Thanks Nomad. I'll check them out. The ones I originally used had a funny insulated block mid-way down. No idea why and they worked previously. I'm notorious for blowing circuits. An expensive hobby but I'm learning.

Alan I have a growing pile of dead servos I plan on using for an art project :-)

In general, when servos blow, it is the circuit board but not the motor, so you might be able to re-use the motors with cheap H-bridges, or as replacement parts on the rare occasions when a motor rather than a circuit board blows out.

But yeah, I have seen my share of expensive blue magic smoke in this hobby....

i only by here my parts.then am sure i got the wright ones, and warenty just incase.

my first bioloid i burn 10 servo's in one download,so your not alone. but it was also the fault off the seller,he was not annest man, and i say this whithout saying what he really was.

i always say,the more you break the more you learn.

The three wire cable if servos prevents them from blowing when plugged in backwards. You'll never damage a servo by connecting it backward. The ezb also has isolation resistors on the io to prevent backward servos from damaging the ezb.

If the servo doesn't work, it's been used and abused. Which is quite common for custom built robots. We're always trying to lift too much weight

DJ, that statement contradicts real life experience. I have two blown servos and the only abuse was plugging them in wrong.

Problem resolved on the servo. I severed the wiring close to the servo, replaced it and the signal connected. I must have damaged it.

great find.

Nice work! Little things like that are hard to find. When trouble shooting i always start with a simple voltage or continuity check to see it the power is getting from point A to B. You would be amazed how often that this is the problem.
