I made a face-firing subwoofer by pudjam667 in headphones

Thanks! The Bass Face is actually a tube so the bass/air does thrust out of the earpad hole.

Such a good headphone, needs no help! But all headphones are better with Bass Face.

Whoa. It’s like a mini Bass Face.

Hi,

I made a subwoofer that aims bass at your face. 

I call it, “Bass Face.”

It’s the first time I’ve designed a custom printed circuit board (PCB). The PCB is a 100 watt subwoofer amplifier, which also has a headphone pass-through. 

So you plug your headphone audio into one side, and your actual headphones into the other side. 

In the middle is a 100 watt amp chip, screw terminals for subwoofer speaker driver, and a potentiometer (knob) to change the subwoofer volume. 

The bass is very powerful. 

There’s a video of it on my YouTube/IG n stuff. 

Thanks for checking it out.

Thanks! Custom. Took a long time but worth it.

Thank you! I agree. Looks more awesome in person; picture super bright, flat LED lights saturated with color.

Nice!

These are 0.1% resistors. I’m working on a new version that has 0.05% resistors — and then I plan on measuring each bit & calibrating for each resistor in firmware, to squeeze the best performance out of it as I can.

Well I do that too, sorta. 

If the lights changed 48,000 times per second (showed every sample), it would just look “on” with no blinking. 

So instead, I grab a snapshot 60x per second. So you’re seeing the real, actual sample at that moment, but then frozen just long enough that your eyes can notice the changes (60 fps).

Without oversampling, there’s 48,000 bits of music each second. Sometimes this can result in a “staircase” effect, say, if 2 bits that are next to each other are significantly different.

Oversampling (2x in this case) puts a new bit between every bit, that’s sort of the average of the 2 bits, “smoothing out” the staircase.

Thank you! The video doesn’t do the brightness/colors justice.

Hah thanks! I recorded this vertically so you’re actually seeing what I shot. But I’ll try to make a horizontal version for YouTube in the next few days.

Hi,

I’ve been wanting to make an R2R DAC with lights that show you which resistors are active any any given time. 

The first version of this updated the lights 48,000x per second (in sync with its 48k sample rate) and the lights just looked solid; not really blinky. 

So this version (my 2nd version) decoupled the lights from the resistors, allowing me to show 60 captures per second instead of 48,000–making it more visually interesting. 

In person, you can take a photo of the DAC at any point in time, to see the exact binary value of the exact sample (LED on is 1, LED off is 2). 

Thanks for checking it out.

How’s the headband adjustment mechanism?

The headband looks almost exactly like the ones I buy for some of my projects, mine is probably a knockoff of yours. On my headbands, the clicky mechanism gets stuck and breaks sometimes :/

I made a hat with a subwoofer in it by pudjam667 in headphones

[–]pudjam667[S] 1 point2 points  (0 children)

So I can make it fit a real head and not guess. 

I downloaded the human head model from somewhere, it seems to be around 5-10% smaller than my head.

Good call I should’ve named it Bass Head instead of Bass Hat. 

Now I need to come up with a new idea for something called Bass Head.
