sounds like TTC H5 chime

Thank you

You can use only 12 oscillators and then put to the exit of every oscillator divider chip (cd4040b) and you will have many octaves (oscillators must be tuned to highest octave that you need).

Hear it at 6:16.

The cap between gate and source forms a capacitive divider with the 0-500pF cap, and both these together is what forms the tank cap of the LC circuit, the L beeing the coil between drain and the variable cap. Remove the 2-7nF cap and the circuit either won't work at all, or or put up to 1-2kV into the gate as it may try to use the gate capacitance itself in place of the 2-7nF one. Some versions of this circuit also has a shunt capacitor across drain and source of the mosfet, most common value i've seen yet is about 1.5nF, changing this value does also affect tuning. All this is, is just a Class E power amplifier with the tank cap split into two to form the gate feedback, instead of supplying it from a external oscillator/signal source.

Who´s digging out the corpse?! ;) 4093 chaos synth is a fuckin fun toy to play with, even the kids love it. The parents not that much, but who cares, ain´t mine kids. If anyone will read this in future: put a little "open" push button in line with the battery and a little cap (~2-4.7µ) behind the switch on chip + & GND. Everytime you push the button/break the PSU the synth is starving and makes cool drumeffects. If you want to go really crazy set up a LFO (40106, 555 etc) and substitute the button with a switch ic (cd4053 or so). Auto-trigger the beat out of this little *peep*! ;)

What an amazing project. Do you have some kind of schematic diagram of it? I'm trying to do one for my electronic project and I would appreciate this help.

Super useful vid - I have one with one or more shorted windings. The idea of just sanding down the contact area is a great one, it makes sense that any shorts are most likely to be in that area. Thanks for the vid!

Hmm tried it tonight. No dice. Must be the new LED compatible dimmers.

Great sounding radio.

Heyy This is a very good video i found for my project but I m confused that which type of potentiometer is to be used here ?

apply the rcrc filter the sound will be like sine.. And will be much sweet

Good stuff!

I made a eurorack format with this chip, it's really fun to play with. There is a playlist on my page if you're interested.

man that snare sounds fine, but imean like.. if you don't want it, i will gladly take it off your hands : ) i just want to build drum synth circuits....... and they are NOT easy..... they are SIMPLE...... but not easy. nobody has the right shit to make them, the schematics usually look like they've been chewed up by dogs and puked into the worlds worst fax machine. nobody explains anything about connecting these circuits to other circuits, each thing requires bizarre amounts of power to be delivered thru special circuitry that takes AGES to build, might require extinct components....... yah the tone part is simple, but altogether this type of project is like... HARD. its a noobkiller. but yeah thats a cool setup, i like it. i'll check out your other videos too. goodluck on your builds man

Thanks you inspired me

That's cool and all but I wonder if you can do this with 32 transistors instead?

Have u tried making a polyphonic transistor organ yet?

this is very interesting I would like to see if it cach those short wave radios like the ones truckers or police use here in my country , my dad use to have one of those radios when I was little boy and I remember listening to some hospital band was kinda cool , vhf or something like that

Clean sound 👍 do you have schematics?

😂😂 you crazy lol

hi, you stay now in the time? i have experiment of free energy with the plasma ball

Hello, I also have this sampler, unfortunately at the beginning of each recording there is always a “crackling/clicking” I didn't hear that in your recordings. Did you consciously do something against the cracking? Is your module connected to battery or power supply? Thanks in advance Regards

Nice

In my experience, smelling a small amount of ozone on your fingers while playing with the plasma globe is normal... It can maybe replace anti-bacterial wash lol

This technolgy has a practical application for learning musical phrases. There are programs for this if you have the music on a computer,but if you are trying to learn something from an internet site you better have a pretty good ear or a lot of patience. There was a device made for this but it is out of production now i believe. I would like to get that chip and convert mic and speaker out to 1/8" jack and see how it would work.

found a nice blog with the schematic.

This is awesome. How do you make stuff like this?

I’d love to know how you built this

What voltages and current ur using? Would it work on different ones?

There is a bit of noise like a second frequency going on, just like in the original Fesz video. Did you notice it? Did you figure out what causes it?

Hey! Im building this exact same circuit and i'm having some troubles. Its not sensitive enough, even though i have a 2 feet extendable antenna. Is there anyway to increase sensitivity without using an unreasonable antenna length? Note: im testing this with a gas stove sparker. I've also added a 2nd stage amplifier, its just an exact copy of the input RF section using a 2n2222a and just a decoupling cap on its base, emitter and colector resistances are unchanged.

Hi, what's the highest frequency these FET designs can receive?

Very rad!

Very nice! I do notice the short there.

Please, please don't hand hold/chest mount your camera, it's pure vomit vision. ...

moin, wo kaufst du deine Komponenten?

You could actually make some cool microtonal aphex twin style music with this

tesla coil fever, hmm.. sadly, there is no cure, i'm afraid. The symptoms will persist for the remainder of your life.

Great job! Just ordered some of those chips :)

around 0.52 no no don't do that ! you don't want to ground the top of that secondary, that will kill the fun !. Think of the secondary as another part of another tank circuit. That coil is the inductor, and a metal object that you put on top of it is acting as a capacitor...with this piece added it helps the coil to resonate and that is why it is more likely to start spitting out plasma. Attempting to ground it is trying to take too much energy out of the system, and , depending on your setup, could either stop the plasma, or damage your MOSFET....

around 9:16...not quite....2.7 nF capacitor across gate and source is not part of the resonant tank circuit, it's there to lock down the varying capacitance between gate and source and maybe drain to source, they range around 1000 pF and contribute to instability. Might be beneficial to go a bit higher than 2.7 nF.....

If you immerse that variable capacitor in some oil you will be able to get much higher voltages without it arcing over.

Hey bro i am new at sampling but my keyboard broke its a yamaha prs series 510 so do you have any idea on how i could use parts of it to make a new sampler out of it

It sounds really cool. I love the bass drum sound, or whatever you call the one on the right side. Thanks for sharing!!

This is rad! I’ve been considering circuit bending an old Texas Instruments calculator. Any advice?

Hello Dirk

I have a question for this circuit. Does the output coil and the oscillating LC circuit must be tuned at the exact resonant frequency? and is it better/worse or no difference if secondary coil is inside the primary coil like a classical tesla coil?

About the chock.. why shorted the prmry coils..

WHY NO PRESENTATION??? KURWA MAĆ
