Electronics you can actually build

Electronics for eight-year-olds, on the same simulator the rest of Ohmsville runs on. Parts are chunky blocks you snap together by tapping two of them; a light comes on, a speaker sings, and the sun changes the sound. No sign-in, no typing, no camera, and nothing a child writes leaves the browser — because there is nowhere in here to write.

Hi! I'm Rezzy. Let's make a light come on!

Eight things to build

The first four you build yourself. The last four are built for you — your job is to change them.

  1. 1 You build it press → glow! Make a light come on Press the button and the red light comes on.
  2. 2 You build it turn → dimmer… Turn the knob, fade the light Turn the knob and the light goes from bright to almost gone.
  3. 3 You build it one path, they share Two lights on one path Put both lights on one path and watch them share.
  4. 4 You build it two paths, both bright! Two lights, two paths Give each light its own path and they both go bright.
  5. 5 Built for you hold… it creeps on A light that takes its time Hold the button and the light creeps on slowly.
  6. 6 Built for you tick… tock… forever Two lights taking turns Two lights blinking, one after the other, forever.
  7. 7 Built for you so fast you HEAR it Make it sing The same circuit, so fast you hear it instead of see it.
  8. 8 Built for you move the sun → new note The sun changes the sound Move the sun and the note changes.
