Troubleshooting Circuits

An essential part of building electric circuits is identifying and solving problems when your circuit does not work. Here we address some typical problems and how to solve them.

Block alignment

1. Check that all your blocks are properly aligned and none are standing up on some sides.  Gently push them into place if needed.
2. If your circuit is still not working, use a multimeter to measure between each block by taking the measurement at two adjoining nuts.  Start from the point closest to the battery and work your way around the circuit.  If there is no electricity flow at a point, you have identified the block where the problem is. 
Check that this block is properly aligned.  If it is, go on to check the magnet at that point in the base.

Magnets not conducting electricity

  1. Check that the magnets are all properly moving up and down in their cavities by pressing down slightly on each block with a pencil.  If a magnet is stuck, manupulate it with the pencil to loosen it.
  2. Over time the magnets might develop a residue that could interfere with conductivity.  It is easy to remove this residue by gently scrubbing the base and magnets with a nailbrush or toothbrush under warm running water.

Battery power issue

  1. Check that your battery is not too flat to power your circuit.
  2. Check that the wire connection from the battery to the power blocks are still intact.

LEDs not lighting up

  1. If you forget to put a resistor in circuit with your LED, you will damage the LED and it will not longer function.  SeeBlocks Kit 1 comes with 4 LEDs so you have some backup LEDs.  We also sell replacement packs of LEDs, should you need them. 

Washing of your SeeBlocks

  1. It is perfectly safe to wash your SeeBlocks if they become dirty.  Simply rinse them in warm water and lay them out in a single layer on some newspaper or paper towel to dry.  Do not store them wet as this may cause corrosion.
