However I discovered that taking my gloves off and unzipping my jacket pocket to answer my mates calls every 5 minutes can get quite frustrating, and cold. Especially when it turns out not to be my mate but some random talking to his mates on the same channel.
Anyway, long story short, I decided to install a headphone socket so I can hear and respond to my mates without having to remove the radio from my pocket.
Step 1: Crack It Open. (Not Literally).
If you havent got an old PCI modem to destroy you can buy the sockets from Maplin(79p). I'm sure you guys across the pond can pick them up from RadioShack, and DickSmiths if you're Down Under.
Anyway on with the show. Find the screws, mine were under the battery cover and unscrew them. Put them somewhere safe, I know what you're like!
Gently pull the casing away from the electronics being careful not to rip the wires from the loudspeaker.
Step 2: Prepare the Headphone Socket.
I can't say how you'll need to wire up your socket but the pins on mine were paired side by side. Solder a black wire on one and a red on the other for each pair.
Step 3: Connect the Headphone Socket.
You'll need to do some testing (with batteries installed) to ensure the correct circuit is cut off when a headphone is plugged in before soldering in the socket. Otherwise you'll just end up connecting a speaker to headphones and that just won't do!
Once you know which wires go where, solder it all up good 'n' proper. I left the old leads on the loudspeaker as it was easier to just twist them together, solder and heat shrink tube or electrical tape them.
Note: Sorry about the blurred images. They all seem sharp when you're viewing them on a 2" lcd.
Step 4: Preparing the Case.
I measured the height and width of the headphone socket and using a sharp scalpel, marked where I needed to cut a hole.
Clamp the case down and drill, Dremel, cut, saw, melt that hole right out. I chose the Dremel with a router tip. Messy job but soon tidied up with a scalpel. Please note that the electronics are still out of the radio case at this point, Dremel plus PCB equals whole lot of your time wasted.
You are now good to close the radio back up but first I'd stick the batteries in again and make sure it's all kosher. Nothing worse than screwing it all back up only to find out that you're useless and you have to undo it all again.
Step 5: Close Up the Case and Go Snowboarding!
And that, my friends, is it! Now do it all again for your other walkie talkie otherwise your mate will moan. I managed to do the second one in about 20 - 30 minutes.
I hope you enjoyed my first instructable (there I said it, it's my first!). Feel free to comment all you like.
