Static Grass Applicator

I wanted a grass applicator to complete a diorama. I didn’t want to pay top dollar at the local shop, and the cheap ones seem to zap people (That is what happened to my mate).

Tools
• Soldering Iron
• Heat gun
• Wire cutter
• Wire strippers
• Hot glue gun.

Consumables
• Negative Ion Generator (What I used http://oatleyelectronics.com/product_info.php?products_id=915)
• Metal alligator clip
• Heat-shrink tubing (I used 5mm diameter)
• Epoxy glue.
• Sieve wire mesh.
• Plastic container (What I used https://www.kmart.com.au/product/3-pack-500ml-round-containers/158301)
• 9-volt battery.
• 9-volt battery connector.
• 500mm of wire for the grounding wire.
• Push button switch (What I used https://www.jaycar.com.au/black-miniature-pushbutton-spst-momentary-action-125v-1a-rating/p/SP0711)
• Hot glue gun sticks
• Solder

Rough Guide
1. Slide the Negative Ion Generator into Grass Applicator Bottom. Make sure the negative and positive wires are sticking out the top and the -EHT output wire is sticking through the bottom hole. The generator should fit nice and tight.
2. Add a dab of epoxy glue along one edge of the Negative Ion Generator and Grass Applicator Bottom.
3. Add a bead of hot glue around the Negative Ion Generator -EHT output wire and the Grass Applicator Bottom to block the hole.
4. Fit the push button switch to the Grass Applicator Middle.
5. Feed the Negative Ion Generator positive and negative wires through the Grass Applicator Middle hole.
6. Epoxy glue the Grass Applicator Middle and Grass Applicator Bottom together.
7. Cut to length, apply heat shrink and solder the Negative Ion Generator positive wire to the switch.
8. Cut to length, apply heat shrink and solder the 9-volt positive battery terminal to switch.
9. Cut to length, apply heat shrink and solder the Negative Ion Generator negative wire, 9-volt negative battery terminal and the grounding wire together.
10. Shrink all heat shrink if you haven’t already.
11. Feed the ground wire through the round hole on the bottom of the Grass Applicator Top then out the back.
12. Feed the 9Volt battery out through the rectangular hole on the bottom of the Grass Applicator Top.
13. Epoxy glue the Grass Applicator Top and Grass Applicator Bottom together.
14. Apply packing material to the Grass Applicator Cap to help hold in the battery.
15. Cut a 60mm hole into the centre of the Plastic container.
16. Remove the lid from the plastic container.
17. Screw the Grass Applicator into the plastic container.
18. Screw the Grass Applicator Nut onto the Grass Applicator.
19. Cut a hole in the plastic container lid and hot glue the wire mesh to the lid.
20. Connect the Negative Ion Generator -EHT output wire to the sieve wire mesh.
