics: Tell me if you work remotely (I ship parts/figures) or are local to South Florida (Homestead/Miami). Please quote parts cost, labor, and turnaround separately. MILESTONES: Design sign-off — parts list, wiring plan, housing concept, and confirmation of trap-slot + audio approach. (small upfront %) Working electronics (no housing) — Pico enumerates as 1430:0150, main reader + trap reader recognized in Cemu, LEDs and speaker responding on the bench. (largest %) Final assembly + housing — everything integrated in the custom enclosure, acceptance test passed, proof video + re-flash notes delivered. (final %) Acceptance criteria With Trap Team running in Cemu on Windows: a real figure on the main surface appears in-game; a trap in the trap slot is recognized; portal RGB LEDs respond to in-game color/fades; the trap-slot LED lights when expected; the speaker produces in-game audio. Proof captured on video. I have conducted research and sourced the firmware and software needed. Just need someone to source and assemble the hardware.

I'm a retired Electrical Engineer. I have designed a very basic single sided PCB in Acad LT. I'm looking for someone to take my DXF file and import into KiCad to create manufacturing files needed for JLCPCB company. Is this something you would be interested in doing?

I need an experienced contractor to take a validated design + complete brief and produce the production schematic + 4‑layer layout. The design is fully bench‑validated; you receive a complete brief (pin map, per‑block requirements, connectivity diagram, all datasheets). This is transcription + layout + production‑prep, not architecture. One revision included. The design includes an ESP32-S3 and TI Class-D audio components. The project requires expertise in PCB design and layout, particularly with these components. The final output should be ready for JLCPCB turnkey production and assembly. Must design for FCC Part 15B; ESP32 antenna‑keepout and Class‑D thermal/EMC experience required.

I’m looking for an experienced, U.S.-based electronics engineer to help me design and deliver a production-ready PCB package for a custom truck build. I have a finalized hardware specification for an automotive-grade, high-current LED controller that will live in my truck's engine bay, but I need an expert who can review my plan, critique my component choices, and handle the professional layout. I want a true partner for this project—someone who can look at my spec sheet and say, "Hey, this looks great, but we should tweak this component or shift this trace to make it safer and more reliable." The Project Highlights: Power Handing: The board needs to safely manage 38.5A continuous at 12V DC. I'm looking for solid thermal management, proper trace width math (IPC standards), heavy copper selection (2-oz minimum), and unmasked power planes. The Brains: An ESP32-S3 microcontroller driving ~1,000 RGBW pixels. We'll need clean isolation so high-current switching noise doesn't interfere with the MCU. Protection: Optical isolation (optocouplers) separating the logic side from the high-power switching side. What I Need Delivered: Complete schematic capture, layout, component validation (with exact manufacturer part numbers for the factory), and a 3D STEP model so I can ensure perfect clearance inside a custom enclosure. I would prefer the final files delivered in Altium Designer. About You: I'm looking for one person who can own this design from start to finish. If you have real-world experience with high-current electronics or rugged automotive environments, I'd love to chat. I respect your time and expertise, so please share a realistic turnaround time and a flat, fixed-scope quote based on these parameters. Looking forward to collaborating with you!

I have a small PCB (40x30mm with approximately ~20 soldered components on it. The PCB was originally designed for a 5V power supply, so that is the voltage going to the MCU (Which is rated for a maximum operating voltage of roughly ~3.6V). I want to adjust the circuit so the 5V becomes a steady 3.3V. I am assuming with a TL431 shunt or a TPS7A02 LDO. I need someone who can interpret the schematic and confirm what can be tweaked or added to provide that steady 3.3V to the MCU. Ideally I'd like someone who can simulate the PCB to confirm the proposed modification would work, and then I need the PCB modified with this change and gerbers + BOM + pick and place provided so I can produce the new PCB.

I run a small electromechanical engineering firm and design my own control electronics. I've taken three board projects through two prototype spins each and hit walls I can't isolate on my own. I'm not looking for a redesign or finished files — I do my own design work. I need an experienced hardware engineer to review my schematics, tell me what's wrong, and tell me what to change. I implement from there. The three boards: 1. Speed control board (Gen 2) — drives an off-the-shelf motor speed controller with a variable speed signal. On the built boards, the variable speed isn't actuating at all. Also has a prox-driven error circuit. 2. Sensor interface board — 5V in, boosted to 12V, optocoupler returns the signal to keep my core system at 5V. Regulation/signal problems on the fabricated boards. 3. Main Arduino Mega control board — Mega 2560 Pro based; 5V→12V on-board conversion to power field boards, 5V distribution, optocouplers for signal conditioning, and a Cat6-style HMI connector on a hardware serial port. Where I keep missing: I'm strong on the firmware and system side but self-taught on PCB design, and my misses cluster in a few places — interface mismatches between my output stage and off-the-shelf parts (signal type/level, shared grounds), switching-regulator layout (feedback divider, loop area), and optocoupler circuits (LED resistor sizing, logic inversion). On the built boards some functions work and others are dead, and I haven't been able to fully isolate why. I need someone who can read a schematic and reason through that quickly. I work in EasyEDA and fab through JLCPCB. You don't need to own EasyEDA — I can export schematics and layouts as PDFs or standard formats. What I need is clear, specific direction on what to fix and how.

Task list for my project: 1. Desolder wires from the depleted batteries. 2. Solder in new batteries. 3. Leave a little extra wire at both ends for easer disassembly next time it's needed, to avoid the ends breaking away from their solder points. 4. Do not desolder any wires from the small round sensor with tiny LED. 5. Avoid the wires breaking free from the end with the threads. If it happens, remember how they're soldered, so they can be replaced. 6. Clean all soldering areas, especially the end with the threads. 7. Insert into the provided sleeves, with the writing on the tube placed at the end with the sensor, not at the end with threaded cap. 8. Test each one to ensure the LED end lights up, and they provide good vapor (this must be done by drawing air from the mouthpiece covering the atomizer that screws onto the end with the threads.) 9. Make sure each unit charges (the LED on the charger will be red until charging is completed, then it turns green when finished.) The LED end of the device also turns red while charging, (and it turns off when charging is completed.) *There are two black wires; one that runs from the battery to the tiny circuit board, and the other that runs from the battery to the end with the threads. There is one red wire that runs from the battery to the tiny circuit board. There is one yellow wire that runs from the tiny circuit board to the opposite end to attach to the cap with the threads. *I will send all parts needed for testing, but I will also need them back. *I will not send the small caps that go onto the end of the battery sleeves, as those aren't necessary for testing. They just serve as an LED cover to give them more of a realistic look. I'd rather put those on myself upon getting the devices back. I have two units I will send partially assembled, so you'll have a visual of how they get put back together, but they will also need a battery change. I have disassembled all the other ones, so you don't have to do it.
