Monza -Monarco or Brands Hatch

Would you just look at the speed that Bot goes .......

I think they should install Inverted Octal Bus Buffers into the Formula 1 cars at Monza (Italy).

Super slick direct design ........ Thumbs up .... or is it "Suns" up

Nice mate.

A Beam bot customised. A great project for us newbies.

You're certainly not the guy who went to malta! Great job!

(please refer to the italian man who went to malta joke if you don't know what i'm talking about)

I love the use of the logic

I love the use of the logic chip as a control mechanism. This is a nice change to all of the uProcs that we all use.

Great work and can't wait to see more.

EDIT: I did a bit of searching since I was damn curious about how the logic behind this worked and found an article on the sb board that goes into a similar design using the 74hc240 chip.

This helped me to understand a bit more of how the chip was utilized. Again, I have to say, great work on this design noise0. :)

I think this will help others in utilizing solar power in their bots.
