Author [Project] Turing Machine Mk2
Tombola

The new Turing Machine is finally finished. It is a random looping sequencer, with many improvements on the previous version:


    * Rotary loop length switch
    * Pulse out
    * Two boards, includes Backpack circuit to drive expanders (compatible with old Music Thing expanders)
    * Easier to build: a larger PCB in the same width, clock and noise circuits are more robust
    * Noise level trimmer & reduced voltage in noise circuit to make circuit more robust with different noise transistors
    * Compatible with existing Music Thing expanders


Kits will soon be available from Thonk

Design files are in Github (BOM etc on the way when I get to it)

And here's DivKid explaining the whole thing BRILLIANTLY:

w00t!! w00t!! w00t!! w00t!!

looks awesome, new panel design is cool as hell! nanners
Bamboombaps
Awesome been looking out for this.. Mabye ill get this one to lock hmmm.....

so i have all the parts for the ver1 lying around except for the pcbs. missed the last opportunity to buy them from thonk and now with the ver2 around, i'm wondering how much difference is there in terms of parts? i don't expect them to be identical hmmm.....

Not identical, but limited changes - I'd guess maybe 10% different.

The little trimmer (behind the hole between write & scale) is designed to make that easier.

huzzah i love front mounted recessed trimmers that are still accesible through the panel!

Any chance there will be black panels to match the old expanders?

edit:

I'll do a final run of the acrylic panels but I won't be making new acrylic designs for the new modules. But I will be releasing all the manufacturing files for them and details on getting them made. So it would be quite simple for someone to make new designs to match.

Any plans in the works to house this and all the expanders under one panel?

Considering it, but with 5 expanders and rising (including chaining multiple volts modules) it doesn't make quite as much sense anymore I don't think.

So you won't be clearing your acrylic stocks anymore?

Sorry I should be more specific, I am going to do another run first. But i'm not producing a design for the new module in the old styles.

this is just perfection, will get one with the pulse expander It's peanut butter jelly time!

Cool! w00t

Does this preclude the 9v regulator fix from the older version?
midirobot
so cool !!!

can t wait to try:)

Brilliant stuff. Btw if I replaced a resistor with a trimmer in my original one could I trim the locking problem away? If so any idea which one? Or is it all different now?

So, I understand locking to the left with the length selector 16 makes the loop length 32. Does it then mean the other length values on the selector will be doubled when locked to the left? hmmm.....

Magpie Modular makes it for the first version. I think that they will make it for this one too.

It has a completely new voltage reference for the DAC, should have more stable voltage outputs. The expanders all use the old 9v system.

Yes, so you can do 4, 6, 8, 10 etc

You could try replacing R31 with a 1m trimmer

Little OT: I'm going to build a mk.I, what's this locking issue everyone's talking about here? hmmm.....
