If you can solder a little, you can make LED stars. The stars can be made 6 to 10 cm wide and use a 9 Volt battery as a pedestal.
If you want to easily change batteries, take a look at step 5. The star can be mounted on a 9 Volt battery clip...
No video playing? Have a look at it here...
So get your soldering iron, grab your LEDs, find some batteries and kick off the christmas decorating season.
If you're uncertain about your soldering skills: Start with making the star. It's easy. You can do it. Really. Trust me.
Still in doubt whether you should make the star or not? Here's the one decisive reason you were waiting for:
The first three Makers who post a picture of their self-made star in the comments get a 3 months Pro Membership gift code from me.
An additional one year Pro Membership gift code goes to the maker of the funniest / loveliest / greatest picture that involves a LED star :-)
december 17th: lmijacevic gets the first of three 3 Months Pro Membership codes!
Step 1: Stuff and tools
- 5 red leds, with a 5mm or 10 mm dome: up to you. The LEDs must be red to shine properly on a 9 Volt battery. I used LEDs with opaque domes as well as clear. Use what you think looks best.
- 9 Volt battery.
- 10 cm of sturdy solid copperwire.
- 1 blinking LED, 5 mm dome, red. I bought this one, it works on anything from 3 to 12 Volts.
- 4 "Low current" LEDs, 5 mm clear dome, red. These are LEDs that light up at very small currents. I bought these.
All parts for the star can easily be ordered at RadioShack, Mouser (if you live in he US), or Farnell or Conrad (Euro's, Aussies, rest of the world).
If you're new to electronics: buy a assortment of LEDs like this one.
The star costs about €1,60 / US $2,- if you can get a carbon-zinc battery for under €1,-
A blinking star costs about €2,90
Tools and other stuff needed:
- For a template: 5mm plywood or something similar.
- Soldering iron and solder
- Pliers or pincers
- Polymer clay or a third hand to fix parts for soldering
- Multimeter for debugging
