I have volunteered to moderate this new group. It is a transition from http://groups.yahoo.com/group/MicDIYers/ which was wounded by large quantities of spam. ...
Mac suggests that I shouldn't even bother with posting from the original group and making a mirror of those messages here. It would save me time if we did make...
I recently ran across a microphone capsule that appears to keep its fet a few inches outside of the capsule. If there is no downside to that design I could see...
... That makes sense to me. I think it might be a good idea to just post a notice on the old page from time to time so that people can find this one easily. I...
It's actually very simpel. After taking a look inside a few dynamic microphones, I bougt a dynamic capsule and wired the capsule between hot(2) and cold(3). It...
In "Files"->"Schematics", I've upploaded a PDF describing how to connect a modified Panasonic capsule to a balanced input (or cabel). I've built it myself, but...
... (i.e., ... from ... We got it covered. Macrohenry is control for ownership and he has listed me as a moderator. We both have active the "delete group" key...
This is true, however I have customers that have been specifing that I make them ECM's with no FET's for years. In my customer's applications they are...
We make many kinds of ECM's It's time the WM-60/61 had some competition. If everyone can agree on what such a device ought to be, I'll run some, pass them out...
If there is enough interest in having ECM manufacture a replacement for the WN60/61 capsule. Then how about manufacturing a capsule that could be used in a RF...
... Something with pre-amplifiers maybe? I have some Ole Wolff microphones on desk at moment and testing them for one rather specific applications. As I don't...
... What an interesting offer! Personally I'd be interested in some with larger diaphragms, say 1/2", to increase the SNR above the molecular shot noise and...
the rf mic circuit is floating on the net - it is primarily of the sennheiser 405 mic. i have it on my files but i do not remember where i got it from. i...
... Further thoughts: while the default configuration probably should remain common source, it would be nice if the design had the modification to two wire...
i would like to see a capsule without the fet. that should make it possible for many more design ideas - a low noise fet opamp for instance, bootstrapped,...
For my applications I agree a larger diaphragm of 1/2" would be great and going much larger one starts to worry about condensation and humidity in outdoor...
... Yeah, I'd like them for a DSP based DIY Ambisonic mic and the fig 8 for a M/S mic. For the M/S I could live with back to back cardiods for S but its more...
The BSE's with the NS preamp chip in them are OK for the big volume aps like cell phones. I can put them in ECM's but have to ask myself, why? Eventually NS...
12.7mm is 1/2". We can look at that. We can make anything makeable, HOWEVER 6mm or 9.7mm is what we run all day, every day. That is where it is realtively...
Bob, I couldn't agree with you more about "A collaborative design would be a great inauguration of the new group." I was here a long time ago and dropped out....
OK - the whole point for me is to help people play wih microphone stuff and make their own inexpensive, probably better versions of stupidly expensive ...
This is a fit for something I want to make. I want to make a mic for tracking wildlife. I want to make it so you can hear the faintest, furthest away sounds....
