Patreon backstage snippets

Some random bits of video from work.

Just a quickie

After the video I found four tiny components hiding under the silicone sleeve around the charging connector.  A decoupling capacitor, two resistors to enable USB-C charging and a mysterious diode style component with hard to read marking.

Inside a Space Flower

We have some unusually retro lights on the job.  This one was delivered with an unusual pan fault which may have been caused by a repair attempt in the past.

https://youtu.be/X5oCjCujCyM

This light uses a 3kW xenon projection lamp to shoot a mass of rotating and morphing beams of light into the sky.  It requires Civil Aviation Authority approval to use.

Radical new light

It's rare that I get excited about a new lighting fixture.  But this waterproof Cobra light uses a high power blue laser to stimulate phosphor on a spinning disk (it spins for cooling reasons).

It produces a super-sharp point of light that is processed through a very narrow optical path with a gobo wheel with multiple tiny 4mm images on several concentric circles, and the normal subtractive colour system.

This thing slams out a super-intense beam of light that can easily proj...

Pandemonium at work

I'll try and catch some video snippets, but right now the chances of filming anything are restricted by the amount of work and the timescale.

Things should hopefully calm down soon.

More glorious eBay poop from China

This is a good example of when text is copied and pasted out of listings for similar products.

You also get to see the very basic crew bathroom.

Failed safety lamp holder

Quick video before going to bed way earlier than normal for an early start to begin the show load-in.

https://www.youtube.com/watch?v=7NY5KGZ-Qqg

This is an unusual style of safety lamp holder that had failed.

First video from the crew accommodation

Setting up a recording area in my crew room was very tricky.  I've improvised by stacking random bits of furniture, adding a recording surface designed to avoid reflections and used a twin pack of pillows as improvised sound reflection damping.

https://www.youtube.com/watch?v=_GOWsFTQaYU

This is a start, but I need to use colder white lighting and nudge the white balance a bit for more natural...

Mini USB flame lamp

The very short loop on the flame effect detracts from this light.

https://www.youtube.com/watch?v=mtxcWmjYJDo

It's begging for some new software with randomised effects.

Test Patreon stream from Edinburgh

I'm calling this a test stream because there's no guarantee it isn't going to turn into a buffer-fest.

https://www.youtube.com/watch?v=iYBygrpfY48

There's no good 4G connectivity and of the two wifi networks available, one is for university students only, and the other open one may be a bit unpredictable.

Inside a Tesla headlight

Taking this apart on the evening of the day before a flight was NOT a good idea.  But once I started I had to finish.  Even if it did involve some very severe angle grinding of plastic to open.

https://www.youtube.com/watch?v=_toknJIOhEg

They're really not designed for service.  Although I reckon this whole light could have been fixed with just the changing of the removable electroni...

100W and 300W honeycomb "mine" lights

Darn!  I made quite a few goofs while making this video, because I was trying to record it quickly before travelling with work.

https://www.youtube.com/watch?v=Z7E_GDQI6M0

Interesting lights, but using the common and very flickery unsmoothed linear regulator approach.  The heat radiated by these lights is surprising for LED.

They do have good customisation and hackability though. 2022-07-11 08:49:48 +0000 UTC View Post

Inside an Otis door operator

Something well designed for a change.  The Otis stuff tends to be well engineered, and this is quite a pleasing unit.  It's a universal door operator controller designed to drive a beefy 3-phase door motor from an integrated variable frequency drive.  It has to be strong, because it drives both the elevator car doors and landing doors, which can be quite heavy.  It also has to be able to close them slowly at end of travel, while still engaging mechanical and electrical int...

Inside LIDL's rechargeable work light

While functional, this unit has some squirmy things about the design.

https://youtu.be/JiTds3Bd4YI

Given the choice between the LIDL and Aldi version, I'd choose the Aldi one.

I did a proper experiment

To see if a standard zinc air cell works as a gas generator I put one up against the cell from an air freshener to see how they compared.

https://www.youtube.com/watch?v=TNjPHkfk1-Q

Very interesting results.

Right, that's me done with the zinc-air hydrogen experiments.  Back to normal content.

MBC Independence Day Live Stream

For those of you who aren't partying, here's an MBC stream.

More trash wine clickbait

This video reminded me of the peril of using Android apps to record videos.  At some point there has been an update that reset the default microphone, depriving us of the fizzy goodness when I held the bottle and glass up to the completely inactive microphone.

https://www.youtube.com/watch?v=5-inafP-3zw

On a plus note, the default mode (camcorder) did a decent job of catching most of the audio...

Chinese Rubber Maid

Even China knows that westerners want their maids to be clad in high dielectric strength attire.
It's apparently "lockable" to prevent your maid escaping.

Live now.

Make sure you check YouTube hasn't started you at the beginning of the stream.

The big firm ribbed RUBBER-maid "thing"

I had a drink.  I made a video.  NO REGRETS.

Curtain controller with rogue spicy wire

This video is more a heads-up to the possibility of modules like these having uninsulated antenna wires that are mains voltage referenced.

https://www.youtube.com/watch?v=Uw8bqNMadJA

The module itself controls two relays switching mains current, and accepts input from manual switches, wifi or a 433MHz remote with the option to program separate open and close codes.

Rubbermaid (ooer!) gas generating aroma unit

This was a full-on rubber glove and Dremel teardown.  It's not going back together any time soon.

https://www.youtube.com/watch?v=W9eHzYrmIX4

I've got the bigger version on order too so we can explore it as well.

Cheap eBay fan speed controller

I thought this would be appropriate given the current heatwave in parts of the world.

https://www.youtube.com/watch?v=Y4xtHcls-_w

It's a very minimalist design as cheap eBay products usually are.

The radio Hams might not be thrilled at the lack of RF noise suppression.
