Dynamite Flash

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Dynamite Flash

Postby Glen A » Tue May 07, 2013 8:17 am

I've had this joke sign on my layout for a couple of years:

Image

Now I was looking for some public interaction to add. Something they could control that wouldn't affect the trains running.

While out shopping I found a small key-ring charm that was a look a like miniature camera. It had a button on top that made the flash go off.
It used to look a lot better than this (it had a lens on the front), but I forgot to get a photo before I hacked it up :wink:
Image


Anyway I broke into it and found 3 small 1.5v batteries inside. There is no way they would last continuous use for two days, so I hooked some wires onto the connections in the battery area, so I can hook up to an old 5v cell phone charger. I also pulled apart the push button and wired that out so I can trigger externally.

Image

I can have a plunger out front, a push button behind the layout, or triggered by train via reed switch if required.

So then I cut a new tunnel into the mine:

And eventually you will see the flash coming from out the back while looking though here:

To be continued.....

Nice! It's amazing how you keep coming up with new ideas for this layout. You might need to build a couple of new modules to fit them all in!

Great idea.....just wish I could find an excuse to do it on my estate railway, but there's not a lot of call for dynamiting the Shropshire countryside in the 1970s!

G'day Glen

JUST LOVE IT :D :D :D

Just the sort of thing that I like on layouts.

Pity you didn't think of it a bit earlier .... just recently tossed a key-ring thingie that had a digitized explosion sound.
Would have fitted in with it perfectly !

Interesting to see what you come up with for an operating button out front.

Cheers

Glen,

Brilliant idea..........now what about a loud bang and some blast as well !!

I admire how you create additional interest into your modelling and adapt items for such use :lol:
Kind regards
Mark

Hi Glen,
Try this one from Jaycar
http://www.jaycar.com.au/productView.asp?ID=SP0786&form=CAT2&SUBCATID=978#1

I have 2 to wire in as "crash stop" switches for the Incline

:shock: :idea: Let the kids work out how to reset it - :twisted: so you should get some time between KABOOMS :!: :!: :!:

Thanks for the ideas of the buttons. But although they are big, they are not dramatic enough for me. :lol:
I want a big T handle plunger (like the top of a bike pump) just like you see in the old movies. With two bug wires running under the layout.

Adrian: yes pity you had thrown that out. I would like to add sound. but haven't found anything suitable yet. When I find something at the right price, it will get done..

Glen,

on the Wayback machine Archive I found an early book on explosives use in mines, and it has some great illustrations of the equipment used (including the plunger handles).

A page in the book (for a chapter on what NOT to do with explosives) has a great image of a man cracking open TNT boxes with a pick! :roll:

I'll chase it up and send the link,

G'day Glen
Glad to hear that you plan to use a 'T' handle for your switch.
Should look good.
But a word of warning .... make it nice and strong :!: :!:
Maybe even stronger than the real thing.
Most kids respect somebody else's 'playthings' but some don't.
Don't ask how I know.

Just a thought ......
Maybe a button out the front that operates a little man who pushes the plunger which sets off the explosion ?
That way you can use a nice solid button easily obtained although making the little man might be a little more difficult !

Cheers

Glen,

this catalogue from the Wayback Machine archives is downloadable.

http://archive.org/details/blastingsupplies00eidurich

It contains information and illustrations of blasting machines.

A bit like Gomez Addams! :D

Glen,

The attached link leads to a very interesting book. Page 42 shows the "Reckless way to open powder kegs". Definitely not advisable! The image might make a fun T-shirt logo!

The quarryman and contractor's guide; or, How to remove rock at least cost (1891)

http://archive.org/details/quarrymancontrac00kirkrich

Actually this book has a lot of early useful mining information,

cheers

I find it quite funny that with all the dire warnings about striking a spark with the pick that there is no mention of the danger of smoking your pipe!

Dear Glenn,

If you want a decent "kaboom", start with one of these

http://www.pricom.com/Trains/DreamPlayerLITE.shtml
(about as cheap as a ITTC ISD sound module, and a darn sight better in audio spec. User-loadable, and Fully purpose intergrated trigger IN and Control OUTputs too)

Source an appropriate sound file to start with from here
http://www.freesound.org/

Tweak and create a suitable end-result sound file using this
http://audacity.sourceforge.net/
(it's FREE!)

and fire the resulting signal thru one of these
http://www.mackie.com/products/srm1801/

OK, that'll scare the kids, maybe back it off and use one of these instead.

Whoops, still overkill, better try this...
