Some time back I came across an article in a magazine where a boy lost his leg thanks to his habit of balancing on chairs. I thought why not build a tilt sensor alarm for chairs before calamity struck me too. So I came up with this simple tilt sensor circuit which doesn't really need any instructions to build.
Materials Required:
Materials Required:
- A Piezo Buzzer
- A 9v Battery
- A 9v Battery Connector
- A dead AAA battery
- A small and thin magnet
- A small box to keep the circuit compact
- Aluminium foil or any small conductive sheet
Tools Required:
- Insulation tape
- Double sided tape
- Soldering iron and solder instead of insulation tape
Step by step instructions:
Now you can place this circuit wherever you like and use it as a tilt sensor. Of course the smaller the piezo buzzer, the battery and the rolling element, the more compact the circuit box. Simple as that!

The Tilt Sensor Circuit
|
- Scrap off the paint of a dead battery
- Cut two pieces of aluminium foil of about 1cm X 1cm
- Connect the positive end of the battery connector to the positive end of the piezo buzzer by twisting the copper strands together or by soldering
- Fix the magnet on one side of the box as indicated in the images above so that the battery remains stuck to the contact points for a while
- Stick the negative ends of the buzzer and battery on either side of the magnet keeping in mind their alignment with the rolling battery
- Stick the aluminium foils on top of the negative ends to improve connectivity on the contact points
- Arrange the circuit in your box as indicated in the images above and do the necessary for aesthetic beauty :)

Hard Luck for those who love to balance on chairs! |
