Hey Jeremie, can you tell me what size cap you were using to smooth out the power supply DJ was using to power inMoov with?
Thanks Dude
It was two 1Farad 2.5V aerogel caps in series placed on the 3.3V line. This makes a 0.5F 5V rated cap.
P.S. I got beer and pizza when I got home... so it wasn't too bad.... LOL
To sustain the input voltage, like you said, a very large cap would be needed. When using servos there is usually many voltage/current spikes on the input side which are hard to filter and sustain while the regulated 3.3V is slightly buffered from it due to it's low voltage input requirements.
I wouldn't recommend using large caps on the input voltage, they will likely be quite expensive for higher rated voltages and there's no guarantee that they can do the job.
I have found some on eBay for $10 for 3... 1 Farad 2.5V...
