The bannisters around my slightly raised floor section have too much flex and pops out/snaps, so I need them removed and replaced with a sturdier timber set that keeps the same overall look. Material must be solid wood, built and fixed so there’s no give at all once installed. I want a painted finish; the primer and under-coat should be supplied by you, and I’ll provide the exact blue top-coat that matches the rest of the room. If you prefer to leave the final colour coat to me, just let me know—otherwise feel free to paint it on while you’re here. We would prefer if someone could come in first and quote for the job and measure the space. Key points to cover: • Measure on site, replicate similarly the current profile and spacing. &bull...

...need a production-ready printed circuit board for a compact consumer-electronics tracker. The board has to combine Bluetooth connectivity for smartphone pairing, GNSS positioning for global location data, a LoRa module for long-range updates, and a 3-axis motion sensor to wake the unit only when it moves. Everything will run from a single rechargeable battery, so careful power budgeting and a low-power microcontroller are essential. Form-factor will be small enough to slip into a key-tag style enclosure, so component height and antenna placement must be considered from the start. I’m flexible on the exact silicon—Nordic, Espressif, STM, Semtech, etc.—as long as you can justify part choice against current draw, cost and global availability. Please take the d...

I’m refining a set of custom boards that combine an FPGA-based signal generator with several ESP32 modules. The immediate gap is in analog and digital circuit design: I need a fresh set of eyes to review, debug, and improve the front-end and conditioning stages so our multi-channel waveforms stay clean from kHz up into the low-MHz range. You will also find yourself touching the programmable logic; I use both VHDL and Verilog, so fluency in either (or ideally both) is welcome when tweaks to the signal-generation core are required. On the microcontroller side each ESP32 handles data processing, manages communication protocols, and drives attached peripherals, all written in C/C++. Expect to dive into that firmware whenever hardware changes ripple upward. Key objecti...

Please size all resistive dividers, isolation devices (if required), and any signal-conditioning stages so the microcontroller’s ADC receives a clean, scalable signal. What I expect from you • Complete schematic, preferably drawn in KiCad or Altium, showing the microcontroller, voltage sensor path, power supply rails, and any filtering or isolation you recommend. • Short bill of materials with part numbers that are actually availa...

I need a production-ready circuit and compact PCB built around the ESP32-C6 for an IoT device that must run efficiently on both a small solar panel and a rechargeable battery pack. Wi-Fi connectivity is mandatory, and every part of the design has to prioritise ultra-low power consumption so the unit can sit in deep-sleep most of the day yet still wake to trigger a miniature solenoid valve on command. Power architecture The board should accept solar input (≈5-6 V) and seamlessly switch to a lithium cell when sunlight is unavailable. Please integrate an MPPT-style charge controller, battery protection, and a low-loss power-path so the ESP32-C6 always sees a stable 3 V3 rail. Current draw during sleep should stay well under 30 µA.

I have a completed audiophile phono-preamp in ExpressPCB+ — schematic and two-layer board — that I now need recreated in Fusion 360 Electronics. The circuit holds 33 unique parts (about 120 total) and follows a simple structure: one power-supply section repeated six times and two identical audio channels. Because of this repetition, copy-and-paste inside Fusion should accelerate the job. All manufacturer part numbers are ready to drop straight into the new library, so you will not have to hunt for footprints or symbols. Trace widths and clearances can remain at Fusion’s defaults; no additional design-rule tuning is required. We will also keep the layer count exactly the same as in the ExpressPCB+ file. Mechanical constraints are critical: • Overall b...
