It's so funny how many of us cut our teeth on the same things as kids.
One of my first memories is Christmas when I was 5 years old, getting a huge set of LEGOs.
I had *just* turned 7 when I got one of those "150-in-1" spring terminal kits. I very distinctly remember when I got it, too; I was away for the weekend with my uncle and my parents gave it to me when I got home! They had found it at a thrift store; it was essentially brand new, all the wires, the huge manual, the original box and everything. Years later, my mom told me that she was hesitant to buy it, because she thought it was way too advanced for a 7 year old, but my dad insisted. I had a habit of taking the appliances apart to see how they worked, so he felt that the kit might curtail that. It did!
Did anyone else here play with Capsela as a kid? I got a set when I was 8 and *holy shit* it blew my mind. Too me, they were even better than LEGOs! They were these clear plastic capsules that connected together via these short hexagonal tubes. There were various types of capsules: Motors, worm gears, differential drives, and sets of various gear ratios. There were also floats, wheels, treads, propellers, impellers, switches (plus wires), a battery pack, pumps, tubing and tons of other stuff!
So you could make little motorized platforms that rolled around, or with the floats and impellers/propellers you could make water based things! I learned so much about mechanics with that and it really helped give me a good foundation for locomotion when I started to build robots as a teenager.
They also came out with this motorized base; it could move in any direction and had several internal motors that you could use to mount other capsules on. It came with this big IR remote control that you could voice control! It could only learn 8 or so commands (this was the mid-90's, remember) but it still amazed me.
Good times, good times...
