Deep Grooves Mastering - Project Bladerunner

Cheers !

It is hard to make comparisons at the moment. Once I have an official Version 1 of the production model, qualitative and quantitative comparisons will be made with other heads.

[dimi751]

You really can't compare the vinylrecorder head, to a cutting head that has been designed from scratch, coils magnets feedback coils.

From what I read in this forum The vinylrecorder head is made from off shelf tweeter not designed from ground up so comparing this head to bladerunner would not be a good comparison.

I would compare bladerunner to Caruso or the Neumann heads and obviously not the abs version bladerunner the final metal version the best of the best version.

Looks promising can't wait for the sound bites to be released by opcode.

Efficiency testing. Undeniable and quantitative analysis.

This looks interesting I'm assuming your measure the vibration I'm probly using the wrong word it looks like -1 is this a good result Todd ?

Dear blade runner

I miss your posts please reply ! Ha ha

How's this project going ?

[opcode66]

I took time to build a prototype that uses my new transducer design. I might as well say it. I am no longer doing moving coil transducers. I'm sure others are going to rush to copy this innovation. And, yes, it is an innovation because no other cutterhead has ever been made this way before. It has taken a bit longer to get to my next video because I've made such drastic changes to the internals. I even had to make a new winding rod to make coils. Everything changed. Though it looks very similar on the outside. Under the skin, not so much.

I also created a feedback testbed for the new style of transducer, as you see in the image below.

I've also been working on a job search. So, this has been moved to a lower priority currently.

Thanks for you ongoing interest!

Here you see Bladerunner 1.D with the old transducers and Bladerunner 1.E with the new ones.

Man you've been busy wow

I think blade runner is going to be huge success!

Cool photos I can see the difference in designs from the old to the new head. And good to see you using a metal vacuum tube !

hi TODD.
is this feedback cutterhead?!
this is awesome.keep cool this project.
i can't wait cutting with this cutterhead.
thanks.

[opcode66]

I am close to completing feedback, yes.

[dimi751]

Just wait till he makes it in metal version then you will drooling ha ha

Double Video Post!

The first video demonstrates the extremely flat response of my new dynamic transducer design. This is brand new for cutterheads. No one has ever made transducer like this before for the purposes of cutting records. It is not moving coil. I also demonstrate the response of a Feedback version of the new transducer. The results are impressive.

Bladerunner 1.E - Feedback & Response Curve

This video demonstrates playback of music via the new transducer design. It sounds brilliant. I think you will be shocked.

Bladerunner 1.E Update

This is so awesome, It's also cool to hear your passion through the video.

I'm not sure I understand, if it's not moving coil how's is it working?
I think it's freaking fantastic, your frequency response...even with the dynamic is so flat... only a tiny dip but it's so much better than the ones I've seen!!
You're really pushing this forward.... that's freaking awesome!

I'm very amazed by your dedication and your skills, you're really innovating and for me as a VR User..... it looks very promising!! Can't wait for you to release your first model.

keep posting videos.... I think I'm not the only one who's freaking excited by that!
great job Todd!!

Very impressive Todd!
And you dialed in the Goldilocks spring design too!

I'm not sure I understand, if it's not moving coil how's is it working?

Moving magnet design.

The coil is stationary [fixed to the non-moving structure] and the magnet is on the moving portion of the transducer. Considering the small neodymium magnets are light enough to incorporate into the moving mass, it makes a lot of sense. In Todd's case, the coils appropriate for the design probably weigh more than these little magnets so switching their 'position' is a good way to work it out. With moving magnet systems, you no longer have to worry about the coil's weight [e.i. wire gauge & length] because they are no longer a factor of the moving mass!

[opcode66]

Thanks so much for the positive words of encouragement!

It is not moving coil. I am sort of reluctant to say much more at the moment. Once Bladerunner is finished and people actually have copies of it, I'm positive somebody will post a teardown of one of them. At that point all will be revealed

But, I don't really want to pull the curtain back myself yet. It is, however, something that has not been done before which is exciting.

[dimi751]

Fantastic work Todd !

I get excited everytime I see an update for blade runner. Now with the new designs perfected it looks like your on the home stretch.

Great work as usual Todd thanks for sharing !

Bladerunner 1.F Build

[dimi751]

Very nice Todd !

I always wonder how you getting your
3d prints to look so smooth and detailed
Blade runner is looking good !

[opcode66]

Many individual parts. Each lart has gone through many changes. Most have been tweaked 50 or more times. Many parts are a combination of ideal configuration as well as printability. You can't print anything. You have to keep in mind the limitations of 3d printing while making these parts. Overall, I think things are really coming together. I am now nit only finalizing the design, but I'm also gearing up for metal by replacing glue to hold parts together with screws.
