I donno about the microphoney/electronics questions there, but about the
heatshrink.... i've put heat shrink on countless cables i've made (multicores,
telephone cable, surround sound decoders, power etc) using nothing more but my mums
hair dryer... (well that was till she noticed the grease)

Subject: MD: DIY Microphones
HI all,
I've built a pair of DIY mics for doing a bit of recording with my MD. I
used a pair of very cheap Electret Condenser Mic Capsules that were so tin
that I needed a magnifying glass to see when I was soldering the wires on.
I'm powering them from a very basic battery box which uses a dead simple 1
resistor, 1 electrolytic capacitor configuration with a power supply (Taken
from the Maplin catalogue and the same as I've seen in the DATHeads FAQ).
Ok, here's my questions:
I know that by increasing the value of the capacitor I can reduce the bass,
but is there a way to boost the treble slightly?
The mic spec. states a power supply range of between 1V and 10V, with 4.5V
being the "optimum supply". What difference will runnig the mics on this
voltage make, as I am currently using a 9V cell. ?
Final Q, just in case somebody knows... Is there a way to shrink heat shrink
tubing without a hot-air gun? I want to make a stick-mic for my MD and would
like to encase the capsule and leads, but don't have a hot-air gun
(hairdryer wont be hot enough I'm sure!).
Thanks :o)
Magic
