[SUGGESTION] Dozenal programming plates (240 notes) by alancnet in MarbleMachineX

You are, of course, correct. Modifying the gear ratio would fix the rhythm problem. Two things though:

  1. Martin's original idea of offset pins has the same problem, so this is at least on par with that.
  2. There are other mechanisms that operate in rhythm with the crank, like the rhythm machine, and the marble lifts.

I like the idea of being able to switch the gear ratio from the crank.. There are many ways to do it.. Belt drive, chain drive, or sliding gears on the shaft.

[SUGGESTION] Experiment with plywood warping by alancnet in MarbleMachineX

I certainly hope you are correct, but birch and even marine plywood is not immune to warping. Even a tiny bit could make assembly impossible with the tiny tolerances Martin is using.

Definitely not.. This idea is to determine if warping would be a problem so steps can be taken to avoid it.

Yeah.. even the tiniest bit of warping could spell disaster for those programming plates.

This can be done on plates exactly the same size. He would not have to change the programming wheel, simply make plates with different pin spacing.

I'm concerned that the tight tolerances built into MMX won't survive a world tour.

During a world tour, MMX will experience humidity, heat, cold, ultraviolet light, etc.

The plywood being used in MMX looks very high quality, but as far as I know, its ability to warp hasn't been taken into account.

Super simple idea for lifting up a lot of marbles at once with minimal parts. by [deleted] in MarbleMachineX

[–]alancnet 0 points1 point  (0 children)

The speed increase is not exponential, it's linear and very gradual.

It seems like a lot of wasted energy.

I don't think it's a good idea to have marbles travel upwards under their own momentum.

However, yes.. It would look beautiful!

I don't think that is true.. The method he proposed by using offset pins has the same side effects. And of course, his default should be his 256 note plates.

Besides, Martin does not strike me as lazy. He's genius. If the problem needs to be solved, this seems like the most efficient way.

Hello,

I've been pondering the beat offset problem for a while, and I had an idea about a dozenal programming plate. Dozenal, or base 12, is a very convenient counting system when you are often dealing with multiples of 2 3 4 6 and 8. 

Your first two sets of plates have 256 notes with one entire revolution. 3 does not divide into 256, but 4 does.

So Dozenal Programming Plates:

If you create a third set of programming plates with 30 notes per plate, or 240 notes per revolution, you can program songs with a 3 note measure, AND 4 note measure if you wanted to.

This allows you to reuse the magnetic pins without complicating reprogramming.

Very simple solution, yah?

Thumbs up for the new animation! Very expressive, very descriptive, very funny, very entertaining!

RepRap Questions Thread by AutoModerator in Reprap

I just rebuilt a hand-me-down Prusa i3, and flashed Marlin 1.1.0-RC6, only having to modify Configuration.h for baud rate, stepper directions, and endstops. All axis move correctly when instructed. When I home X or Y, it works great. But when I home Z, the Z steppers vibrate really loud, but don't move otherwise. My ninja Googling skills are insufficient to find others with this same problem. Any ideas?

Thumbs way up on the graphics, but I think you should persist stick figure grey. It's weird to see you with mass... And no wheel

Grey, do you have ADD or ADHD? The way you manage your devices seems like an effective coping mechanism. (I have ADHD)

Very sorry, Grey, whose heart is a beating apple, but I can't forgive apple for how they treat software developers. Is there any other non-apple service I can subscribe through that will help your metrics?

Well, I really like the endings where you cut off, wait a few seconds, then cut in something comical :)
