do you feel motivated to dive into the lab?
11:04
se6astian
do you understand what it is for?
11:05
se6astian
we want to invite all crowd funding backers to it and we want to make sure people really know what this is and how important it is but also that they need to be active and cant just wait and let the others do the participation

good afternoon
15:31
surami
is somebody here knows something about 16v to 12v voltage reducers?
15:33
Bertl
you mean DC/DC converters?
15:35
philippej
what do you want to do ?
15:36
surami
i think on this: 1, http://www.batteryspace.com/nimhbatterypack168v10ah168wh14xdfordivinglightscooterrobote-bike.aspx -> 2, http://www.jasonsgolfcarts.com/16V_18V_TO_12V_Voltage_Reducer_10_Amp_p/volt-0001.htm -> 3, http://www.hd-plex.com/fanless-ATX-power-supply
15:36
surami
to give power to a mini-itx system
15:36
surami
mobile...
15:37
philippej
you might be able to find better battery options
15:37
surami
160W - 200W is needed
15:37
surami
something there
15:38
philippej
it will run out quickly :-)
15:40
surami
:) and my thinking is wrong with this stuffs what i linked :D
15:40
surami
how to power then a 160w system?
15:40
philippej
not sure but with a lipo you get better power-weight ratio, this for example : http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=16225
15:41
philippej
(for much less money :-) )
15:41
surami
here is the system what i thinginking about: http://uk.pcpartpicker.com/p/Hkct4D
15:42
philippej
how long do you want it to run ?
15:42
surami
1 hour
15:42
surami
and change the battery
15:43
surami
this system would be the recording device + workstation
15:44
surami
of course, when it would be in workstation mod
15:45
philippej
there are dc converters like this one : http://nz.wellforces.com/meanwell-rsd-200b-12-dc-dc-converter-200w-14-4-33-6v-in-12v-out-railway.html
15:45
surami
then the capture card should be switched to a more powerful videocard (so not the onboard)
15:45
philippej
then you can use higher voltage
15:46
philippej
for example this : http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=18210
15:46
surami
thanks philip i will investigate
15:47
philippej
I'm not sure but a dc converter is more efficient if the voltage difference is higher
15:47
philippej
I'm sure otoh that lipo have better weight/power ratio than nimh
15:49
surami
ok, thanks
15:50
surami
and the another problem is the case for this system :) :)
15:50
philippej
the link you sent with atx power supplies has some that accept 16-24v, might be a good fit for lipo
15:52
surami
ok, i have to think about it again then
15:53
surami
do you know a that kind of pcie x16 riser
15:53
surami
what makes 2 x16 switchable ports?
15:53
philippej
nope, sorry
15:54
surami
my thinkg is to put a capture card + the more powerfull video card on it
15:54
surami
and if i use the mini-itx for recording
15:55
surami
then the capture card is used
15:55
surami
and the mobile power supply with battery
15:55
surami
and if i use the system for working
15:55
surami
then i use another power source and swith to video card
15:56
surami
so no need for data transfer
15:56
surami
just make a dualboot system
15:56
surami
1 recording station
15:56
surami
1 working station
15:56
surami
in the same case
15:56
surami
power should be outside this box
15:57
surami
something like this
15:57
surami
i don't know if you could follow the thinking
15:57
surami
or how i mean
15:57
surami
back soon...
