Care to guess what it is?
Other Circuits
So your existing control circuit will not
handle the load you want to put on it?

This section has circuits you can use to
add power handling capabality to existing
and a few others that may be useful for
your display

The contents of this section are not for
everyone and can even be dangerous.. please
read the disclaimer below before continuing.

Most of what is here is old (but still valid)
at this point in time, I'm no longer updating
these sections, but am keeping them in place
for historical purposes.

all info here is provided as is without warranty of any sort
I can not be held responsible for any problems/damages/injuries/
etc caused by the use or misuse of this info

Warning: read all the following before you continue.

The info on these pages can be DANGEROUS.

Electricity can KILL or INJURE you, be careful and treat it with
full respect.

Electricity can also cause FIRES, again be careful with it.

Never work on any circuit with it turned on or plugged in
If you don't know anything about electronics, don't try to
build these, if you want to learn check with your local
college to see if they offer a class (this is worth doing

Some of these circuits still hold enough of a charge to
cause injury or death even when unplugged

There is no guarantee that these actually will work - build
at your own risk

If you know anyone who has epileptic (or other) seizures,
keep them away from these circuits when on, exposure to
the flickering/flashing could trigger it.

Do not use C7 sized lights with these or any circuit that
uses a SCR or Triac to blink them. C7 sized lights have a
flaw in the design that sometimes causes a short when a
bulb dies, normally this is not a problem, but in this case
it will blow the Triac or SCR. (miniture lights, and C9's
are ok

Do not attempt to control fluorescent lights, with any SCR
control circuit. you will at a minimum burn out the bulbs
quickly, and could cause a fire. If you have a fluorescent
light that is designed to be flashed, it should be ok on a
Triac controled the light's instructions.

Products such as Fluorescent Lights increase the 120volts
input up to 600 or more volts... while 120volts is easily enough
to cause death, this increased voltage is much more dangerous...
it is even more likely to cause serious burns or DEATH. a
Fluorescent Light should be considered ARMED and DANGEROUS
whenever it is on (whether there are bulbs in it or not)
Fluorescent Lights can also hold a charge even after being
unplugged, (especially if there are no bulbs in it).

If the circuit is going to be exposed make sure the case is
weatherprofed. If possible put it in a shed or garage (not
an attic though) and run cords to the lights, this will save
the cost and trouble of weatherprofing.

For the circuits that respond to sound you are going to also
need a place to put a speaker right beside them. A backyard
shed is a good place if it has power, and you can get sound
to it (this keeps the sound 'hidden' - unless for some reason).
you want music playing to the neighborhood)

Some of these circuits can be annoying (part 1)... causing a
slight flicker/dimming throught the entire house. this is
especially true with these 'add-on' circuits, because they
are controlling a heavier load (the more load, the more you
dim your house)

Some of these circuits can be annoying (part 1)... generating
'noise' on the power lines throught your house. this will
show up as static/interferance on TV's and Radios (and that
even includes when listening tape or cd players), as well as
some other electric devices...this is a problem, i'm not sure
what to do about it, but a noise filter may help

To prevent any possible problems Do Not attach these to the
same circuit as your Computer, Stereo, Or TV unless you have
a good line conditioner for it

I did not design any of the circuits here, but I did modify
a few of them to work with standard 120vac

Never overload the control circuit check the wattages page
to get some idea of how much power a set takes

These are only for use with standard 120 volt AC (USA,
Canada, etc.) If you live in a country that uses a
different voltage, do not attempt to use these.
(some can be modified to work with 240v but i won't go
into it here)

Some of these may cause interferance on the TV or Radio.

Computer controls can damage or destroy a computer if not
done correctly

Always have someone double check your work before connecting
power to anything you've worked on.

Electricity and Water do not mix.

Avoid working in any area where flammable products (such as gas/
paint/etc) are stored or used

Do not work with electric items when you are tired, being tired
will only increase the chance of mistakes

Avoid working on electric products if you have consumed any
alcoholic beverages or drugs (medical or otherwise) as these
will impair your ability to concentrate on your work

if you become frustrated while working on something, set it
down and walk away (turn off / unplug any equipment you have

Keep your work area clean and organized. If you work in a room/
area without windows (or work at night) install a automatic backup
light... that way when you blow a circuitbreaker/fuse you will not
be in the dark.

Do not overload Circuits/Extension cords/Lightsets/ Etc

Modifying any electric product WILL VOID any warranty on it

Using any electric product for other than its intended use WILL
VOID any warranty on it

In addition there is a chance you will void your insurance by
using modified or home-built electric items, if that item
causes a problem such as a fire

This is only a partial list of the cautions/dangers there are
many more not listed here (but still apply)

Always remember...
Be safe!
It is not worth risking your life or home over an electric item!

I can not be held responsible for any damage, death, fire,
etc. resulting from the use or misuse of these circuits
