I want a small, low-noise pre-amplifier built around the NE5532, powered from + - 15v. The board will slot straight into my DIY projects, so please place the op-amp in an 8-pin DIP socket for easy swapping and surround it with proper rail filtering and local decoupling: • bulk filter capacitors on each rail (before and after any regulators you choose) • 100 nF ceramics tight to every NE5532 supply pin I need two input connection styles on the same PCB—standard RCA jacks plus snap-on terminals—so the preamp can drop into other snap-on equipped modules without adapters. Output may remain RCA only. Deliverables • Complete schematic in your preferred CAD package (KiCad, Eagle, or Altium are all fine) • Clean PCB layout and production-ready Gerbers with ...

need a straightforward 2-bit counter designed entirely with discrete Bipolar Junction Transistor (BJT) logic. My priority is to keep the component count as low as practical while still delivering clean, glitch-free counting through the four binary states (00-01-10-11). • Use only BJTs – no FETs, ICs, or microcontrollers • Favor the fewest possible transistors and passives without compromising function • Standard 5 V logic levels are ideal, though I’m open to 3.3 V if that helps reduce parts Ultimately, the most important thing is that the design works practically on the breadboard—without issues and without noise.

I have a consumer-electronics board that combines both surface-mount and through-hole parts and now needs full turnkey assembly. I will supply the BOM, centroid/PnP file, and all component datasheets.

# Prototype Brief — Handheld Force-Sensing Probe ## Summary I need a working prototype of a small handheld instrument that measures the contact force applied through a thin rigid probing tip. When the tip is pressed against a surface, the device reads the applied force in real time and signals when a target force is reached. All sensing and electronics stay inside the handle; the tip itself is a slim passive pin. This is a proof-of-concept prototype, not a finished product. Priority is a fast, cheap, working demonstration. ## How it works (concept) - A thin, rigid probing tip is mounted on a shaft. - The shaft is free to slide a tiny amount (roughly 0.1–0.3 mm) inside the handle against a light preload spring. - Pressing the tip transfers axial force to a force sensor housed...

I want to bring a compact, consumer-friendly utility gadget to market and need an engineer who can take it from idea to production.
