That's not true at all and hasn't been for a long time. Maybe if you're mixing more than 8 tracks on a low-power CPU, but even a chromebook can do that sort of thing. Even my phone (several years old) can do that. Playing back stereo audio (which all that's required here) is something that can be done from a device that fits on your keyring. What you're arguing hasn't been true since the 90s. Certainly, it would be b…
I'm not talking about 'can you play back audio', I'm talking about 'can you play back audio with zero glitches'. This becomes a problem of scheduling precision, whether or not scheduling will 'stall' if a driver hangs while processing an IRQ, whether or not the graphics driver has a potential to hang due to a rendering operation, etc, etc. These are all a reality on modern desktops even if they're fairly rare (I don'…
I am a professional sound recordist for film and I also make electronic music; my office is a studio. I do not consider this a problem for this application.
Latency and glitching can become an issue when you're trying to record and monitor in real time while also operating plugins and multiple tracks. That's not the case here.
In passing, I'll tell you what is really a problem on current iterations of Windows: MIDI over USB. Audio is OK, MIDI is atrocious.

Line noise is a bit of an issue, but that's usually quite high frequency which means it can either be filtered or that the errors will be correspondingly small. Latency and glitches are not likely to be an issue at all, even the crappiest computer nowadays can handle multitrack audio and delays of a few milliseconds that would interfere with music performance are not going to have any impact here. Likewise sampling r…
Thanks for the points on how trivial it would be to handle line noise and playback glitches. Makes sense to me; I just don't know my hardware and analog circuits well enough to know how cheap it is to filter that stuff out.
No problem. Sorry if my other comment wasn't informative.

The Raspberry Pi only has 12 bits of audio output resolution and - at least historically - has had problems with latency-related audio glitches due to Pi-specific drivers spending too much time with interrupts disabled.

It's only a problem if you need very low latency. This system doesn't, so you can just set a massive interface buffer size. Scheduling is a complete non-issue if you have several seconds worth of output buffer.
When professional audio people talk about the difficulties of glitch-free playback, they're talking about running their CPU at near 100% utilisation with 64 or 128 samples of buffer. Playing back a clean and glitch-free audio stream is trivial and has been for years.

I really like what i've seen so far :)
But i do not understand why they are running a kickstarter and an indiegogo campaign at the same time for the same product with the same setup and rewards. Only the campaign duration is slightly different. Anyone got any ideas why this would make sense?
PS.: On indiegogo the early bird special is still available ...

#57I wonder how much error is introduced by the use of the headphone jack to drive the printer - you've gotta deal with line noise from the computer's sound card, mixing latency/glitches from the OS, and the device sampling rate, along with any noise introduced on the audio cable. Does a 3D printer like this not actually require high-precision data to work correctly?
I've seen sound cards with all kind of glitches such as outputting one of the channels with an inverted phase. I'd be also concerned with whatever audio filters the card may have. Sound cards are just not meant to control precision equipment like that.
Including a low cost USB adapter (even an audio one) that is tested and calibrated to work with the printer could prevent a lot of headaches in setting this up.

I wonder if the precision would matter a lots.
Lots of lag may cause problems:-\

#59This is great stuff. I have no idea what I'd use a 3d printer for, but this guy's awesome approach to engineering has me wanting to buy one just to reward his work.
Where I work (large university) the instructors and professors teaching engineering labs build pretty much all the setups for the experiments using 3D printers and off the shelf components. It allows them to iterate very fast on designs and can also change the experiments year after years, since they are not stuck with some expensive machine or piece of equipment. It really is an amazing technology.
I used one for a personal project I'm working on. I'm building a robot and had trouble finding wheels for it that fit my design, so I just made my own!! Got some silicon rubber strips from McMaster-Carr and now I have very fancy and functional wheels! Of course I am very fortunate to have access to a very good 3D printer, which is a few years out for most people.

Advertising in two similar, but not exactly the same markets at once?
Although, I feel like the indiegogo should have some sort of outreach to it as well. Like, "$25 gets you resin or a t-shirt and you (along with 5 other people) will sponsor a printer for a school" or something like that. Or perhaps focus on how the money from indiegogo will be used to make the software more accessible and easy to use for all people, not just those skilled in CAD.
EDIT: The indiegogo uses a fixed-funding model like kickstarter. I wasn't aware that projects could do that there.
