I hate to bring this topic up again, ( its been about a year ) 
Back last year I put two SuperCap rated 1.5f @ 5v in series ( 1.5f 10v ) on EZB's input servo power ( 6v Battery ) to prevent brownouts and its been very successful, and worked well. ( Stopped brownouts ).
But since converting some of InMoov's large scale HS-805BB servo's over to EZ-Robots HDD Servo's I've been getting Brownouts? So I tried various things but still kept getting brownouts.
I then put one of the 1.5f 5v caps on the 3.3v rail of the EZB as you recommended last year, but for some reason it prevents me from connecting to the ARC in Client mode? I've checked and double check and its wired up correctly and as soon as I've removed it, it connects OK! I've carried this out a number of times powering off and back on in-between and get the same results. I also tried other supercaps, just in-case these two have gone faulty, but still get the same result, regarding the wifi connection.
I measured the 3.3v rail, when the supercap is connected and its still 3.3v, so its not being pulled down at all?
Any ideas?
Cheers Chris.
If you have to hack the ezb for your project, then you're exceeding the current limitations. Exceeding power limitations is dangerous and could cause risk of fire or damage out the ezb.
Power the servos from the power source directly using modified peripheral cables or something like the inmoov servo breakout board.
The ezrobot servos will logically use more current than a larger servo. This is simply because the gear ratios are less than half that of a larger servo. Simple math means the servo motor has to work nearly twice as hard. Thus, drawing more current.
@cem... For my first inMoov I pretty much and stupidly powered the entire inMoov through an ezb and an ssc-32... Later I used a "servo power" board to power my servos separately... I either use 2 x 6V SLA bats in parallel or a 6V 50amp power supply now... I do not experience any brown outs... You could also do is use a separate power source for you ezb ... This way the servo movements won't affect the voltage levels to the ezb...

Yes, I should of done this in the beginning but was to eager to get started and finish, which is a bit of a joke, as it took me nearly a year to complete in the end, but to be fair to me I was diagnosed with a terminal illness in-between! As you suggested I should done this from the start.
But I still don't understand why putting a super cap on the 3.3v rail, stopped the wifi connecting? I know other have done this including yourself and haven't had this problem, hence why I've gone over and over it again to check I having made any mistakes or done something stupid.
@JD I do understand what you are saying and wasn't criticizing the HDD servo in any way, it a GREAT servo! I'm more interested in the above about stopping connecting to wifi in client mode with the cap on the 3.3v rail.
Thanks Chris.
@DJ,
The Supercap mod was recommended by your own hardware engineer Jeremie to help deal with servo inrush current causing brownouts. See post 15 in this thread: https://synthiam.com/Community/Questions/8686&page=2

Sorry to hear that mate. Dont give up... All the best.
..
I had blader cancer stage 3. Did quimo and removed blader. That was 2 years ago. Doc says its gone. God i hope so! Regards.
Sorry for being off topic...
