Take no notice of the ‘Know-All’s’ on here!🤦‍♂️ You did an amazing job!👏 Sounds great, that’s what matters, also wood enclosure just about eliminates all body resonance 👍 Brass screen (grounded) will act as magnetic shield! Very impressive!👍👏😘

👌

Great video. Interesting design. Thank you.

Wood and plastic will not protect against magnetic, microwave background and radio frequencies. Many people use three layers of mesh going from thick and dense inside the entire enclosure, with the thicker part closest to exterior and the thinnest part closest to the motor.

Great job on the build! I'm about to attempt building a ribbon mic myself, I'll probably end up 3D printing the body and motor housing as that is what I have the most experience with, and I don't have a CNC machine. Did you have any issues with electromagnetic interference? Most microphones have a metal body that is grounded to the xlr connector to mitigate this issue, but I've never tested a mic without a metal body. I'm thinking about trying to paint the 3d printed body with a conductive paint to act as the EMI shield but I'm not 100% if that will be the best way to go about it or if it's necessary.

A note, you should not be recommending users to parallel two batteries without balancing them first. You will get one battery discharging to charge the other battery, which can be unsafe if the voltage differences are great. If you want to balance two, you should get them to charge as close as possible, and then set up a large resistor between the two. Alternatively, you can use a single larger battery, or use a transfer switch, or manually swap the batteries.

Dark and vibey sound! great work!

I respect to all job and the machines that you are using for making cover for mic. But please (the main job)help me with wire connection and how we connect to transformer???? Other question Is this need to 48 V fantom power also?? Please clear for me.

Excellent build and video. If you re - ribbon a pro mic as I have, you'll find the fine mesh pop and blast cloth is on the the ribbon motor. The felt is too dense. You need a dust filter off a computer fan or similar. Or go the Neumann route and use two or three layers of different size mesh. Finally, ground the mesh - both sides and wrap the transformer in grounded copper foil. That should kill your hum pickup. Ribbon mics need a lot of gain!

Cool project but the mic did not sound great, perhaps you should test it on louder sources like a guitar amp, bass amp, trumpet. there has to be some use to it. Good job though.

Very good build, and a great video too! Thanks 😀 👍

Great Job !

Dead was really cool

lol open source? Yall just bought an ebike kit and spliced 2 power tool batteries together then act like it was some kind of achievement...

Where do you get the "power timer connectors?"

What connectors did you use to connect to the battery and then to the XT60 connector? "power timer contacts"?

so rad! just wished a side view was shown bc it looks so fabulous.

That is one sharp looking microphone! It’s nice to see good quality plywood without voids. I wonder if Boyd’s Gunstocks would sell a small block of their laminate for use in this project. They have some wild color combinations one could use in the construction of the case. I remember seeing some commercial two way radio mikes with a spring style strain relief on the connector. That wold be perfect for use at where the microphone cable comes out of the body. It would mimic some of the older mikes before the invention of plastic or vinyl strain reliefs. There are some companies out there that sell the ribbon motors and transformers for those who don’t want to go the extra mile in making the motor. A good coat of electrical shielding spray on the inside of all of the housing pieces will cut down on electrical interference, just make sure to bond all three pieces together and hook that shield to the ground line of the XLR connector. A strip of copper or brass foil can be used in one corner by a screw to link the shielding spray coated material to the ground line. Just a few thoughts for those interested in a similar project.

your work is awsome

pls tech suport

pls explain transformer .... how many turns

I’m using 56v and 60v batteries on a Bafang 48v motor. The Bafang system will detect an over voltage situation at 61.5v (error code 7H), so some combination of 60v and 58v batteries in parallel tends to keep voltages within acceptable peak charging. 40v Ryobi batteries for lawnmowers are 6aH. The major brands for 56v and 60v batteries are Greenworks, Ego, Echo and Toro. A lot of choices to use here.

Very impressed! This may be a silly question but some very high priced audiophile speakers use ribbons of various sizes for some or all frequencies. How do you determine the optimal size of a ribbon for a microphone to cover the sound spectrum?

Such a beautiful microphone! Thanks for sharing.

Excellent job! The audio level in your video is quite low, so it's not an ideal presentation of your work. Ribbon microphones are known for having a dark sound, so I think it's typical for vocals to use an EQ to boost the high frequencies some. I'm thinking the purple fabric you used to protect the ribbon might not be the best choice - it might be filtering out high frequencies further. The thoughts I had were to replace the fabric with mesh that will catch the puffs of air without altering the sound, replace the wooden stand with a way to attach it to a standard microphone stand, turn up the volume of the audio in your video and use an EQ to make the sound in your video brighter.

Hi All, Can anyone help me modify the files for a Trek 7.2FX commuter bike? I have no idea what I am doing but I do have access to a 3-D printer through our public library. Thank you! Jacob

Made a few in my days, they are fun, you do need very powerful magnets only neodymium will work, aluminum foil is okay but too heavy I use to canabalise old capacitors for the foil, it cost nothing and for the transformer a 6v you get from any old adapter will work, wired reverse of course.

Great Project, AND It's Open Source! Absolutely Amazing Work; If I Make a DIY E-Bike I'll probably use this method.

For a fully self made microphone this isn’t bad sound, I wonder what is giving it such muddled highs

Have you guys ran the bafang with just one ryobi battery? Will the bms in the battery shutdown from the amp draw? Not sure what the max continuous current is on those batteries.

You'll improve by a lot your magnetic field providing a return path between the magnets...👍

So cool, I wish I had these skills & tools! It's a bit dark/muted, perhaps in future builds the ribbon should be tensioned more with finer crimps?

I had a neighbor build a similar one. Had similar buzz from it. He ended up painting the inside with guitar shielding paint and it cleared it up. Good job. Looks and sounds great. 👍

Awesome work! but the physics explanation is wrong. it is not the change in magnetic field causing induced voltage. At least not primary and intentionally, ideal the Ribon is in homogeneous find and is not experiencing a significant change in magnetic field strength. The principle here is "'Cutting Field Lines" E=BLv

Wow awesome guys👍🏾👍🏾👍🏾

Fantastic job. I love the extra work you did to make it look good... Most people would have stopped when they had the working mic. :) One minor thing... you used rubber bands to support the mic, but rubber bands can dry out due to evaporation of the volatile compounds in rubber. Have you considered any other materials for that, or are you just planning on replacing them every few months?

Thanks Maya⭐️⭐️⭐️⭐️⭐️ PS haha the foil price!!!!!

Very Clean Install and great instructions!

Easy diy just as long as you have a lazer cutter or 3d printer.

Surprising! I fell into the trap, I waited until the end of the video to hear the result without knowing that from the beginning I was listening to your microphone! Wonderful result by the way. Fraternal greetings from Mexico.

Very cool! It’s great to see other women interested in things like this. Far too few take an interest in building things. And I love how unique and well-designed it is.

You should add some kind of badge to the front. Maybe cut a small shape 1/8” or so thick with your initials or something on it. That would look neat.

The ribbon motor looks cool so I think removing the material behind the screen would be better. You can protect the ribbon by adding a small strip of felt over it. I did that with mine and it works great.

can this ribbon mic connect to sound card 48v phantom power?

Nice project! It seems to have a bit of a roll off in the higher frequency range.

25w/hr per mile!?!? That seems a little on the low side

What a nice job you did and the microphone is very beautiful.

thank you!
