Build your own static grass applicator

[@jamesdavis-dn6hq]

Really nice video! Clear, concise, informative, and encouraging. I’m really looking forward to tackling this project! Thanks!

[@Bluedruid13]

I like the idea of using tape to hold the button while reassembling it.

[@KillBoxScalemodelling]

Yeah, it was really fiddly to get that sorted ;) :D

[@I_Don_t_want_a_handle]

Excellent. A couple of quibbles ... I'd've turned the bottle around, stuck it through the plastic and had the sieve stuck to the closed end (with a big hole in it, of course.) That way, you can fill the bottle from the top without flexing the wire and the join to the sieve. That's a point of failure, I would have thought. You can make a hole quicker with a boring tool like a drilling spade or a hole saw. Heating your knife speeds things up too.

[@BooklessT]

Brilliant! As fallout, I now have drill press envy.....

[@lunhil12]

I like the idea of using a pill bottle and small screen to contain the fibers. I think I will modify my old one ( just an open basket screen) to match yours. Well done!

[@KillBoxScalemodelling]

Thanks, good luck with your modification :)

[@rex758]

Smart way to save , great tutorial. Thank you.

[@KillBoxScalemodelling]

Your're welcome :) Happy modelling!

[@theaussienurseflipper.8113]

Great video, do have keep pressing the button or just hold it in? Cheers Graham

[@eugeneg68]

Very good tutorial! I would stick the mesh to the lid with epoxy glue

[@KillBoxScalemodelling]

Thanks! :) Yes, that is an excellent idea, good call!

Lovely, relaxing music. Great tuturial. If i use larger batteries for more volts, will the results be even better?

[@KillBoxScalemodelling]

Thanks. The design is limited to ~2kV output voltage. Increasing the output voltage would require a total redesign. The easiest workaround is to buy a negative ion generator and use that instead.

[@mjtunstall1976]

if you paint the board tan or light brown colour saw raw sienna it will look good when putting grass there btw, have you thought of using the dremel tool to cut the bid instead of the stanley knife? looking good now this is what im looking for!

[@kerel995]

Seriously. All hobbying youtubers should be on your patreon, learning how to make calm, informative, relaxed videos with right camera shots. Man I loved those close ups. What camera do you use?

[@KillBoxScalemodelling]

Wow, thank you! I use my mobile phone, most of the content on this channel where shot with a Samsung Galaxy 4 I think.

[@kerel995]

@@KillBoxScalemodelling loooool haha. And all them with tens of thousands worth of equipment cant just make a good close up

[@iflyrcmike]

Thanks for this, just made one and it works perfectly.

[@KillBoxScalemodelling]

Nice work!

[@shaunthfc7451]

If you find the centre of the lid and use the correct size hole saw.. If it's to small you can file or trim to fit. Saves drilling 20 holes in the lid. 👍

[@KillBoxScalemodelling]

Yes, that would work, but unfortunately I didn't have a suitable hole saw, so I had to do it like this... :P

[@davideblen9899]

At last, one of these that clearly shows the wiring! Bravo! Going to my studio right now to build one. Thank you.

[@ThreenaddiesRexMegistus]

Great job! Nicely explained too. I will be making one of these for my UFO cow abduction lamp.

[@KillBoxScalemodelling]

Awesome! Good luck with your build :)

[@ajandrade1]

Great work and very well explained, thank you.

[@flybobbie1449]

I wonder if you rub a blow up balloon to create static, pass it over grass, would it stand on end. As if you do it with small ripped paper, it stands on end.

[@KillBoxScalemodelling]

I haven't tried it, but if you give it a shot, let me know how it went

[@cammacgregor9354]

Very nice-!!

[@sunchaserw1477]

how may I determine which wire should go to the metal sifter or the base if there is no +ve and -ve sign on the circuit board? I just want to know how to determine where the wires should go and sometimes there are 3 wires on the board. Thanks very much.

[@KillBoxScalemodelling]

If you look at 3:44 in the videoclip there are two wires that should go to the outer mesh and one wire that goes to the inner mesh. The two outer meshes is the -VE and the center is the +VE. If you feel comfortable with reading schematic diagrams and have an understanding of electronics, this video clip explains the circuit in great detail. kzbin.info/www/bejne/r3i1Y3pqpq2gbMk The big 2kV capacitor on the output is connected to diodes (which are part of the voltage multiplier circuit) - the side with the Catode connected to the 2kV cap is +VE and the side which has a Anode connected is -VE. The diodes are marked with printed ring on the Catode side the other side is Anode. Hope this help you. Remember that this is a high voltage circuit so be careful.

[@شامخكبرياء-ر3ظ]

Is the grass from iron filings or what?

[@KillBoxScalemodelling]

No it's plastic fibres, they are used a lot by model railroad builders (that's where I first saw it). Check out manufacturers like Noch, Woodland Sceneries and War World Scenics on the web

[@شامخكبرياء-ر3ظ]

@@KillBoxScalemodelling Thank you very much, but how are you affected by magnets when they are made of plastic?

[@KillBoxScalemodelling]

@@شامخكبرياء-ر3ظ It,s not using magnetism, it is an electrostatic field

[@harmassink881]

I made it today, but the grass is not really standing up. Somebody an solution for this? I used 6 mm grass.

greatvideothanks

[@KillBoxScalemodelling]

Thanks for watching :)

[@therebelfrogy9287]

The problem with these kind of videos is that people who watch dont have the tools

[@KillBoxScalemodelling]

Yes, it's true for some people, but there are also lots of people that have access to basic workshop tools.

[@Grauskegg]

Can you pls link where you bought the zapper thingy. I didnt understand your Swenglish :P

[@KillBoxScalemodelling]

My swenglish can be difficult to understand sometimes :D I said "pound shop", but basically any place that sells cheap household stuff from China have this product (or similar ones). I bought mine at JULA (in Sweden).

[@Grauskegg]

@@KillBoxScalemodelling Alright :P No link? It would be cool to get the same model you' ve used. I got a crappy one from my nephew.. but the wiring look different.

@@KillBoxScalemodelling Tack så mycket :P Jag är ny i minifig-målning / diorama -hobby.. och har köpt massa prylar och ville inte lägga ytterligare 400kr för en elpryl som fixar grästuvor. Sen de man kan köpa färdigt är ju stöpta i samma storlek, vilket jag tycker är trist. Nu kan jag fixa hur jag vill själv! Stort tack att du orkade med mina förfrågningar! :) Häls. Nybörjare.

[@KillBoxScalemodelling]

@@Grauskegg För all del, jag kunde först inte hitta den på JULAs hemsida, så jag trodde dom inte sålde dom längre.... Men så sökte jag på insektsracket och då fick jag napp :) Lycka till med dina byggen!

[@InobuZ]

Not enough voltage.....

[@KillBoxScalemodelling]

Yeah, that's the drawback with this design. A negative ion generator is the way to go if you want higher voltage, but the pricetag will increase of course ;)

[@InobuZ]

@@KillBoxScalemodelling Yeah, Debating on swapping out the Cap and uping the input voltage verses like you say the Neg Ion gen...$21 now.

[@camerondpack]

Silly question... Has anyone ever tried dusting the area with static grass and then raising it with static electricity generated from a balloon rubbed on your head?

[@KillBoxScalemodelling]

Never tried that one 😀 - I think the static grass flock will get stuck in the glue when you apply it, but maybe it will work anyway... 🤔

[@pat2633]

please turn off the music so an old fart like me can hear what you are saying lol

[@KillBoxScalemodelling]

I'm an old fart too, so I need to keep the music volume up so I can hear it :) No, seriously, you are not the only one commenting this, so my later videos have a much lower volume for the background music.
