This video shows you the various types of static grass applicators available and their capabilities.
At the bottom of this page is a video showing you the assembly process that is covered in this page with text and pictures.
So let’s get started.
Start with the working end. The way it delivers grass determines how good your scenery will be.
A tea strainer is one of the best grass containers to use. Use it as it is or add a cap.
You can also use a mason jar and add different screens. The advantage of a mason jar is that you can keep several filled with the grasses that you are using and just change you jar.
Now we have to get a static charge on the tea strainer.
So we need a static field generator. If you are spending time making a static grass applicator, get something that you know will do what you want. And that is to have your grass standing up without having to use a vacuum cleaner.
.Get something powerful like this 15 kvDC anion generator.
You want to turn your static grass applicator on and off. The switch you use should be one of the plastic type typical of the one pictured here.
You are dealing with 15 K the DC will and you may get feedback if you use a toggle switch with a metal toggle. That feedback can be one heckuva jolt!. Be safe. Stay insulated.
Power? For the anion generator recommended above, 4 to 12 V DC is required. 12 V DC will give the strongest static field. Current rating is really not important. You are not building a transformer. The anion generator does not pass current. It creates a static field. .5 to 1.5 amp capacity of your power supply is sufficient.
Use a discarded gadget charger. Or connect to a power pack. Or to your train layout track. If you use a gadget charger, cut off the wire tip and add banana clips.
So, we have power, a grass container, an anion generator, and the switch.
Now attach solderless connectors to three of the anion generator leads. Connect the fourth to the switch.
Run a short piece of wire from the switch and connect a solderless connector.
Here is where you are now.
Now let’s put all this together in a box. A plastic electrical junction box works great. You can make something else.
Drill some holes and put on female banana clip receptacles.
Drill a hole and install the switch.
If you don’t have the drill the proper size, drill a hole smaller than the switch diameter. Then use a sander on your rotary tool to enlarge the hole. If you do not have a rotary tool, put some abrasive paper in your drill chuck and use it as a sander.
Hook up your wires. To the right is a wiring diagram.
And here is what it looks like in real life.
DO NOT CHECK OUTPUT VOLTAGES OR CURRENT OF ANY NEGATIVE ION GENERATOR! IF YOU DO, YOU WILL BURN IT OUT. The way to test is to make some grass patches. If the grass does not stand up, contact the supplier of your anion generator or us for help.
Use banana clips on the ends of all power supply and container leads.
Make a grounding wire using an alligator clip and a meter or so of wire. Add a banana clip.
Plug in the power supply, grounding wire and tea strainer.
You are ready to go.
Here is the video showing the actual assembly.
