This tipster shows how a used CR2 battery from an LC-A Instant Back+ or Diana Instant Back+, can be turned into a lightpainting device. All you need is an empty CR2 battery, a LED, a film container and some sticky tape.
There comes a point when the Instant Back+ is no longer working because the batteries are flat.
Don’t dispose the flat batteries! You can still use them for your lomographic pleasure!
What you need:
- CR2 battery – used one from your Instant Back+ or fresh ones (buying a fresh battery only for this is not really reasonable a cheap 3V button cell would do)
- LED – you can use any led that works with a voltage close to 3V (standard led)
- film container – you need a white diffused one, the black one is optional you can also use two white ones
- sticky tape – or gaffa or maybe a glue gun
- a tiny slot screwdriver – not really essential scissors would do !
What to do?
Attach the LED to the battery and fix it with sticky tape as shown in step’s A to F. Connect the long leg with the positive (+) end of the battery (if you can’t find a longer leg simply try out which way the LED should be connected).
Make a little hole in the cap of the diffused (white) film container (I used the tiny slot screwdriver for this ) G&H. Put the cap on the LED and then back on the film container, It should now look like “I”.
Now put the black film container over the battery and fix it with sticky tape.
The LED should now glow for something between a few hours up to a few days depending on the led and the residual charge of the battery.
Try to use the light for lightpainting and some long-exposure fun!
