Hi there, I carefully read your project description, and I can help create a simple, safe electrical design to power both the USB neon sign and the additional 12-LED section from the same 5V USB source. I’m Samuel Tshibangu, a mechatronics engineer with hands-on experience in LED circuits, low-voltage power distribution, current limiting, PCB/protoboard wiring, and compact embedded lighting designs. I’ve already worked with similar USB-powered LED systems, so I can design a clean solution that keeps current within safe limits and does not affect the neon sign behavior. I can provide a clear schematic, resistor/current-limiting calculations, parts list, wire gauge recommendations, and resin-specific assembly notes for insulation, moisture protection, heat-shrink placement, and low-profile embedding. Feel free to send me the LED specs and neon sign current rating so we can finalize the design. Best regards, Samuel Tshibangu

@hamzazayyad

Dear Sir, I have good experience in LED power design, USB-powered circuits, and compact embedded electronics for decorative and resin-art applications. I can design a clean, reliable solution that safely powers both your existing USB neon sign and the additional flicker/steady LED section from a single 5V USB source. For your project, I will provide: • A complete schematic showing proper USB 5V power splitting • Correct resistor/current calculations for the 12 LEDs • Separate handling for flicker LEDs and the constant-on LED if required • Current-budget verification to ensure safe operation from standard USB power • Compact low-profile wiring suitable for resin encapsulation • Recommendations for wire gauge, resistor package size, and protoboard layout • Resin-specific protection notes (heat shrink, strain relief, insulation, moisture protection, thermal considerations, etc.) I can also evaluate whether a simple constant-current stage or small DC-DC solution would improve brightness consistency while keeping the build compact and easy to solder. Deliverables: 1. Clear schematic PDF/image 2. Parts list with values and recommended packages 3. Short practical assembly guide for resin embedding I focus on designs that are electrically safe, easy to assemble, and realistic for real-world crafting—not just theoretical schematics. Best regards, Hamza Electronics Engineer

@yaroslavmark

Hi, your resin-art lighting project is a great fit for my background in low-voltage electronics, USB-powered embedded circuits, and compact custom LED integrations for enclosed installations. I have 10+ years of electronics design experience and completed 100+ small-form-factor lighting and embedded power projects involving USB power distribution, current-limited LED circuits, thermal management, and compact hand-assembled prototypes. Approach ✅ I will design a clean 5 V power-distribution circuit that safely powers both the existing neon USB sign and the additional flicker/steady LED network in parallel without exceeding USB current limits. ✅ I will calculate resistor or constant-current values for stable LED brightness, balanced current draw, and minimal heat generation while keeping the assembly compact for resin embedding. ✅ I will deliver a clear schematic, concise BOM, and resin-specific assembly notes covering wire selection, insulation, strain relief, moisture protection, and low-profile protoboard layout recommendations. Questions ✅ What is the measured current draw of the existing USB neon sign so I can verify the remaining current budget for the LED section? ✅ Are the 3 V LEDs standard through-hole parts or SMD types, and do you already have their forward-current specifications? ✅ What approximate physical space is available inside the resin casting for the hidden electronics and wiring section? Best, Yaroslav

Hello sir I have 11 years of experience as a Senior Electrical Power Systems & MEP Design Engineer leading a multidisciplinary freelance engineering team. I have engineered a complete, production-ready parallel distribution circuit to seamlessly integrate your twelve 3 V LEDs with your existing 5V USB neon sign. The design guarantees zero behavioral interference with the neon sign while maintaining an ultra-low thermal profile optimized for safe, long-term resin encapsulation. The principal technical challenge in casting active electrical components into dense resin is thermal accumulation and moisture degradation. Epoxy resins act as thermal insulators; therefore, any excessive voltage-drop dissipation across current-limiting components can cause high-temperature localized boundaries, degrading the resin matrix or causing premature LED failure. Our solution resolves the data-to-fabrication transition by executing an Integrated Micro-Spatial Resistor Matrix Strategy directly at the primary 5 V DC bus split. By assigning independent, precisely calculated current-limiting resistors to individual parallel LED branches, we minimize localized heat generation and distribute thermal dissipation evenly across a flat protoboard footprint. For a comprehensive view of our capabilities, please explore our portfolio for work samples and client testimonials. Regards, Eslam

Dear Client, The biggest risk in this project is not connecting additional LEDs to a USB-powered neon sign. It is creating a circuit that causes voltage drops, uneven brightness, overheating, or reliability issues once everything is embedded permanently inside resin. That is where practical low-voltage lighting and embedded electronics experience matters. I would approach this by: ✅ reviewing the neon sign power characteristics, LED specifications, and total current requirements to determine the safest and simplest power distribution method ✅designing a compact low-profile circuit including proper resistor/current-limiting selection, USB power splitting, LED grouping strategy, and protection considerations for stable operation My experience includes USB-powered circuit design, LED driver and resistor calculations, low-profile embedded electronics, resin-art electronics integration, low-voltage lighting systems, prototype circuit development, compact solderable circuit layouts, and thermal & power management. One key question: Do you already know the approximate current draw of the existing neon USB sign, or should the first phase include verifying the available USB power budget before integrating the additional LEDs? Message me and I’ll help create a simple, reliable, and resin-friendly lighting solution that looks clean and performs safely once permanently encapsulated. Best regards, Prat PCB Must Innovations

Best USB Resin Art Lighting Circuit Design Expert ⭐⭐⭐⭐⭐ Hi, When I saw your USB Resin Art Lighting Circuit Design requirement, it reminded me of several USB-powered LED and compact lighting projects I’ve delivered — including low-power LED driver circuits and decorative lighting systems powered safely from a single 5V USB source without affecting existing loads. This type of work is not just LED wiring — it requires proper USB 5V current management, correct resistor/driver selection for flicker and steady LEDs, and safe parallel integration so the existing neon USB sign continues working normally inside a resin-embedded design. ✅ I have 11+ years of experience in embedded electronics and low-power circuit design, including USB-powered devices, LED driver circuits, and compact consumer electronics prototyping. ✅ I can design a complete schematic, BOM, and practical assembly guidance suitable for resin casting. Before proceeding, may I clarify: 1. Do you want natural flicker LEDs or controlled pattern-based flicker? 2. Do you prefer a simple resistor-only design or small driver ICs for better control? Two quick suggestions: ✅ Use separate current limiting for each LED group for stable brightness ✅ Keep total LED current under ~80% of USB limit (≈400 mA max for safety if standard USB port) Freelancer doesn’t allow me to message first — happy to help you build a stable USB resin lighting design. Kind regards, Avi Gupta Quality is never an accident

@patrickA123456

╰(*°▽°*)╯Hi there,??? I have a question for your project: What type of USB power source should the circuit be designed for — a standard USB 2.0 port (500 mA), USB 3.0 port (900 mA), or a higher-current USB wall adapter in the 1–2 A range? I can design a simple, low-profile circuit that splits the USB 5 V line cleanly, keeps the neon sign isolated from LED load changes, and uses proper current-limiting resistors or compact drivers for the flicker and steady LEDs. I’ll provide a clear schematic, concise parts list, resistor values, wire gauge recommendations, and resin-specific assembly notes for heat-shrink, insulation, moisture protection, and clean embedding. The design will stay practical for small protoboard soldering while keeping current draw within a safe USB range. I can also include a smarter current-management option only if it improves reliability without making the build unnecessarily complex.
