I'm sure most of you guys know of Vengit, the producers of the SBrick. I was thinking, since they already make the SBrick, a PF compatible element that Lego itself would never produce, maybe they could eventually expand their lineup to include more things? If they did so , what would you want them to make?
I'd like to see some adapters, to connect various other batteries to the PF system, like a cable that would go from a common 7.2v RC batter to a PF plug, or a snap for a 9v battery, or even a system that plugs into the wall, like the old train speed regulator. Also good would be some small motors, and a proportional switch.
Also along these lines, would it be a good thing if Lego endorsed this kind of thing, like they did for certain Mindstorms sensors?
