Making a simple variable capacitor

Posted on April 24, 2023 by robertwilkie

Clever build with 3D printed parts and some PCB boards. Good way to teach variable capacitance to folks. https://hackaday.com/2022/03/07/a-variable-capacitor-for-not-a-lot/

Convert your cheap CNC to a plotter

Posted on April 14, 2023 by robertwilkie

Pretty much adding a drawing attachment to a 3018 CNC (which I think runs around $200). Not a bad idea to multi purpose the CNC. https://www.instructables.com/CNC-3018-Cutting-Plotter-with-Workflow/

Make a portable wind power device

Posted on March 31, 2023 by robertwilkie

Nice build, not so sure I would use 3D printed material (sun and weather not kind to this stuff) but still a nice build for a simple wind power generator https://www.instructables.com/HOW-TO-MAKE-a-PORTABLE-WIND-TURBINE/

Make killing bugs a game

Posted on March 10, 2023 by robertwilkie

This one is a bit crazy, the author basically modified an electric bug swatter to keep things like a kill count. https://www.instructables.com/Ultimate-Mosquito-Swatter-Mod-for-Gamer-Add-Kill-C/

Cool CNC engraver using Solar

Posted on March 1, 2023 by robertwilkie

Nice build, the author has 2 issues, 1 it takes a long time to engrave, 2 once done you need to close off the lense so you don’t keep burning. Since lasers are some of the most expensive bit for … Continue reading →
