key fob case for 315mhz transmitter

Wireless & IoT

I’m making (yet another, everyone seems to be making these) interval timer for my Canon camera. I’m using http://www.sparkfun.com/commerce/produc … ts_id=8945 as the transmitter for a wireless trigger.

I’m trying to find an appropriate case for it, and struggling. The range/reliability isn’t good enough for me running it off a 3v CR2032, so I’d like to use a 12v A23 (if anyone has suggestions for other small batteries between 6v and 12v, I’ll listen to those, too).

I want to put it in a key fob. The 11121.4 from here: http://tekoenclosures.com/enclosures/pocket-keyfob.htm looks good, but the only distributor I can find that will ship to the US charges over $50 for that shipping.

Does anyone know where I can get something like that reasonably priced in the US?

I may just end up buying this http://bit.ly/10Gxa and ignoring the electronics it comes with, using only the case.

Google search on key fob enclosures came up with this http://www.polycase.com/contact

I’ve looked at Polycase’s key fobs, and they’re not big enough for the 12V battery. I want a stock part, not something custom, since this is just for a hobby project.

I’ll probably end up going with one of these: http://serpac.com/Products/Cseries/c-8.aspx, and just mount a switch on it. Should do fine, and fits everything pretty well.

They have an office in PA. They will readily sample without much pleading.

I emailed the seller of the ebay auction above (http://bit.ly/10Gxa) and he’s selling me just the transmitter cases for $0.50 each plus $5 shipping. I’ll let you know how they work out.
