Hey guys, sorry for the noobish question, but I just took my completely stock Headplay unit out of storage to do some FPV, and while the liberator turns on fine with the blue lighted power button, there's no signal to the goggles themselves, i.e. they just don't turn on at all. Does anyone have any idea what I could try to debug this, or what could be causing it? Could it be a burnt fuse even though the power button lights up? I've never used a power source other than the stock adapter.

Any help or guidance would be much appreciated. Thanks!

Hi,
maybe the connector is broken ...

Thanks Thomas. I've tried wiggling the connector around as much as I could, and nothing happened. I did use a multimeter to check for continuity in the fuses and they seem fine. If anyone has any idea of how I could use the multimeter to check for other things that may be wrong I'd appreciate any guidance.

Hi acky,

yes, works very well for me!
but only if the glasses have no frames from the 70ties
with the ski goggles the alignement of the headplays is always correct, because the nose is centering the goggles. you never have to re-correct the angle or the pupil-distance.

Sweet! No 70ties frames here!
Will put the order for the googles today
I've been using duck tape to block out the light works well but won't last long and it took awhile to do so that I didn't end up with tape stuck to my face!

I have the goggles and wear reading glasses. The edge where the hinge is touches the HP's. It doesn't hurt the viewing and perhaps helps by keeping the HP lenses at a fixed distance from my glasses so the focus is spot on.

Has anyone used a VGA converter to reduce the lag and improve the color saturation of headplays? I get a little lag and the colors look washed out on my ntsc input.

O.K. I am confused (so what is new ) ,,but the thread starts out with using 3S on the head play ,, and then I started reading that you are using 2 S ???
I have checked the voltage from the hp charger and it is indeed 12 V ... why using 7.4 ?

Or I probably missed something in my fast reading of all 92 pages of this thread
But wanted to be subed to it anyhow as I have an hp unit recieved in a used hexa deal and like what I am seeing with it ... but want to do all the mods talked about here before using it a lot .
Thanks
Larry

OK quick summary for you

some people started out using a 3s lipo directly powering the HPs through the main power jack.
Some people have had no issue at all with this set up some people have blown the onborad fuses due to in rush current.

Some people have figured out a way to use 3s with a resistor to limit the in rush current and some people, including me, used a voltage regulator limited to 12v and 1amp with no issue.

The original HP lipo battery was a 2s and hence people have figured out a way to connect a hobby lipo to the internal battery input wich is rated for 2s not 3s.
This seems to be teh safest way to not blow fuses but is more complicate.

Range video have released a liberator protector that is supplied with a neat little power board that plugs into the HP original battery bay which makes it very easy to connect a standard 2s lipo using the JST XH ballance plug.
nice and simple

SO

you can still use a 3s lipo to power the main unit but you have to limit the inrush current some how either with resistor or V Reg.

All the info is in this thread but i realise its not that easy to find.

hope that helps

Ben
