In this case, why even the more basic astronomic camera comes with a IR filter?

@Vanadium 50 :O I didn't know its called a Dark Box. I don't get very well why so much black, a normal black would convert visible light to IR, which is not nice for a Dark Box, this could be improved with other ppl advice on materials. mm, after some thoughts, is not necessary reduce the...

So, let summarize to know if we are going good. To block Normal light, use black. To block UV/IR use carbon, I was able to find carbon paper, is cheap so it can be used. How is the blocking working for carbon? The light can be absorbed, reflected, transformed. A normal black thing will just...

I can't found any, not expensive foam with carbon black, at least here, they are pretty expensive, and sell in not minor amounts. How works aluminum here? IIRC it can emits light with some charged particles, but maybe a wood box that is cover in aluminum could be a good use?

mm, the sensor does not need to be inside, while we are able to measure what is inside. Putting it out seems a nice idea, avoid not only light, also other particles that could also cause small light. I just started checking this case, of a more sensitive photon counter, I was able to confirm...

The camera is able to pick at least from 300nm to 900nm, is little wider than the visible light band, if black is the only needed could be an option this spray of almost perfect black. Wood is cheap here, so is a very good option, IIRC also has low therm conductivity. The camera will pick at...

Hi! (newbie here) I'm doing a experiment, very simple, in the center of a box there is a light source, a small one, and closer is a photon counter device. The challenge here, and the hard DIY part is the box. The box can not any photon get inside, nor emit any of them. At the same time it...

Here the 3 set of equations we know, the Maxwell Equations, Lorentz Force, and Coulumb Force, actually I doubt a lot what set of equations represent all the electromagnetic aspects, I try research over the internet and I found a lot of contradictions in the answers, someone says we can get the...

Hi hi, here a question, how can we prepare Potassium sodium tartrate?, well, there is a lot of sites and videos, but in order to this right I'll write what have I done and checked, I'll try use the info I have, even if is not very dependable. First, we need sodium carbonate, to do this, we can...

Thx!, this was very very helpful, now I think I can use the transformers here, and test them when I need.

:O Ty, so, a transformer don't come with resistance? or just too low?

Hi hi, I was trying to use a transformer, that typical transformer that we have in house for a project, but then I notice something, well all this can be just a misunderstand from me. Actually a transformer have a voltage and a current, at least that is what it says the labels, "18V and 3A" for...

The question is how to get the distribution of this... The game it self is pretty more complicated this is just a simplified version, if you put cost and a lot of more things it takes sense, but the game it self is not the focus..., there is a lot of costs and other things. The point is not...

You can playing forever. Just when the count reach 0 it start again and we get the 10 coins, you can continue playing. The coins are accumulative, don't start again, even if the count reset. Yes, 10 coins when we win rolling the dice :3

##n## is the start number of the count, when it reach 0 you win automatically and start again, will decrease by 1 in every roll. ##coins## the something that we want to get, more coins better! ##m## the amount of coins we get by winning 1 time. This a game where the only options is win or...
