As it was the last day of the holiday season I decided to clear away a few things, at the bottom of the pile on my desk was a plan for a spectroscope which I had downloaded from http://www.iucaa.ernet.in/~scipop/Obsetion/spectro/iucaa_mvs_spectroscope.pdf, printed out but not got around to mounting on card and putting together, so it was now or never.
Here are the results, it took me about 30 minutes to construct, a fun little project. I then proceeded to run around the house looking at all the different light sources I could find like a kid with a new toy on Christmas Day!
The photo of the spectrum doesn’t really do it justice, some energy saver light bulbs had definite strong lines whereas others had a more even distribution across the spectrum.
This is something I could get quite interested in, watch this space in case I can translate that enthusiasm into something tangible.
