Step #1: Test the LEDPrevNext
- Identify the negative (–) and positive (+) leads of the LED. The negative is usually the shorter of the 2 legs, but here's how to be sure: Slip the coin cell battery between the leads. If it doesn't light, flip it over. When it lights, the negative lead is the one touching the negative (–) side of the battery.
- Put a kink in the negative lead if necessary, so you can find it later.
Step #3: Solder the LEDPrevNext
Solder the negative lead from the LED to the negative (–) lead from the battery holder.
Step #4: Solder the tilt switchPrevNext
- Solder one leg of the tilt switch to the positive (+) lead of the battery holder and the other leg to the positive lead of the LED. Depending on the switch you're using, this may require some bending.
- You can use a helping hands tool but I just use a bit of kneaded-rubber eraser to hold the components while I solder.
- Clip off any excess leads.
Step #5: Add the batteryPrevNext
Insert the battery in its holder, and flip the lamp assembly upside down to test the on-off action of your LED and tilt switch.
Step #7: Two ways of makingPrevNext
NOTE: There are 2 ways of mounting this type of tilt switch: you can simply solder the leads, as in the example on the right, or you can strip part of the switch's coating and also solder the switch body to the battery lead for extra strength, as in the example on the left.
Step #8: Use your draailampjePrevNext
Next to the bed, at the campsite, in the rain — this handy lamp has many uses. And the light will remain bright for 5 days and nights of continuous use — just replace the inexpensive battery when it starts to dim.
Step #9: Going furtherPrevNext
- Why not upgrade your draailampje? Try adding a slow-fading multicolor LED, or making it solar powered or rechargeable.
