Decimal counter

[Rene]

Here is a full speed decimal block counter. It is modular, so the count can go up to as many digits as you want.

On the lower conveyer, you can even add small digits (0-6), but at slightly less than full speed

Design challenge: create a decimal adder that adds up all digits (0-9). Full speed would be nice.

Here's a quick one.

It's least significant digit first. I could probably reverse it but I'm lazy.
The first counter can't reset from 9 to 0 fast enough so it resets to 2 to account for the lost blocks. If the stream were going to be intermittent I would have to do it a bit different.
