Back in the day we used to service loads of AV equipment in a college over the summer.We had a home made compressor/air pump.It didn't have a reservoir so you just switched it on and a hose blew air. I don't know about moisture content but we would just wave the end inside the OHP/carousel and blast dust out. Thinking about it, I have a car jump pack with tyre inflator that came with a thing to blow up footballs.

Only thing is that both the diy compressor and battery pack made the heck of a noise.

Given hire costs, buying a load of cheap Amazon home projectors might be worth it? https://www.amazon.co.uk/ELEPHAS-Projector-Portable-Display-Compatible/dp/B07N39NDDB/ref=sr_1_2?dchild=1&qid=1611411442&refinements=p_89%3AELEPHAS&rnid=1632651031&s=home-theater&sr=1-2

I saw something like this being used by an art student, I was amazed by it's price and built in media player

You could sell them on at the end of a project - it would cost you a grand but worth considering.You could buy one as a trial, and if ok buy and have the projectors delivered straight from Amazon.If not, return the test package.

Hire cost plus £10(?) per projector delivered to each person will add up

If you didn't already have the blue ray , I'd buy something like

https://www.thomann.de/gb/denon_dn_500bd_mkii.htm

run the outputs to a normalised patch. Connect the amps to the sockets underneath so that the patch field with nothing connected just works.

(Even if you have to hide the patch leads) Then for a show connect to the desk with the leads.

Even if you accidentally leave the patch in, a phone call can tell the projectionist to simply unplug everything on the patch and it would work

Redheads or Blondes are's that hot when bouncing off an 8x4 poly sheet. Distance aids cooling.

The Glasgow fire was fumes that were released by foam in a can, being used to fill gaps in poly sheet.The projector provided the ignition

I was discussing this today.Apparently the series "staged" (I haven't seen it) used the actors' phones for the audio.

If you were close enough (say the next room?) Could you run a camcorder through a capture card/ BM recorder/elgato capture into your computer while recording in camera?Is there the possibility to do the same at the other end as well? And post the SD card or Dropbox it?

We are supposed to use teams at work but prefer zoom. Teams does all sorts of flickering and reshuffling the pictures for me.Not sure if you can pin each speaker and make a recording of one individual one one computer, and the other on a second computer? I could have a play tomorrow? You might need to give each person joint host status so they can record?

Edit- if each person participating could cope with not seeing themselves, they could pin the other person? Do a local recording on their computer and send it to you? (Along with better audio?)

Some sort of manufactured door? Plenty of cases have side doors. You could cut a hole in each back and mount a door trough 90°?Orhttps://www.flightcasefittings.co.uk/hinged-rack-panel.htmlModified to fit a hole cut in the back door of the case.Potentially with a brush strip added

If you wanted to go for the "hole top and bottom" I'd go for simple desk cable grommets? Maybe a high quality type, but easy to source and operate

The ATEM software is actually bloody good.I tend to think the issue is that you can't hear what you are doing?

You can run another computer on the network and monitor the sound in a better environment - that would help a lot at minimal cost

No real experience but could the wall be built into a "shop window" style arrangement where it's actually indoors? It might even be as cheap to use an indoor video wall and make a window?

Black magic converters are great and a quality product but the el-cheapo ones on Amazon at £25 or so work pretty well.

If using a vacuum cleaner, ensure it's class H or better.Otherwise you could be just pumping fibres in the air

My old pipes and guttering were painted and it's quite a safe material. Nevertheless I did have all the windows open in my (estate) car.

If disposing of a small amount of asbestos.. (based on about 5 years ago)

I got rid of asbestos cement downpipes and offered to transport my 90 year old neighbour's ones as well.Double bagged in heavy black polythene and gaffertape in my version of a Soprano's body disposal.

The dump needed a phone booking for a time slot, checked that it was all from my house. As soon as I mentioned my neighbour, they insisted either I brought him along, or paid a pro disposal rate. I said I'd ring back and waited a couple of weeks before ringing again and saying it was all mine.

If you have a small amount, and are happy to lie a bit, carrying double bagged stuff in your vehicle (roof rack?) it's far easier to dispose of a small amount as a domestic client than the palaver of professional disposal

Our building is late 40's and riddled with asbestos. Every now and then they clear a bit using extreme measures and it's good to know they take it seriously but it's very disruptive.

A venue I worked at had a safety roller curtain and a senior usherette would often hand over a bunch of flowers on stage. She died of asbestosis, and legal proceedings ensued.

Might work with zoom webinars?I know that you can have panelists, and participants.

Think of an audience, and a table of panelists on stage. You can promote any participant to panellist, and remove them, there is a limit to panellist numbers afaikSo if it was more university challenge style than free for all, you could ask teams to answer questions in turn.Afaik you can use chat to talk to individuals or everyone.

So if there are 20 teams, plus chair, how many people are in a team? And are they together, or each on their own pace?

I know you wanted bare, but 8 way

The reason I was asking is because I have been involved with a couple of promenade performances where they draped polythene for a post apocalyptic vibe.

If you could remove the logos from the areas that face the audience but keep it where it touches the ground or up in the rigging it would be handy

Is the branding removable ? Water based ink? Solvent?

Surely by "free standing" it relies on the floor?

A basic multi legged "table" structure can support a reasonable amount and probably needs no bracing to the walls or ceiling.If you felt safer, a simple overhang that is close to the walls would prevent it tipping

Zippo/swan lighter fuel is pretty good for this sort of thing.Just don't smoke when using it

Bit of a faff- plus £500. But it does free up the output to record. However you'd lose the actual display on the pro/iso for streaming.

The atem is quite impressive- especially for the money.I started with Shibaden and National (Panasonic) mixers- genlock etc.

I also have the atem television studio HD but it's bloody fussy about resolutions.

I have bought a streamdeck to allow use of macros via companion. Also-" here to record " offer a title software that's chroma key based. I guess you could run PowerPoint with a green background. There is a development using a rasberry Pi to emulate a hyperdeck so it can be triggered by macros

There is something about the atem input 1 that's different you the others, but I can't remember what it is. Maybe colourspace? Is the cheap splitter at the projector end? Or the atem end ?

EDIT input one is YUV only

https://www.haguecamerasupports.com/aerial-masts-powerheads/hague-ph-pan-tilt-camera-powerhead

I have used these for years. I have run 100ft+ extension leads for the remote- although it does require manual operation.Jesops used to sell them cheaper than Hague and they are available all over the world so quite possibly available at low cost

Are you aware of reversing rings? You can get a reasonable macro out of a a standard kit lens on a canon dslr (d700)From memory less than £50 and you demount the zoom lens, stick the adaptors on each end, joined by cable, and fit the lens again.Because the lens is now reversed, it gives a macro result.

You're not going to win wildlife photographer of the year but with care you get good results

It doesn't answer your other questions but may help
