Creating a leather strap with a simple LED light and a metal encasement is not a simple task especially when you want to make it elegant and simple by embedding all the electronics perfectly.This week I am taking the role of the CTO in order to research about other alternatives to produce a high-fi prototype for Raiden.
The LED light that we bought from spark fun electronics a couple of weeks ago is powered by a 12V battery.The only batteries that come in that voltage are super bulky and will look very ugly on the leather strip.
I decided to experiment with other type of LED called 4 Warm White 5050 SMD LED that I preordered from super bright leds.

What is great about this type of LED is that you could use a 3V battery that comes in a circular cell shape that could be easily embedded into the leather strap.The only problem is that the intensity of the light is very subtle. They are 19 Lumins only.
It would be possible to use this if we could create something called a parallel circuit where we could place 3 LEDs lights, add 3 batteries that would be connected to 3 battery holders. Since 3V batteries are super small, they would perfectly fit into the leather strap.
The light costs 0.65$ each
The batteries costs 0.77$ each
The battery holder costs 2$ each

I found out that these batteries were very practical since they are very popular on alibaba.com which is a great manufacturer resource.I tried to see if anyone was selling this type of light that was already made but couldn’t find anything online. They sell these type of lamps where 20 or more of these LED lights are embedded into the lamp.I decided to go to a store called Canal lighting and parts on Canal Street and found out that they sell these LEDs ribbon strip lights.

The great thing about this type of lights is that they are already made: soldered and attached to a plastic 3M strip. Daniela and I will be working together this week to combine the leather straps with these LED strips in order to make a high-fi prototype for Raiden.
