    If the saline solution is mixed well enough, yes. If it's not because you didn't physically disturb it enough or you used cooler water, the salinity in one area is going to be different than another...

    Yep, or just additional noise and distortions in general. Laptops are particularly bad about current creating noise on the jacks when they are plugged into DC rather than running only on battery....

    Dampening and Analog vs Digital

    Yes, it would take care of any distortion in actual mirror position due to noise, or vibrations. However, what about the printing material itself? Just because you dampen the mirrors doesn't mean the...

    Most people can't really get access to this. Sure, if you really wanted to really badly you can get a 3D printed receiver and use it a grand total of like 100 times if you're really lucky, or print a...

    I think more likely what we're talking about is a short list of sound cards that do not fit the vast and overwhelming majority of sound cards that are in use today. Matching some widely used...

    Universal interfaces are intrinsically flawed.

    I agree with this. You might be able to literally make it universally compliant with existing sound cards, but the next day someone in china will make a sound card with a higher SNR than you expect...

    I know the process of research and development can take a lot of time on its own. Add to that documentation, public relations, and dealing with outside entities and you've got yourself a monstrous...

    Ugh... virtual reality. When we can connect telepathically and using something like the Matrix I'll be a believer.

    Yeah, it probably wont' be an issue but I like to build things so that it's not possible for them to be an issue. Kind of like how you suggested PWM instead of further complicating the AM signal with...

    Hah. Well I know what a Unix Timestamp is! I just didn't realize TS stood for timestamp there. I mistakenly viewed the automated notice as a topic or message left behind by a person. :) Makes sense...

    Drift

    I'm just saying it is something that should be given some attention as it's scaled down more. All I mean by relativistic is that the forces from viscosity is basically negligible beyond a certain...

    Yes, which should be a constant PWM per layer. The only time the PWM should change is when a layer will take more or less time than the previous layer. The only time the PWM will be off is when the...

    Is there any irc channel out there for peachy? I see #peachyprinter and #peachy on freenode, but they say: [15:58] -holmes.freenode.net:#peachy- *** Notice -- TS for #peachy changed from 1403639902...

    EDIT: I just realized that Rylan has already taken pretty much all of this into account save specifics of electrical and programmatic operation, so perhaps we should focus on that. :S

    Yes, and it really doesn't change the price much either. They should definitely be epoxy/polyurethane coated. Also, I did a bit of digging looking for some indication as to whether a cell phone...

    That looks really simple and could be very effective. However, I think you should modify it to work around the current modulation scheme the peachy uses for mirror positioning. This would need to use...

    Is 38 being chosen for price, availability and speed of manufacturing, or would you prefer something closer to 52? and what kind of wire? Looks like bare copper in the picture. I have some 34 I can...

    SNR across multiple devices and limitations of imaging for resin height determination

    @Compro01. Ah! I see. I wasn't aware of this. I don't know very much about peripherals of these kinds of handheld devices, but I guess it makes perfect sense with products like Square's card reader...

    Time constraints, volatility, and patents.

    I would assume that the reasons they have for not releasing the code yet has to do with their time being taken up by development and the code not being finalized yet. They are still changing the...
