DIY Omni-mic (Compensation involved) - Electronic Circuits Projects Diagrams Free

DonnyTen · 23rd July 2008, 01:54 AM

Hi! Thank Goodness for Google! I think this is an appropriate place for my concern to be expressed. I'm Donny!

I was browsing the net some time go on tutorials on how to build a condenser and this link caught my attention.

http://www.prosoundweb.com/recording...mic_16_1.shtml

However, the diagrams are a little ambiguous to me, i have no electronics experience, but i would love to be able to build the mic described in that link. I don't know many people who do this kinda stuff where i live ( the few I've contacted said they were too busy- I'm desperate)

My idea is that, I'm willing to compensate anyone of you who can make a video putting this thing together. The parts are easy to obtain so that shouldn't be a concern to any of you

Please let me know!

Thanks!

Link fixed!

I must say I don't see what the article is really about?, it claims to be making a 'condensor mike' but all it does is wire a simple electret mike (rather crudely) to an XLR.

There's no electronics involved in it really, just soldering a couple of wires.

looks simple but i dont know how to read diagrams.

I think the article and that mic are obsolete.

The mic is still shown in the Digikey catalog, but as non-stock. Minimum order 1k. Good luck getting one.

Fortunately there are other articles featuring current models of electret capsules, and also showing how to properly use phantom power.

Got any of those articles champ?

mneary · 24th July 2008, 03:19 AM

I knew somebody would ask. I'll be back shortly.

[edit:] Probably the best resource for audio circuits is Elliott Sound Products.

A circuit that looks good is: http://sound.westhost.com/project93.htm

Thanks!!!!

Don't forget the grilled cheese sandwiches and the 'tater dip.

Edit: You're back witha link. Thanks!

hey there,

The diagrams/circuit may seem simple but those little panasonic mics are a wonder.... I've used them for recording acoustic guitar, piano, cello and they have such a flat response its silly for the price really... google 'linkwitz mod' for how to improve its handling of higher SPL (volume).

When you become a little more electronics savy you might want to add a small preamp inside the mic enclosure, as close to the mic element as possible, better SNR for longer calbes.

Digikey, Farnell, Mouser, supply the panasonic mic elements...although I think the WM-66A is discontinued. Plenty of alternative ones though, both omni, and uni directional.

Good luck, and happy recording,

Blueteeth
