I wanted to share with you the project I've been working on with the
BioBridge team from Noisebridge for the past two months.

It's called the BioBoard, and it's a suite of sensors; pH,
temperature, near-infrared and dissolved oxygen, with a logging
platform and a web-based graph data viewer.

We did this as part of the Great Global Hackerspace Competition which
ends today. You can see a short video about the project here:

 http://www.element14.com/community/blogs/bioboardblog/2011/05/04/happily-ever-after

We're still ironing out the last kinks in the home-built pH sensor and
dissolved oxygen sensor, but they should be good to go fairly soon.

Hope everything is well at BiologiGaragen!

Happy hacking.

This looks pretty cool.
A couple questions: how well do your DIY sensors survive whatever
sterilization techniques you're using?
Can these instruments be autoclaved?
I've often had problems with various cements not sticking well to the
plastic insulation coatings on wires. The lack of adhesion tends to
break the seal after a while, especially if the wires get flexed a
bit. Does your aquarium cement hold up well for that?

Thanks for posting.

All the noisebridge links on that page are linked to the same page,
pointing to information about the temperature probe - nothing links to
pH, oxygen, etc.

Thank you.

Maybe the author of the O probe article should put a caveat at the
beginning of the article stating that what follows resulted in a non-
functioning unit.
It's a bit of a drag to read the entire article only to see at the
very end that it doesn't work, followed by a "help me somebody."

lol, I hadn't even noticed - I kinda rolled my eyes when I saw it was
all sensors without automated processing - most temp sensors and light
sensors have outputs that work flawlessly with the Arduino analog
inputs or are trivial to just add a resistor array across multiple
pins to get the precision - though the O2 and ph sensors are kinda
cool.

[Rikke Rasmussen]

In all honesty, we don't have answers to all of those Qs yet. We finished the build yesterday, and are only now starting to discuss which sort of tests we want to subject them to - both for validation and calibration purposes, and for physical/chemical stress endurance. Will give it a shot, though:

The sensors handle ethanol sterilization very well. At least so far. We haven't tried autoclaving them, but PVC and acrylic generally doesn't hold up so well under high temp., so don't think they'd survive that. The aqaurium sealant is silicone-based, and thus very flexible, so am hoping it'll hold up - but like I said, we don't know for sure yet.

The sensors generally cost $5-10, depending on how much solder, wire, etc. you've got lying around, so you could build a couple and help us find out? =)

I think the silicone should work pretty well. I've seen high grade
sensors sealed in silicone before, and that's what i plan on using for
my temp sensors. Under heavy use and flexing i would imagine they
could break or wear, but since they are fairly cheap it's easy to make
more.

@Cory - DIY automated processing from scratch in 5 weeks on a $900 budget - including the necessary monitoring array?! Are you joking?

I forget most people haven't spent the majority of their waking life
programming.

[Jelmer Cnossen]

Rikke: Good job on the bioboard, it looks really nice. Is this going to be further developed or was it mostly for the competition? Maybe it is suitable to distribute/sell as some sort of kit?

CoryG: They present their cool DIYbio project which has nice data logging if you watch the video. Maybe you can think of a better response than being a negative jerk?

[Rikke Rasmussen]

@Jelmer: we'll definitely keep on developing! Primary target was never the competition, just happened to coincide with our plans to start doing 'proper' science in the kitchen at Noisebridge. Have also discussed the kit option, but no conclusions on this as of yet. 

Should any of you happen by the Bay Area Maker Faire in 2 weeks time, you should come by the Noisebridge table and see the monstrosity for yourselves =)

Seems like a DIY spin-coater is in order to get those films to be
consistent. Probably could make something out of a VCR head or CD-ROM
drive. That would be fun to work on if y'all are interested!

Wish I was out there for the Maker Faire, but I'll have to make it
over there once I get out there for the summer in June.

We certainly would! Should probably put you in touch with Sean, the (al)chemist who's been working on the optode.

Will you be out here for the DIY bio conference in June?

/Rikke

[Nathan McCorkle]

I'll be out there for the whole summer, from June 6th to August
12th... sooo I have to check the conference dates, but yeah I'd love
to be there!

[Nathan McCorkle]

Please forward this to the bioboard optode guy, but it seems that you
could have bought a different Ru complex, for example I quickly found
this one which is about 50X cheaper, and also demonstrated in oxygen
sensors:

yeah, the BioBoard Rockz!

have been talking to Rolf aswell, at my last visit to noisebridge.

we have been following a similar ultra-low cost approach for an input/output board to use in the arduino community. check the BabyGnusbuino:

http://wiki.sgmk-ssam.ch/index.php/Babygnusbuino

runs on an attiny85, that is compatible to the arduino IDE due to a special v-usb bootloader. no extra parts, or programmers needed. special midi version that just sends your sensor data as midi to your pc, is also woring.

total cost should be less than 2$.

and spin coaters are useful... made one from pc-fan and old harddisc drives

best,

That really has nothing to do with the dO sensor though! :)
