Where to buy a Axoloti Core / Out of stock

#123

Not much to add beyond I would absolutely be interested in snagging a bunch of micro boards.

#124

I'd definitely buy at least one of any Axoloti clone, and especially like the idea of upgrading the MCU at some point.

#125

I have always imagined a version where as much as possible is broken out to IO.
The only item that could stay is the micro USB port.
Everything else can be broken out to basic IO .. power jack, USB host, audio inputs and outputs, S1 and S2, midi etc..

I think that the teensy3.6 nearly matches your description (but it does not have 8MB RAM).

I don't know if someone achieved to make the axoloti software run on a teensy.

that would be a fun thing to make axoloti run on the teensy!!

Hi,

At the moment, i am not playing much with my axolotis.

Because of professional circumstances and opportunities, i am in "student mode" and re-learning VHDL, FPGAs, FSMD and pipeline optimizations.
(that's why i did not added or updated axoloti objects last months).

Maybe a Zynq based board could be the future. This chip contains a ARM A9 processor and some FPGA "fabric" for custom circuits around the processor (multiple I2S interfaces, dedicated signal coprocessors...).

Fun and reassuring !

Teensy-size would be appealing, but maintaining 100% software/firmware compatibility is important. So, rearranging the existing parts, and omitting unwanted connectors, is the only practical way to go.

#131

i agree @tele_player. a super stripped down or amped up version is a great idea for the future but for now i think it only makes sense to put all effort behind making the current board (or 100% compatible) available asap. for serious new developement or alterations i think we all can wait a couple more weeks or months to see if the mastermind reveals some more plans that alternate board versions could work along with.

not saying people shouldn't try to get axoloti on the teensy now, but making a basic working compatible board available is kind of urgent.

#132

Not fond of the 3.5mm jacks, though i understand size matters.

#133

Is there something like a waiting list where you sign in to order the board? or you simply have to check the website once in a while?

#134

Would be hyped for the miniaxoloti too!

Although and axoloti ultra with more ram would be bomb to...

#135

I was just wondering, maybe this has already been covered, why not a board without soldered connectors? This would give more flexibility to box deign...

#136

I don't think there is any hidden waiting list.
I scan the website once in a while too.

It's been only 2 months since the core is "out of stock"... so wait and see.

#137

As I plan to make wind instrument, a mini version or a version without soldered connectors would be really great !

#138

+11111 I'd actually grab a number of miniaxoloti

@weasel79 and I are working on a mini axo core concept based on a prototype layout I did a while ago. He's on holiday at the moment, and I'm a bit busy with another project but when we left off we were discussing doing an initial run.

I'd like your feedback on part of the idea: I'm thinking of doing a "base" mini module with minimal IO, think of Raspberry Pi Zero scale with the addition maybe a couple of 3.5mm jacks. I then want to do IO modules that can stack on top, so full size DIN and 1/4" jacks etc could be easily added. Another stacked module idea would be one with a bunch of CV IO possibly based on the MAX chip that @weasel79 has done some experiments with.

The question is exactly how much should be cut from the base module and move to expansion modules. I think the base module should be actually usable without soldering, so maybe Micro USB power/data and host like the Pi Zero, SD card and 3.5mm in and out. Should the headphone jack stay on the base or can it be cut? Another issue: I'd like the base module to be purely surface mount components, again visualize the scale of the Pi Zero for comparison.

#140

definitely leave the headphone in, priceless for on the road patching...

#141

My original mini concept had three 3.5mm jacks: in, out and hphone. That feels a little busy. Maybe there's a way to be more efficient somehow. Or maybe that's kind of the lower limit. We'd just move the 1/4th jacks and DIN up to an optional HAT. It seems likes people are sort of divided on 3.5mm jacks though. Thoughts?

#142

me personally i would be happy with just the hp out. if you want to enclose the thing you either will buy the 1/4 expansion board or solder on your own connectors.

or thinking a bit further, leave the hp out, if the normal out is 3.5mm it should work with headphones anyhow, not perfect (volume) but it will work for prototyping
