Clear Silicone Molding

Hello all,

I am looking for advice on how to cast parts with clear silicone. I need to make some light guides that people can jump on. Imagine a 2" x 2" square that will have RGB LEDs moulded into it that a grown man could jump up and down on. What I need is advice on how to do this:

1) Can someone suggest how to best make moulds that can have silicone cast into them? Should I make the moulds out of acrylic? What type of mould release should I use?

Dual Cell Lipo Charging IC

Hey guys,

Can anyone suggest an IC that could be used to charge dual cell Lipo batteries (7.4V) with cell balancing? Ideally the IC would be powerful enough that it could charge even if the system is under a light load. I am looking for something similar to
