Animator Joel Haver explains how he makes his short films using rotoscoping and the EbSynth tool, along with the software he uses. The method is a labor-intensive, frame-by-frame process.

The UK DVSA's one-minute guide to the hazard perception part of the driving theory test, covering when to click and how to score well.

Jerobeam Fenderson shows how to draw a mushroom on an oscilloscope in XY mode using stereo audio, then animates it by modulating with a larger wave. Pd and Max4Live patches are provided.

A roughly 10-minute guided Non-Sleep Deep Rest session voiced by neuroscientist Andrew Huberman. It is meant to reduce daytime fatigue, improve focus and aid sleep.

A short walkthrough of a hack that tricks a Brother laser printer into accepting third-party toner by working around its genuine-toner check. It notes this may void the warranty.

Andrew Huang teaches the basics of music theory in about half an hour, covering intervals, chords and patterns. He stresses understanding how music works over memorizing terminology.

Dr. Mark Cucuzzella of the Natural Running Center gives a short instructional video on natural running form. It describes the principles of good technique, including barefoot-style mechanics.

The first part of a ShaderToy live-coding series that lays the groundwork for The Drive Home, a rainy night-traffic shader. It covers basic setup and builds toward rain and bokeh effects.

In a long live-coding session, Andreas Kling works on making the Cookie Clicker game playable in the Ladybird browser from SerenityOS. He tracks down bugs in the browser engine and fixes them.

Allieway Audio gives an informal introduction and live-coding demo of ORCA, a free esoteric programming environment for building procedural sequencers from Hundred Rabbits. It walks through the interface and how to make music with it.

James Trunk introduces Clojure syntax and thinking, covering its core data structures, immutability, the thread-last macro and live data analysis in the REPL.

Dave Jones of EEVblog shows hand soldering of surface-mount parts, including drag soldering and tack-and-reflow of 0.5mm fine-pitch ICs, with solder paste and hot air.

Inigo Quilez live-codes the "Happy Jumping" animated scene in a Shadertoy GLSL shader over about six hours. He builds the raymarched character step by step, explaining the math and procedural techniques, with checkpoints linked for each stage.

A tutorial in the GAS Therapy series showing how to recreate the Teenage Engineering OP-1 and OP-1 Field with free software. It argues you do not need to buy expensive gear to make music.

Andrej Karpathy builds a GPT from scratch in code, following Attention Is All You Need and GPT-2/3, in about two hours using PyTorch. He connects it to ChatGPT and assumes familiarity with his earlier makemore videos.

Andrej Karpathy builds a bigram character-level language model from scratch, introducing torch.Tensor and the framework of training, sampling and loss evaluation. It is the first step toward a GPT-style Transformer in his makemore series.

Andreas Spiess explains the basic principles of LoRa and LoRaWAN, their pros and cons, link budget and bandwidth. He shows his own gateway and client sending a message to The Things Network.

Andreas Kling live-codes a prototype JavaScript JIT compiler for the LibJS engine used in SerenityOS and Ladybird. He builds a standalone bytecode VM, a simple interpreter, and then a simple JIT in about 80 minutes.

A motorcycle safety video on the SMIDSY (sorry mate, I didn't see you) accident, explaining the perception and optical illusion that makes drivers fail to see riders, and how riders can spot the signs and avoid it.

Ben Krasnow of Applied Science explains how electrophoretic e-paper displays work and how he modified the driver firmware and waveform lookup tables of a 4.2-inch panel to reach roughly 3Hz partial refresh. It covers the tweakable constants in the refresh process and touches on colored e-ink microcapsules.

The Thought Emporium shows how to receive clear images directly from GOES-15, 16 and 17 and Himawari 8 geostationary weather satellites with software-defined radio. It covers the extra effort needed to receive GOES data.

Russ Cox gives a 23-minute tour of the Acme text editor from Plan 9, showing its mouse-driven interface, executing commands from text, and its filesystem-based interface to other programs.

The first video in Photon of Scoopex's Amiga hardware programming series. It shows how to set up an assembler and write a minimal 68000 program that waits for a left mouse click.

A short video of stretching and hand exercises for preventing and easing tendinitis and carpal tunnel syndrome, from a percussion teacher. The exercises were shown to him by a doctor.

Day 1 of Casey Muratori's Handmade Hero, a live-coded game built from scratch in C on Windows. It reviews C on Windows, sets up a minimal build system and WinMain entry point, and shows a first MessageBox.

A walkthrough of installing Synapse, Riot and Jitsi from scratch on Debian to run your own Matrix communication service. The description warns it is now quite outdated and links to updated material.

Applied Science builds a replica Apollo DSKY using an electroluminescent driver circuit and screen-printed conductive ink, with source and PCB files published.

Ben Krasnow of Applied Science shows how to make small batches of specialty glass with minimal equipment, including designing and making photochromic glass. He covers ingredients, melting and the challenges involved.

A guided Wim Hof breathing session of three rounds at a slow pace, building from a 30 second to a 90 second breath hold. An on-screen bubble animation helps you keep the rhythm.

Big Clive gives a 38-minute beginner's guide to identifying common electronic components and what they do. He keeps the maths minimal and aims to fill gaps for people just starting out.
