capacitive encoder

Big Clive tears down a cheap eBay digital caliper, explaining its capacitive linear encoder and measuring its quiescent current. He finds it surprisingly accurate and repeatable for its price.

Disney Research presents Touche, a swept frequency capacitive sensing technique that recognizes complex hand and body configurations, and adds touch sensitivity to humans, liquids and everyday objects.

A Two Minute Papers episode on NVIDIA's recurrent denoising autoencoder, which cleans up noisy Monte Carlo path-traced image sequences. It shows how a neural network can produce usable renders from very few samples.

Technology Connections explains how touch lamps work and traces them back through patents to the 1950s, far earlier than most people assume.

A two-minute demo of SmartKnob View, an open-source input knob built from a brushless gimbal motor, magnetic encoder and round LCD. Closed-loop torque control gives software-defined detents and end stops.

Jason Cammisa reviews the 2022 Volkswagen Mk8 GTI and explains why he thinks it is worse than the Mk7. He criticizes aspects such as the capacitive touch controls and the interface.

A guest video by Welch Labs on 3Blue1Brown explaining how text-to-image and video models work. It covers CLIP, shared embedding spaces, diffusion models (DDPM, DDIM), conditioning, guidance and negative prompts.

The official music video for Despacito by Luis Fonsi featuring Daddy Yankee, a Latin pop hit that became the most viewed video in YouTube history.
