<sync> they are using liquid phase epitaxy basically
<sync> you dissolve quartz and then use a seed crystal to grow the crystals
<SpeedEvil> Neat that it's getting so (relatively) cheap
<Noxz> the few sources of stacjed piezos I have found thus far are hundreds of USD, for minimal movement, so something is either not priced right, or they are actually about that much
<Noxz> I think I was kinda looking into how easy it may be to make piezo valves
<Noxz> but $100-200 on ebay isnt bad

<Noxz> hrm, a pound of barium titanate is $25 usd
<Noxz> decent starting point for prelim experiments I suppose
<Noxz> thats 0.5-3 microns
<nmz787> I was imagining two planes of piezo beamformers, such that you could create droplets with high-freq impulses, and if you had some of these planes opposing each other could you basically send droplets around from one plane to another
<nmz787> to do automated microchemistry
<Noxz> is there a 'standard' piezo that is used within ICs?
<Noxz> I know they dont use quartz anymore, right?
<Noxz> that's just external reference stuff for simple microcontrollers
<Noxz> I think the Branson ultrasonic homogenizers I have are some kind of barium based
<Noxz> I recall reading something about it in hte manual, nothing is really available online, but I did come across a patent from branson.. I thnk
<Noxz> that states barium titante
<Noxz> I have like 3 probes, two micro points and one that is about 1cm
<Noxz> I should just crack one open
<Noxz> oh, look, it lists two patent numbers on the probe
<sync> Noxz: ICs do not use any crystal internally
<Noxz> no?
<Noxz> set, clock speed is...?
<Noxz> so*
<Noxz> sorry, I'm here just to make tiny watch gears ;)

<nmz787> that link fails for me with "400. That’s an error. Your client has issued a malformed or illegal request. That’s all we know."
<nmz787> :(
<nmz787> oh, weird, it works in incognito mode
<nmz787> there is also some weird glitch I've been having with google maps
<nmz787> it also is better incognito
<mrdata-> no kidding?
<Noxz> heh, try logging out and abck in?
<Noxz> I sometimes have to restart all of chrome to make shit work again
<sync> Noxz: they use laser trimmed RC circuits
<Noxz> hrm, that simpel eh
<SpeedEvil> s first attempt at making the snowman consisted of just drawing arms and face of the silica spheres. This time aroundvhe used an ion beam instrument to carve a mouth and eyes and deposited platinum yo create the arms and nose
