Hi everyone,

We (IO Rodeo) recently launched a DIY colorimeter kit on Kickstarter. The idea behind this project is to produce an affordable colorimeter which is completely open source - designs and software - and programmable for more advanced students/users. The ability for users to actually build their own colorimeter from a kit was important to us when we designed it. Unlike the usual out-of-the-box biology instrument (which can be somewhat of a mystery unless you like digging around manuals) with this approach users can see how the electronics work, how everything is connected, what the software is doing etc. and can ultimately hack it or modify it for projects or other tasks.  The colorimeter itself connects to an Arduino and we have put a bunch of additional resources on our website at www.iorodeo.com/colorimeter.

As you will see, it is a pretty simple, affordable instrument, but we think you can do alot with it, especially in teaching intro chem and biochem labs. We would be really grateful if you could you check it out and spread the word around the DIY Bio community - here is a link to the Kickstarter: http://www.kickstarter.com/projects/iorodeo-colorimeter/educational-colorimeter-kit.

Cheers and hope all is going well with your projects,

Jo

Looks pretty cool, I just signed up to back this one. Jo, how hard do
you think it would be to swap out the LEDs for a different wavelength?
Also, is the LED one of those 3-in-1 LEDs or is it 3 separate
components?

It looks like it is a single RGB LED, digikey part 475-2822-1-ND
