Re: [DIYbio] DIY nanodrop alternative?

I posted off list by accident. Here was my response to hugo's question:

So far so good. Still working on the integrated microcontroller PCB and
arduino shield alternative. I've been using my prototype for the last
few weeks making competent cells and such and it works quite well. The
only issue is that due to the arduino's crappy clock and edge detection
I lose some edges if you make a reading at the wrong time so I'm not
comfortable charging anything until I get this important issue fixed.
It does not hinder the performance, rather you may have to blank a few
times to get a 100% transmittance reading. I'd like to add a custom
circuit for edge detection so the only thing the arduino needs to do is
output to the LCD and down the USB as serial IO. Will start working on
that issue with more intensity now that I know someone is interested.
There are others on the list working on a similar device so they may
chime in too.

Don't go Kickstarter; they've already demonstrated a dislike of
Science. Go with any of the other crowdfunders or selfstarter.

I will be happy to snap one of these up; I still have no working spec
and could use one.
