Hagiwo Quantizer: how does it work, a bit of background

The Quantizer made by Hagiwo is a Arduino based quantizer. Hagiwo published all files and schematics. The code is readable and not packed into a hex files. I have put my own twist on the design by replacing the DAC.

The original post and design by Hagiwo can be found here:

So lets take a look on how it’s build and how it works.

Dotty: Buttons orientation (thanks Beta Testers)

I was in the wrong impression the orientation of the Dotty buttons didn’t really matter. I did place them all in the same orientation, didn’t mix it up but didn’t check also. Later found out I was lucky on most of the Dotty’s I build.

The buttons are read by a 4051 chips 8 buttons at a time I call them rows. All four rows worked most of the time. But one build had a problem with row three. When installed in one way the buttons Dotty stop recording steps. I rotated the buttons and Dotty worked again.

Thought it was strange never had it before on the previous versions, put it aside as a glitch to sort out. Then a beta tester reported the same. Now I had to dive into this problem and fix it.

Organizing Shop and Added v0.041 Nanogris

Today I started organizing the shop a bit more. Still not done, lots of work. The products have options to choose from now. Would like too add photo switching also but that would be a little bit more work.

The New Nanogris version is also added to the shop. I’m out of Quantizers but no worries these are ordered and underway.

NanoGris: A New name for NanoGrids

there are times you do things with the best intentions and still make a mistake. The NanoGrids module is originally by Mutable Instruments. The schematics are released under cc-by-sa-3.0 license on github. This makes these files open to the public to use.

Mutable Instruments is very kind to do so and ask for little in return. Naming your clone module is one of those little things.

from GitHub: We do not recommend you to keep the original name of the Mutable Instruments module for your derivative works.

I did not honor that request fully. I did not read it when building NanoGrids. It’s based of there Grids module. So I hope to make my mistake right again. I renamed the module to NanoGris
