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?

Small Parts Store Canada

Hey guys,

Does anyone know of a good small hardware store that is in Canada/will ship to Canada and not charge an arm and a leg for shipping?

I am trying to find something like this;http://www.smallparts.com/

Sadly this place charges an import fee and shipping that makes buying unreasonable for us Canadians.

Begginings of a Quadracopter

Hello LMR!

I plan to design a quadracopter in the next year with FPV. The first step in this endeavor is to build a quad using off the shelf parts. I am asking for feedback from you guys before I purchase parts. Any store suggestions or past experiences are greatly appreciated! My biggest problem is finding a good TX/RX system. I need one that will last me for a while but not cost more than $120, can anyone suggest something? Right now I plan to purchase;

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
the MAX 1555 IC (http://www.sparkfun.com/products/674) but for multiple cells. My google search has been fruitless - I must be using the wrong keywords. Thanks for any help!

Writing to COM port with Windows 6.1 Mobile

Does anyone out there have experience writing to a WIndows Mobile COM port? I have an Arduino with a bluetooth module attached to it. My Windows Mobile 6.1 phone is able to detect the bluetooth broadcast and connect to it, however I do not know how to write commands to a COM port in windows 6.1. If anyone could point me to a program, method or .cab file that would help me do this I would really appreciate it.

Phone: Sony Ercisson Xperia X1, running Windows Mobile 6.1
Bluetooth: BC417143 B-IRN-E4, this is a cheap class 2 bluetooth module from China.
