Other creative toys/products that come to mind would be, say, Play-Doh as a sort of children’s intro to…Clay, I suppose? But in this vein without being exclusively directed towards children (albeit I imagine many may be).
Always enjoyed a creative kind of toy to mess around with.
Ah yeah I remember those days. The progress KiCAD has made is nothing short of amazing.
I used to like the code simulator in AVR Studio 4, but since acquisition by Microchip it’s borderline unusable and crashes constantly.
Haven’t heard of iCircuit! Maybe I’ll give it a try.
