Turn it upside down and it switches off. Turn it right side up again and it switches on. 

This is draailampje (Dutch, pronounce 'dry-lamp-yea', means something like turn-light), my 'invention' or better said, creation.

You can make one for yourself in 10-30minutes, depending on your soldering skills. 

Tools:
  • soldering iron
  • soldering tin
  • wire cutters
  • small knife 
  • lighter (optional)
  • poster-stick-gum (optional)
Parts (available as kit):
  • mini jar
  • cr2032 holder
  • cr2032 battery
  • 10mm LED 
  • tilt / angle switch
  • dubble sided sticky tape / foam

Help is available, just comment on this instructable. Instructional video on youtube if you rather see me do it step by step. 

Kits, ready made and workshop kits available on my draailampje.nl website.

Step 1: Test LED and battery, fold LED leads into V shape

  1. Test the LED and battery by connecting the two (long lead on LED is )
  2. Fold leads of LED into V shape
  3. Fold 5mm of the - lead of LED (the short one) back a little

Step 2: Prepare battery holder

  1. Cut lead on underside of battery holder off (the one in the square bit), you don't have to be exact
  2. Fold -lead on underside of battery holder horizontal with battery holder, to the outside 

Step 3: Prepare angle/tilt switch

Half of the protective plastic of the tilt/angle switch needs to be removed since it needs to be soldered on. It's the bottom part of the plastic that needs to go, top part stays to keep it together better. 
  1. Use a knife to cut the plastic (careful, light pressure is enough)
  2. Remove bottom half of plastic from switch (the side opposite of the leads sticking out)
  3. Optional; use a lighter to heat the plastic for easy removal (WARNING poisonous fumes from plastic burning is not healthy, don't breathe fumes in, ventilate well and such)  
  4. Clip of one of the leads from the switch and SAVE IT! (we need it later on), WARNING use protective eyewear when clipping

I cannot find a tilt switch like the one you used. Where did you find it?

Hi Dan!

I bought it at a local electronics store here in The Netherlands, comparable to what RadioShack used to be (in the olden days that is). A tilt or angle switch search on eBay will probably give you plenty of options! (that is where I bought the first mass order)

Awesome! You know if it's current can be controlled by a dimmer or something like that?

David Bakker (author)  ThaisM3 months ago
Not yet... But hopefully someone will make one :)

Hmmm, and what about a switch to turn it ON/OFF?

OrenLederman10 months ago

Cool idea. I think i'll make one :)

David Bakker (author)  OrenLederman10 months ago

The pictures are stills from the video I took (play in VLC, shortcut to capture still) making the draailampjes. So much easier than making all the pictures separately :)

Very cute and nice idea!
Can make a variety of jars with different colored LEDs for efx on a table.

jars from bon maman jams and jellies are awesome!

Cool! Why don't you solder a capacitor in parallel with the LED? It would look more natural fading in and out ;)
David Bakker (author)  phckopper11 months ago
nice idea, will make it even better!

Very nice. Adding a resistor in series to the led might reduce the heat in the tilt switch. Try this site: http://led.linear1.org/1led.wiz
