[AccessD] OT: portable headphone amps.

Hi John:

I have a good friend who is still a electronics geek. I have been working on
his website for a while (but he keeps changing things so often that it just
never gets finished and it is low priority...non paying gig...but it will be
finished by the end of February).

Here is the test site:
http://electrichubcap.creativesystemdesigns.com/

You might find some of the stuff he builds interesting.

Jim

As you have probably gathered, I have many interests, including DIY various
things.  I have built a 
DIY CMOY headphone amp, see discussion here:

http://nwavguy.blogspot.com/2011/07/cmoy-with-gain.html

which I ended up giving away to my brother-in-law who is mostly deaf.

Anyway, I ran across an interesting blog for a DIY headphone amp.

http://nwavguy.blogspot.com/2011/07/o2-headphone-amp.html

If you read that you will find links to other blog pages discussing many
details of the design and 
electronics.  I started my career in electronics back in the 70s and loved
op amps in particular. 
It has been a loooong while since I really studied electronics but it still
fascinates me.

Enjoy.
