Hello Guys and Girls,

My name is Allison. I'm a college student working as a co-op for EVR and have been working on new high voltage kit for the company. I'm really excited about the kit and wanted to offer a few of you the opportunity for a free kit for your evaluation and testing.

The entire kit is comprised of a cockroft-walton multiplier which is used as a first stage to generate the charging voltage for a marx generator. We had planned on using a flyback power supply for the first stage but found it was more cost effective to use a basic multiplier circuit. The Marx Generator itself is built on a really cool 0.128" thick black PCB board with circular cut-outs for the spark gaps and has brackets to mount on a wooden base. Its 12 stages.

Keep in mind, these are very low power high voltage circuits and are intended for educational use only. So if you're expecting a Marx Generator capable of creating 20 foot arcs . . . well . . . sorry to disapoint you guys!

I'm looking to send at least (5) complete kits out for evaluation. In return, i'd just like to see how well you guys do with them and how long of an arc you can create.

I'm really excited! So please post your names to this thread. I'll send out at least the first five (5) people and possibly more.

Due to shipping costs, i have to keep shipping for US individuals only.

Thanks Guys!

Allison

Very cool looking bit of kit, right down to the cuts to stop creepage. What is the intended input voltage for the CW multiplier? I can guess but I am but a lowly electrician, bannished from the land of engineering ;) I'm in Canada so I'm not looking for a sample, just curious.

Hi Allison, My name is Harrison and I am very interested in trying this out! I think it is so cool that EVR gives the community an opportunity like this to help out and evaluate a product! Id be more than happy to test one out and provide you with feedback to better help your production of the product and other future products that may stem from this smile

interested in testing this on a N2 laser cartridge (marx or CW with triggered spark gap)

Dam, too bad I'm in the UK as I would have loved to have evaluated one of these kits.

We can ship internationally if you do pay the shipping which will be about $20.00.

What would it cost to buy the kit + shipping to Norway/EU?

Any recommended power-supply?
