Hello HN, I find it easier to learn through practice and repetition so I made this little game to help me with resistor colour codes.
At the moment it picks a random E12 resistor value, but at some stage I'm hoping to have time to update it so that you can pick different series, tolerances, and number of bands.
Someone on reddit asked why it doesn't just get the player to type in the value of the resistor into a text box (like 1M, or 6.8k or 150R or whatever), and the reason is that I think it's much more useful to learn the colour translations directly since converting the numbers to a resistance value is trivial. Getting the numbers right first is more important.
The source is on Github, but since it's an entirely self-contained HTML file there's nothing much to see.
I've only tested this on the latest Chrome on macOS so YMMV with different browsers and platforms. If you have any issues you'd like to report please add them to the Github tracker or reply to this comment. Cheers :)

I still recall when I realized, as a kid, that the middle six are in rainbow order.
