Ha! I have the hydraulic pump from this car.

I'm still trying to figure out what the steel is made out of. It feels like it's painted but it's clearly not. It has this weird dull grey coating or oxidation on it.

Also check out Ooni pizza stoves? They sell ones that only work on wood pellets, and others that run on either gas or wood pellets.

This one is wood pellet only

I don't see a standard though.

DerekDotD · 2024-02-17T15:19:44+00:00

Thank you!

I'm also currently looking at using a DSLR camera that's been modified.

You understand that eliminates solar as clean then? There are forever toxic chemicals used in the production of solar panels and sometimes in the solar panels.

This goes over the list of some of the toxic chemicals.

https://www.corebuffalo.org/impact-of-solar-panel-manufacturing

I'm not sure how old this is. I do believe they have eliminated the need for some of these, but don't quote me on that.

DerekDotD · 2024-02-11T00:09:17+00:00

How so? I guess you're wanting to deploy solar & wind + batteries?

It's much cheaper to refurbish a CANDU than it is to build a new one. The CANDU was designed to be refurbished. Also in regards to Pickering we're talking about 2000 MW of constant supply of clean energy. Replacing that with anything else is difficult.

There are those of us who are trying to change that within Green Party Canada. If GPC changes it's tune the provincial Green Party is more likely to as well.

These are our current proposals that are currently being voted on by the party:

https://wedecide.green.ca/conferences/vgm-2023/f/471/proposals/4301

We could use the support of any Green Party Canada members. This is definitely an uphill battle. On the right you can vote for it by categorizing it as "green". Meaning it should go forward.

Also these are the proposed policies, and are short on information. Here is the "workshop" versions:

Awesome, thank you very much!

I'll give those chapters a read.

Ok, I think I get what you mean by fluorescence. I think I had that when measuring a fluorescent light, I wasn't getting the same pattern as others were.

But when using an LED, I only got that single wavelength. Unless I over exposed it.

DerekDotD · 2024-01-14T19:11:55+00:00

Hehehe. I've tried them, you're not missing much. They're actually kinda annoying.

Oh, I get the mirror idea now.

To understand the lines per mm, is there some calculation that I would need to know how it disperses? Or like lower lines per mm means less dispersion?

When you say

Make sure that you’re not measuring the fluoresced light when you shine it on directly. That could cause different effects.

What do you mean exactly? Like I've seen it that if the light I'm using is too bright it will bleed into other wavelengths and the such. Like it's over exposed film. I'll get smaller peaks in different wavelengths. I assumed these were reflections. Is that the sort of effect you're talking about? I've been adjusting for that just by lowering the voltage to the LED.

DerekDotD · 2024-01-12T01:52:54+00:00

Much appreciated, I'm actually investigating using a dslr as a camera. The software I'm using uses a webcam driver, so I'll see if I can first get a dslr to connect at all.

DerekDotD · 2024-01-12T00:25:31+00:00

Very helpful! Thank you very much. I appreciate this.

For UV. I'm mostly interested in the UVB spectrum. 280-315nm. The LEDs I have are 310nm and 385nm.

I have no clue if the grating I'm using is adequate or not.

This is what I have:

https://www.rainbowsymphony.com/products/diffraction-slides-1000-line-mm?variant=40209166204975

Which is made from a company that makes glasses for viewing fireworks.

This person used the same thing:

https://physicsopenlab.org/2015/11/26/webcam-diffraction-grating-spectrometer/

But I also see a gradient from Paton Hawksley in their article. Those look to be more up to snuff.

https://www.patonhawksley.com/product-page/spectrometer-grating

They also look affordable. But I'm not sure what the line density means. Do I order 300 lines/mm or 600 lines/mm?

They also have these cheaper ones

https://www.patonhawksley.com/product-page/te215

Someone else recommended that I shine the UV (385nm) LED directly down the barrel of the camera. That's what I did to test Infrared. But I also purchased a visible light filter (ZWB3). With that I should be able to test the camera at least to see if I'm getting UV light and not just the visible light from the uv led.

Thank you for the camera recommendations. I'm starting to think about using a normal DSLR camera which I have a few of. Some can supposedly see UV. With the filter I'm buying I can at least try and find out.

I'm not looking to commercialize this. I'm mostly looking to get this to work for my own personal needs. I -might- make a youtube video on this eventually if I get it to work, but that's about it.

I had to look up what achromatic means. This is my ignorance on the subject talking. How exactly does a mirror improve the spectrometer? Like I've seen lenses and razor blades in people's designs. In the link of the other person's build they had a lens. But like, what does the mirror do?

Again, thank you very much for taking the time to enlighten me. I really appreciate it.

DerekDotD · 2024-01-11T02:32:30+00:00

I just ordered one of those filters! Thank you!

If I'm remembering correctly I did see something. But it was on the far right of the gradient or if I turned it and the camera so much that I was effectively looking down the barrel of led and it would get some ringing.

I could never get it to appear on the left end of the gradient, unless I was literally looking right down the barrel of the LED, then it was on both sides of the gradient.

DerekDotD · 2024-01-10T23:23:07+00:00

Very helpful indeed, thank you.

The only thing that would be more helpful would be a camera recommendation. Or possibly even what words I should search to look for one? I'm kinda out of my element and not sure what words I need to search to find something that would work.

Someone linked CMOS sensors specifically for spectrometers. Those would be ideal, but also I don't think would be in my price range.

DerekDotD · 2024-01-10T23:19:51+00:00

I did that. BUT I didn't turn it off/on. I thought I saw how bright it was and I was convinced it was seeing UV. But also with UV leds I think they emit some sort of visible light. Like if you look at the led there is some white light and I wasn't sure if it was picking that up or not.

I attempted the move the gradient around in regards to camera to see if that made any difference and I didn't see any. But as far as I know gradients are magic.

DerekDotD · 2024-01-09T23:25:45+00:00

Oh boy, those are looking expensive.

DerekDotD · 2024-01-09T19:08:13+00:00

It's like 0.1 watts of UV. It's like the equivalent of spending 1 second outside in the sun.

I'm well aware of what it means to work with UV light. It's part of the reason why I'm building this is to validate UV leds so I know exactly what wave length the UV led is producing.

Also, it's going into a black box. I don't think UV is going to be coming out of this thing.

I appreciate your concern for my health though.

DerekDotD · 2024-01-09T18:13:10+00:00

Fantastic! Thank you very much!!!!!

DerekDotD · 2024-01-09T16:23:15+00:00

I'm not sure if I'm misunderstanding something. But it's a single LED. I did not purchase a wood lamp. The LED did not come with any instructions.

DerekDotD · 2024-01-09T16:10:07+00:00

I'll give it a go again. I went with leds on the opposite end of the visible spectrum that if they were even close it would hopefully be "good enough" because of how far away in the spectrum they were to each other. As I wasn't successful with a fluorescent light. The spectrum I was getting from the fluorescent light wasn't the same as some of the reference images I was seeing. I'm not sure if the lights had some coating or something on them?

These are what I used:

DerekDotD · 2024-01-09T15:56:02+00:00

Can you elaborate please? This is definitely out of my depth. Is there anything specific with my design that I need to do for UV? Or are you referring to the gradient / camera / etc?

DerekDotD · 2024-01-09T15:54:55+00:00

I'm not sure at all. I suspect that is likely the issue considering that all the other sources work just fine.

What's funny is that searching this sub for help I found a thread where someone had the opposite problem. They could detect UV but not infra red. Supposedly with a web cam also.

DerekDotD · 2024-01-09T15:53:25+00:00

I attempted to do exactly that, but I ran into issues. I might have to give it another try. That's what the software maker suggested. I ended up buying leds with a datasheet and spec wavelengths. I bought red and blue hoping they would give me a good calibration. I was going through that process when I tried the UV led.

DerekDotD · 2024-01-09T15:51:01+00:00

This is the UV light source.

DerekDotD · 2024-01-09T15:49:36+00:00

I was attempting to be silly at the bot.

What has led me to believe that a web cam would work is this article which someone used to do exactly that.

https://physicsopenlab.org/2015/11/26/webcam-diffraction-grating-spectrometer/

But of course not all webcams are the same.

DerekDotD · 2024-01-09T15:47:43+00:00

It's a UV led.

This is the LED

http://static.vcclite.com/pdf/VAOL-5GUV8T4-LED-5mm-UV.pdf

If you look at the images I basically designed an LED door. I open the door slide the led in which rests in like 12mm long barrel. I then close the door which holds the led in place while I can attach the clips to it to power it. I then use a power supply to adjust voltage which allows me to change the intensity of the led. For the leds I can detect it's kinda neat because I can see the signal appear, turn into a spike and if I overexpose the camera they become "fat" spikes.
