What?
A visible (possibly UV) spectrometer, the design of which (circuits, CAD, software) is open to all.
Why?
Those that are available for schools are too bloody expensive, given the level of technology they contain.
How?
Design will be based on a Czerny-Turner design.
Probably contain an arduino, cos they get you extra blog-cred.
Parts
- Cuvette Ebay ~£25 inc P&P
- Concave mirror * 2 (£16 each) ~£47.40 inc P&P
- Diffraction grating ~£10 inc P&P (for 10 1000 lines/mm) - can get cheaper from Ebay..
- Sensor (photo-diode) ~£1, have one in electronics kit.
Total = ~£85
