Node-Red Tabs on Raspberry Pi
Good Morning! In my previous post on using mqtt with Node-Red, @mytechtrail had asked how to add different tabs for the different flows that could be on separate Pi's. Additionally I'll share with you

Prototyping and Breadboarding your circuits
Good Morning! Most of my posts have covered the software side of my systems. I did go through wiring up the 12V LED light strips to the Pi with MOSFETS in Part III of the Raspberry Pi Home Automation series.

Raspberry Pi Home Automation Part V
In part 4 of this series I shared some pictures of the LED light strips in action and the small relay board that I use when I want to control a device with power that is independent of the Raspberry Pi.

Raspberry Pi Home Automation Part III
In my second post I shared how easy it was to recycle an old PC power supply. Just don't forget the fuses, my PS can deliver 5V @ 15A & +12V @ 16A & 18A, more than enough to damage your circuits
