yeah... with most electret capsules, you really have to avoid any kind of physical stress on those tiny solder-pads. It doesn't take much force at all to tear the metal pads off.?
Many thanks for your advice! I think my soldering technique lacks better preparation and more professional execution. Next time I'll be more careful. To avoid thermal damage of the capsule a friend of mine milled a heatsink out of aluminum. Many thanks! I hope it will help!?
Nice bamboo housings!
If one has access to bamboo, making the housing isn't all that difficult.
The housings are made from bamboo roots that I collected from a grove that was cut down at a nearby riverbed two years ago. To remove the oil from the roots and to make it less susceptible to insects and mold, I did a heat treatment and sanded the roots at the ends. That¡¯s why they are looking slightly burned, which I like. The roots are very strong. I drilled a hole the size of the microphone cable on one side and another the size of the capsule on the other. Then I pushed the cable through, soldered the capsule and pulled the capsule slowly back into the prepared hole. Even without gluing, the microphone cable sits quite tight. The capsule is also not glued to the housing for the time being. But I glued the cable ends to the capsule surface, as described in .
Now I'm looking forward to taking some test recordings. :-)
