The ACDC

[TomCatt]

Here's another box mod

I'm calling this one the ACDC - maybe pimp this one up, what do ya think of a picture of Angus on the back? .

Incorporated BJ43's VVBox and VVpassthru in this mod. I had the DC power jacks from my Coffin VV PT and just needed a DPDT switch. BJ43

The box is a bit larger than I'd like; but I'm getting quite used to it

Parts:

100mmx60mmx25mm project box ($2.37)
This LM2596 buck module from eBay ($4.25)
eBay switch ($0.60)
2.1mm DC Power Jack ($0.80)
RadioShack DPDT micromini toggle switch ($3.99)
Atty connector ($0.99)
2 14500 900mAh batteries

Parts Pics (forgot to include the toggle switch)

You got room for a meter....

I may do that with the next one. I still have another one of the boxes.

Oh, yeah, forgot to mention this: Plumbing Epoxy Putty ROCKS! This stuff sticks to everything and sets up fast.

Smooth box. If that toggle isn't too permanently attached you could move it over some and cut a slit so just the tip sticks out and so it can be switched from the outside. I also like that it doubles as a master switch provided it isn't plugged in.

I was looking at RS slide DPDT switches; but anything rated over 0.3A was a bit large; so I went with this 'micromini' toggle. I thought about making a slit and having the toggle stick out, but had decided to keep the pot adjustment internal, so I kept the toggle internal as well. Plus that meant one less place for me to screw it up .

Yeah, the DPDT switch does serve as master switch also; this was BJ43's concept with his VVBox/VVPassthrough. Although the rocker switch BJ used is an ON/OFF/ON three position switch, so that is a true master switch.

How about this for the box?

Nice clean box, but I'm seeing a little unused real estate though...bet you could get a couple 18650's in there...just pushing your fire button, well done Tomcatt!

[TomCatt]

Thanks Q! I still have another one of these boxes and some 18650s and a couple of voltage displays coming and....
