Mini notebook - laptop microphone project 28 February 2006, 06:33
Posted by Orhan in : Geeky Techy Stuff , trackbackI love my laptop but it lacks an onboard microphone. I hate dangling cables around the laptop as well as the hassle to find it and put it on while my internet phones are ringing! So I decided to go ahead and build my mini microphone which I carry all the time, attached to the side of the battery to be used when needed.
What is needed:
1- 1/4″ Stereo phone plug (RadioShack# 274-284, $4.50)
2- Condenser microphone (RadioShack# 270-090, $2.70)
3- Soldering iron
4- Hot glue gun (or you might improvise here)
Procedure:
1- Solder the middle and the tip leads of the stereo phone plug, and solder the positive microphone lead to this connection.
2- Solder the ground lead of the microphone to the ground lead of the phone plug.
3- Test the microphone operation.
4- Carefully fill the gaps and around the soldered connections with hot glue. This will also be the casing of the microphone.
5- Let the melted plastic set, and cool down.
6- Carefully trim the excess portions.
7- Enjoy the mini-microphone!
