QR codes for humans

Pretty much everyone has a smart phone with a camera now, and QR codes seem to be here to stay, but there is a problem with human facing use in my opinion.

The problem I am talking about isn’t malicious use. The problem I am talking about is that barcodes are designed for computers, but today they are incorporated into use for humans.

That is a bit poorly worded, so let me give you an example instead.

While this may “work,” it is pretty clunky. Putting logos in the middle of the code and relying on error correction really grinds my gears too.

Let me restate the problem then, the problem is that people see the QR code, and it is a lot of distraction noise to them. So I propose that we hide the QR code from humans.

Android “game”

I made an android app called sleep solitaire in unity. It isn’t much, and has some bugs, but it works. Feel free to download it.
I thought about putting it on the play store, but it costs $25 to make a dev account and I don’t really think it is worth it for this.
If I decide I might do more, I might make a play account though.

Modular grid storage. PRE-POST

 

I wanted to make some grids to put on the drawers/shelves that hold tableware in order to let dust and such fall through. This project has gone through may iterations…

Some random samplings of revisions. Things like strength, tolerances, and print time can be difficult to simulate for FDM prints.

Robut

I wanted to make a simple robot chassis that could have things added to it as needed.
I decided to go with some pz22gr9120r gearmotors because they are cheap (~$3 each) and easy to find. The 1:84 gear ratio and 6-24V operating range means that they aren’t going to be going very fast on a 2s or 3s battery pack, but for just playing around I think that robustness is more important.

The body has a 20 mm grid for attaching components and takes about 12 hrs to print. The bottom takes another 3.
