Introduction: Handy Outdoor Light Using LiPo Battery

For the outdoors, I wanted a portable light that was small to transport, and that can easily be adjusted for different uses. After looking around for stands, I came across an inexpensive microphone stand.

Having a stand, I needed to fit it with a light and battery.

A light that works well, is a standard 12V LED downlighter bulb. The amount of light is well suited for all types of outdoor activities, including rigging up a fishing line with hooks etc.

As I have a lot of 11.1V 2200mA LiPo batteries, I decided that the light will be fitted with such batttery. Tests with a 2 watt LED light showed that the light can be on for at least 12 hours before the battery runs flat.

Step 1: Modifying the Stand

The arm holding the microphone is hollow, and ideal to run wires through it.

This stand did not come with a microphone holder, only a screw where the holder is attached to. First, I removed the silver mic holder screw. Secondly, I removed the locknut used to lock the rotating movement.

Step 2: Making a Battery Holder

I used 50mm PVC pipe, the same as used on pools. I cut a piece of pipe, about 30mm longer than the length of the battery I will be using.

On one of the endcaps, I drilled a 16mm hole to attach it to the microphone arm. I also drilled a hole for a small toggle switch.

After painting, I mounted the endcap to the microphone arm, attaching it with the locknut I removed earlier.

Step 3: Wiring Up

On the other side of the microphone arm, I drilled a 5mm hole for the wire. I ran a piece of twin flex wire through the microphone arm. To ensure one does not pull the wiring from the battery holder, I made a knot in the wire where it will exit the arm. I removed the wires from the light socket, and soldered the socket on to the wire coming out of the microphone arm.

In the battery compartment, I soldered on the toggle switch, as well as a Deans connector for the battery.

Step 4: Installing the Battery

Using some glue, mount the 50mm pipe to the endcap mounted on the microphone arm. I inserted a round piece of sponge into the holder, to prevent the battery touching the on/off switch.

The battery slides into the battery holder, and is kept in place by the second endcap.

Step 5: Battery Protection

To ensure I do not drain the battery, I fitted a battery monitor into the battery holder as well. Have a look at this Instructable:

Now this this is clever. I use an old IV stand to hold fuel bottles, carb sync tools, etc, for working on motorcycles. I think I'll add an arm to it for extra lighting.
