This was pleasantly educational. Thanks!

Why would you want to have two capsules sticked back to back, this would pickup noise from the rear side. Maybe this is not for solo.

1:42 But where can such piezos be found?

Did you mention what ohm resistance/impedance the box output is?

That sounds great! Your Alice mics really deliver the goods on everything.

Can you explain why the crossover cable please (another source suggests a straight TRS cable would do)? As the F8n pro has a BNC connection I assume an BNC to female TRS adapter is needed, then a crossover cable? Thanks in advance.

great vid! elementary question probably, but are the side capsules in stereo? can't really tell even with headphones as the snapping overlaps.

Hi, great instruction! I am about to make the diving version of it. However, I cannot find the Sony PCM-A10 in Europe... And importing from US will double the price... Are there any other small but high-quality recorders that you can recommend? Thanks!

I wonder if this could pick up faint refrigerant luaks?

Absolutely fascinating video. I wondered if I could encase an old cardioid condenser mic. I don`t use it and thought it might do. Is this possible and effective? It`s an Audio Technica AT2020.

I'm late to this video - thank you. QUESTION - I have an F8n. If I get an F8N PRO - 2 slightly different models / would / should this method work?

Awesome instruction, thx. Tried to build it and I get quite some noise in the signal. How can I reduce it? Has it something to do with insulation of the capsule or the components at the male XLR?

that is amazing quality - I've started ordering parts to build my own now - thanks

Hi! Does this mic build work in high spl situations like drums? Specially as a room mic setup, I like my room miking in M/S. And if you could suggest an even darker sounding capsule for this setup it would be amazing! Thank you!

I wonder if you also experimented with building a diy PCC microphone? I'd like to build one, but I wonder what capsule to get...

this is brilliant. Would be cool to squeeze the circuit onto a round PCB that doubles as the to end-cap.

I was just curious if you were going to build a mic for voiceover which capsule would you pair with the alice circuit? I am probably going to go with the JLI Electronics capsules and I was thinking of doing the TSC 1 capsule but wasnt sure. I see they have the CK 12, RK 47, and 86U. Do you think it would be worth it to go for any of these over the TSC 1? Or even just go cheaper with the 2555BXZ3 and not even worry about the polarization board. I am just trying to weigh my options before starting the build. I know its different for everybody so I just wanted to ask if it were up to you and you were doing the build is it worth the extra money to upgrade from the TSC 1 or even the 2555BXZ3 to those more expensive capsules for voiceover? Can't thank you enough for all of these great videos.

I whould 3D printed a spacer/spine to hold two pzt tubes wired as a balanced input, 3D printed the molds in PLA. Then I whould have applied a heatshrink tube over the spine with the tubes on, and a shielded heatshrink tube on top with a bare wire between the two heatshrink tubes. Shielded heatshrink tubes has a electric conductive inner surface. Do a overcast with low viscousity epoxy of the whole ordeal. Of course one needs a suitable buffer/impedance circuit.

I have successfully used marine silicone to fill containers with piezoelectric elements.

amazing just amazing

Wow, such a good singer! Compliments for Doug Adams 👏👏👏... and also a very good recording (-equipment)... unbelieveable you build it by your own...

Impressing

I saw some of your Videos here in Germany. I will start with fieldrecording, and already did some voiceover on my channel with a comercial Microphone. I am very impressed of your own build and decided to do it also. Your way of showing the "how to" is outstanding. Thank you very much for sharing it; go on with it, plese. ... getting goose bumps on hear the singer... Wow

Would it be possible to wire a multi-position switch to select which capsules work? With a switch one could select only the single middle cardioid, the dual side, or all three in the MS layout? I'm assuming this would require a dual channel board so the mid could be on Channel 1, and the two sides on Channel 2. Great video and build!

Hello sir Can I get that Gerber file of the PCB?

I built the 3.5 mm version for the Rode Adapter - it gives poor highs - then I built 2 P48 versions with 10µF and 68k, they work like a charm, I added insulator and then covered the insulated capsule with aluminium foil covering this again with shrinking isolator. Sound on the P48 version is much much better. Works good on Zoom F3 and Arturia Minifuse. Warning, the solder pads are easily ripping off the capsule. It happended to me multiple times. The capsule gets unusable then. Handle like an raw egg. No pulling at the wires at all!!!!!

Can capsules with electrical connections on both sides (like the rk 47) be hooked up in single channel for cardioid pattern only if you just don't hook up the back side or do they still require dual channel boards?

Remember when mixing to go around the sides of the cup, like you're trying to get the last bit of peanut butter out of the jar. Then when pouring, try to pour from the center (like, the main flow should be from the bulk liquid, not from the walls......its hard to explain if you're not familiar with pouring materials......youll see what I mean after a few times pouring your casts), these tricks will keep from getting unmixed sticky half kicked if at all goo in your molds. Remember to get the bottom of the cup too. If there are worrisome bubbles, try to pour in a thin ribbon or a very narrow string (but dont let it break!!! keep it a solid streamer otherwise drips will grab more bubbles when they hit the surface), the thin membrane over the lip plus the shear in the flow should push most bubbles out. Also, cheap and easy releases are hairspray, clear coat, and/or regular, no frills or fluff, Dawn dish soap. Dawn is magic, itll get silicon to kick, and is a billion times cheaper than the recommended hexane and paraffin wax release. Particularly in California..... oh, and especially if using smooth-on resin kits; if you're having a problem with your resin CONTACT THEM FOR ADVICE!!! They are serious about their products (because A LOT of industry hinges upon their products working as advertised and instructed), and they are turbo nerds about the chemistry. If they have a bad batch, or could clarify their instructions better, theyll want to know about it. So, if anyone uses any smooth-on product and its not quite performing as expected, contact them. They like hearing how their products are performing!

Could I use this cable to send stereo audio over a 5pin DMX 10m cable run?

For the capacitors are they 22nf or .22nf because in the diagram you have it says .22nf but then you say 22nf so which is it?

Do you know what the power draw on these is?

Listened to this on my studio monitors... heard EVERYTHING. and it was absolutely crispy!!!! This would make a bad ass room mic and a mic for sound grabbing outside!

Well now I want a pair of these and a pair of 5 gallon buckets to take to band practice!

Just received the Piezo cylinder and the pre-amp pcb. Cable and connector next. I'll airspace the element center as suggested and add a ground stub. I'm landlocked here, but one of things I'll be testing is to lower it into a dug well and see and many seismic signals might be coupled in from the surrounding ground. Another use will be as a Contact Mic for various things. Anything else I need to know before the actual build?

When I was in HS, I went to a tech school class: Electronics. A lot of the students went on to do soldering of electronics for military applications; so they taught us about soldering rather extensively. The instructor told us never melt solder on a joint, let it cool, and re-heat it to connect the wire. He said it causes cold solder joints. Better to use a "third hand" tool, and heat the wire and the solder together; so the rosin will properly coat the joint without getting cooked away.

How did you calculate 100kHz oscillation?

Is the STL/STEP file for the capsule holder from Build #2 available online anywhere? I'd like to make one of these but don't need (or want) the suspension ball holder.

that intro get you a dislike, i hate asmr and whisper but your video is good just the intro.

Reference 10:30 ..... were you able to strip the epoxy off the ones you got wrong? Looking at it it seems like a dremel could possibly salvage the printed circuit board.

I built two! Thank you so much for the work you put into making great instructions and working with a good supplier (JLI).

Can I assume that the P48 version will work just fine with 12v or 24v (rather than 48v) phantom power for those devices that can deliver it? Having a Zenner drop 48v to 12v worries me.

16:21 ...... Frying bacon, haven't heard them lil buggers in about 48 years! LOL

Great documentation and set up. Thank you! I picked up a couple and am in the process of building. The TSC-2 capsules that I received don't have the backplane wire attached (just the front and back diaphragm wires). It did include a separate (unattached) blue wire with a small eye ring that I presume is supposed to take its place. Should this wire be installed with the mounting screw (making electrical contact with the side of the capsule)?

Clever! I was looking last night and thinking about doing essentially the same build but using the Oball instead. There is something so Tom Bodet about your voice that I keep thinking about you ending the videos with "we'll leave the lights on for you".

Thank you. This helped me sync up my f8n pro and f6

The snorkeling audio sounded awesome through my studio monitors. Another great build.

Thanks again Jules for this. Now I'm off to build another pair of hydrophones, and look for a VU T-shirt.

If only I waited another week! I just built my first pair of your Hydrophones last week, but I didn't know if I needed to cap the ends of the piezo. That's ok though, they still sound great! It would be awesome if you shared the sound files from your initial test, that way we could drop them into our DAWs to compare the previous version to the new version! Thanks!

Nice. How deep have they been?
