Hello everyone, and welcome back for the final installment of the BioBoard blog! Today is the last day of the Great Global Hackerspace Challenge 2011, and thus our last chance to tell you about all the cool stuff we've been doing on this project over the last 6 weeks. In all fairness, those of you who've kept up with the blog already know most of this, but since this is our last post, please bear with us as we do a quick run-down of the project once again.   Our initial target with the Bio ...
Hey folks! Just a quick peep from yours truly here to give y'all a quick insight into the hectic last-minute tinkering of the BioBoard team. We're now 2 days, 23 hours and 38 minutes from the GGHC 2011 dead-line - that'll be Tuesday 3rd May at 00:00 hours - and officially in crunch mode. The project has shaped up really nicely in the last week - the two thermal sensors are finished, have been successfully wired up to Arduino boards, as has the NIR probe, and we've had live data transmission and ...
As promised, here's the second half of the BioBoard GGHC 2011 project:   At yesterday's meeting, our two chemists really got their act together to show off some truly awesome skills - Sean's long-awaited ruthenium catalyst for the dissolved oxygen sensor had finally arrived, and Otute brought in what initially appeared to be some rather odd Christmas decorations, but turned out to be one of the coolest hacks I've ever seen: home-made pH sensors from glass baubles! It turns out that the gla ...
Howdy, and welcome to another installation of the BioBoard project! While the guys wind down tonight's meeting in the background, I've gone straight to the box to tell you all about our latest progress, because I am really, really excited about this! Although yesterday was originally meant to be our final deadline for the sensor build, we've decided to extend that by another 10 days (until April 27th), leaving ourselves only a single week to make sure that all components communicate and do what ...
It's been quite a while since our last blog update - I shamefully admit to have neglected my duties as project correspondent somewhat this last week. Everyone (else) has day jobs, which means that most of us are working in our separate dens most of the time, and only really come together once a week, so I haven't been keeping up to date with the rest of the team quite as much as I should have. What's worse, though, is having brought my vidcam to the second meeting in a row, only to get so wrappe ...
Ho All!  I'm Charlie and I imagine that I am a materials scientist - designing and manufacturing such things as rare earth magnets and medical devices.  My task is to address some of the temperature measurement aspects of the BioBoard - we want something that is inexpensive, robust, sensitive enough for bio-systems in the appropriate range of interest (say -20 C to 150 C), and reasonably accurate.  We considered a bunch of different choices - thermocouples (TC), resistance tempera ...
Hi kids - Sean here. I'm the dude trying to make a dissolved O2 (DO) sensor from scratch! You may be asking yourself why you care about dissolved oxygen in the first place...the short version is that dissolved oxygen is an important factor to know when determining if a biologic system will live or die. Only a tiny bit of oxygen, and you wind up in a system that you readily see in ponds: most organisms survive based on photosynthesis alone (like algae). A lot of oxygen? You get a system like th ...
We are now one week into the Great Global Hackerspace Challenge, and the activity level on mailing lists, Google groups and blogs really spells out that everyone is gearing up for what will undoubtedly be a truly epic competition! So far, the communication between the hackerspaces has been pretty massive, and I'm starting to get my hopes up that - as well as all the inherent benefits of 30+ groups of talented, creative, determined people working on 30+ projects that will enhance education world- ...
As some of you readers may already know, Noisebridge (a hackerspace in San Francisco - http://www.noisebridge.net) is a big place, big enough that we initially had two different projects entered in the Great Global Hackerspace Challenge 2011, but as of today, we're down to just one. I just received an email from the mastermind behind the other project to the effect that they've chosen to withdraw from the challenge - no reason given, but I'm guessing that the problem is finding enough people to ...
Howdy, one n' all, and welcome to Noisebridge, a hackerspace in the Mission district of San Francisco, CA, and home of the Biobridge group (represented in this context by yours truly), one of the teams competing in the Great Global Hackerspace Challenge (GGHC). I'll introduce both myself and the rest of the team a little further down, but first a little bit about Noisebridge itself.   Noisebridge is my favourite place in the whole world for a gazillion reasons, but first and foremost among ...
