My DIY electrostatic headphones
I think the most commonly recommended adhesive in this thread -- and the one that I have used successfully -- is Contact Cement. I use Dap Weldwood Contact Cement, seen here, but there may well be other brands selling a similar product depending on your location. AFAIK, this (and more...- OnyxOcelot

My DIY electrostatic headphones
Slightly off topic but I am curious to head how people make the headphone bands. So far, I've only used parts of old headphones, but would like to make my own. I have access to a small sheet metal brake (a type meant for making the chassis of electronic devices), but nothing else in terms of...- OnyxOcelot

Yes, I've made one pair of diaphragms with it. It is VERY easy to use and seems to work relatively well. I don't have a good way of comparing / measuring diaphragm tension, so can't speak to its effectiveness, but I can get the mylar drum tight (so that it has a clear note when tapped)...- OnyxOcelot

Here is my new Mylar stretching rig, in case anyone is interested! Some design details: -- Dowels run through the corners, with springs around the dowels pushing the frame apart. -- Turnbuckles allow me to tension or loosen the frame evenly. -- Each piece of frame that touches Mylar...- OnyxOcelot

Well, from the looks of things, you seem to have figured it out! But, for reference, I use the "Tiny G" post-processor. Synthetos -- the company which made the Arduino G-Shield for GRBL -- also made Tiny G, and they support similar sets of G-Code. ...- OnyxOcelot

Thank you -JFK- ! I would also like to build a similar variable-bias power-supply soon, but need to spend a great deal more time learning about high voltage electronics first! Also, I use Solidworks for CAD, and output .DXF files to Vectric Cut2D...- OnyxOcelot

Hi -JFK- Could you let us know a bit more about the amp you are building? Or show us a schematic? I have built several pairs of ES Headphones for my 'normal' (230V) bias Stax energizer, but would like to build headphones and speakers with a higher bias requirement. I have very...- OnyxOcelot

Yes, I made slots instead of drilling to reduce machining time (I am working on borrowed machine time), but there have been some issues of stator stability -- no resonance yet, but a certain amount of bending as they are fit into the (makeshift) case. Wachara, on this pair of drivers, I...- OnyxOcelot

Hey Folks, Just thought I'd check back in with my latest ES headphone driver build. No grand new ideas here, but I was able to get access to a CNC machine capable of cutting rather accurately, so am pleased with the build quality. I am still having some difficulty finding the best way of...- OnyxOcelot

There is also this book by Roger Sanders called the Electrostatic Loudspeaker Design Cookbook which seems quite expensive, but is probably floating around somewhere in a library or could be found cheaper than Amazon.- OnyxOcelot

Thanks ChinsettaWong! You're definitely right that I just need to start and make a few mistakes! OO- OnyxOcelot

My DIY electrostatic headphones
Hello again all, I am glad as always that this thread continues to be as active and inspirational as it does. My own headphone making studio has been somewhat dormant as other interests and jobs took over my time. Fortunately, I've got some time now to reboot the machinery and see if I...- OnyxOcelot

I figured as much. The slotted stators should have an equal amount of open and conductive area as one with holes. What type of paint do you use? And do you cover them entirely or just the edges where they touch the spacer? The stators are ~ 88 x 76 mm. I would like to make larger ones...- OnyxOcelot

Also, I would like to solicit criticism for this stator design. It has slots rather than holes, and I made it simply to cut down on machining time. On my CNC, it took over 20 mins to cut each stator with holes. With this design, it took less than 10 mins. How might it affect the sound...- OnyxOcelot

My DIY electrostatic headphones
jgazal, do you have a plan for how to coat a diaphram as such? Perhaps a stencil held on top of diaphragm with your coating material sprayed or brushed on through? A hopefully quick question with a long explanation: I put together another set of rectangular drivers yesterday. These have...- OnyxOcelot
