My First OP-AMP Circuit

My Glassman high voltage power supply can be controlled with a 0-10VDC signal.

But most computer interfaces (like the arduino ) output 0-5VDC.

So today I built my first OP-AMP circuit to double a DC voltage:

I found a LM358M operation amplifier laying around.

Now I have a 2X voltage doubler! Sweet:
