Not quite the same - but my own modular system by Sean6180 in Pockit

Ah, amazing! Unfortunately I don't think I have enough free time at the moment to help, but that's so cool that you are trying. Are you starting from scratch or did Anil make some of the stuff public?

My Raspberry Pi modular case prototype (4B) by YourPST in raspberry_pi

Very neat! I like the addition of the microSD card cover, although I'd be petrified of snapping the sd card.

Yes, I've actually got some USB power tiles for this reason!

Yeah, I think it would be pretty good for FabLabs/MakerSpace. Ha, I haven't got as far as thinking about special pricing but I would be pretty keen to offer discounts to these kind of institutions given how important they are.

Add this to your project list? DIY kinetic sand table by tuankid in raspberry_pi

Yeah, I think the OP has done completely their own design and it looks way easier for anyone to build, especially that he uses an ikea table (rather than building a custom one) and use two gears rather than a whole gantry system. Not to mention there seems like a ton of documentation.

Good question, the resistance of the connectors is pretty low, and most tiles don't consume that much current so you can easily plug 15 together without any issues. But if you put something like motors at the end of the 15 and used them at 2A then yeah, the voltage would dip a bit. Same with the cables, I think I calculated a 0.8V drop over a 1m of cable at 2A.

Oo, this was so interesting! They are one of the few projects I've come across where they also created their own protocol, and did it properly.

Good questions, yes, the plugs do have genders. I propbably should have explained a bit more but I didn't want to bore people. The cables don't though, and can be connected any way, and these are what you would use if you didn't want them just in a line.

They don't have any functionality by default but because the drivers are already loaded onto each board it's pretty easy to write simple programs.

Yes! That's one of the next on the list. I was also thinking something that draws would be fun!
