The Technology Squared Tiles. Planned since the early days of 2020, this is a very large project with a very high price tag, planned to take a very long time to complete. Well, that mainly depends on how many tiles are being installed.

This project is planned to be printed on the SecSavr Suspense [gd0105].

The reason behind this project

In terms of practicality, this project scores low. However, in terms of personal morale (basically company morale but I'm the only one in the company), it's very high.

This is supposed to be a long term project that is sufficiently large and cool enough to prevent any other random projects from cropping up, as well as making sure I'm thinking of the future when I'm working through the projects of today. For my LED animaition projects, the basic idea of scale is:

  • [T] Installation location and material issues

    I'm thinking of going with a 2 wide by 7 high installation in a corner of my room.

    I'd like to be able to power all tiles with a single 3kW socket, and I think I should be able to get 14 to fit in that power envelope. the space in the corner will allow the installation to be more like a pillar and not something that has to be attached to the wall in some way.

    In other news, it doesn't look like the material situation is looking that good, so I'll have to factor in the price of standard rate filament. Maybe silver won't look so bad.

    This is the concept model of one of the tiles. The frame is 4040 alu extru and the motors are all Nema 14 except for the N23. The front tile is a 256x256mm LED matrix and the back is an array of COB leds for backlighting effects.

    One of the main positions I wanted was for the tile to be planar with the ground, so something like Fluidum wasn't going to work. I also want these tiles to be quiet as I intend to have them running in the background, so hobbyist servos were also not an option. I've already bought 200 Nema 14 motors. 

    3 Axis

    Originally, I only wanted to go with a 3 axis tile, but the concept turned out to be too large and likely too wobly to work (not like an arm configuration is any stiffer)

    Perhaps I could revisit this idea, as less motors means less motor drivers and less power consumption, meaning more tiles for a given power socket. It also makes animations faster to make. The 7x7 wall installation would theoretically take up more power than the 3kW from the socket, so I started looking into battery storage solutions so that there was a store of energy in times when the tiles took up more than what was available from the mains. I also wanted to cover the tile in a fabric like material so that it just looked like a nice looking wall when it wasn't doing anything.

    Reducers

    For the motors, I've opted for a harmonic drive that I currently haven't tested. It's currently a 17:1.

    It uses a TPU belt-like print for the gearing.

    Looking at results from other peoples designs, I'm thinking of going from a dual bearing to a triple bearing to increase the amount of teeth engaged. 

    The top bearing is a thrust bearing.
    There is also a double bearing version:
    This reducer is for axes that have the space for it, so that the overal arm is stiffer.

    This project was mainly inspired by all the Portal 2 videos Youtube was recommending me in Jan 2020, as well as this video from Apple, namely the background at 0:11:
