With any luck, you’re now the proud parent of your Watch a video of the Pixelmusic 3000 in

way to enclosed-perf-board heaven. They both work.
The PM3K sends a composite NTSC signal to the
TV over the yellow RCA cable. Older sets, like the
beauty pictured below, may not have a composite in
(ours didn’t even have a coaxial in). Not to fear; just
head down to any electronics store and get an RF
modulator, which will convert the composite signal
to 2-wire VHF antenna input on channel 3 or 4.
HOW TO USE
There’s a sweet spot for visualizations. Too little
volume and the shapes, patterns, and colors won’t
change very much. Too much volume and things
may change too frequently or be too big. Try playing
with the input volume to find just the right level.
You may also want to adjust the ADC’s trimpot to
make big tweaks once or twice.
MODS AND ROCKERS
The goal of this project is to create a retro rave in
your living room, but the PM3K is portable too, so
you can bring it to your friends’ parties and impress
all the right people. It works with iPods, CD players,
or anything else with a mini headphone output jack,
and it’s just as fun with modern music and audio
books as it is with classic album-oriented rock.
There’s plenty of room to mod your PM3K. The
code is yours to tweak and revise, and it’s fun trying
to create programs to run with the limited RAM and
color budget that the Propeller allots. You might
want to try adding some pots and switches; there
are open slots on the ADC and open pins on the
Prop. Or maybe an onboard mic? Whatever you do,
be in touch and let us know. We’ll drive our Nova
over and bring our Freedom Rock playlist.
