Sweet!

I've been fiddling around with my idea and came up with some better drawings.

The half-circle is a pivot that will hold the diffraction gradient so I can play with angles. I also need to add a spot for the test tube somewhere along the thin light slot.

The camera would be on the left half, the flash on the right half. There will likely need to be the 2 razor blades to get the proper light slit for a clean rainbow image.

Kinda an upside down view so you can see the bottom of the diffraction gradient pivot.

Any thoughts before I print the first iteration out and see how horrible it works?

I listened to a fascinating story about 3D printers on the radio a little while back and how scientists are succefully printing DNA and experimenting on human body parts using a special kind of ink. Technology spins me out.

If only we knew someone with 3D printing skills to add to the member skills thread.

3d food printers are the next big thing;

all i can say... is yikes!

This showed up in my news feeds - thought some of this threads followers might get something from it.

This might be useful to create laminar flow for the test water.

I have DLP 3d printers if you ever need to print in AU

looks like i will be working on something like this soon for Ammonia/Nitrate/Nitrite sensors

What ever happened with this? Bump
