Can I use a mini jack to power things up? Answered
Hi, first of all I must apologize if I'm not being clear on the description of what I'm planning on doing (english is not my first language), there's a drwing if it can help understand what i'm trying to say.
So here's my "problem":
I have been building several devices (small LED lamps, robots and other geeky stuff I found here on Instructables) and I'm trying to find a good and "universal" solution to power them. Their energy consumption is low so I decided I could use a USB connection as the power source/supply.
Now, I would like to use a single cable to power all these, a "plug and play" solution and I've been thinking to jacks, the kind you find on headphones: easy to plug/unplug and I've got plenty of spare female jack plugs I can use with the devices (with the appropriate resistors included).
So basically I would end up using a cable with a male USB on one end and a male mini jack on the other.
Is it possible to use the jacks this way?
Will the mini jacks and/or the headphones cables stand the power from a USB source?
Thanks for your answers!
