I know you are looking for a home brew design but we use one at Field Day.
$18 from Amazon, $25 after tax and shipping. Hard to build one at
that cost

Does anyone have some design to home brew a multiple headphone ummm
Mixer? Ya know plug into a headphone jack and be able to have multiple
headphones plugged in.
I'm thinking say two to three or so headphone jacks, and a final output
for a speaker, and able to have all independent volume controls. and
keep the various impedances as needed.
Anyone have a good home brew design?
