Hello,

Very interesting indeed. Too bad that we do not have the tools at home to make those.

The ideas of monsieur G4Lab to improve the last product are good points. If we decide to buy the tools to do that at home, I will use a piece of magnifier as he suggests.

Thank you everyone for sharing.

Brigitte

The spectroscope (spectrophotometer) and associated software is available both as a self-contained kit with a USB plug or as an add-on to a smart phone camera. The description asserts sub-3 nm resolution (not too bad) and software seems to be available for windoze, linux, android, and iOS. I might try it out as the entire portable unit is only $39.99 at the maker shed web store http://www.makershed.com/Desktop_Spectr ... kpbl04.htm or direct from the inventor at http://store.publiclab.org/products/des ... metry-kit; OTOH, the smartfone version at http://store.publiclab.org/products/sma ... ectrometer is available for $70.
