Hey guys(and gals), I need help to find some voltage regulators to regulate 12v 7.2A down to 9v ?A or down to something the ez-b can handle and still operate some sensors and 2 servos.
I also need help to find a servo that can handle ROTATING 5 pounds or so.
Preferably I want both sources to be ebay.
Thanks everyone!
When you say rotating a load of 5lbs, what do you mean? Is it a drive train or is it an arm lifting?
If it needs to lift anything then work out the distance from the pivot and find a servo with enough torque to lift the weight at the specified length (i.e. if it's 1 inch from pivot a 5lbs/inch servo will do, if it's 10 inches away you will need 50lbs per inch)
For the voltage reg. it needs to have an Voltage and AH output that can run a heavy duty servo, micro servo some sensors, and the
ez-b itself.
Thanks for all the replys and help!
This is just technical stuff for my big surprise project!
I'd use more than one regulator personally, it'll avoid any issues. Just work out the load of the kit you plan to attach to it and get a regulator (or regulators) that provide more than the current needed. Oversize the amps and it'll avoid heat issues too.
Voltage regulator: adjustable output, 12v 7.2AH down to something the ez-b can handle,
Servo: may get the one out of the store when it opens.
Rich, the head is round and sits on a 25 to 35* angle. All it needs to do is rotate. Because theres no weight change on either side I can assume I don't need to go to an extreme servo with crazy weight ratings.
Thanks for the help guys!
Technical manual here
EZ-B Version 3.1
Input Voltage (min): 5 Volts DC
Input Voltage (max): 17 Volts DC
Input Voltage (recommended): 7.2 Volts DC @ 3 Amps
Regulators are pretty cheap and small so, provided you aren't strapped for space in your build it would be worth spending another couple of bucks on a regulator for each hd servo or every 2-3 standard servos.
Just my 2 cents worth
Ez-b can go without any regulator.
Anyone with a link to something like this is welcome to post it.
Thanks for all the replys.
