New More Powerful DIY Static Grass Applicator Pt1 (165)

- The static grass applicator I showed how to build about a year ago had some limitations. For one thing it was not very powerful putting out only about 2,000-3,000 volts. Also the strainer basket was a bit small so didn't hold a lot of static grass and there was no way to put a top on it so you couldn't really shake it. Finally the mesh was pretty tight which made it hard for static grass longer than about 2 mm to get through. So I cam up with this design based on one like Luke Towan's with a bigger container with a larger screen mesh, and the ability to put out up to 20,000 volts! In part 1 I'll go over the design and components and show how to put the handle and container together. In part 2 we'll wire up the electrical components, power it up, and see if it works as planned. So let's get started!

Looking forward to the next part. Your channel is really helping me get my layout to work as one should.
Thanks Larry this looks a good bit of Kit, looking forward to the second part. Keep safe.
I can’t see trains every time!! That’s what I really enjoy!!
Thanks Larry. I built Luke's Applicator, and it works a treat. However, I like the way you have made a low profile version. Well done. I'll look forward to part two. I think I may convert mine!
I built one from Luke's video but I had no luck powering it with an old 12v phone charger. Thanks for sharing your version.
Hi Ron-it should work with a 12VDC power supply as long as it is still good. Those old chargers can fail. I like the freedom of using the 9VDC battery myself so skipped the wall wart approach but it should be a viable option using Luke’s wiring diagram. However I don’t like the idea of using the rocker type switch as it leaves the unit powered unless you find a switch that is spring loaded and returns to the off position by itself.
Thanks for this Larry just came at the right time made a fly swat one at Christmas, but need something with a bit more power but needed a bit more info on the generator. keep up the good work from Matt over the pond.
Be careful buying a generator on eBay as they come in many versions, some with multiple output wires and some with only one output wire. To keep it simple I found one with 2 wires in and 2 wires out.
Thanks Larry.
Super. I'll give it a try. Thanks.
Thanks for sharing!
Engineering 101 looking forward to part 2
Never realized there's not much too them
Just a little tip for anyone making one following this. That screen could be tacked in place in just a few seconds with CA glue and zipkicker. Then you can go ahead and put the epoxy around for a more durable hold. I'd also get at least two extra lids for progressively bigger screens. With one of these applicators one size fits all is not best. The different length static grasses will work better or worse with larger or smaller screen sizes. Basically the smaller holes for shorter grasses and bigger holes for longer grasses.
Hi Larry, came over from the "angry space soldier" part of the modeling hobby. I love this video and I'm going to post it at a couple of my usual haunts on the internet. We dont do as much big pieces as you so buying a static grassdevice isn't really a good choice but building one is a great option. We do a lot of bases for out models, 3inch to 1.5 inch typically, and this static generating tool could offer us a LOT of choices.
Thanks!
Jason, thanks for spreading the word-Larry
Just went on a hunt last night to build last years model, it's good didn't find what was needed. Starting a new hunt now for these items instead.
Subbed, you are such a nice guy
I have shocked myself enough times with my current static grass applicator, I am not sure I need something more powerful, LOL
MORE POWER.......zap.......twitch.....
Be awhile before I ready for grass "but-when..I am..I'm gonna be ready Larry thanks CYA Monday
Thank you for this! I built a flyswatter version, but I found that the epoxy I used didn't stick the mesh to the lid. I'll have to try JB weld.
Also make sure to sand the plastic in advance to give the glue something to stick to.
YES YES YES. I love it cause its cheap wooooooooooo. Thanks for the video.
Thanks Larry, enjoy your videos. They’re always interesting and informative. I’ve been thinking about this video and wondering if you’d considered using a step up power booster to raise the voltage to 12 volts. Would this increase the output voltage to the complete 20k?
I’m going to give a try when I build mine. I’m just waiting for the supplies to build it. Thanks again for your great videos!!!
I do have one of the little voltage booster circuit boards a d may give that a try. However you can’t get something for nothing and a boost i voltage will mean a corresponding drop in amperage, don’t know whether it is the voltage or amperage that matters most in this case but worth a test. I was looking back at the results with the 9VDC and the third configuration was so good I may not fiddle with things until I get my hands on some 12 mm grass to test with.
Nice vid.
If your wife gave you one of her containers, you darn better use it.
cya Monday
Larry what is your opinion on the Woodland Scenics Static King or the Static Grass Starter Kit. And what size Static Grass 12 MM 7 MM 4 MM or 2 MM is the best for over all Thanks Tom
Have never tried them or seen them used. I will say that I have used Woodland Scenics static grass and I found I like Noch better.
What is the part number for the ion generator , will make it easier to find on eBay
Give me time to finish the video and get a parts list added to the description.
Larry, Do you still notify interested folks on their emails to remind them of your latest videos? I used to get them and it was a very useful reminder. I have thoroughly enjoyed all of your videos that I have had a chance to watch. Being a novice, it would be helpful for more DCC wiring videos too.
Philip-TH-cam stopped sending out emails back in August 2020, believe me I and everyone I know liked getting them but they decided otherwise. However if you have you have the preferences in TH-cam and on your mobile devices set to receive popups and push messages they still do those. Also on your subscriptions list there will be little blue circles when a new video is posted. And on your TH-cam Home page there usually is a special listing section for new videos from channels you subscribe to.
@@TheDCCGuy Thanks.
Is your website down? When I try it gives me an error message
Yes, I announced some time ago that it would only remain up until it was time to renew the hosting agreement and that happened in January. It was just too expensive to justify and it took too much time and money to keep all the security updated. I got hacked a couple years ago and that alone cost me $1000 just to get it fixed.
The output is not linear with input... 20kv/12vdc is not equivalent to 15kv/9vdc... but unless you actually measure it, you won't really know. Regardless, you will have less output than max kv. I use those modules and they work very well in the flockinator I make.
I figured that might be the case although it should not be a significant drop, but since my voltmeter max’s out at 10K I have no way to check it. Have you seen a typical response curve for these devices?
)
about those china made transformers.. has anyone reported any case of arcing¿¿ im kind of concerned about it. I know low current most probably wont kill you but it still hurts, I learnt that the hard way with some CRT tvs.
Watch the whole series on these applicators. I show a further modification that puts the “hot” plate at the back of the container instead of on the screen so you can’t inadvertently touch it and get a shock.
@@TheDCCGuy thank you!
I’m not going to start messing around with getting a static grass applicator that a major manufacturer hadn’t made. I have a disability that makes this a slightly dangerous thing for me to do!!
