The "Jingles" Box
One of the first questions most of the British people ask us
when they hear about the ICV is "Do you have the jingles
working?" - What we in the USA call the "music box".
Well, our ICV didn't come with a jingles machine - I
originally didn't think this was a big deal - I figured I'd get
on Ebay and just pick one up - well, it turns out that the damn
things are like "gold dust". We looked for quite a while to find
one that was the right vintage and was true to the English tunes
and so forth - the 1971 technology was not too advanced (as you
might imagine) - usually a pretty worn out cassette tape that
looped. These machines were incredibly expensive.
So, we went to plan "B" - find the tunes in MP3 format,
download them to our iPod and play them over the loudspeaker -
searching and searching on Google yielded exactly ZERO tunes for
ice cream trucks. Lots of music by bands called "Ice Cream
Heads" or "Ice Creamers" or whatever - but no music box type
tunes.
So, we went to plan "C" - buy one in the states. Turned out
that was easier said than done. There are a few different brands
here and there - but very hard to find. One day, John found one
of the "real deal" Nichols Electronics music boxes on Ebay. I
looked it over and it was pretty beat up - the knobs were busted
off but the guy claimed it worked - and you could adjust the
volume with a needle nosed pliers - so, I setup my
Auction Sniper to
stuff a bid in at the last second - and after spending about $93
on the thing (including shipping) - it arrived - with a
loudspeaker!!
Here is what it looked like when it came:

The box itself is about 4 inches wide by 2 inches high - you
can see that it has 16 tunes with 2 channels - total of 32 tunes
inside of it. Of course both the volume AND the tune knobs are
broken off - I emailed the seller and said "how did you change
the tune?" - he replied and said "I took it apart but you only
need one tune and the one it was set to is the perfect one for
ice cream trucks".
So, of course I took it apart to see what was inside -

Just a little solid state circuit board, with one 28 pin chip
on it - and a little audio amplifier. Pretty low tech in
comparison to an MP3 player.
I spent a few hours taking it apart, drilling out the
existing switches/volume knobs, then fabricated some little
knob/handles from #10 copper wire. Put the new handles into the
drilled holes with some JB Weld epoxy - and presto! the thing
works like a champ - here are a couple shots - We're ready to
mount that baby and make some noise - wanna hear a
"jingle"? - click here
