My mum has asked me to help her with a christmas parade float.
She wants people walking along side holding long bamboo poles with flashing led tubing to represent data transmitting along a phone line.
any ideas?
LEDs can run off batteries just fine, depends on how bright you want them and how long you expect them to last. Most LEDs may not be very visible during the day and the bright ones usually have a focused beam.
Flashing a 12V blub will be brighter and easy to build, you can even use a car flashing relay to simplify things.
Can you draw a sketch of what you want to do? Bamboo poles with LED tubeing? Like rope lights? Does this go on the pole or between 2 people with poles? I don't quite follow.
Ready made rope lights will most likely need AC line voltage to light. No going to work with batterys.
The first way is to attach 10 car batteries to each person back
And the other... correct me if I'm wrong (english-spanish-english issue), is a float parade a group of people with costumes, saying hello, on top of a adorned vehicle?
In that case, a power inverter could be connected to the vehicle electrical system, and the 110V output distributed to each of the crew via hidden wire.
I hope they use good isulation, and not doing it with rain!
