Insulate the bottom of your heat bed

Posted on May 22, 2023 by robertwilkie

You know I didn’t think of this before, but its a good idea. The heat bed on a 3D printer will “waste” heat from the bottom, so you waste energy. The author puts insulation on the bottom to help reduce that cost. Not a bad idea.

This was one of the earlier (last year) designs for turning a bottle into filament. Just got around to reading it now.

Making a coil winder

This case the author wanted to make electro magnetic coils, but I could see this used for other builds.

Posted on May 8, 2023 by robertwilkie

Well a ring with an RFID tag in it. There is an arduino that reads the tag and unlocks the door.

Nice portable windpower

Posted on May 5, 2023 by robertwilkie

Its a small portable windpower device that charges up a portable battery to use at any given point in time. Downside is the 3D printed parts could degrade overtime outside. Would be nice if there was a commercial (cheap) version of this. I like how it folds up for transport
