do you feel motivated to dive into the lab?
10:04
se6astian
do you understand what it is for?
10:05
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
14:31
surami
is somebody here knows something about 16v to 12v voltage reducers?
14:33
Bertl
you mean DC/DC converters?
14:35
philippej
what do you want to do ?
14:36
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
14:36
surami
to give power to a mini-itx system
14:36
surami
mobile...
14:37
philippej
you might be able to find better battery options
14:37
surami
160W - 200W is needed
14:37
surami
something there
14:38
philippej
it will run out quickly :-)
14:40
surami
:) and my thinking is wrong with this stuffs what i linked :D
14:40
surami
how to power then a 160w system?
14:40
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
14:41
philippej
(for much less money :-) )
14:41
surami
here is the system what i thinginking about: http://uk.pcpartpicker.com/p/Hkct4D
14:42
philippej
how long do you want it to run ?
14:42
surami
1 hour
14:42
surami
and change the battery
14:43
surami
this system would be the recording device + workstation
14:44
surami
of course, when it would be in workstation mod
14:45
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
14:45
surami
then the capture card should be switched to a more powerful videocard (so not the onboard)
14:45
philippej
then you can use higher voltage
14:46
philippej
for example this : http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=18210
14:46
surami
thanks philip i will investigate
14:47
philippej
I'm not sure but a dc converter is more efficient if the voltage difference is higher
14:47
philippej
I'm sure otoh that lipo have better weight/power ratio than nimh
14:49
surami
ok, thanks
14:50
surami
and the another problem is the case for this system :) :)
14:50
philippej
the link you sent with atx power supplies has some that accept 16-24v, might be a good fit for lipo
14:52
surami
ok, i have to think about it again then
14:53
surami
do you know a that kind of pcie x16 riser
14:53
surami
what makes 2 x16 switchable ports?
14:53
philippej
nope, sorry
14:54
surami
my thinkg is to put a capture card + the more powerfull video card on it
14:54
surami
and if i use the mini-itx for recording
14:55
surami
then the capture card is used
14:55
surami
and the mobile power supply with battery
14:55
surami
and if i use the system for working
14:55
surami
then i use another power source and swith to video card
14:56
surami
so no need for data transfer
14:56
surami
just make a dualboot system
14:56
surami
1 recording station
14:56
surami
1 working station
14:56
surami
in the same case
14:56
surami
power should be outside this box
14:57
surami
something like this
14:57
surami
i don't know if you could follow the thinking
14:57
surami
or how i mean
14:57
surami
back soon...
