I would pay like $200 for one the size of a keychain flashlight, that was also a flashlight.
Please get on that.
This will be the first project I work on when I arrive in SF. I'll need the cash after 10 weeks on a bike.
Maybe one could be made with this?
That would be bigger than a keychain flashlight. I presume that jwz is looking for something in the form factor of a Photon.
If it could be penlight - size rather than keyfob-size, that would expand the possibilities.
This even has a USB port already.
Absolutely not. I'm not one of you Keychain Maximalists who lugs around a carabiner with a twelve pound sack of keys. If it doesn't fit on my keychain, it won't be with me.
If I could have one key I would.
I even think the Photon is too big.
Would it be acceptable to have a switch to toggle between the IR LED and the standard white LED for the flashlight?
here's plans for one...someone get crackin'
or loan me an AVR programmer...
That actually looks almost perfect, if it had a housing. Otherwise it will get torn up in a day of pocket life.
This looks like the kind of thing 3-d printing might actually be useful for. If the pvc doesn't seem tough enough, a coating or two of epoxy would probably do the trick.
Worst case, just get some heat shrink tubing.
Hell, that's overthinking it. Hot glue everything that isn't the button and the battery holder. Don't go to Boston with it, but otherwise it'd be durable enough.
That said, it can get even smaller: http://interactive-matter.eu/blog/2009/07/04/µtvbg-tv-b-gone-clone/ - 14.5mm x 25mm
Lose the programming header and it looks like you'd almost be limited by the battery choice. I'd stick with 2032 because the capacity drops off rapidly below the 20mm cells, but 1220's aren't terrible.
adafruit sells them preprogrammed: http://www.adafruit.com/products/75
I'm wondering why Apple hasn't sued them for their latest.
http://www.thinkgeek.com/product/9a06/ seems more fully-featured, and also smaller. I upgraded my mother from the TV-B-Gone to this, she really likes the ability to mute and change channels, it makes her feel more empowered to mess with others.
It looks a little smaller than TV-B-Gone, but it's still far too big for my tastes.
It's becoming increasingly common to see these things built in to a hat and constantly transmitting. Bonus points if you put an array of transmitting LEDs around the hat to blind cheap security cameras in all directions.
Clearly we travel in different circles.
Ok, it's not also a flashlight, but it's most of the way there and it's in a nice case (one of these) unlike other tiny versions out there.
I think the big issues with one that small are going to be distance and battery longevity. If your use case is when you're almost on top of the tv it might be okay but if you have to be right in front of it I'm not sure how useful it is. But I'm thinking of places that have jammed the evil boxes in top corners of the room; perhaps you're usually close to the damned things.
