How futuristic does this look.
Well ok, maybe not futuristic. But this is a new counterweight replacement, it uses spring-loaded take-up spools from a retractable washing line. These have power springs in them (like metal tape measures).
The second new thing is using RJ45 network cables as motor power leads. This is basically a way of getting cheap extension leads I don’t have to make up myself. Making up the cables was the really onerous bit about kitting, so this is the solution to that, as well as probably being more reliable.
The connections are very neat, and the cables are very affordable, and the extra conductors means that it’ll be quite easy to piggy-back endstop detectors on the same cable.
I’ve used the little sparkfun breakouts with 90 degree pin headers to connect into the screw terminals on the motorshield. The network cables are a lot stiffer than the old ones, so I’m a bit worried about the strength of the connections, but I’m pretty pleased with it.
Now, shepherds pie and carrots for dinner – rock on.
