Re: Electronics/Handle packages for sale.
Would anyone prefer these to be wall-powered (220 or 120) vs. battery powered?

Re: Electronics/Handle packages for sale.
I just bought enough parts to make 15 of these, battery powered. 3 are spoken for. I will update this thread when the parts arrive and produce them shortly after.

I would. The unit I'm constructing has a powerstrip for driving the cameras and lights, adding one in for the trigger would be nice.daniel_reetz wrote:Would anyone prefer these to be wall-powered (220 or 120) vs. battery powered?

Re: Electronics/Handle packages for sale.
Yours will be. If others want a unit with a wall supply, they'll have to let me know in advance...
Re: Electronics/Handle packages for sale.
Put me down for one. I'd prefer a wall plug but I don't care considering you bought the battery packs. What type of batteries should I pick up to prep for when I get it shipped to me?

Re: Electronics/Handle packages for sale.
Cool. They are powered by 3AA batteries. I don't mind making you a wall-wart supply as well, but it might take me a bit to find some 5V power supplies. Let me search eBay a bit and see what I can find. I'll report back here.
Just for everyone's information, the battery powered versions are in principle a bit safer -- insensitive to power spikes, or to catastrophic failure of their little power supplies. And you can expect 3 alkaline AA batteries to last essentially forever, as the cameras will trigger down to around 3.5v. Should take years to trigger that many times.
I don't mean in any way to inspire fear or anything -- far from it -- and wall-adapter versions are actually a bit easier for me to make, but I will not be buying anyone new cameras if a meteor strikes your book scanner or a power surge blows up a little 5v supply or something.

Re: Electronics/Handle packages for sale.
Yep those were mostly my concerns.. thinking about it I'd prefer the battery packs now because you answered all my concerns already.. and then who knows with power supplies and I plan on maybe eventually making the setup automated if its possible... wouldn't want to leave the place with it plugged in and going by itself. I should be able to change it over by myself if i end up preferring the plug for whatever reason.

Who knew 5v power supplies were so dangerous?
Re: Electronics/Handle packages for sale.
I would like to put my name down for one of these if you still have one available. Battery powered will work for me.
Thanks.
Thanks.
