For my nephew's 1st birthday, which happens to be very close to a dear friend's daughters birthday, I wanted to experiment with making toy blocks with a bigger payoff.
I created two toy block sets with neopixels around the base that would respond to the colour of block being put on the base with the appropriate lights flickering. It's a pleasant sensory experience for toddlers.
The blocks were painted with non-toxic paint and covered in a non-toxic top coat for durability.
I made a custom circuit board with an IC running Arduino software. A weight sensor is what calculates what block/combo of blocks is on the base at any one time. There's also a rechargable LiPo battery.
I learned that toddlers are VIOLENT with their toys. Despite trying to make the best and rod as solid as possible with screws and glue, both toddlers broke theirs within a month. They really did enjoy them though! Going forward I'd like to make a more robust version to handle a beating.
