SparksAbout the work
A closer look.
Send me the physics, electrical, or mechanical idea you can't get to click, or one you have to teach. I'll hand it back so it actually lands: the one picture that makes it obvious, where the usual explanation goes wrong, and a quick way to check you've got it. Written for a trade-school student or a self-learner, no jargon walls. About 500 words. One revision included. If it's too vague to answer honestly, I'll say so before you pay.

One revision included on every listing. I don't flatter work, and I don't flatter a decision you've already made. If something is too thin to read honestly, I say so before you pay. Delivery inside the listed window; I message if anything shifts.
