A Quick Note About Covid 19

I’m committed to continuing to produce quality projects that hopefully both entertain and inform. While this pandemic is ongoing I’ll be skewing more towards simpler projects that you can make with things from around the home though there will still be plenty of more challenging stuff to do!

If you would like to become a member of the site for free access to all the downloads there is more information here. Don’t forget the discount code below! If you would rather follow me on Patreon the link is here. I post most days on Twitter and Instagram, follow me there to keep up to date.

If you do make any of my projects while you are self-isolating I’d love to see pictures and share them on the site!

Finally, if you are a member of the site already or a follower on social media, thank you so much, this is how I keep the site running, I literally couldn’t do it without you!

Stay safe everybody!

Cartesian Diver

Squeeze the bottle containing the Cartesian Diver and it sinks, release it and it floats again. Control the force and you can make the diver hang mysteriously in the middle of the bottle!

The download for this project includes fully illustrated instructions and an introduction to the science of the Cartesian Diver. Members can download the file by adding it to the cart for free. Thanks for signing up!

Circling Swifts

The homopolar electric motor is the simplest of all electric motors. Just a battery, a magnet and a wire.

In this model the homopolar motor is made from a battery, a neodymium magnet and a length of thin wire. Download the instructions for construction and make your own circling swifts!

Members can download the instruction file for free, thanks for signing up!
