Not a video yet. This one's for the high voltage geeks

PBS Spacetime, Abroad in Japan, Tim Traveler, Technology Connections, Techmoan, Tom Scott, EEVBlog, Veritasium are some of my favourites.

I've got a 40kV source available here (working from home), might see what kind of glow I can photograph.

Mike Page

Most of the astrophotography stackers are designed specifically for that purpose. In this case, simple averaging would suffice, which is what a lot of cameras (and some phones) do in 'night' or 'noise reduction' mode. Open Camera has an NR image stacking function, though I'm not sure how many frames it stacks.

Mark Gray

Stop I was looking at Eagle model kits just the other day! I love that ship!

Michael Thompson

Before or after Moonbase Alpha passed through the black hole?

Peter Laws

off topic, but looks like a picture from a space 1999 episode ;)

Scott Traynor

there is open source software that takes care of it for you, its not super processing heavy but you need a reasonable system to complete them in a reasonable amount of time

GL_1_Code1_1A

Sounds very time consuming for processing the shots.

Big Clive

I don't often do screenshots, but when I did try I had no luck.

Big Clive

Have you considered using a technique photo astronomers call stacking? Taking lots of frames and stacking (averaging) them after aligning to take out movement? Good for faint "objects". Me, I'd use a tripod and Bulb mode.

Mike Page

The only thing I found different about a screen shot with the BV pro is the duration of the double press. My older phones it was almost instant, with the BV I have to hold the volume down & power buttons together for over a second or two. Then I get a prompt to save which is also new to me.

Jim

Clive, have you mastered taking a screenshot with the BV9900 Pro? I've succeeded sometimes but most of the time it doesn't work!

Mike Hanley

Here are some more ideas, all of whom have good production. :) Aging Wheels, Under Dunn (by the same guy), Tom Scott, Technology Connections, Pask Makes.

Michael Dunn

The tricky bit is PROVING their claims about producing high quantities of hydroxyl radicals (one atom of oxygen and one of hydrogen). Even a well equipped lab might struggle to analyse something like that. Then again, in the UK you can buy "anti-aging" beauty creams from high street stores.

Big Clive

You should look at Peter Parker vk3ye. He is very different but I talk to him on air a bit and did a ve exam with him

Simon Deards VK3FSPD

Excellent. Thank you so much

Simon Deards VK3FSPD

Big Clive, Ashens, Scott Manley, Hydraulic Press Channel, Ham Radio Crash Course, OfficialSWLchannel, Mr Carlson's Lab... and I will make this the "short list" because there are some inactive channels I can't bring myself delete like Photoninduction.

Michael Thompson

What other channels do you all watch? I spend evenings watching YouTube but much is not upto @big Clive’s standard. I watch eevblog, techmoan, 8 bit guy, Fran lab and some ham radio channels. Oh and now ralfys channel. I can’t stand crappy video and audio quality

Simon Deards VK3FSPD

They would get fined in Australia for making false claims. Big companies get fined regularly

Simon Deards VK3FSPD

Negative corona produce more Ozone than positive corona maybe this explains why they made it different? Wikipedia has a good article on corona discharge.

Tokkan FX

There seems to be a whole science on how deep to bow. But apart from that, wearing masks and keeping distance does make a lot of difference.

Frank

-and if you act now Big Clive will include this collection of hits favorites, "Medley of Molecules" on 8-track and cassettes!

Michael Thompson

Now you kind of have to, don't you? LOL ;)

Michael Thompson

Softens skin. That is so absurd! As for Covid in Japan, it probably has more likely has to do with the fact mask compliance is 100% and that culturally, people don't touch each other. (And bow instead)

Adrian's Digital Basement

It will definitely produce a whole medley of molecules by splitting existing ones in the plasma discharge. Nitric acid will be one of them, but at very low levels, noting that humans actually produce nitric acid internally as part of the cardiovascular control system.

Big Clive

My favourite bit is how they pull hydrogen atoms out of viruses and then convert to water which then softens your skin. One really important thing though is that they are an iconic thing in Japan and just about every house and public building has them. So they've been doing a very convenient long term ozone test to observe from a distance. Given that ozone does deactivate airborne bacteria, I wonder if that's a factor in their lower incidence of covid.

Big Clive

I may experimentally build a pair of identical positive and negative ionisers to see if there's a difference.

Big Clive

I think a lot are based on the Plasmacluster products. The positive/negative thing is a bit suspicious. I think it may be theatre to hide the true function.

Big Clive

Well if it is producing ozone, then it’s 100% producing nitric acid also, because they’re not using any type of dehumidifier or dryer system.

Mike Wynne

I was watching a video the other day about Sharp Plasmacluster air purifiers in Japan -- and the marketing speak was SUCH CRAP. Silly claims about the plastmacluster increasing concentration after 15 minutes or some BS. I guess Japan has no rules about truth in advertising!

Adrian's Digital Basement

I'm guessing the difference in brightness is just due to the single polarity pulses like you mentioned, I doubt you'd get any other kind of polarity weirdness unless this was running in a very low pressure atmosphere where you'd start seeing "anode rays" and other phenomena like that.

Shame Boy

I have some similar German units. I believe the idea is to create both negative and positive ions which somehow cancel each other out, which makes no sense. They are very low power with very faint discharge meant for mounting in ventilation ducts.

Bill Kerr

This module is from a unit I took apart a while ago. You can find that video here:- https://www.youtube.com/watch?v=re4F-_FGFvI

Big Clive

Absolutely tiny amount of current. 12V module supply at 35mA.

Big Clive

All of the voltages, but I try to keep with current events too!

Michael Thompson

High voltage geek here: waiting with bated breath! More please!

HarveyB

High Voltage is Fun 🤩!!!

Zane Revai

Oh! High Voltage, that's my work!! Be mindful there! Low amp though, yeah!
