New HV generator!

[Ray (Flock Man)]

Soon I'll be testing out the new Negative Ion Generator from Electronic Goldmine (well as soon as it arrives).

It's a 12 volt DC in and 15kV out so it should pack a punch for flocking.

I'll post how everything turns out.

Stay tuned!

It came in and the initial wiring testing using a 9 volt battery first- I found the wires go as follows:

The red is input 12volt positive
small Black input ground/earth

Green ground to the ground plate (for the test I just taped it to a piece of aluminum foil)

Large black is the 15 kV out (this wire has markings that say 20kV meaning the shielding on it can work up to 20 kV without leaking.)

Even without using an electrode it flocked a test head pretty quickly.

When I get some time I'll install it into some kind or case/ cabinet or maybe into one of my other units that only has a 7kV generator installed.

I bought two so I may try something completely different that's been in my mind for awhile using multiple generators either side by side or over each other. The goal with it being that I may be able to hang a half dozen heads inside at once. I've tried a system for multiple heads before and it failed because it left some areas thin. My thought at the time was that another generator may help work all sides at once... again just thinking as I write. They may just end up working against each other?

Exciting news! So how is this wired up in a flocker with the knob, plate and power jack? The website said to cut off the green wire, would you do that and replace wire for wire the three wire DC unit with it? Or is it a different wiring scheme altogether?

I'm going to order one right now, my tests with the 4kv out unit were disappointing, and I was about to order a 7kv one from amazon.

Well For negative ION's you would cut off the green, but we are going for a static charge (a power source) so, since the black and green are on the same line (-) the small black is used for the input ground and the green grounded to the ground plate.

So The large black (that's marked HV) goes to the electrode (knob)
Green to the ground plate.

Small red and small black are the 12VDC input power source.

Note: at the time of this posting they have a $8 each sale going at electronic goldmine.

I would grab these while they are around because we all know they disappear quickly and end up on ebay for double the money once the demand kicks in.

Much of this does get confusing because we talk of negative ION's and negative grounding. You just have to understand they are two separate things.

So it would connect like the picture.

Oh, I get it now. Thanks!

So my first test turned out great.

BUT!!!

I put the unit together using an old clear plastic Britta filter container. Once I was done I wanted to do a quick test to make sure everything was live before trying some flocking.

I took a screwdriver and touched the electrode and the ground- this should have produced a spark similar to a car spark plug. It did do this, but instead of leaving a gap I just shorted it out and blew the unit. Luckily, I always buy two or more of most things in case I screw something up.

The problem now is finding the time to dismantle everything and connect the second module.

I post this failure because: 1. I know better and 2. It happens and you have to expect it and maybe plan for it.

Oh, and thank you again for your recent donation to the project.

It helps keep the wheels spinning!

All the best to you and yours!!!

Are you still using this version? Does it outperform the 7.5kv version you used previously? I'm looking at building hands-free station instead of the hand held.
