A small box that could be cut from laser cutter parts, and assembled with simple components (screws bolts etc). Along with some slighly more complicated motors and electronics. Moving mechanical components could either be from laser cutter or from Makerbot (or RepRap). | A small box that could be cut from laser cutter parts (probably MDF), and assembled with simple components (screws bolts etc).

It would semi-need to be plugged into a laptop for obtaining the raw data, although there could be alternative modes that feedback information to a simple multi-line display without a laptop. Ie absorbance, good for concentration vs absorbance experiments. | It would semi-need to be plugged into a laptop for obtaining the raw data, although there could be alternative modes that feedback information to a simple multi-line display without a laptop.

* This should be easy to fit into the confines of the competition, although I personally hadn't thought of a portable power supply it should be simple enough to incorporate. I have ideas that I will try and outline soon to help development. [[user:ciaran.mooney|Ciarán]] | |||
* Is that a machine to find out what elements are in a sample? Like a mass or IR spectrometer? You can make those? [[user:MonkeyJam|Daniel]] | |||
** Well it is usually used for chemical identification, though some decent analysis I'm sure you could do elemental analysis. This would be a visible light spectrometer, a mass spectrometer is much much more difficult and expensive to make (£100,000's). I'd like to attempt an IR spectrometer in the future but not at the moment.[[user:ciaran.mooney|Ciarán]] | |||
** But yes you can make visible spectromerers, relatively simply. They can also be useful rather than a toy, I hope! [[user:ciaran.mooney|Ciarán]] | |||
I'm not sure how components will be obtainable around the world, but the designs would mean that alternatives could be made from other materials. There is no need for it to be MDF. | |||
