Sorry but all you demonstrated was the effect of light refraction through a CD. That was not the subject of Young's double slit experiment.

I threw all my clamps on a shelf. Free and took me 2 seconds.

I would have started on the rust with Electrolysis and then a wire wheel on either the drill or an angle grinder.

I designed a very similar clock back in the 80's using discrete components and no software. But, alas, I never built it.

concrete is a good choice of material because birds don't want a slippery surface but the shape of this bath is not ideal. Birds want very shallow water to wade in rather than a deep "bath".

Nothing has been done on this in 7 years. It should be deleted.

Always wanted a light table when I was younger, before scanners & drafting software etc. Still tempted to build this.

I like it!!

I'm not proficient in Andruino and it seems to me this could be done with discrete components....maybe. Anyway I like the whole concept.

Huh?!

Nice work.

tadam?

repurpose an old desk lamp, maybe?

Yes, excellent!

I like it. There are other ibles that have frosted glass or lights behind the glass but this is nice. I see it was not an option for you but I prefer a headboard mounted on the wall.

Nice! I'm just wondering if I could modify an existing office chair since I don't weld.

what are you supposed to do with the cross?

no proof of concept.

You have great ideas but your instructions are lacking detail.

Unfortunately, it's not the preferred method on this website.

Me no drink bleach. Taste yucky.

Never said it would kill you, but can make you sick.

I guess its ok to skip step 6 since you did.

Could you be more descriptive on step 6. I feel like I missed something.

Wod should never be used for a cutting board because it holds bacteria.

Where do you see an open pipe?

Yeah, well that's why I called it "solar".
