half_built_pyramids

Poofy tshirt sleeves are the worst. Is there a name for how the sleeves are cut? When my arms are at my sides I want the hem of the sleeves to be touching my arms, not shooting out at 45 degrees. Same for any short sleeve type shirt.

Working on a joystick. Seems like any protocol I use to read from peripherals is going to be bottlenecked by having just one input. My microcontroller might have multiple ADCs, but there's just one processor stepping through them. Same for spi, or i2c, or uart. There's really only ever one sensor reporting back its data at a time.

I know this might not matter for measurement resolution. Especially if you're polling at like 115k serial or something, but...

That's 8 bits per axis, and three axis. Now that's at least 34 bits. To sample each axis we're down to only 4.5k samples per second. Plus whatever other cycles the controller has to handle... even if I spent half that time doing microcontrolle cycles at like 2k we're probably still well with the best star craft apms or whatever. I'd still like to find some way to really over engineer this thing.

I read a little about tdm, but that's out of my league and I don't know if you could even have 3 simultaneously signals that way

I'm thinking a microcontroller for each axis, and a usb port for each of them. So it appears like 3 different controllers to the computer. The user would just have to map the axis from the 3 controllers into 1 in their game software. I assume the steam remapping could do this.

Is it just going to get smashed back into one thread in the computer's usb hub anyway?

Any other suggestions?

Just doesn't live up to expectations. Entering an alias always feels like a double chore, even with the macro.

Picked up this trackball and it works great. This GitHub also got me started with Arduino code:

Among other resources and tech. I used this guy's mush client a thousand years ago also. Great website.

Planning on building a flight stick for a space sim. I understand some basics and I've messed around with an Arduino and a breadboard.

In the planning stages now. Should I measure the axis and rotations on the sim stick with hall effect sensors? Is there a more precise alternative?

I would also like to control the tension on the stick with brushless dc motors like done in this project https://youtu.be/ip641WmY4pA and I think the hall effect shouldn't get interference from the motors. Hopefully.
