Cool segmented “nanoleaf” like build

This is a neat build, basically its like a nanoleaf, but the “leaf” part is more like the segment you would use in a digital display, so you can combine those to make digits, or other shapes. https://www.hackster.io/news/these-nanoleaf-inspired-modular-lights-can-team-up-to-create-a-wall-mounted-four-digit-display-7a985c77ce68

Big 7 segment display

Need to make your own scoreboard, this is a nice build to start from, the large display uses an arduino to control it and the 2 digit display the author made was for timing swim trials. https://hackaday.com/2022/07/27/you-can-build-a-giant-7-segment-display-of-your-very-own/

Nice jig to prep large reams of paper for a binder

https://www.instructables.com/Paper-Hole-Drill/ Nice jig to use to convert ALOT of paper to go into a 3 ring binder. Most 3 ring binders have the same spacing so this should work with all of them. 10 years ago I would have thought … Continue reading

Neat build to generate electricity

https://content.instructables.com/ORIG/F3I/DLBR/L471K3FC/F3IDLBRL471K3FC.jpg?auto=webp&frame=1&width=320&md=ebb7014e9e5ebedade0ef4db007791ef Nice idea on how to build a simple device that uses gravity to convert things to electricity (of course you have to lift up the weight first). Could be a nice school poject. https://www.instructables.com/INSERT-NAME/

3D printing forms for making custom paper shapes

Basically the author takes old paper, converts it back to pulp, and then puts it into a form he 3D printed out to shape the paper. Nice idea to make custom containers.
