I am experiencing the same issue. I have exactly 0 soldering skills and I have done only the most basic of proto- breadboarding. (I also do not have the HDK. )
Yes, I am using the USB power bit connected to a wall plug. My circuit is USB power bit, button, cloudBit, Split, split branch one goes to a number bit + servo, branch two goes to the Lightwire bit.
For the short period of time the servo works, I can visibly see the lightwire flicker every time the servo changes direction. I have noticed that if anything else is plugged into that same outlet, the servo resets the cloudBit in a very short period of time. If the outlet is only occupied by the littleBits wall plug, it seems to reset after a significantly longer time period.
I acknowledge that it could be really be my house, actually. It's 100 years old and does not have the most up-to-date wiring LOL.
If that is what it is, any tips for regulating/prioritizing the flow of electricity for/to a single outlet?
Are there any simpler (even if less effective) ways of minimizing this effect?
