Circuit Blocks

Build this for Fletcher in a few years.

Wood blocks with electric components mounted on them.

Blocks

• Power
  • Battery
  • DC source
• Motor
• LED
  • Reversed pairs
  • Tri color
• 555: astable, with 2 pots to change frequency and on time
• Switch
• Button
• Buzzer
• Fan
• Light detector: 2 outputs inverse of each other, one for light, one for dark
• Electro magnet
• Magnetic switch (or build one with a Hall sensor)

I'd really like a good connector that is solid, but also that he can easily use. Banana plugs would be good. Something with magnets might also work.

I could use magnets and have the power on the side of the blocks. Signal wires would still need to be connected manually on top of things.
