Apcki Posted January 31, 2017 Report Share Posted January 31, 2017 So I noticed that the Rodelink wireless system has an option to power the unit through a micro usb cable instead of batteries. I've got a BDS system but unfortunately no one (including Rode) sells a micro usb to barrel DC cable. Anyone have any success making one? I tried but can't seem to get a working one.

codyman Posted January 31, 2017 Report Share Posted January 31, 2017 Remote Audio does make a DC to USB cable although you'll have to also then hook up a usb micro cable to it. Quote Link to comment Share on other sites More sharing options...

Apcki Posted February 2, 2017 Author Report Share Posted February 2, 2017 @codyman I did notice that, but was going to see if I could find a cheaper solution first. I picked up a switchcraft 761k barrel plug, which I hope will do it. I do see myself just buying that cable in the end if I can't figure this out though, lol.

The issue is not so much that you'll need the right connectors as you need the right voltage. USB is 5VDC, where the outputs of your BDS are (likely) 11-16VDC depending on the charge of your batteries. Quote Link to comment Share on other sites More sharing options...
chrismedr Posted February 7, 2017 Report Share Posted February 7, 2017 Kortwich has several 5V USB adapters (and I'm sure they make many more if you ask them)http://www.filmtontechnik.de/en/products-from-kortwich/power-supply/usb-5v/ but if you're aiming for under 30bucks, then DIY with some chinese ebay components is probably the way to go. random links:http://www.ebay.de/itm/DC-DC-Converter-12V-Step-Down-Modul-5V-3A-15W-Power-Adapter-mit-Mini-USB-Kabel-/262766040412?hash=item3d2e13955c:g:XrgAAOSw5cNYVLvu http://www.ebay.de/itm/1PCS-DC-DC-Converter-Regulator-12V-to-5V-3A-15W-Car-Led-Display-Power-YS/182243122407?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D20140117130753%26meid%3D83918d976c65488c9b21886fe95c1089%26pid%3D100005%26rk%3D4%26rkt%3D6%26sd%3D181591369076 Quote Link to comment Share on other sites More sharing options...
Constantin Posted February 7, 2017 Report Share Posted February 7, 2017 The issue is not so much that you'll need the right connectors as you need the right voltage. USB is 5VDC, where the outputs of your BDS are (likely) 11-16VDC depending on the charge of your batteries. Remote Audio has a BDS with a regulated 5V USB output, and I'm sure others do, too.In fact, most of the outputs from (commercial) BDSs are regulated Quote Link to comment Share on other sites More sharing options...
DanieldH Posted February 9, 2017 Report Share Posted February 9, 2017 For reference: Blue Cow Cables should be able to make one, though they don't advertise. http://www.productionwiring.com/86-usb-power-cables. I have the Hirose one. The USB 5V regulator is a simple car charger. Quote Link to comment Share on other sites More sharing options...
Joon Pontén Posted February 11, 2017 Report Share Posted February 11, 2017 I used to have a lot of issues with noise/hum powering my Røde links externally, until I (with help from Røde's excellent support) realized that I couldn't power my SQN 4s mixer via barrel DC->Hirose and use the same powerbank's USB output as that resulted in some kind of ground loop. Now I power my Røde links from small USB emergency chargers, which works very nicely. Quote Link to comment Share on other sites More sharing options...
Apcki Posted February 25, 2017 Author Report Share Posted February 25, 2017 Joon, you seem to be right. I was finally able to wire something that worked, used a 12v to 5v converter to get the power to the right voltage, but I am getting a ground loop when using the battery as well. I'll have to try the small charger to see if that works. Quote Link to comment Share on other sites More sharing options...
