First 5v box mod

[FandZ]

Hi all, tomorrow I'm going to be working on my first 5v box mod. Everything I'm using I bought from Madvapes and radio shack. I'm a little uncertain about the wiring of the switch. I plan on running only a positive power line through it. It has 4 connections on it but I'm thinking I don't have to utilize all 4, only one side. Is that correct?

My wiring will be like this:

Negative atty to ground on 5v regulator

Ground on 5v regulator to negative on battery 1

Positive on battery one to negative on battery 2

Positive on batter 2 to side A (prong 1) on switch

Side A (prong 2) on switch to voltage in on 5v regulator

5v Voltage out to positive on atty.

Press button and experience vapeing bliss???

Does that sound right?

I'm attaching a picture of what I'm intending to machine out of wood tomorrow. The springs for the batteries and prongs on the 5v regulator are not shown.

The yellow box is the 5v regulator that I'm planning to solder onto the addy as a heat sink. I think the rest is self explanatory.

Hope this works out with no fires or exploding batteries

The only problem with your plan is that you'll toast your button. Tact switches are only designed for a few tens of milliamps of current. Your mod will be sending 2-4 amps of current through it. It will probably work for a little while, but not for long. What you want is a regulator with a control pin. That way, you're sending almost no current through the switch itself.

Thanks for the heads up. How about I flip the batteries around and just run the negative lines through the switch?

Current direction is irrelevant. You've got too much current for a tact switch no matter which way it's flowing. You either need a pushbutton that can take it, a regulator with a control pin, or a MOSFET to do the switching for you.

Thanks a million. I'll head over to radio shack in the morning and get another momentary button. May have to spend some time redesigning the case to make the button flush. I think all of the ones sold in the store will be on the bigger side.

Looks nice though. Wish I could help with the technical stuff, but I don't know alot about electricity and wiring and such.

What kind of wood?

 

[5cardstud]

If you got a switch with a higher volt/amp rating on it then you'll be ok.

Thanks man. For wood, whatever looks good at lowes. lol Probably poplar. It's cheap

 

[keveck]

Well, that's acceptable for now. But when everyone sees how nice they look, start using the good stuff! Then sell em!

BTW, I get 5% of the profits for the idea.

The switch you get can also be rated for AC voltage. As long as the volts/amp rating is more than required you'll be fine.

Thanks for helping me on the button guys.I stopped by radio shack and got a bigger button. 3a @125vac. I decided to do a long tower instead of a box mod. I'm attaching a picture of what I'm making. As we talk my cnc router is cutting out the first 8 parts. I only will need 7 but I thought I should make an extra just incase. I'm still working on the top 2 pieces and the bottom piece. I hope to get them done by tonight.

I think I'm going to call it my side shooter.

Don't change the switch, change the reg.
Get the 4 pin reg from madvapes.

When I order some 18350 batteries from them I will but for now I gots to get my 5v vape on this weekend. Can't wait for shipping.

Well that was a big fail. I have a cheap HSS chineese router bit I use for cutting plastics that I tried to use to rout the poplar. As you can see below I probably would have done better using dental floss. All the cuts have a lot of jagged edges and it caused the wood to chip up. There is also some burn marks on some other pieces. Ahh well will try again tomorrow with a Bosch bit and see how that works out.

Bummer. Those are some pretty intricate shapes to pull off by hand.

Anyway, I thought I might mention that the Radio Shack regulator is only rated for 1 amp. It's likely to fail under the load.

It was with my cnc machine. I think the cutting bit is just dull.

Round 2 is going much better, It's not as cool as my 1st two designs but it'll work. I'm back to a side by side setup and am about ready to glue the parts together and start soldering. For a first mod I think It'll be great.

 

[FandZ]

Got my button and fittings in. Now it's time to stat soldering.

 

[WhatAClumsyGirl]

Wow...unusual and very interesting !

Very nice

 

[FandZ]

I went about soldering backwards. I went bottom to top when I should have gone from top to bottom. I also only have some thick gauge wiring that is making matters worse. I'm going to have to cut out a new top and re-solder. I also ruined my first battery connector by over heating it and the center piece came out. Glad I ordered a spare.

Hopefully the third try will be the charm.
