DIY talk

Would love to hear a sample of the mic

 

He has a soundcloud where he recorded some ambient sounds but no dialogue. As soon as I get an interface I’ll post a sample

 

Looking for someone with the skills, inclination and interest in building an autoformer preamp with balanced and SE inputs and outputs and a remote, sound like a fun project to anyone?

Is an autoformer really balanced? I feel like TVC is the only way to really go balanced.

That being said there’s still advantages using XLR differential input over RCA

 

I decided to buy the iCon 4 pro from england so do not need help with a build

One leg of the autoformer is grounded and there's no isolation.

In theory you could float it and have it "balanced", but it still wouldn't be isolated.

 

So I recently became a first time home owner. There’s a shed in back that the previous owner used as a dedicated wood shop and it rules. They left behind this kickass french work bench and the electrical wiring even has 3-phase power if I ever want professional equipment with a brushless motor



I might start a more dedicated thread because I got a lot of ideas for projects.

I also want to setup a place for electronics, but it’s probably not a good idea to do it in the same space where there’s going to be a lot of sawdust.

 

This is true freedom.

 

Dim the lights a bit, add some halloween decor, that's a scene right out of a horror movie...

 

Acoustically speaking, it's very well insulated...

 

Merchant: so what kind of absorption panels are you looking to buy today?
Cspirou: I'm not sure, what frequency range does human screaming fall into?
Merchant: What?
Cspirou: What?
Merchant: ...
Cspirou: uhhh... human feelings. Yeah, lots of... loud feelings.

 

I should probably make this a thread i its own right but at this point it is merely repeating what others have done as proof of principle.

I stumbled on a maker thread where the person was using PCB fab houses to print flexible PCBs for a planar driver and it got me thinking that this might work for a fun headphone project :



so i went about and ordered up some flexible PCBs and printed frames to hold the magnets









Once I have them assembled, I will measure them and see what can be done.

Flexible PCBs???? I had no idea such a thing existed. I guess I'm now making planars as well lmao.

 

I’ve seen flex PCBs before but never thought about them for a planar. I assumed they could only be done with really light films, but PCB tech had advanced in ways I wasn’t aware of

 

it might be a little heavy but only one way to find out - if you go back to the start with the original vintage planars - they had about the same thickness films. Talking original Mylar Fostex or Wharfedale ID1 etc - no comparison to the "sneeze and tear me" modern planars ..dB

( and it cost me < $20 for 5 PCBs shipped = high fun to cost ratio )

 

If it turns out to be too heavy for full range - oportunity to mess around with 2-way design.
To my thought planar is dumb for highs anyways. Great for bass (in headphone) and mids.

 

Why so?

 

I do wonder why multiple drivers are common for speakers and IEMs but never really took off for full size headphones. I guess it’s at a sweet-spot for both bass and highs?
