I need a recommendation for a RELIABLE power source. I bought a cheap power adapter off Amazon (SoulBay brand), and after a week it sparked at the outlet when plugging in and stopped working. I bought a duplicate and it did the same thing.
I have been working off batteries since, but they drain SO fast.
Second:
I have a robotics project with 56 servos... SG90's (4.8 - 6V); 17 in the head and 6 for each hand... 13 25kg (4.8 - 6.8V) for the medium joints, and 14 60kg (6 - 8.4V) for the larger joints.
I am using a Raspberry Pi 4b, and chained 4 PCA9685.
All motors work with a 4AA battery pack. Although the larger motors barely work and really need more voltage to work best.
All 60kg's are on one PCA9685.
I have not been able to figure out how to run the larger motors on a higher voltage, while on the same chain.
I have considered running a secondary Pi with the larger motors on an isolated board, taking commands from the primary Pi?
I am a total amateur... I've been working on this project almost a year... have since learned 3d modeling, 3d printing, soldering, Python... but the power electronics stuff still eludes me!
Bless you for any advice!
