Fig-8.doc in my FILES directory describes a Fig-8 capsule I designed some 40+ yrs ago for Calrec.? It has sources for 5 & 10 um Aluminised Mylar and other useful info.

Excellent result -- well done! :) I must confess I didn't think I was going to hear something quite that impressive, when I first downloaded your mp3.... If one could create a version with a

Excellent!!!! More microphone Instructables! Best Regards, Jules Ryckebusch

Very interesting!

where do you get this sheet? I bet not all space blankets are the same and this thin.

I have small confession to make... The space blanket I've been using is not 20?m thick as originally assumed. It is actually just 6?m thick! I got hold of a proper micrometer today and was able to

Brilliant!! That sounds much better than any of my home made capsules.

Yes, OT but related, Heathkit once produced a mod to the "Two-er" (and "CB1", "Ten-er" and "Six-er") which uses a Wheatstone bridge composed of two #47 bulbs and two 4.7Ohm resistors to yield a

I believe the only thing this circuit has in common with the subject discussed here is that they both are related to electronics.

Taking on board what has been said about the backplate mass, I've built another capsule with a double PCB backplate. I also played around with another shape: a bowed-in square. Thanks to having two

Hi, I am sorry, maybe I do not understand an idea but, I found something what may replace lamps: Vishay VO1263. Here is a link to the Mr Scott Wurcer article (diyaudio Forum): "*My version of the G =

Buggy whip with 56k modem, and tape backup.. I my very very humble opinion, I agree. ?Think “simpler” would have been better (again, my opinion). ?Maybe the inventor had some goals in mind that

The circuit itself pretty much already existed, as the "phantom power for Radio Shack PZM" design. Very much a stripped-down Shoeps, for electret capsules.? The "Alice" really started when we got

Here is the History: (And I am Sure Scott will correct me if I miss something) Scott hand built mics with this name and a simplified circuit. He named it this because he took photos of it initially

I will try my best to explain, but Scott, Jules, and Homero can probably answer this better than I can. The "Alice" mic was, as I understand it a minimal parts take on the classic SCHOEPS design.

I think the name Alice (in microphones) was created by Scott Helmke. If I remember correctly, it was based on 16mm capsule and a FET circuit. Now I see "Alice" all over in the mic DIY communities.?

Why do you need RD1 and RD2, wouldn't be one RD enough? Same for RS. Would we need a HexInverter or something else for the polarisation Voltage? With the OPA and the Fet and T1 could there be a
