Trying to make Duplo more interesting... So far it is working (probably), seem to have encouraged my daughter to learn to stack two pieces together! 😃 Actually the next step after a fanfare is probably (not the stars but) to have pieces make different sounds and/or beats depending on sensors (ex sensing colors, stacking, proximity or sound) — a music machine. Perhaps more important: a programmer base plate; where you stack pieces & program them (from ex Arduino studio, for now). Inter-piece communication could also be interesting? Ideas?

Very nice! One idea I had is that would it be possible to create "water blocks" in which the "water" (light) would flow downwards when stacked.

That's a lovely idea! I'll try to add electronic contacts on the pogos/pins/pegs if/when that's successful such "water block" should be fairly straight forward, right? 🤔

Very cool! So much fun to share our hobbies with our kids! Reminds me just a bit of a very young version of https://modrobotics.com

@David Alan Hjelle I'm finding that very inspiring, I can feel many more ideas brewing 😃 PS. Did you ever play with this yourself?

Are you aware of LEGO’s Super Mario and Luigi figures? They have little displays and microprocessors and accelerometers and speakers in them. They do and say different things depending on their orientation and motion and position on a "special" base. My grandsons have some. I think that I played with them more than they did :-).

PS. Did you ever play with this yourself?

No, unfortunately. I've had them on my wish-list for years, ever since I saw a talk by one of their co-founders, but never percolated to the top.

Re. inter-piece communication, I’ve seen conductive fabric tape used to make connections between LEGOs, and I bet it would work for Duplos too.
