Self build

[Lord Grim]

The bits arrived yesterday


And should fit in the box something like this (obviously the 510 and fire button will be recessed into the box, not floating):


There's a fair bit of farting about involved with this: The battery sled doesn't fit so the bit that goes across the top of the box will need cutting down (or off, as the juice tube needs to go past it too), the side walls need chasing out to accomodate the cable run, and the squonk hole needs cutting out.
I was thinking of putting that on the corner of the long edge nearest to the bottle. Seeing as it's not a huge box, that seems to be the best way to create a hole big enough to get my sausage thumb in without exposing half of the battery.

Any helpful comments or suggestions at this point are very welcome.....

First fix is well and truly underway

Most of this was done with a drill, a dremel and a powerfile, which after the Workmate was the greatest thing Black and Decker ever made.
There's plenty still to do, I still have to chase out the channels for the wiring, do the wiring, go mad on sanding, decide what to finish it with (I'm thinking Danish Oil but I'm open to suggestion) and find a way to fix everything permanently without resorting to hotglue, but for now, it's Friday night, there's Hobgoblin in the fridge and I am only human.

Looks brilliant so far @Lord Grim great work

Looks great. Are you going to add a mosfet and fuse? Just curious... [emoji106][emoji106][emoji106]

Nope, this one's pure mech (ish). It's a prototype, if it goes well then I'll teach myself how to make wooden boxes (or just make a router jig and buy a nice blank) and while I'm at it I'll brush up on basic electronics.
I'm thinking about the new DNA75 chip.

Yeah, I've been tempted with one of this Floris Delfino enclosures, literally just slot in a chip, wire it, the switch and 510 together, jobs a good 'un. I think he does dna75 squonk enclosures...

Your box looks great, I really like the cutout for squonking as you've done it. [emoji106]

Thanks, it seems to work quite well, although the bottle's a bit stiff and I won't actually know until I try to put ome juice through it.
I really don't want to use a bought enclosure if i do another, I want it to be all mine!
I really do like the idea of making a prototype box with a router in cheap lumber and then when I know it'll all fit together, investing in a really nice bit of hardwood, or even cutting and seasoning my own, although that'll be a good couple of years before I can build it.

Thanks, I had no idea how it'd look, but I'm quite pleased with it so far

Right thou bugger, you piqued my curiosity with your talk of mosfet and that. I've worked out my amperage based on my usual coil resistance and a nominal 3.7v and it looks like it's going to be slightly over double the switch rating (something that if I'm honest I didn't factor in).
So, I'm looking at a (hugely over compensated) 195a mosfet from modmaker.
Just got to work out how to wire the bugger, and more to the point, make it fit in the box.
Would I be right in saying that being n-channel means it has to go into the -ve path between the battery and switch, obviously also meaning that I need to put the switch on the -ve side?

Theres 3 pins G, D and S. G- to one pin on your switch D- to negative on 510 and S- to negative of battery also solder a 15k resistor across G and S.
