I use barrier strip because they handle 30 amps of current and customizable by using jumper plates. They are cheap online and reasonable prices in stores like radio shack. They are a common enough item that's the price stays low.

OK, so i've looked up a 12v distribution block, and all I can find is those huge fuse boxes. Any links for a distribution block that can handle 12v that has atleast 10 ports? (Also, do you have to solder the wires to the block?)

Also, where can i get the little ends that have a hole to connect to a signal plug? I only need the one plug hole if you have to solder the wires.

The connector blocks are rated in amps not volts. How many amps total are you going to be expecting to pull via one of the connector blocks?

The little ends are JST connections. You can buy a crimper and the ends however the crimpers are quite expensive (at least over here they are) and they are fiddly. I tent to cut jumper wires and servo extensions and solder them up as I require them. Or you could just use servo extensions, cut the red and black off close to the plug and leave the white for the signal. Just be careful not to short red to black.

i bought a crimmper about 4 years ago and it was around $45 usd. then i lent it to my father who promptly lost it.

They are about £80 over here, that's $100-120 ish... which is why I solder up the cables... Would love a crimper so I can do all my wiring perfectly though.

I use spade crimp connects and a 8 dollar crimper. You can use quick connects as well which are also crimp on. The spade connectors fit onto the barrier strip terminals perfectly.

The max Amperes a dynamixel itself can handle is 900 mA, so can i get a link for what i've said before that can handle that.
