Playing a mp3 from an esp32 using MicroPython mp3 player module: abra-electronics.com/robotics-emb...

As much as I hate on vibe coding, there's one place I have found AI somewhat useful... For turning a rough sketch into a realistic graphic Here's an example of an idea I had for a mini AAA-battery powered multimeter:

Rough idea: A wireless multimeter over UDP Code: gist.github.com/joshnuss/cb8...

Detecting motion with an infrared beam Using MicroPython and an ESP32 Link to sensor: abra-electronics.com/sensors/sens...

Wired up an irrigation system for a flower pot. Used a fish tank pump and some tubes to create a sprinkler ring along the rim.

I wanted to understand how a minimal ESP32 board works So I created 3 custom breakout boards with KiCad:

Soldered it up.. might add a LiPo battery, so it's truly wireless

Does AI improve productivity or damage cognitive function? MIT study: www.bbc.com/news/article...

Built a 3.3V -> 5V level shifter using an OpAmp Cause I want to run a 5V servo from a 3.3V microcontroller

Figured out how to chase away Telegram spammers 👨‍🍳 Just reply with: "Response error -47: Insufficient OpenAI credits, try again later."

Built an HTTP based temperature sensor using ESP32 & DHT11: Full code: github.com/joshnuss/esp...

TIL: Running an SSH command from Node.js:

TypeScript template literal types worked well for this:

Before integrating with another system, it's a good idea to make a list of all API calls needed and test each one out. Only after that, is it safe to write production quality code.

TIL: Using OpenTofu to setup Hetzner resources: # to view expected changes > tofu plan # to deploy changes > tofu apply

Built a "sidecar" process for monitoring Node.js. It tracks all incoming HTTP requests, any console.log's and all exceptions thrown. It stores them all in a ClickHouse DB.

Nice that you can run Lua code in Nginx:

Todays experiment: Can I run a SvleteKit app with Postgres for $5/mo? The answer is YES.

Clear writing is made by editing. Clear code is made by refactoring.

I hope their website is using Bun.js 🙏

Messed around with Rapier2D yesterday, it's a pretty cool library.

Cool 2D game by @kempf.dev using Svelte and Rapier2D physics engine Game: subak.kempf.dev Code: github.com/takempf/suba...

I can’t wait for them build this in the future

Every few years I re-read Valve Corporations's New Employee Manual. Kinda wonder why aren't more companies operating like this PDF: cdn.fastly.steamstatic.com/apps/valve/V...

Built a step-based UI using CSS `counter-increment`: Code: svelte.dev/playground/b...

Built a context menu using pure CSS ✨ Just a popover with anchor positioning. REPL: svelte.dev/playground/6...

Planning to migrate off Podia.. So I built a Video LMS with SvelteKit Built on: - Cloudflare Streaming & CDN - Better Auth - Stripe Elements - Video.js Player - Content Collections (courses are markdown)

In 2012, I designed a watch that turns on when you lift your arm. Found it in the back of a closet, and it's still working :) Code & schematics: github.com/joshnuss/acc...

Used a Svelte attachment to style <a> when active (ie href matches window.location)

Built a video player that recovers last position using IndexedDb. Code: github.com/joshnuss/sk-...

I built this video using Svelte and the excellent Animotion.js library. All the slides (browser, terminal, and text editor) are Svelte components.

Built some window widgets for an upcoming video. Code: svelte.dev/playground/7...

Built a simple animated theme switcher with Svelte Code: svelte.dev/playground/a...

New Video: Build custom Neovim workflows ✨ youtu.be/F6glb6L7A_U With some SvelteKit examples: - Creating routes - Loading a snippet when file created - Switching between related files

Question: Do you prefer coding videos with graphics and slides? Or just someone typing in their editor?

Built some default templates for Svelte in Neovim ✨

At the local electronics store today, they said the open hardware project "OpenBuilds" has shut down due to Trump tariffs: builds.openbuilds.com/threads/open... Bummer, cause it was such a cool project.

Shortcut for creating a route in SvelteKit with neovim: 1. Type comma+c 2. Enter New Route, ie `about/team` 3. src/about/team/+page.svelte is created

New video: Neovim snippets from scratch www.youtube.com/watch?v=v4Vh...

Read "The Artists Way" in January and started writing 3 pages daily. Just did the math, and I've written over 600 pages since 🤯

TIL: An easy way to simulate hardware in Spline, is by importing CAD models from McMaster Carr

Built an nvim plugin to alternate between SvelteKit files. - Alternate between +page.svelte, +page.ts, +page.server.ts - Alternate between +layout.svelte, +layout.ts, +layout.server.ts With one hot key (I use comma + period)
