How to make a microphone using an RE-254 motor?

As You might know, electric circuitry of a classical ribbon microphone consists of two parts only: the motor itself and a step-up transformer. For normal studio use the third required component is a generic male XLR plug. Just solder these three parts together (5 - 6 solder points only) and you've got a working and ready to use ribbon microphone assembly!

Another task for your DIY creativity is a body. The best choice is a non-magnetic metal, like brass of stainless steel, as they have good screening properties, but many people have used plastic pipe for this purpose with excellent results. Some used bodies of old non-working ribbon mics. You can refer to the technical drawing of the motor to make sure it fits.

You can also use a dedicated modern-ribbon-style slim body of our own design and production.

Is it really that simple?

Yes! Check out the photo of a full working assembly made from an old RE-154 DIY ribbon motor with a plastic frame (now discontinued) and a generic output transformer below. Such assemblies are solid enough for most studio applications when soldered carefully. I have used such plain assemblies for recording by hanging the motor on a mic stand with a piece of wire before I designed the body.

Is it safe to ship?

Yes! The motor ships packed in cardboard and tightly wrapped in a bumble wrap cocoon to avoid the possible air motion around the ribbon. I have been shipping the assembled ribbon mic motors since 2010 and I can assure you that the possibility of shipping damage is extremely low.
