Hello, greetings to all robot builders, I am eager to receive the board ez-b, to give life to my butler robot, robot weighing 2.5 to 3 kg, the wheel servos are 15kg of torque, modified for continuous rotation, arms and head as well these servos, body materials are cheap and easy to find, I have a lot of ideas for the project that I'd like to share. Ping 3 sensors and 1 sharp infrared, head with 2-axis motion, arms opening and closing hands, voice, etc. .. And all thanks to the fantastic product ez-b, which by its ease and flexibility, have encouraged me with this project, since my childhood I came in my mind. Here is a video with the current assembly.

Hi everybody! I want to tell you that the last week in Quito - Ecuador, we had 5 days of a technology party called...
R2D2, How did you wire the on off switch for the voltage regulator? The Bookmaker wants to know.
I have it connected in series with a power cable (not in parallel between the two wires) The red wire or the black (from the battery and ez-b,) you cut and insert the switch, and voila!
Hello R2D2, I already have a switch on the hot lead form the battery to the EZ-B however it does not control the voltage regulator which is pluged directly into the battery balance plug. How did you wire the voltage regulator on off to the on off of the EZ-B?
Bookmaker Hello, I suppose that when you write voltage regulator, you mean the voltage indicator three digits, only shows the voltage, but does not, then the switch is connected to the black wire lipo balancer connector with an extension male-female balancer the operation is safer for the battery, the black wire is common to all elements of the battery. Hope this helps you, greetings.
Thanks R2D2, I kind of came to the same conclusion. I ordered the extension since my local hobby store didn't have one. I assumed the black ground would be the one to switch and thanks for confirming.
R2D2, I am not very electronic savy so excuse my ignorance. Can i use 75ohm TV cable I have laying around or does it have to be 50 ohm for the extension antenna?
Bookmaker If its a short run of cable it won't make a lot of difference 75ohm is just a bit thicker and not as manageable. I want to try this as well so let us know how you get on and if it improves the range
Hey, better if 50 ohm, 75 ohm cable also improves the scope, but not being of its impedance, I can not guarantee the survival of the Bluetooth module, part of the emission power back down the cable into the circuit, because it radiates all the power (SWR) ratio waves. I think for the price of a piece of 50 ohm cable (RG58) in my case, not worth risking the physical integrity of the bluetooth module, plus a further performance boost.
