Help with Vamo small buttons and pcb fixing

[vanzza]

I'm have a Vamo v6 pcb chip ordered by mistake laying around and decided to build myself a mod. Just bought this case USB Power Bank 3X 18650 Battery Charger Box w LED Light for Cell Phone iPod MP3 | eBay and
have a momentary 12mm button from a coffe machine that will work nicely but need some tips on a couple of issues:

I don't feel comfortable to solder on the small button leads, any tips on what to use to make them work? Somebody mentioned that rivet heads would be a good thing to work with as an extension... But how?

Also, how can I fix the pcb to the case safely? Make some hot glue mess to give some height an then fix it there with more hot glue(is it safe)? It has no mounting points, after all it's designed to slide into a tube!

Any tips will be welcome. Or maybe I'll end up just attaching the 12mm button, throw the pcb inside the case and deal with opening the cover everytime I need some other buttons clicked.

Got all the gear and the project has started.
Doesn't anybody have some advice on the issues above?

Rivet heads are suggested as remote buttons. You drill a hole the same diameter as the head and pop it through to push the button on the board.

Obviously you will have to grind them to length. If they don't have a lip to keep them from dropping through the enclosure, you will have to stick em to the tactile on the board with a strong adhesive.


Sooo......


Modmaker.co.uk stock these,

Vamo Buttons

5mm Diameter Metal Pins x 10 (need grinding to correct length)

I'd suggest using these, as they have the necessary flange to keep them in place. Drill hole, and pop em in.


Alternatively, with a fine tip on your iron, maybe just give it a go with soldering tactile buttons? The chip is pretty cheap to replace if it goes horribly wrong.


For fixing the board, you could either:

Bodge up a mount with some perspex/wood/whatever you can find.

Use sugru, this stuff is great. Moldable for 30mins or so, and sets to a hard rubber compound.

If you really have to...use hotglue


Hope that's of some help?

Thank you mate.
I have seen those vamo buttons and they would be great but the shipping is 3x the price.
I have a buddy that just got a 3D printer I'll try to fix something with him.
My great problem now is soldering! Since my last soldering endeavours 18 years ago it seems I lost all my skills. Soldering is defined not the same as riding a bicycle.

Well... the deed is done.
Didn't went quite as expected but good enough for a first time.
I went for the easier to do / harder to operate approach - only the fire button on the outside, and if necessary open the case to fiddle with option. the problem with this is that the artist broke all small case supports (see the electrical tape holding it) and of course the big cover had one support half broken also, so I'm still figuring out how to fix it because lt will brake sooner or later and the cover will come loose.

Any ideas on how to fix the case cover will be welcome!
