8v power output, for Canon camera added to my DIY power mount hub

[Guest]

Well I felt I should have done this right from the start, put an 8v output on my DIY power hub for my Canon 1000D camera, saves on changing batteries, also gets rid of a lot of the heat from inside the camera.

Here is a picture of the finished project

For loads more pics of the whole process of fitting this, with description, then have a look at my website here:

Thanks a lot, why not check out my website, and you will see how to build the whole power hub.

I don't know if it will make a difference, but the running voltage of most Canon DSLR's is 7.4V there is a Voltage regulator that does this voltage, a member did offer them at cost as he had to buy 25, i think there were £1 each, this was a year or 2 in the past...

No it's fine, it is an 8v regulator which gives around 7.8v the camera can take up to around 8.5v without damage.

These are the actual regulators that Astronomiser use on all there DC power adapters for the canon cameras, as this regulator came from an old one of them. I bought years ago.

7.4v is the minimum voltage for Canon EOS DSLRs and represents a flat battery.  A fully charged battery gives well over 8v (I forget the exact value) so it's perfectly fine to run off an 8v external supply.  BTW if you connect the middle contact to ground/0v the camera will report it as running off external power.

I have a Canon battery grip that has an AA battery adaptor this runs at 9V well 9.6V with a fresh set of Duracells.

Hi Gina,

I have connected the middle contact to ground, I think, well it is connected to the negative terminal, and the battery indicator on the camera shows as being full, so how does that differ from showing of running from mains, does it show a different icon on the camera??

This is an image of the screen on the camera when connected to the new 8v supply.

Software such as APT shows a different icon.  Don't know about the camera LCD as I only use DSLRs for astro without the LCD.  My general purpose 1100D uses battery power.

Geez you could sell those ! Looks quite nice and cool

Kendrick sells this at around 250£... I wish I was more a DIY kind of guy...

So was I correct in connecting the middle terminal on the battery connector to the negative terminal next to it, so basically positive on one terminal and negative to the other two.

Thanks for the comment

Yes I did think about building a few and trying to sell them, it was just that it is far cheaper to buy the components in bulk, so wanted to see if there was any interest, and the hardest part was cutting the holes in the box, So if I was doing a few I would get them laser cut.

So was thinking of selling complete hubs as shown on my website, for around £170 including the 8v output, which was added later.

Yes, absolutely correct

Would something like this works too ? I am not too good at soldering, it looks easier on this board than what you did (the one you show on your website) ... less skills required !

They power my camera fine what you will need is a discarded battery to use as an adapter to fit in the camera, I bought some cheap ones off ebay and removed the inards apart from the circuit board (cutting a few tracks to disable the circuitry) and soldered on a lead.

The alternative is to modify a battery grip with a socket of some description. My grip came with two adapters one for canon batteries and one for AA cells that could be easily modded for use with the dc-dc convertor.

I already have the camera battery adapter from a 120Vac power supply I used at home. I guess I just need to take the wire that goes to the battery, strip it and put a connector (XLR?) at the end ? Saves me from buying an Astronomiser
