Sure, and I imagine I could design one myself easily enough - I know
_that_ much about electronics.
But I don't have any suitable optoisolators on hand (I found only one,
and its output device was a mains-voltage triac), and the hassle factor
of obtaining some was enough to outweigh the extra dollars the pre-made
adapter cost me.
Besides, by the time you add in mounting and housing, the cost for the
homebrew has probably at least doubled, in money and time both.
(Granted, its hack value would have been significantly higher that way.)

I was thinking a simple current to voltage adaptor, maybe 2 resistors
and a transistor that worked and somebody had actually built. I'm sure I
have some optoisolators, and I've seen the stuff on the net.
I was even thinking about a one resistor e-i converter. I've got 3 days
to play with it, I might
end up building the full monty if I can sort through all the junk and
find the parts.

[...joystick port MIDI converter...] Mine cost me CAD
34.45, TTC,
around the middle of last August.
Hacking together a very simple circuit with an opto-isolator, a few
resistors, diodes, etc. costs a lot less. There are several circuits
available on the 'net.
