Thought I’d seen it all. Came across this scanning a thread on another forum.

Audiophoolery at its finest!

I can't imagine how quickly these dry up. They probably need to be replaced every year.

The whole site is gold.

The thing I find quite sad is that the individual in question actually has some pretty good skills and engineering ability looking at some of the other projects and creations.

But he's clearly as mad as a box of frogs at the same time.

Some more gold, or quartz: https://www.dhtrob.com/projecten/quartz_and_audio.php

"They will sound much better than before!"
Yes, I'm sure that's true -- when you knock them against each other as a percussion instrument, for example.

I appreciate the arts and crafts, but dude.....

Holy f*ck...

The insanity of it...

And yet, someone let them have sharp objects to play with...

If he's worried about mechanical damping (presumably the 'justification' for the wood and beeswax) then why doesn't he just put the whole capacitor in? What's the point of removing the Aluminium can when it's full of Aluminium foil anyway.

Maybe he wants the winding to be 'relaxed' rather than confined.

Someone should suggest to him making wooden brain.

CJay · « **Reply #8 on:** June 29, 2018, 12:16:59 pm »

I think he may already have one and found his inspiration there...

He was doing so well, and then he stuffed it up by using synthetic PVA glue to close the lid. Anybody who knows anything knows that you ought to use hide glue for this kind of application, just as hide glue was used by all the great violin makers. For preference, Rabbit hide glue.

Audiophoolery or how to build the strangest incendiary device to burn dowm your house.

Not to mention that a wooden case certainly doesn't help with dried out capacitors.

With no vent, doesn't this wooden capacitor risk becoming a bomb or at least a gun with the glued on cap firing off?

I am doing to do this, but with quartz. We all know quartz has superior acoustic qualities over wood.

That's it, we must defeat them with their own stupidity.

Have them all use wax paper caps and crank up humidifiers, that will soon cause lots of shorts and ruin the bullshittery once and for all!

EDIT: Yes, they must be USED wax-paper caps, to ensure more rapid equipment destruction.

They wouldn’t show up on a low voltage tester as well.

Psss feel the burn Carlson.

Someone kill me now! Right now! I don't want to breathe another breath!

I need an asteroid the size of the KT extinction event to land on my house.
Or at minimum, me sitting on the tsar bomb while it detonates.
Our sun mysteriously going supernova would be acceptable too.
A change in equilibrium of the universal physical laws and constants instantly erasing the entire universe would just about be acceptable as well...

From that site

Now we measure the height of the elctrolyt. This is done to cut to size a piece of ricepaper which protects the electrolyt against the hot beeswax. Ricepaper has best tonal qualities (no joke!).

Should laugh or cry ?

Brumby · « **Reply #18 on:** June 30, 2018, 04:40:07 am »

That timber coffin for the capacitor's guts will give it a significantly larger footprint. High probability this will be a challenge to refit to a typical PCB layout. Also, will the leads be long enough?

I hate to think how the audio quality will suffer if leads are extended. Oh, the horror!

Cyberdragon · « **Reply #19 on:** June 30, 2018, 04:14:57 pm »

Oh noes!

There must now be one made in Lego!

What is sad is, that is actually not very uncommon in the audio world.
Very highly skilled and smart engineers starting to believe in fairy tales.
It's weird, kind of losing sight of all other things people have learned at school.

Hey! Don't knock it 'till you've tried it! I built some and they really do sound great. Trust me... I'm on the internet and you all KNOW that everything on the internet is absolutely true.!!!! I can build you custom wood caps for the piddly sum of 1 bitcoin each.

But, for maximum performance from your system, you must connect the ground to a massive metal structure. I currently have a really lovely iron tower in Paris, France. Also a wonderful suspension bridge in San Francisco. And the ultimate copper lady statue in New York harbor. These are a bit pricey, but WOW! You won't believe the sound.

Brumby · « **Reply #22 on:** July 01, 2018, 02:38:03 am »

I've seen pictures of that copper lady. She needs a good polish!

bitseeker · « **Reply #23 on:** July 01, 2018, 02:39:14 am »

Ooh, natural materials. So it makes your electronics more green. Better for the environment! And since it's high-quality wood and lacquered, it must sound especially great when you play classical music through it.

PFFT! I bake my capacitors in the oven for 30 minutes before sealing them in their balsa wood cases with mahogany stain. They produce loud and vibrant tones.

EDIT: They have an excellent affinity for the note B₂...
