I had previously produced a guide to build a handset to connect to the phone via cable, but then I withdrew after discovering that they had several different connections from other terminals.
With this model eliminates these problems.
This realization is not very simple in some passages, but with a bit of dexterity and patience should be within the reach of most users.

To join the telephone handset to a telephone office, look at this guide.

Step 1:

An old telephone handset.
A Bluetooth headset.
Soldering iron, hot glue and the usual common tools such as drills etc..
<br>Do you think it would be possible to add a ringer circuit to it?
<p>Cool! I am planning to do this with a WWII candlestick microphone. I will probably need to add a seperate earpiece, though.</p>
How do you charge the battery?
In step 13 you can see the female jack to connect the power cable. in my case USB. :)
for a few $$ you could replace the stock battery with a much bigger one and it could go a month or more even with your daughter using without having to be recharged
got mine out of an old portable speaker. cheers for the idea :)
good idea +1 :-)
definitely making this to go along with your office phone instructable :)<br>one thing i dont quite understand though. are you using that ir led as your button ?or is that serving another function?
It serves only as an extension of the button. you can use anything.
ok then great. cheers.
Pretty cool! Have you thought about using Sugru to cover the hole and make it more flush?
He could have used a plastic piece, glued over the hole with a super glue, then sanded down flush. would have worked just fine. <br><br>nice build. <br><br>BR
But by using black sugru, it would match the handset and blend very well.
Ah, smart idea! I dunno why I didn't think of that haha
agreed, could mold the sugru to be used as a protective cover for the jack too.
Nice idea, I had almost the same idea some years ago but to the car hands-free set.
