Tech question about DC-DC voltage converter

[He Man]

is there such a device that you can hook up to your bike so it you could hook it up to a device that normally runs on battery only?

[mookieo2]

What voltage does the device you want to hook up need? There are plenty of converters out there. You need to be more specific.

[Major Slow]

yes

stnadard battery voltages... 1.5v and 3v

You really need to use google...

No, it's not possible.

A very thin 200 meter cable to loose whatever is needed? (I don't even know if I'm joking)

My 9V battery operated glove liners (another joke) became MUCH hotter with the 12/13/14 volts off my bike.
Their controller box reduces the heat ~ "a lot" - no idea how much in terms of voltage.
Maybe a/your Gerbing controller can do it?

look up a lm317 regulator It is good for a variety of voltages and is really a good all around regulator it sources 1.5 amps. http://www.google.com/search?q=lm317+datasheet&rls=com.microsoft:en-us:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7&rlz=1I7ADBF

i found a lot of shit for cars. but stuff for cars arent waterproof and are exposed or huge pieces of equipment.

I googled the topic and it seems others have the same idea as me. Cameras that run on battery only, or other crap. And there are voltage regulators out thre that you could put into a box, but im looking for something premade. They have a LM317 like thing at radioshack. like the dial found on the Fatduc modulator.

What i want to do is power my Go pro cam. The battery life on it is a joke (20-40mins depending on temp, vibration and if its on video/picture mode, yes i am using rechargeables, no i will not just buy $8 lithium batteries every time i want to use it.

When I asked GoPro about a wall charger converter, they told me to get anything with a USB socket and 5 volts.
My point is that 5 volts is what the camera needs to charge.
Are you planning to connect wires directly to the camera, ditching the battery? (extra batteries are only $20?)

What voltage is a cell phone?

What voltage is a cell phone?

Happily, 5VDC.  I'm researching using a (car) cell phone charger guts to power a GPS.  Trouble with most of them (cell chargers) is the power output is only 200-300 mA.  The handheld GPS I've got needs 500 mA.

If you look carefully at the camera, there should be an indication of the power draw.  I don't have a video cam, so can't even guess.

So...

if the camera requires less than 500 mA you could theoretically add a 12v lighter socket and a cell phone charger in a tank bag.

Go-pro shows a charger for the HD hero. Part# acarc-001 Have you seen that?

[He Man]

it doenst say anything about mAh. But what i did read on it (Thats not mentioned on the website) is the fact that it says you must use lithiums when in high vibration use.

The problem isnt cost of a rechargeble battery, but the fact that a battery doesnt last very long and if i wanted to just leave the camera on for an hour, id need to carry 6 batteries and swap them out every 20 minutes.

I planned to drill a hole on the backside of the case and put 2 wires that ill solder it directly onto a dummy battery then seal it with some silicone.


ducpainter the SD Go Pro does not support internal charging. the HD Hero support it, but it also comes with a lithium rechargebale pack that is resistant to shock.

coin up...

buy the good one.
