It's a VEVOR 50W CO2 power supply

The Radiacode detects Beta and Gamma. Alpha traces are optained through secondary x-ray emissions or Bremsstrahlung

Exactly that was my intent, easy replication without highly specialized equipment. Let me know how it goes!

@@ralfschooneveld3186 Unfortunately, no. I think you'd have to go through some multiplication stages to go up that high.

@@BalticLab Ive got a paper where thery went up to 0.1Thz and 0.48Thz, but no details. ''Frequency multiplier units based on SBDs, impact ionization avalanche transit-time devices (IMPATTs), tunneling transit time diodes (TUNNETT), and resonant tunneling diodes (RTDs).

@@ralfschooneveld3186 That would be 100 GHz to 480 GHz, no need to express that in THz. Though many research papers want to push THz, so they use stuff like "near THz" to push keywords.

I lice my PCB traces intact :-)

Thanks for your comment. Especially for DIY, electronics (and other science related) topics, it'd be hard for creators to post highly original content that hasn't appeared anywhere else in some shape or form. And I think it's perfectly fine to post ones own version as every creator has a different take on things, a different presentation style and focuses on different aspects. Also, topics such as this are easily researchable if the person is aware of what to look for. Many people do not know that they can receive weather satellite images themselves. So of course this is interesting for people who never stumbled across this before. That others have done something similar, or highly adjacent, is something I frequently mention in my videos because - unlike other creators - I actively encourage viewers to look around other channels. People like different presentation styles and formats. So if someone finds a different creator after watching this video, who better matches their prefered style, I am happy for them. From my research I am the only one showing a very simple V-dipole directly into a RTL-SDR on a Windows PC. So while the topic isn't new, this is a differen take on things.

Eagerly anticipating your video.

The output is the desired signal, the counter-pin, or reference pin, is ground.

I honestly don't know but some viewers indicated that its the same for tue 8900

You can limit the current to 1 mA by adding a current limiting resistor in series. Just make sure its appropriately rated for the voltage and the dissipated power.

@@BalticLab Okay I'll give it a go! Thanks for the reply!

Unfortunately, that is true. I now have a Radiacode 103 and the differences are quite significant: czcams.com/users/shortsAVM8EzvVCiI

@@robert48719 Basically 😅

I wish!

Hi! That's probably not a good method for measuring flicker noise as thermal noise us the reference, yet all test equipment will bring it's own flicker noise issues with it.

It's an aqueous solution with NaOH and hydrogen peroxide. Basically the standard luminol recipe except with multiple, unstirred fluorescent dyes at once.

​@@BalticLab can you write a concentrations of the solutions, please? I'm looking for a colorful experiments for kids and I will be very grateful if you send an experiment setup

Thank you. Glad you liked it!

@@BalticLabloved it. Can you a video of adc and i2s too? Thanks

I'll put it on a list. My top priority item right now is to redo this video a bit more modern.

@@BalticLab that’ll be great. Appreciate the efforts

Here's the code: baltic-lab.com/2023/08/tremolo-dsp-effect-for-arduino/

I already showed a Ku band transmitter (czcams.com/video/jWDu2BkVWnw/video.htmlsi=5riGTQkg_tibKkyl) but a teardown of the BUC would indeed be a great idea!

An RF supplied CO2 laser is much safer and compact and servicible but more pricey.

Btw I still remember your Wilkinson combiner tutorial about 7 years ago. I still rely on that knowledge for my RF designs ;)

Good to know. That Wilkinson video apparently has quite some popularity I was invited to give a lecture on Wilkinson design at a local university recently after many students referenced my videos in their lab reports. 😄

Yes, because delivering Information clear enough to understand is highly appreciated.

Actually a great idea. With the depth and complexity of RF I will have to think about how to best do that, whether it's gonna be a 1 hour video or 10 segmented videos. Maybe a combination, a teardown vid followed by derrivatives of interesting features in the design.

It's double sideband modulation for the 38 kHz subcarrier. This modulation type stacking actually happens a lot. FM subcarrier modulated onto an AM signal is used in aviation VOR stations for instance.

Yes indeed. Actually, one of my very first videos was an old C-band LNB teardown video, huge difference: czcams.com/video/DkURL4mETT4/video.html

Duly noted!

That's a very interesting idea.. Since I have an outboard engine on my sailing yacht, I'll put that on my to do list for interesting ideas.

No Problem, I have absolutely no problem directing viewers to other channels if they make great videos and you sure do! Thanks so much.

Correct. I know that now but I don't censor my mistakes afterwards, it's part of the journey. :)

Agreed. I was hopeful that the price will drop after the Giga is more estabished but so far it's quite pricey. The Arduino Uno R3 might be a new, inexpensive but powerful alternative. I have one here and will check into it.

Glad you found the video helpful! P.S. Been subscribed to you since whenever I discovered your channel.

@@BalticLab Haha, tnx!
