lab tour

A 100-minute tutorial from Phil's Lab on designing an STM32-based 'black pill' PCB in KiCad 6. It covers schematic capture, two-layer layout and routing, USB, and sending the board for manufacture and assembly.

The first of a short series by Welch Labs on building a complete neural network in Python. It introduces the data and the architecture of a simple network before later parts cover forward propagation, gradient descent, and backpropagation.

A roughly three-hour screen recording of designing a barebones STM32F4 board in KiCad, covering schematic, four-layer layout and routing, USB and a buck converter. It ends with ordering manufacture and assembly through JLCPCB.

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.

Markus Triska tours Prolog's most distinctive features, including its use as a database and query language, rule processing, constraint solving and compile-time rewriting. It also covers concise meta-interpreters.

A step-by-step tutorial on making a Harry Potter by Balenciaga style AI video, using tools such as ChatGPT, Midjourney and Eleven Labs for script, images and voices.

The Thought Emporium shows how easily bacteria can be genetically modified to produce fluorescent proteins and even bioluminesce, with techniques doable at home. It links to companion videos on incubators, DNA extraction and gels.

Jeremy Howard's 90-minute practical tour of language models. It covers how they work, GPT-4's capabilities and limits, using the OpenAI API, code writing, data analysis and fine-tuning.

A short screencast tour of JSPM, SystemJS and ES6 features, building a small app with the then-new JavaScript module and package tooling. It shows how JSPM works as a package manager, bundler and loader.

Harry Schwartz gives a roughly hour-long tour of Emacs Org mode as an outliner, task manager, markup language and agenda tool. He demonstrates how he uses it for documents, presentations and todo lists.

Dave Jones of EEVblog and Richard Stephenson tour the 70m DSS43 dish at the Canberra Deep Space Communication Complex and explain how NASA talks to Voyager 2. It covers the transmitters, receivers and tracking involved.

Marco Baringer's tutorial video on SLIME, the Emacs mode for developing Common Lisp. It demonstrates the interactive workflow of working against a live Lisp image.

Dodoid gives an in-depth look at an SGI Onyx RealityEngine2, a $250,000 graphics supercomputer from 1993, covering its history, a physical overview, a teardown and some demos and games.

Ben Krasnow of Applied Science shows how to make and test YBCO high-temperature superconductor with a kiln and eBay chemicals. He demonstrates flux pinning and shows a close-up of the crystal structure.

A 2018 vlog showing how to use the windshield wipers on a Tesla Model 3, including auto mode, manual settings and voice commands. It is labeled outdated.

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.
