8 channel Solid State Relay board

Look, it's geek. It's utter geek. But it's an 8 channel optically isolated set of Solid State relays which means you can control a bunch of mains lights via a computer chip and run them as fast as you like because they're solid state.

I remember building lighting controllers when I was but a slip of a lad, and they used good old fashioned mechanical relays which clicked and clattered away, and if you ran them too fast, they burnt out.

Now - SOLID STATE!!! No moving parts! For about £8!!! It's bonkers! And optically isolated! Such joy! :-)

Oh I love my geek hobbies!
