Long exposure night photography can be a fun pass-time especially on a cool summer evening.
"Light painting" can make things even more fun. If you've looked into light painting you've no doubt seen Orb's, spherical mystery lights....Orb photos are created by spinning bright LED lights.
This Instructable will show you an easy way to make a low cost orb creator and give basic instructions on how you can create your own mysterious Orb Photos
You don't need an expensive camera to take shots like these. Just one that can keep the lens open for 30 seconds or so.
A good option is an inexpensive Canon brand point and shoot and free CHDK (Canon Hack Development Kit) software see http://chdk.wikia.com/wiki/CHDK . See the website for models supported.
Here is a flickr pool that shows more examples of Light Painting Orbs
Step 1: What's needed
- Power source - i used a 6V 4 AA battery holder
- Wire (approx 3ft) - I happened to have a power cord from an old swag lamp, worked great and featured an inline switch.
You could use old speaker wire or bell wire taped together.
- LED bulbs (3) - I pulled the 3 LEDs from some old Finger LEDs with burned out batteries
Any standard LEDs will work fine.
- Resistor (1) - it's a good idea to use a resistor to ensure the LED bulbs don't overload and burn out. I used a 100.00 ohm 5 Band resistor (Brown Black Black Black Brown)
Depending on how many LEDs and which type, you can validate the correct resistor here
- Electrical Tape - prevents shorting
- Wire Stripper
- Weight - something to weigh down the LEDs while spinning, old AA batteries would work fine, improvise :-)
- Soldering gun and solder
- Switch (optional) - you'll find it's easier to create orbs if you can turn on and off the lights while getting into position, but a switch is optional, you can either hide the lights or disconnect the battery pack.
- Breadboard (optional) - handy for testing things before soldering, you'll need some jumper wire as well.
