Actually, I did miss that. Nice touch...In case you missed it, there's an optical interrupter for the beam scale.
First:It's held together with rubber bands.
What makes it more interesting is that I get to write the software that controls it. In case you missed it, there's an optical interrupter for the beam scale.
Next step is to automate a powder measure to do the bulk initial powder throw. I might add a second optical sensor and have it do multiple speeds.
