I like the error margin on resistors. Feels like any number without one is kind of incomplete!

Nice job! You may want to add a manifest so it’s easily added as an app on mobile (add to Home Screen)

This is a situation where rote memorization will make your life easier.

When I was about twelve and starting to experiment with electronics, a friend's older brother told me the resistor color code mnemonic which he learned in the US Navy.

It's absurdly terrible. Racist and sexist, not to mention grossly inappropriate for a preteen.

So of course I remembered it instantly, and permanently. I've spoken it aloud maybe twice in my life (among trusted friends and with a longer version of the above disclaimer!), but it rings in my head every single time I even glance at the colored bands on a resistor.

There are…a lot of these: https://en.wikipedia.org/wiki/List_of_electronic_color_code_...

If you do a lot of this stuff, definitely. But pro level work is mostly SMD, and a lot of hobbyists mostly do digital work with modules , there's usually few enough discrete parts that one can just use the multimeter.

If you're into the super cool discrete analog stuff than learning it for real makes sense though!

I love this! It looks simple and nice for embedding, instantly obvious how to use it.

I love the rendering of the metallic colors as real gradients!

The one thing I'd change is maybe slightly less blur radius on the text shadows, just for a little bit cleaner look.
