I came across the concept of zero pairs during some teacher training and thought it would make for a good Raspberry Pi and servo project. It can be used in class using a web based interface. Though I’ll probably end up setting it up as a Binary Clock - I’m a CS teacher
A quick demo of my zero pairs machine which uses Raspberry Pi and an Adafruit Servo Hat to rotate spheres to represent addition and subtraction of negative and positive numbers. See description for links to the the main video and to the irritating AI generated background music!!
This is brilliant! What a great way to learn mathematical thinking, especially the method of adding zero (pairs)! It's quite often used in simplifications and proofs. I wish i had been introduced to it in such a visual way 👍🏻👍🏻
I'm planing to use 16 servos and black rotating balls to create a visual demonstration of a maths concept. First, this project is an experiment in controlling multiple servos with the Adafruit Servo Bonnet and a Raspberry Pi Zero.

i’ve seen one video and i can already tell you have inspired countless amounts of your students. i’m inspired and i’m nearly 30 lol such a cool project and video
No, predictably the whole thing only lasted a few days. A straight projection worked the best. I don’t think you could get the full curved effect on a budget. I keep thinking about it though.
Fleet Farms all have orange planetarium domes on them. This looks easier than my globe wedge pressboard method. Though mine turned out to be completely smooth inside.
Wow, I don't usually do follow-backs, but we clearly have overlapping interests. I hadn't thought about making a very large cardboard rotegrity ball before, but now I think I'll have to consider it.
Ha! When I saw your channel I wondered why you didn’t have a million subscribers then I realised that maybe not everyone is obsessed as me! I found you on Reddit, then your YT and Etsy followed. I’ll be giving you rotegrity ball a go as soon as time allows! Look forward to seeing your channel grow, and I’ll certainly be watching with interest if you do any explainer videos. On the off chance others are curious, check out their shop here: www.etsy.com/uk/shop/OrigamiMarieArt
they'll be talking about this with your grandchildren as a grand adventure ! Nice work. I've actually thought of doing with with the ribs INSIDE and using it as a form to blow on a permanent fibreglass layer - I guess someone could add rebar over it and even use blown gunite and then paint it after it's cured.
Thank you! I didn’t except the dome to last too long but was quite surprised by how quickly it took on moisture and collapsed - we maybe had 3 or 4 days out of it. It was the morning dew that ended it despite it being warm otherwise. Good luck with your version- it sounds intriguing!
I really like how you do things. It feels like we can talk all day and night, or even for a month. Question though, is it possible to add a diffuser for the light to give it a uniform spread? that way it will only glow as one source of light, then the shadow patterns won't be overlayed?
Very, very cute. Informative and funny. I’d like to make this. The hardest part for me would be the paper folding. I’d like to wake up to this lamp. Thanks for sharing.
That’s beautiful, bro…a 3rd frequency icosahedron? 🤔 truncated it & added the vertical wall…very smart. It gives you some flat upright surfaces to hang pictures & stuff! And a pair of wings on top…that’s what I call bang for the buck. ✊☕️🎩🎩🎩
There has been tons of progress made toward easy to use LED animation. I still remember my first LED strip and how clunky that experience was. Tree looks great! Happy Holidays!
First of All: very Nice Project ! About this water problem: Applying Ship (Yacht) Varnish on the cardboard before assembly… also putting the bolts on the inside would turn the outside into a more smooth plane because now you have those upstanding sides creating a collection effect for water. Application of silicone in between the triangles, already mentioned by Tony Hardy, would seal the whole from further water penetration. Ofcourse you would have to apply an extra projection layer on the inside but I think it can be done. I also think if a person wants to create a larger structure with this cardboard material it will be more easy and safer to secure the bolts on the inside since you cannot climb on the outside or reach too high… anyway, I think it’s a very nice approach of a practical geodesic dome creation. Well done.
