I’m putting together a short Brazilian analog-horror piece and need a CGI creature that shows up only a handful of times—each appearance lasting roughly 2–10 seconds. The setting alternates between a dimly lit house, where we see the creature only in fragments, and empty nighttime streets, where it is shown in full. Creature brief • Scale & posture: humanoid, about 2.5 m tall, arms so long the hands brush the ground. • Face: a smooth, mask-like surface; instead of eyes, readable words glow or flicker, adding to the unsettling analog-tape vibe. • Mood: the design should feel unmistakably eerie and in-universe with retro VHS artefacts—think scan lines, color bleed, and slight frame jitter. Scope of work 1. Concept refinement ...
...for discussion once the basic framework is proven. An Arduino-class board running Python (CircuitPython or MicroPython is fine) will sit at the center of the design. Core behaviour • A proximity sensor with a simple NO/NC or other switched-DC output tells the microcontroller when the vehicle is near its target. On that event the code must turn the devices on or off, make or break the live analog video path, and if required trigger visual or audible alerts. • A vibration/accelerometer module tracks motion. When the vehicle has been still for a preset timeout the controller should cut power to all three devices, blink a “sleep” pattern on an LED, and enter a deep-sleep state to save the battery. Once vibration resumes the system must wake cleanly and ...

I’m running a Teensy 4.1 that delivers a 0 – 3.3 V square wave at 80 kHz. For my signal-transmission stage I must boost that logic-level waveform to a clean +6 V amplitude, powered from an existing 13 V rail. Because the downstream chain mixes analog and digital circuitry, frequency stability, waveform accuracy, and strong noise immunity are all critical; edges need to stay sharp without ringing or overshoot, duty cycle must remain intact, and added jitter should be negligible. Here’s what I’d like from you: • A proven conversion topology (discrete driver, high-speed op-amp, gate driver, or any suitable approach) that takes 0 – 3.3 V in and produces a solid +6 V square wave at 80 kHz. • Schematic with full component values, part numbers, a...

Title: Fatek PLC Slub Yarn Pattern Fix — LFSR Randomization (WinProladder, urgent) Description: We have a thick-and-thin yarn machine controlled by a Fatek FBs-series PLC (WinProladder). It has a FBs-2DA analog output module that sends 0–10V speed commands to two VEICHI VFDs (DRAFT/1 and DRAFT/2) via registers D3840 and D3841 (0–4095 = 0–10V). The problem: The current program uses a fixed step table that repeats every ~1.5m, causing a diamond pattern in woven fabric. The spec requires no repeat within 1000m. What we need implemented — exact spec: Two independent 16-bit LFSRs in ladder logic: LFSR-1 for Roving 1: state in D100, mask K46080 LFSR-2 for Roving 2: state in D110, mask K53256 Period = 65,535 — never repeats within 1000m No step tabl...

The sensor gives me an analog output, but by the time it reaches the ESP32 GPIO the waveform is unusable. I need a complete hardware solution that delivers a rock-solid, noise-free signal to the microcontroller. Your work should cover the full pathway from the sensor connector to the ESP32 pin: component choices, protection stages, filtering, and grounding strategy. If shielded cabling, ferrite beads, or optical isolation prove helpful, feel free to weave them in; the key is a verifiably clean edge at the micro. I have attached video where pnp is installed Please provide: • Schematic with reference designators an...

...plastic molding - Knowledge of mold-making techniques - Ability to create custom designs I have the exact dimensions and specs required for the handle. The design would only have to be for 1/2 of the handle as it would be printed twice to make the whole. In the old days we used to make analog molds from a plug but people have been successful using 3d printing, I just don't have the skills. There are several other minor features which can be discussed later. I've attached a couple photos of a traditional analog handle mold for reference. Overall size of mold would be approx 10"x4"x3" (two pieces) so each piece would be roughly 1.5" thick. I'm unsure the best material for the mold but it must be strong (handle is molded urethane foam under...
