| Mar 11, 2011 at 9:03 | comment | added | Kortuk | @DyalnVester, My switching regulators have never ever made a sound. I have never designed past 5A though. At my work our 1kA rectifier does make a nice little sound, but it is actually generating an audible range output frequency, our higher power supplies do not generate a sound. | |
| Mar 11, 2011 at 4:18 | comment | added | Dylan Vester | Thank you Kortuk, you did help spur me to do a little research on linear vs. switching regulators, that is why I chose you. Also, you made me consider whether I wanted a squealing or heat. My parts should arive in a day or two, and once I put it together, I'll post my findings. Thanks again! | |

| Mar 9, 2011 at 7:15 | comment | added | Kortuk | @DylanVester, I am glad my advice helped you, but it sounds like you found your own very specific solution. I may have guided you, but it seems like you could write your own answer about how you accomplished it and explain how to go about it. This could be very helpful to others. | |
| Mar 9, 2011 at 6:46 | comment | added | Dylan Vester | I found a good tutorial (ladyada.net/library/equipt/diypsupp.html) on creating a variable voltage regulator using this sparkfun.com/products/527 as well as some caps, a trim pot, and two diodes. I picked up a heatsink as well to be safe. Thanks again Kortuk. Btw, I chose an adjustable one, since I wanted to learn how to create it (for future projects). Also I'm going to ditch the dev board and create my own breadboard Arduino. | |

| Mar 9, 2011 at 5:19 | comment | added | Dylan Vester | Kortuk, Thank you very much for the reply. I guess what I'm looking for is kind of a pre-built circuit, a schematic, or something simple I can create that I can connect to an Arduino development board and power it from 24 volts. I've read that the minimum voltage that the development board will accept is 7 volts. So do you know of anything like this: sparkfun.com/products/9948 that will output above 7 volts? I know that the development board has it's own voltage regulator on it it, and I'm sure it's not the best practice to step-down from 24 volts...continued... | |
