This isn't the only way to do it.
It's probably not the best way to do it.
But it's how I did it.

[@MrWallyGattor]

G'Day Mate! love your videos down here, my wife blames you for all the little packets that come in the mail

[@pileofstuff]

Sorry? Or you're welcome.

[@onecircuit-as]

One of the three Australians watching would like to know how those spinning wire thingies work - genius! 👍😀

[@RoyAntaw]

plus another one from the damp Blue Mountains west of Sydney.

[@Palmit_]

Slip ring. If you had a thick circular pancake of non-conductive material. slice it half along it's side. now you have two pancakes. Pancake 1 (lower). draw 6 different sized circles (that don't touch). coat each circle in copper. so you now have a cunductive track. each track has a wire that goes off to it's connection. on pancake 2 (upper), have 6 springy contacts, spaced the same distance apart as the rings on pancake 1. connecting incoming wires to each of those contacts. now we have the two parts connected and both can spin freely. (obviously the construction needs a non rotating bushing in the center and 'click together' fitment around the outside. done :)

[@michaelmagnani3463]

I'm the third 😂😂😂

[@onecircuit-as]

@@Palmit_ Mmmmm...pancakes! 😋

[@TheUnofficialMaker]

slip rings, use brushes

[@colintett6872]

I’m sure there’s more than three of us watching in Australia… You’re a star down under!

[@pileofstuff]

You'll make me blush (or maybe that's the alcohol...)

[@henrybest4057]

Those sliprings would be ideal for powering the track on a model railway/railroad turntable.

[@maebeans]

"for the 3 australians that are watching," oh hey, that's me

[@MrTheog1989]

I'm one of those Australians that are watching! Woohoo!

[@ericblenner-hassett3945]

You could try putting an ESP32 device in the faraday pouch to test how well it blocks it from connecting to your network, have it flash an LED when it can't connect.

[@AnotherMaker]

I love those spinning wire bushing things. I need to pick some of those up. I switched my high power office and garage lights to those fan style things from Costco. I think 2 for $20 or $25 us. I'm really pleased with them. I have low power lights also, but when things get real, it's nice to be able to flick those things on.

[@TheUnofficialMaker]

LOL Called slip rings.

[@Clell65619]

A word of warning for those garage lights. When they first showed up for sale, I grabbed a couple of the cheap ones, and boy howdy are they bright. They also swamped the garage door opener receiver, so if the lights were on, I couldn't open or close the door, even if I was in the garage. If you use a garage door opener, check for interference.

[@TheUnofficialMaker]

had no problem with my GDO

[@BrianBoniMakes]

I used to service scientific equipment and a 6 pole slip ring cost over $1,000 dollars. The ones that used carbon brushes were serviceable and required lubrication with silver grease, the mercury ones were sealed. Mostly they were used for thermocouples but the odd time 48v, nothing more.

[@TheUnofficialMaker]

WE USED BIG ones in a husky inj molding machine that had a 4 face mold to make preforms for water bottles, eliminated a side entry robot

[@pileofstuff]

I'll be interested to test these. After I figure out a test rig.

[@SidneyCritic]

I'm going-to glue that mesh to the side of my head - lol -.

[@fredflintstone1]

yea!!! another Monday 🙂

[@pault6533]

I bought both fan lights in a smaller version. The fan lights last well enough when they are cool white. I prefer warm white, and ordered some of both. All the warm white ones developed black dots in the LEDs and within weeks stopped working because the LED's are in series. Evidently they overdrive the warm ones to produce the same amount of lumens as the cool white, and it's too much. All my cool white ones still work. Very cheap inside. When you open it you may find the wire connecting to the threaded part of the socket has come loose. The electrical connection is a crimp not a solder, nothing special just the standard crimp of the threaded metal onto the plastic with that wire stuck ibetween.

[@tinygriffy]

These slip ring contacts are probably useful when building one of these rotating holographic led displays .. so you don't have to spin the battery.. dunno if they can handle the 800 kHz signal for the leds .. I think bigclive has a disassembly video on those.

[@ataasgari]

11:37 ECO "FIRENDLY"!

My audience is expanding!

[@andrewpaton2325]

I’m a keen subscriber from Australia

[@adam850]

Throw a RFID card in the pouch and see how well it blocks reading

[@barneybotha2437]

Also try a car key/remote

[@Palmit_]

I bet its something really small and silly to fix the light. can't wait to find out! :)

[@Stuart-AJC]

I've got a couple of those 'Faraday' pouches, and they don't work. I keep car keys in them, and even when they are in them, the car still opens when I go near it. YMMV though

[@FurbleFawks]

I've mostly seen people use those for cars that can be started by just having the keys with you and have keyless entry as well. They seem to be effective enough to stop the 433mhz most keys use if they're made properly

[@TheUnofficialMaker]

mine works

[@davebrooks993]

I thought the faraday cage only works if it’s grounded?

[@iowahank1]

3 Leaf written when the picture shows 4 on the light. Typical ad... Shipping it back will cost more than the price of it so I see a teardown/repair in its future.

[@fiskurtjorn]

5:55 Went to the comments to say what you just said...

[@jamesdk5417]

Does your analytics really show only 3 of us Aussies?

[@user.A9]

I'd like to see you test the "gold" connectors to see if they are really gold.

[@pileofstuff]

That's a bit more of a chemistry project than I have the skills for .

[@johncoops6897]

Why do you keep spamming this. Nobody needs your long explanation, and the slip rings he showed don't even have that configuration.

[@Palmit_]

spamming. ?? i apologise. it was cos the reply i gave, was to a comment. so i commented on main thread as well so as to help any others with same question. @@johncoops6897 .. can you explain another config please. i'm interested also

[@midinotes]

pretty sure that second fan light had a recessed tip on the screw fitting so didn't make contact. In the video the tip of the screw fitting looks pushed in.

[@pileofstuff]

Stay tuned fo the repair video coming soon.

[@jamess1787]

Do you have a store front? If not, you should consider it

[@pileofstuff]

I don't want to get into that game. But I do get a small (very small) commission if anyone uses any of the links to Ebay, Aliexpress or Banggood

[@Steve_Coates]

Trying to visualise a monitor spinning at 250rpm, POV holography perhaps?

[@pileofstuff]

No idea either. Maybe short bursts of rotation on a stage light? Bu that would want a lot more current than the tiny wires should handle.

[@TheUnofficialMaker]

used them for prox switch connections

[@Steve_Coates]

@@pileofstuff You could use it for mapping with a TOF sensor or ultrasound I suppose although I'd be dubious about the noise from the slip ring contacts with Aliexpress cheapies.

[@frankowalker4662]

You may as well just turn your phone off instead of putting it in that bag. You can't use it in the bag, as you cant see the screen. LOL Also a word of warning, sometimes when products like this say it's anti-radiation, they can have quite high levels of radiation in them.

[@pileofstuff]

That's what I was thinking. Turn it of or set it to "airplane mode". At minimum It's a cheap source of metal mesh fabric. Maybe I can use it for shielding on a project.

[@njsurf1973]

I believe some of the tinfoil hats believe that even with the phone off, "they" can still track your phone if it isn't in a faraday cage. I believe they can track me no matter what, so I don't care lol

[@Steve_Coates]

Blackberrys couldn't be fully turned off, I discovered that when I got off a long haul flight and discovered I had received around 30 texts "Welcome to Vodafone Abu Dhabi" etc. despite the phone being turned "off".

[@Okurka.]

Those fan lights were sold as Warm White yet they sent you 6500K Cold White. Ask a refund for both lights.

[@DustinWatts]

There is a lamp and one is totally deformed. Conform description. So what are you complaining about?

[@sparkyprojects]

I would be careful about putting a phone in the bag, specially if it has exposed antenna strips around the edge The only thing i can think of for putting your phone in is if you still want the alarm to wake you Or is it that a phone is never truly turned off (conspiracy theory anyone ? )

[@TheUnofficialMaker]

the ones i see are used to keep your car keys safe so thiefs can't clone them

[@fredflintstone1]

Hmm instead of the case just wrap your phone in silver foil???

[@henrybest4057]

Yep. That'll fool all dem govmint spice!!!

[@DeathbyKillerBong]

anything anti-radiation needs to be tested for thorium oxide contamination, you have a geiger counter right?

[@pileofstuff]

I don't. Probably should try to find an affordable one.

[@Irilia_neko]

My phone is way to big for this thing, also, airplane mode 🤔😜
