You are holding the iron on the Piezo substrate too long. If the piezo's temperature exceeds the curie temperature threshold for too long, the crystal starts to depolarize, losing its effective travel. This means you are degrading the max amplitude that your piezo will produce, while also degrading frequency response. Maximum time you should ever hold that unregulated soldering iron to that piezo is 2 seconds. Use tons of flux when soldering, I don't see any in the video, but flux will make your life so much better when soldering. It helps remove surface oxidation, spreads heat, and allows the solder to more easily flow into an area. If you don't have flux, get a simple flux pen off amazon. Source: I'm an EE
Hey thanks, that's a great tip. For those who are trying this at home, for sure find a way to use some flux. I didn't have any at the time, but it does make a world of difference. What is the curie temperature in this context? I've never heard of that term before. -Jake
The Currie temperature threshold for piezoelectric materials describes the maximum temperature the material can withstand before its crystal lattice structure starts to depolarize. When they depolarize, their net displacement approaches zero as contraction and expansion of each of the individual structures may be in a random direction. Random orientations entail a net value approaching zero, displacement will cancel out if entropy is allowed to take hold.
Looks like me when I was young fella, wanting to know how stuff works or making stuff work better. Over 40 now and I get chewed out for taking the wife's vacuum apart ! Lol
to get solder to stick to the tricky wires and surfaces, get a tin of flux. use an ultra fine grit buffing cloth or contact paper (after using a lighter like you did) to get remaining coatings off and rough up the surface a little, and then apply a coating of flux, let it sit on the surface for a bit before soldering. it should have created micropits in the metal, allowing solder to fill the pits of the now clean metal, and bind to the area.
sweet. exactly what i needed for my next project. diy, non convential hearing aid. Don't worry my rooms by lab too. but so is the garage and kitchen and living room, backyard and bathroom. So i got a problem. shrug at least it isn't cannibalism
nice video...i think i can use it my project-(audiometer)for bone conduction test. but i have a doubt..can we hear the same frequency as which is generated.
Hi can you help me? i'm trying to add L/R external mics to my cheap bluetooth bc headset. I have cancer in my ear, tinnitus and hearing loss. Normal in ear hearing aids aren't great for me, because i have other stuff goin' on. Due to need i am teaching myself electronics because i'm sure its only a matter of creating the cuircut. This is the first video that isn't just a hack or trying to sell me components. my specialist doctors laugh because they think my idea is impossible, but itsthe only way i can socialize and interact otherwise i'm the deaf guy in the room, lol, my inner ears are good but im deaf because of other stuff (chemo) . Everyone calls me the anomoly, cause 16 years ago they gave me 2 years to live. i have a cheap bluetooth bc headset from ebay that i want to take apart and add external mics that play through bc. help me build an anomoly?

Such a neat video, skill, quality content, no annoying music, crisp

@@JamLabs01 how to use flux though
@@davidbarnes9626 how to use flux sir!?
00:40 GOLD... also my room is the same lol

This is great, I love the new effects.
If I had more sway on social media, I would totally share, but I don't, I am a mere lurker.
sweet.
exactly what i needed for my next project. diy, non convential hearing aid.
Don't worry
my rooms by lab too. but so is the garage and kitchen and living room, backyard and bathroom.
So
i got a problem.
shrug
at least it isn't cannibalism
Awesome video, definitely earned the sub. I agree with John Knitter, you deserve far more subs and recognition
Great idea man
Thanks for sharing
piezoelectrics!
rock on
amazing man
Personally I own moving iron speaker headphones from the 1890s
This was so cool. I'm really inspired.
Hey man, curious question, did you ever got to do the amplifier video?
nice video...i think i can use it my project-(audiometer)for bone conduction test. but i have a doubt..can we hear the same frequency as which is generated.
New sub here. I’m thinking of building something similar.
Buena idea
great video you deserve more subs in my opinion
John Knitter Thanks so much! Tell your friends, new video just out!
If you connect a second piezo crystal to the other ear on the ear buds will it still pass the impedance level to play through both sides?
maybe
i dont know
I want to know how you set up the natural light and why do you have to beat the light ?
How did I not find you sooner?
maybe a bit zooming in on the work and focusing would have been better
Flux in a tin some solder has it inside I'll use the tin flux it has more effect
Thanks buddy
When you play video in 720p but it shows video like 144p and you cant do nothing about it.👍 Nice out of focus.🙂
Awesome 👍
Thanks for this great video. Do you also think its possible to create a similar microphone for recording sounds and signals from the brain?
You could, but it wouldn't be similar.
Did u ever make the audio amplifier video?
Can be use for crystal radio??
subbed , nice video man
Where are the focus bro
i have heard that we can not hear sound from the bone conduction speakers until we touch it somewhere. ??
Nakul Kundra the ones I own have some noise bleed but it's very low.
he you didn't show how and were to solder the wire ..
uuum that's kinda freaky it's like you're talking inside of my head!
but great video!

is this the same tecnology of the headphone aftershokz??
Yeppp
Mike Postle took this idea to the poker ♦️ table after looking at his phone was too risky.
Hm,interesting
subbed...
c:
Dude... How do you not have a million subs?
Work on the focus *dude!*
You have really nice hair
Hi, Are you interested in bone conduction glasses? Our products are expected to be tested by you. If you are interested, please contact me.
so outta focus
