Builds worth a weekend

Issue 01 // October 2026A newsletter for makers
Extra Screws
Builds, hacks and the people making them.
A free newsletter for anyone with a project on the bench: boards, bots, printers and odd parts. Open projects worth a weekend, one shop skill, one datasheet in plain English.
00What it is
A bin of useful parts, every other Sunday
Each issue rounds up a few open projects worth a weekend. We link the original, credit the maker and note the license, so you know what you can borrow. When a project publishes a number worth knowing, we pass it on with the source.
- Credit firstEvery project gets its maker, its license and a link to the original.
- Numbers with sourcesIf we quote a figure, we say where it came from.
- Honest statusWhen a maker says something’s broken, so do we.
