So I know about the specs and usage, even advice not to use it. NOT what Im asking but more of inputs on using my benchtop ADC regulated power supply. Im using this model in particular: Radio Shack 22-504 Regulated Power Supply 3 AMP 13.8 VDC, I have three SMD LED strip, appx 12 SMD LED per strip, power draw fine, added another line to power Arduino Uno, its just fine so far also. Arduino has LED x6 and LCD I2C x1 buzzer x1 attached.
Question: is any long term damage or running off the barrel jack? Short life span? Not enough or too much?
Reasoning for use/question: if I use 5V 2amp on barrel jack LCD won't work but lights up. But all (of course) works on USB 5V? But Im tired of leaving it plugged to computer and computer staying on, even with powered USB hub comp has to be on. I can use my SATA Shield with 5V in and one 5V out molex for devices, but don't want that either because I hate leaving it powered on it and HDD's spinning with no computer needs for it.
So...built barrel jack adaptor and plugged into benchtop regulated power supply then arduino..
Sorry second post ever, and second post EVER on internet, so if I ask for help wrong...sorry. Figured I come out observer mode to start contributing if I can.
