How to create pulsed DC?

[jadaro2600]

Are there any simple methods for creating pulsed DC without expensive equipment?

Howdy jadaro2600,

I just couldn't resist this one.  Two bare pieces of wire touched together intermittently.  Telegraph Key.  Doorbell switch.  Frankenstein's Knife Switch.  Dog chasing a squirrel tethered to a circular run upon which a cam periodically closes a momentary switch.  Frequency is determined by the fatigue level of the dog and disposition of the squirrel.  Hahhahahahahaaahahahahhaaa.....

Seriously, there a bizillion ways to modulate DC power.  Since you are new to Overunity.com lets start with the D14...

Hmmm ... Yes there are 

U need to turn direct current on and off.

Thankyou for your replies;
I  will look at the 555 timer circuits.

I should be more specific though, what about any easy ways to create pulsed DC from preexisting AC?

Hi jadaro2600,

If you know your way around electronics, I would say get a small 75w (about $10 on Ebay) or 100w+ 12v ($20) inverter in an aluminum housing that runs cooler. Rectify the output and you have pulsed DC. You can mod the circuit to make it more reliable and other tweaks are also available online. You can use it to drive magnetic motors more efficiently (except for the Newman design which does not benefit from the pulsed input) or crack water with better results. High voltage precludes a higher safety factor in experiments. Play it safe and protect yourself and others by using a safe working procedures and equipment.

You would get a 160v-170v pulsed DC output cheap.

Hope this helps,
