Missing cad/svg/whatever for laser cut out of parts

Great if you could add the definition file for the parts you printed to mate the blast gate with its RC motor. so those of us without printers, can just send off to our fav laser cutter service.

Love this overall. Got a few spin off ideas

Use a Low Pass Filter

Great video Bob. I have experience as a SW engineer, and I just wanted to give you a quick tip, if you're interested.

Instead of reading each value for 1 second, and averaging the results, you can use an "alpha beta filter". It's much simpler than it sounds.

double alpha = 0.1;
double beta = 1.0 - alpha;
filtered_value[which] = filtered_value[which] * beta + analogRead(PIN) * alpha;

If the alpha is 0.0, it won't ever change, and if it's 1.0, then it will take the reading immediately. If it's 0.5, then each reading is 1/2 of the current result. It sort of depends on the frequency you can read, but you can try something like 0.01 and see how it works. If it's too groggy, make it bigger, if it's too flakey, make it smaller. If you do that for each sensor during your loop, you won't have to stop reading the others while it's filtering.

I can make a PR if it's not making sense (I speak C better than English, so it's my fault if it doesn't make sense).
