Show HN: I made a resistor calculator with TS+React
- quickthrower2 3y agoI like the error margin on resistors. Feels like any number without one is kind of incomplete!
- jfdi 3y agoNice job! You may want to add a manifest so it’s easily added as an app on mobile (add to Home Screen)
- demondemidi 3y agoThis is a situation where rote memorization will make your life easier.
- quesera 3y agoWhen 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.
- jer0me 3y agoThere are…a lot of these: https://en.wikipedia.org/wiki/List_of_electronic_color_code_mnemonics#Offensive/outdated https://en.wikipedia.org/wiki/List_of_electronic_color_code_...
- quesera 3y agoI love that someone collected these. The one I learned (I guess I have to call it "mine") is an amalgamation of a couple of those. It's the "Violet gives willingly" version, with extra offensiveness to resolve 0 from 1.
- tzs 3y agoI believe I learned the same one as you, probably when I was around 12. I have no idea where I got it from. That would have been in the early '70s, and I was mostly learning from books from Radio Shack and the public library and from Popular Electronics magazine.
- eternityforest 3y agoIf 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!
- eternityforest 3y agoI 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.
