The first project of the class is to make a DIY flashlight.
Flashlight comes in many forms, as soon as I figured out the circuit connection(see below) , I started to search around on closure.
There are many options I came across, some of them are innovative and cute.
Because I want to practice the tools demoed in first class, also for the sake of $200 lab fee, I decided to use polypropylene storage box as a closure, with batteries and circuit inside and a switch and LEDs on the surface.
So, the tools and parts used are:
4 AA batteries (in Battery holder)
3 Super Bright LED (10mm)
1 rocker switch.
The tricky part is to solder everything together, and I forgot how much I hate soldering.
The end product looks like this:

When the switch is on —
I’d love to see a final picture of the project.
