Hey All- A friend of mine is doing a booth at interbike. For those of you unfamiliar, it is a very big bicycle industry trade show and exhibition.
He wants to have a concept bike with a portable turntable and speakers mounted to a bike and powered with a battery.
Obviously this is something fun for a show, not meant to be actually ridden around while a record is spinning.
My question is this: What would be the simplest way to implement this? DC driven turntable with battery with battery powered phono stage and powered speakers? Does not have to be the most impressive, amazing sounding audio, but should sound reasonable. Let's try to keep the budget down, but this is a secondary concern at this point.
Thanks!

Hi,
No simple way of doing it, AFAIK DC powered turntables don't exist. *
However DC servo turntables do exist, and it may be possible if
you can find one that uses a single 12 to 15V rail for circuitry,
and then bypass the mains transformer and rectifiers.
rgds, sreten.
* They may have as part of a rack system all powered from
the main amplifier, generally the power for them was 12V DC.

Some Sansui turntables came with 15V external DC adapter. I had one (DA-P500) of which I kept the motor; the plastic plinth and tonearm were discarded. With extreme safety precaution wouldn't a mini generator (Inverter+battery) be an ideal solution ? A Turntable and small active digital monitor speakers with digital amplifiers would also be neat and tidy. Isn't it ?
Regards.

I'm sure there were portable battery powered record players. Perhaps with a proper arm and cartridge they wouldn't sound awful. Or, use an open-loop DC motor to turn a belt-drive platter. Like from a cassette player.
A standard vinyl player and a 300W sinewave inverter with a car battery does the trick. If you don't have a turntable already - get one with a built-in riaa, so you save on the number of boxes. Use active speakers with a volume pot.
Much better: Pro-Ject Maia DS amp, standard vinyl player, standard speakers and the same battery/inverter.
