Wanted: 12V Adapter for Canon 300D or a link to where I can get one from.

Hi Paul,
Most of the 12v adapters I have seen are for charging the battery, not running the camera.
Found this link, if you are handy at electronics(or know someone who is)
Hope it helps.

Thanks Adrian I'll have word to my local electronics guru and see what can be done.

Paul, do you think this guru could make a few more?

I'll see what I can do, though I'm sure there are a few on the site here that could make a coupla extra bucks whipping up a few.

Maybe we should put the word out Fahim.

I'd pay someone here to make me a 12V adapter to run my 350D!

netwolf · #8 24-10-2007, 06:54 PM

Paul, yes I am sure and i would be happy to pay for it also.

What would be ideal is to make a dual kit AC and DC.

Fahim

Get in line you two

Better put the call out.

I have what you are looking for, from my G1 olden days. Basically it is a CA-PS400 "compact power adapter" plus DR-400 "DC Coupler". The output from the power adapter is 8.1V at 1.8A. I can't part with the CA-PS400, but to be honest I've never used the DR-400 component of it.

Here is another workable home built solution: http://home.arcor.de/panacocha/astro...10d_power.html

Those in the know will know that I currently have two clone BP511 packs that could be had by anyone willing to pick them up (no mail Li-ion battery of questionable origin...). They could be used in the creation of one of these power supplies. I could probably strip out the battery component and mail the casing.

I'd love to be able to understand what you said Eric, but as an electronics wiz I make a great landscaper. But thank goodness for google I see what you have. The DR-400 wouldn't fit a 300D would it?

citivolus (Ric) · #12 24-10-2007, 11:49 PM

I suspect that it would fit a 300D. Look around the battery door for a small sliding tab that accommodates the power cable. If there is one, it should fit. Then it would just be a case of supplying it with around 8V DC. Several sites I just checked said that the DR-400 will fit the 300D.

I had a go at removing the casing from the old BP-511 clones, but they are on there fairly well. I will fully discharge those batteries and then have a better go. I got too distracted playing with my new green laser pointer in the smoke from the fires on North Stradbroke Island to try too hard tonight

Oops, I just realized you were after a 12V source. That I don't have, but as posted above, a few minutes with a soldering iron and a DR-400 would provide you.

[1ponders] (Paul) · #14 25-10-2007, 07:15 AM

Thanks Eric. If you are prepared to part with the DR-400 I'd be happy to come to some sort of arrangement. Pm me and we'll chat.

Those circuits use a relatively expensive ($20US), no longer supported voltage regulator, which can be replaced with a 7808 costing $1.20 at Jaycar. This component is in a TO-220 case and is much smaller as well. I guess when people are ordering "free" samples, they don't pay much attention to the cost of the part in question. No wonder they couldn't find anyone selling those parts.

I might look into building some 11-35V to 8V power converters if there is enough interest. People would still need to supply their own BP-511 case or DR-400 on one end. Cost would likely be under $20 each, I'd have to do a more detailed parts breakdown and see what I could get for cases.

I'll do some more research and narrow down the price range. If I could get an idea for how many people were actually looking for a supply, that would help.

citivolus (Ric) · #16 25-10-2007, 03:43 PM

Oh, the one circuit uses the LM350T which is around the same price as a 7808 regulator, but requires a small amount of supporting circuitry. You can drop a few caps and resistors using the 7808, reducing the size and cost of the design slightly.

Edit: I take it back, if you want reverse polarity protection via a diode on the input, the 7808 gets you very close to 12V minimum input, so if you really need that extra volt of input range, the LM350T is better.
