@robo-pi :) Some times it's an issue of "forest for the trees." Some times there's road construction too.

Sorry to be late to the show, but I believe you have a significant issue with your design. The schematic shows the the LEDs are being driven by the ou...

@fhaddad Correct, except that there will also be power losses in the buck/boost converter. I would expect about 25% loss in charge capacity (mAh). To ...

Power Supply Question: I was able to view the video, but only after I down loaded it. What I see is a candle, a big bottle of Kombucha, and a power su...

You should be just fine. max of 5 mA for the pots and joy sticks, and (if I remember correctly) 15 mA for the nRF.

@chickenhawk How much current can you draw out of the 5V pin on the mega2560? Nobody knows. However, there seems to be consensus on a few facts. Powe...

Good one... I'm looking forward to hearing some responses. I've mused on this one in the past and I always come back to, "How does the sleeping dog wa...

@chickenhawk Voltage drop is some times referred to IR drop. That is, current times resistance. If I assume that the wire lengths in question are less...

@chickenhawk I don't believe it matters. I can't imagine there is enough current flowing to justify a bus rail. I'd go for what ever looks better and ...

Shooting in the dark here (or at best early dawn), as I do not have details of the power requirements and layout for the individual components. Howeve...

@pugwash Yep! looks like the 32 byte buffer strikes again. I changed the wire.right part to output incremental data. Then split the wire.read part to ...

@pugwash Are you getting back all 32 bytes correctly now, or are you having the exact same response. Just guessing now and will have to run this code...

Problem identified. Solution to follow? I found this tonight... This page Identifies the Oddity of "30" as being an issue with the Wire library. It ...

@garnold Looks good. It's pretty much what I have. Plus an old cheapy I bought years ago at Canadian Tire. I've often used them in tandem when messing...

@dankramer That's what I see, as well. Except that there is a bus arbitration/priority scheme that helps to reduce collisions. What I am trying to ge...
