This is Tutorial #8 in the Selfie Ring Light Tutorial series.
If you have not yet completed Tutorial #7, you can find it here.
In this final tutorial, we finish assembly of the Selfie Ring Light, and check that it fits on your phone.
It’s not the end of the journey though – what else can you do once it’s all completed?
This is Tutorial #7 in the Selfie Ring Light Tutorial series.
This tutorial can be completed independently of Tutorials #1 to #6.
In this tutorial, we assemble and test the electronic components in your project box.
On completing these steps, you will have Bright Blinky Lights! …but you’ll still need a case for them.
The Selfie Ring Light is designed so the electronics can be built and tested first.
(The next tutorial covers the final install and assembly)
This is the electrical view of what we’re building; the Schematic or Wiring Diagram
We’ll refer back to it several times.
This article covers one method of attaching wires to a bare lithium-polymer battery pouch. This could also be done using a battery spot welder, clamping, or screwing.
Warning: Lithium Ion and Lithium Polymer batteries can catch on fire if shorted, punctured or overheated.
Be careful when soldering that the battery does not become hot.
Ensure you have an appropriate fire extinguisher nearby.
Step 1: Wire Prep
Before you solder the terminals, plan your wiring.
Where should the battery wires exit the battery? In what direction will they go, and how far? (A scale printout of the layout may help)
Strip and tin the wire ends.
Each bare end should be slightly shorter than the battery tab’s width.
