I have Ball type J-Sticks.
When the 'retro-fit kit' is available I can apply and add native support for them for MaLa Frontend. ;D

OK I ordered 1.. I could not resist :-)

Has anybody determined the current requirements for the USB source that's powering the ServoStik servos?
I'm currently using a Belkin F5U027, which used a 4 A power supply:

I'd like to free up one of those "smart" slots on my USB hub & use a "dumb" AC-USB adapter (like the stump that plugs into the wall for a cell phone charger). I have AC-USB adapters that go as high as 1 A, but when I hit the button to rotate the restrictor (I'm using hardware mode), I get no motion--if I listen closely, I hear a super faint whine.
1 amp seems to be insufficient. 4 amps seems to be plenty. Anybody have any intermediate data points to find the threshold?
Thanks,
-Jason

How have I not noticed this before? Bloody brilliant! When I get back home in a week imma see if I have the right sort of sticks. Might get an upgrade (",)

USB ports are rated at 500mA and they are designed to work with this amount of current. In fact the motor is limited to around 400mA. If it rises above this the controller assumes it has reached the end of travel and cuts out. If the restrictor is not completely switching this needs to be looked into. We changed the dimensions of the restrictor since the first batch of these to prevent binding.

Just checked mine. They are listed as Sanwa JS01 from the guys I bought them from. Is this the same as the JLW? Looks a hell of a lot like it.
