Where's the THD/Distortion test? 😭or a short audio demo? Phil's Lab has done a more complicated version of this I believe, demonstrating paralleling SMD parts of the 5532 to get a much bigger output power, and hopefully sometimes cutting down distortion too.
I do stuff but it's all on breadboards and 90% of it is Arduino nano software and mostly has to do with blinking, flashing and pulsing LEDs and making weird sound effects with VCOs and stuff. (The Arduino nano is permanently stuck on one of my breadboards. Once you push all those header pins into the breadboard there is basically no removing it :-)
Are the output caps big enough (for a quality headphone amp)? Using 10uF together with the usual 32 Ohm headphones i would expect almost no bass at all... Maybe with high impedance "cans" - but they are kind of rare today...
@@andymouse it was a great video Mr squeak but I was just agreeing with the other commentator that he was correct but I should have added then when the impedance of the output cap matches that of the headphone we can say that the output power has dropped by -3dB. impedance of the cap cand be found by impedance Xc =1/(2 x PI x F x C) or by transposing the formula the frequency where the cap impedance =32 ohms frequency = 1/(2 x PI x C x Xc).
@@andymouse I was already on a bit of a cap roll having commented about them on a previous video. But IMSAI Guy is a bit like Mr kipling but video's and not cakes. UK joke.

I'd love to get into the garage but that's where the spiders live.
Yikes 😬
does it work?
Magic Oven! Count to three and bam! you have a fully populated PCB just like that.
You've got to envy folk who have an oven!, have to do mine the hard way.😂
I'd like to have seen you power it up.

Finally! I can turn a headphone signal into a... headphone signal. :/

looks like the -3dB point would be around 500Hz, but then I'm just thinking out loud.
It's not a quality headphone amp and it was never meant to be, it's a fun educational project and probably sounds ok to boot !

@@TheEmbeddedHobbyist Howdy TEH !! loads of mafermatiks Squeak! yeah, I think the other guy was taking it a bit too seriously that's all :)
