In imitation of my neon projects,... sound generation by an oscillator by means
of high voltage discharges.
I have taken up the following diy project .This is the plasma disk synth
controller.
Now it goes with these, or synth head [filter or osc or control input], or
sounds will arouse oscillator such as my neon. Now I know that on the anode a
very high voltage comes there stand. Therefore then but measured, to prevent
damages to my meters I have not seen that there, without touching glass the
plate this way already a field/scatters tension is of 10 up to 50 volts of
alternate current power. See the red mullet timing eaters and the duspol. If one
negative of the red mullet timing eaters to ground the leg and the plus fixed
how with my hand, and with my other hand/finger plasma touches disk. .gif the
red mullet timing eaters 50 up to 200 volts alternate current power. The tension
of lower part disk varied 50 volts to upper part disk 200 volts. The high
tensions are innocently by the very low capacity, but… nice are to solicit to do
according to me.
Maybe of it still metal a disk must on the edge or that aluminum introduces
tape and these to the ground/ground lay to get nevertheless an impact. I think
that there with only the finger on the plate not enough tension is aroused. I
think that I of it nevertheless make universal controller. With a standard
termination of 0~10 volts or 0~15 volts. To use generator these as sounds
nevertheless find I it what dangerous. There thousands volt on that anode
stands. There has been measured that below the disk it lowest tension is
aroused, and on top of the most. This become higher therefore measurable if you
concern with a finger from bottom to top the disk. Of course comes there
reasonable what chaos if you touch these without ground/ground. But with 1 point
to the ground, and whole all of a sudden ingot is. Therefore I think of metal a
ring for glass the disk. Maybe in sectors, The random use of it is something to
keep.
Firstly a warning .
At this project, high voltages are used. Keep it all secure and think twice what
you do, do not underestimate the dangers.

Many years ago ,i get a couple of neon light bulbs. These were of
neon divider somewhere from beginning 1950s previous century out of a old
electric organ. The standard idea of me with this projects , is that it must be simple
to make, cheap
and with the most of impact. With the neon oscillator you can create a saw pulse,
and can be stepped down in tone , and can modulate as a primitive lfo. The basis principle
has been based on neon relaxation oscillator. The termination is on line level
and therefore ordinary on an amplifier/blender or fx to connect. The idea has
been based on neon relaxation oscillator.
Above the feeding with 100 a 110 volts output. Common placed to dc voltage
and capacitance r1 for the circuit at discharge. Differently the oscillator works
still or what has, also already you the plug. The basis oscillator
diagram is in fact as an example. These do good, however, but really nice
freak are possible you not. The standard oscillator is therefore the nicer
version. These have to 2 neon vary candle ends and balance corrector here
between. R3 is the frequency. Switch beside c1 the condenser is in fact
optional. You can therefore also ordinary 1 of both points aphtha barges. But,
thus the nicer are, and it is certainly audible. Also the switch is a beginning
point for my next diagram [with 8 neon lamps/oscillators]
Extra neon lamp, dotted reflected, gives an extra thick sound. C2 simple lfo
[have been also dotted reflected] these modulate nicely the sound. condenser
between 0.5 uF and 2 uF.Bigger value are lower lfo frequency. C1 is the basis
frequency. How larger the value, how lower the sound. Itself experiments
therefore given up between the 2 values. R2 of 100 k ohm not experiments.
Always also a condenser C1 uses, you does not want, as it happens, that there
tension comes on your audio mixer etc. And of course the line/audio uses transformator.
A beautiful example is my Hexillator, these possibly work with 6 neon lamps in a
circle and can as an oscillator or modulator be used.
At visit to the local recycle shop, I spotted a siel dk70 for 15 euro. In the
first impression I did not know that cb-set there and stood on buy
keyboard/organ. Mark of adsr and dco brought me on the idea that it nevertheless
synth had being. At home once tried and after what maintenance to carbon reviews
membraam who it did not do, and what small other things do good, these it. The
moog filter mod for the korg poly800 do it also on the dk 70. The range is this
way already larger than those mod of poly800. Therefore I have only establish
pot meters to replace by ordinary pot meters. There is therefore no extra
tension there on put. The filter/resonance regulation goes of terrible mat and
decently to total resonate overdrive[bleep]. Right therefore to the slayer
mod, but improves regulable. The gain of normal to reasonable transistor
distortion I have to also still a switch beside of the have been made the depth
completely and integrate onion. Therefore not with the moment switch
which sits standard in the cupboard. [need you not always by that rotten menu to
wrestle.]. Therefore on that 2 wires simply on/off switch.
A time suffered I for little has tapped casio mt750 at local ring course on the
head. This is a rather vast keyboard with mini switches. [pcm synthesis and
minimum synthesis possibilities ]. I him has switches stripped therefore brutal
of its, and made being appropriate to build him in nice box. There a type of
ringmodator in amplifier circuit, and simple germanium diode distortion sit.

The idea had I already 20 years, but now must it of it at last come. I hope
that I turn there each what to can do, I have, as it happens, also still what
other diy stuff and repairing lie. I try my diy stuff always this way cheap
possible, and make components from other piece equipment at recicle. Moreover,
exactly standing several diy springreverb projects where I can do an idea of on.
The springreverb become long approximately a meter, and I use a beautiful sewer
tube from my bathroom rebuilding. Cleaned of course, however, firstly. Both
sides use I p.v.c propeller capsule. As a resounding feather I use metal slinky
feather [toy for the kids] of 3 euro. For the drivers and element I use maybe
some old loudspeakers are possible, but that still what differently become. To
the end of the feather I must still what to consider to bring these on tension.
On I exactly saw already 2 ways to the feather. 1 type the feather has been
assembled to the cones of the loudspeaker, the other type sits the feather
around the loudspeaker. Also, the tube must be placed vertically.
If one places the tube horizontally, the feather bends, and touches the lower
part. There also still [small] a preamplifier for mic/element and an end
amplifier for loudspeaker must.
I was busy with developing a minimalistic filter which works on line level.
This had to work creatively, and not special for studio. But it must work behind a synthesizer or
any sound source. Now I am there according to me
reasonable in successful. But this schematics use of 1 transistor of bc547 the
type [but each npn do it according to me, also germanium]. And the hand full
capacitances and ceramic condensers costs at the most but to a couple euro.
The sound what ends up there is very nice. More L.P.F - heavily parametric -
wah like. With regulable resonance in neutrally score. But I have added also
still 3 pole to a switch with neutral middle class to let sound to the filter
in steps sordid. Regulable filter with distortion/overdrive. This switch can
replace of course to become by each random switch. Moreover almost each
component is, however, at experiments by a another type. [R7 please not too
much]. Feeding is not also critical, is possible even up to 15 volts. I have to
try coordinate the components carefully, but the result can someone,
differently, however, something deviate of course at. It is even for electronics beginners, on a bit [islands] prints. Easily to build in
plasic/metal case
or bend synth project, or as a stub box. Each sterile digital synth become this
way a bit more.
Electret microphone to normal microphone converter.
Here is small easy and cheap schematics of a electret microphone to normal microphone
level output. Electret microphone are frequently used at p.c/computer
microphones, and headset. These headsets are light, cheap and of reasonable
quality for vocoder etc. But for a headset with possible vocoder to use,
it must there therefore what adaptations to be made. This is my electret/microphone
converter. Power feeding is possible with a 9 volt battery , or a small
dc power supply. Below at the schematic a connection/mini jacket diagram for a p.c microphone
Simple overdrive/distortion
Before there responses come under the motto WTF that cannot
nevertheless work. It works therefore… and also still nice. This therefore my 1
component distortion is. There but 1 germanium diode are used and if necessary 1
pot meter to regulate the impact. The most of overdrive's which you can buy on
this principle have been also based, but generally still voorversterkertje sit.
But synth do not have meeastal already amp to border… therefore at these need it
therefore.
The germanium diode are possible being, possibly of the oa serial oa 95. Easily
behind synth to place or at the send/return. Or behind 1 canal of a playing the
drums computer. At overdrive/distortion diagram a modern silicon diode does not
work moreover. also do not try… it works really not therefore it must real of a
type germanium being, these is arrive moreover still normal. These give achtige
overdrive to a tube. Silicon have a higher threshold tension then of the type of
germanium. If one wants one can as a matter of fact afsluitweerstandje to mass
behind the thing put (something between 100k and 1M the ohm) differently are the
functioning of whole rather dependent on the ingangsinpedantie. of what hangs,
but….a bit onvoorspelbaarheid is sometimes also nice. These germanium
diode/transistor are nowadays used much which boutique jet ear pedals. The
pedaaltje /stompbox [read expensive] what more exclusively to make.
These distortion work most beautiful with monofone indicators. With a polyphonic
indicator it becomes already fast very sordid. Or you must find that natural
leuker. The extra buds on the kastje are of a passive filter.
My passive Freakatron ring modulator standard has been built from impedance
linetrafo's Lm44 and the germanium diode's oa95. But I have made up 2 switchable
options with diode's. I have trafo's try of prim 200 ohm/sec 100 ohm and between
prim 600 ohm /sec 300 ohm. These switchable diode's stand in opposite pole with
the ordinary diode. Now it seems that simply these the full indicator lets
through, but it is partly the case. The diode has, as it happens, a threshold
tension, and lets through therefore above certain level just indicator.
Therefore nice nevertheless to obtain others results at freaken and. Also at the
entrance and carrier input a pot meter has been placed [10k-100k is due to
strong indicator]. This pot meter regulates therefore the input independently of
the synthesizer pot meter. Output simply to the mixer or fx. Moreover, instead
of the synth in the carrier can use you also simple tonegenerator/vco. Moan to
use a complete synthesizer for that. A simple sine or other waveform does than
complex the path more often better. In the higher frequencies one the typical
ringmod hear bells. Also still extra switch have been made in. To switch between
the entrance and the carrier. I are, as it happens, from time to time best,
however, lazy, and plug are each time irritating. Therefore now there is change
gear more still something with that switch simply, and this way too then
nevertheless obtains than when you to the plugs would have let sit.
This project is about circuit bending of a Kawai K1m synthesizer desktop module.
This synthesizer modules is arrive nowadays for a little money.
But the real time edit possibilities are a bit limited.
The joystick is of course quite nice.
Therefore these synthesizer go's under the knife.
But there is in fact nothing find on Internet how to bend this synthesizer and
how to do, such as schematics and pictures .
So i must do the dirty job.
But at the k1m it is quite simple because all bend possibilities, and that's
much there to bend , sits around one I.C .
And that i.c stand on the photograph and named Kawai p106 md8w
In fact you can combine each pole with another pole of this i.c.
also multiple connections is possible.
The only poles what you cannot connect with others be the + and - [pole 15
en16]
This blows up the i.c , so bewared !!!!!
And I think that it is not easy to replace this item.
left of that i.c if that with each other put through you is a type of foot like
at an organ. From 20Hz up to 20kHz
To the right of that i.c sit treble, noise, l.f.o, distortion, pwm, and a type
of sample Frequency.
At the Left I put 2 push buttons and 2 switches , which by means of the
breadboard free be to be appropriate.
Everything do of course to wish, and end up there nice sounds.
This project is not difficult but if you have doubts about this … do not start
this project!!!!
A couple switches is also enough , if you know which contacts and patches gives
you the right sounds.
But in this way of course ,you get the most of possibilities, and that's much
with the breadboard.
Now, my kawai K1m circuitbend synthesizer looks like a minimodular.
Cymbal plate reverb
This is my diy plate reverb, which are made with cymbal of a playing
the drums couple. Advantage of cymbal is, which these right sounds already well
by welded and hammered metal. At the lightest contact these will resonate
already. Also the surface of these can a piece than the old plate reverbs
smaller remain therefore which this way already a couple square meters measures.
And to the weight lift you an hernia. Cymbal have easy mounted in the middle , and
floating have been hung. Under the cymbal a large plate mdf with a large breach
sits. Here you can place elements/mics therefore by means of the back
easily. And in and terminations sit. The cupboard has been painted in dark
mahogany. And the front plate is detachable nevertheless a beautiful bit have
art work to the wall.
Here I describe my diy project of the FAT-ASS active
transistor overdrive. This overdrive works on line level, but because the high
gain ,It has a large
range. Universal therefore ..... Now is
my put in, that these for the " few electronics n00bs" also simple must make be.
With going components, cheap and not many components. Now this diagram is in
fact not terrible spectacular, because there are used but 1 actively component
[amplifier staircase] in the form of NPN transistor. This is therefore basis
electronics. Also the tone regulation, the right pot meter of 10k and 100nF the
ceramic condenser is optionally, but too in fact nice there not use.
Nicest thing about this schematics is that the components and
feeding are not terrible critical. 6 up to 12 volts of DC power do it [also pen
valleys feedings] Capacitances and condensers… The value is not critical,
Transistor is a tale separate. These do not have be of the NPN type… further
determine it. A cheap silicon bc547 does it… but also beautiful germanium type
for cool vintage sound. Therefore if you old germanium have transistor,
simply do I can imagine myself that one can 2 transistors of several types
change gear with double switch, and this option will build. My overdrive box
has, of outside interchangeable transistor on a transistor a foot. Therefore
awful nicely for experimental purposes , and is possibly simple of outside
finished contactable .Still just as a test elaboration used I 3 different
transistors at the box. A standard BC547 silicon A former silicon/silicon BF242a
An old 127 Germanium Bc547 has more high and the sound is what sharper than the
other two Bf242a is what rounder and less sharp. Ac127 is still rounder and will
to fail more a sound. The strengthening factor [HFE] of the transistor is of
course also decisive for consonance. I have there just as a couple of the same
type [bc547] tested. I have seen….they are not critical, of 125 to 475 I have
moreover gone myself for germanium type.
Last weekend i messed around with a reverb tank.
And the large disadvantage of these things is, which they are in fact entirely
passive, and therefore for/after amplifying is necessary to work.
I had already searched in books and the Internet for a simple universal schematic.
In the books stand frequently solicit of that basis with general values which
you yourself must count the Internet from, and not this way beautiful
universally and minimalistic such as I have made this diy project.
Therefore. .what I here now mail does not exist in fact already, however. . also
this way beautiful completely. [it is basis electronics]
Nicely universal pre-amp/ booster therefore. Simply put it for or after a piece gear.
Also nice as a stompbox fx for a [bass]guitar .For amplifying of reverb tank or ring modulator… your own imagination is the
limit.
Or simply for an power amplifier .sounds well clean.
The price of the whole diy project is proximally not more than 3 euro.
The upper diagram is the final, therefore good version.
The bottom diagram works also good, but is more if basis/example version has
thought with gain regulation these capacitances also no [100k] parallel
concerning the entrance and termination for possible condensers at discharge
[pop noise]… volume must regulate on the piece gear.
The npn transistor are again not critical, you can use any type.
I have try standard npn silicon bc547 and this sounds good with it.
Amplifies 4x up to 10x.
Also germanium types can be used for a smattering luxuriously and
vintage sound.

smashotronics™ compressor/Limiter
This is a minimalistic compressor/limiter that I have developed. This thing works on
line audio level, and is purely for creatively use , not special for in the studio .Place it behind a synthesizer or
a sound source. Now I am again reasonable successful in creating The smashotronics™
compressor/limiter.
It is even for electronics beginners cheap and easy to make .Easily to build in
plastic/metal case or bend synth project .But the whole thing works with 1 active element, as it happens, normal npn
transistor. For the transistor what can be used [such as bc547] If you want this
project somewhat luxuriated ? ,use a germanium type transistor . The diode's d2 and d3 are the passive limiter part.
For more limiting ,put some diodes in serial with d2 and d3.The complete diagram is not terrible critically, and
any component can chance with another type. .One side of potentiometer R8 is possible with 1 leg for
the condenser C1 [is now after] for
real true-bypass a regulation. The whole thing works with 9V~12V dc voltage.
It is even for electronics beginners cheap and easy to make, on a bit [islands]
PCB.
Easily to build in a plastic, metal case or bend synth project, also nice as a stomp box.
Works on synthesizer line level, but also well behind a guitar.
The whole thing functions with 1 active component, a normal npn
transistor.
For this each transistor can be used [such as bc547]
You want it what luxury ?, germanium type is a nice variant.
Switch S1 and diode D4 are optional for still a more dramatic impact.
