  1. Hi Rob Thank you for making the inquiry for me. You beat me to it :-) I'm going to make something nice out of this. Probably with circuit brakers in the bottom battery plate, on/off switches for 12v and 24v out of the side of the plate and a nice cable with lemo connector on the bottom plate end and Dtap on the rear battery plate end. Pictures coming soon. Rob, you have a shadow/phantom as well, is that correct? What is your solution for flying hungry 24v cameras? Cheers!
  2. Hi Rob, Thanks for pointing me in the right direction! Jelle
  3. Hi Janice, Great advice. Probably the best way to go in those kind of situations. If your tripod has wheels it is even quicker to get it setup in the right place. If you own a Jerry Hill bracket (and want to spend money rather than save it ;-) ) there is another slightly different solution. It is called the Dock N Roll from Abracam. I guess lots of people on the forum already now about this clever mod. (http://www.steadicamforum.com/index.php?showtopic=19306) The downside is that it is for fixed shots only. But great for setting up frame for the director and anyone else concerned so you can keep your hands free while waiting. Cheers!
  4. Hi Alan, thank you for the advice. I make a lot of cables myself and fixed my modulus 3000 that had gone up in smoke (not because of my cables ;) ) a few weeks earlier. So I guess I would like to take on the challenge. Do you, or anyone else on the forum perhaps, already know where to find the DC converter? Or is there someone who has done something similar? Best regards, Jelle.
  5. Hi all, I own a Shadow sled and I'm mostly flying Alexas in 24v mode. Instead of switching two 12v batteries in series I have had a 24v battery plate made to Chris' example. http://www.steadicamforum.com/index.php?showtopic=14350 It allows me to attach the 24v batteries that come with the camera on the bottom of my sled and supplies the 24v system. A neat feature of the shadow sled is that it has a DC/DC step-down converter built in to convert the 24v to 14.4v (or something in that neighborhood) to supply the 12v system with power while simultaneously powering the camera with 24v. This is where my problem comes in. I'd like to use one of my 12v batteries on battery plate nr.1 to supply all the 12v systems and the 24v battery on the bottom battery plate nr.3 to solely power the camera and nothing else since the Alexa is hungry enough. What happens now is that as soon the 24v batt is attached it powers the DC/DC converter, even when I have my sled switched off. At some point when the voltage of my 12v batt drops low enough I assume the DC/DC system starts charging my 12v batt. I figure the best solution to meet my wishes is to switch the DC/DC converter off so it doesn't help power the 12v systems and more importantly doesn't start charging my 12v battery. Does anyone know if there is an elegant way to achieve this? I opened up the battery plate of the shadow sled to check out if it could be a simple solution but it looks quite complicated :-) Your insights are much appreciated. Cheers, Jelle.
