WOW that would be smoking hot :evil:
A question for the pros...

I'd like to build a unit for use in my truck, would this 7805 regulator be what I'd need to reduce 12vdc to 5vdc?

And would there be any fire danger, or possible electrical system consequences?

Thanks, I've got the mod bug bad...

Best Regards

Thanks,

I have a set of lighter jacks on order from Dealxtreeme, however, when I go to check my order status they never heard of me?

Well, I suppose I'll just wait, placed that order and paid through pay pal aug 30, but I also go on a road trip vacation next week.

Just panicy I guess...

This mod thing is kind of addicting..

Made a Nico Stick and a USB unit already, thought it would be cool to just make a mod for the car and leave it there...

I do not have another spare USB cable, maybe I'll just buy one of those? and bust out a dedicated car unit?

Thanks for your help
Best Regards

This is my newest unit, running a 510 atomizer with a Texas Instruments 5v regulator. It won't get hot enough to damage the box, but the batteries do get slightly warm with frequent use from being in the enclosed space w/ the regulator so I try not to chong on it nonstop. The regulators are so nice and small, you can fit them in almost anywhere.

Major big thanks to Shreck for the links and advice with the regulator on this one.

What size box is that?

I cannot find a box that CR123's will fit in except for a 4x holder that I got from battery junction. It's clear and I spray painted it, but it's ugly. (And I'm a whinny Princess and hubby is tired of looking for a nice box:rolleyes:) I want as small as possible. I got a 2x one, but there's no room for the connector and limiter and stuff.

He made me a 5v UPAC but I don't like it. I prefer the taste with a cart <shrug>, just strange, I guess.
Thanks ~ P

You can get a 5v mod in a 2xAA box with two 14500s if you don't mind working in really tight spaces:

Just throwing that out there.

What atty connector is that? I can see how everything else is wired but cant tell what you did to wire the atty.

It's the connector from an M-series USB charger. They fit the 510s perfectly, and they are a rounded square in profile. I drilled a hole almost large enough for it, then heated it with a soldering iron and melted it into place before glueing. That way, there's some inherent reinforcement when twisting it to insert or remove the atomizer. I really prefer using them to just pulling the connector off a battery, and you can get the M-series chargers for about $4.

Okay, could you post a link to the charger you used? Also, one more question, I know how the connector is supposed to be wired but can't see the wires, especially the ground. Do you have the ground running under the voltage regulator and soldered to the negative plate of the battery holder?

Sorry for all the questions but I would like to make sure I have everything straight before I venture into this one. I've made 5v mods with a voltage regulator and also a booster and can't seem to get this one figured out completely.

No problem, Opus. I'm using my phone to view the forums while I'm at work, but I'll post a link to the charger I used when I get home. The wiring is hard to make out -- I don't have a good camera. Basically, the black wires are below the red ones, and there's a shadow, makng them pretty much invisible. When I post the link tonight, I'll try and explain the wiring better.

I haven't seen anyone try a 5 V voltage regulator yet

SparkFun Electronics - Voltage Regulator - 5V


I've been making them for a while- I've got blue ones, black ones, red ones and pink ones. I am now adding LED lights to them. Glow in the dark green ones and and even video instruction on how to make one.

Click link under my sig. for video instructions. Video (that works) is on last page of that thread.

I usually go with this one, because there's less garbage to throw away after I take it apart. Sometimes, I'll use this one instead, because you can get a USB connector if you need it, or just use the wire from the cable. The both also have LEDs that can be salvaged.


Also, one more question, I know how the connector is supposed to be wired but can't see the wires, especially the ground. Do you have the ground running under the voltage regulator and soldered to the negative plate of the battery holder?

It's connected just like any other voltage regulator setup. The center pin from the voltage regulator is soldered directly to the negative battery plate -- it's close enough that you can bend it so that it's almost touching, and then just blob the solder on to connect them.

So basically:

Red wire: From positive battery connection, to the switch (or just solder directly, like the ground of the voltage regulator to the negative plate), then from the switch to the Vr In of the voltage regulator, then from the Vr Out of the voltage regulator to the center pin of the atomizer connection.

Black wire: From the center (ground) pin of the voltage regulator to the negative battery plate as discussed above.

Black wire: From the outer ring of the atomizer connection to the negative battery plate.

Does that clear it up? Really, it's all pretty standard, just hard to see in the photo, so if you've done these before, your instincts are probably correct.

Thanks, mnealtx! I'm still very new at this, and that one was the first time I ventured away from the tutorials and just created my own from scratch, so I'm pretty proud of it. My imagination exceeds my electrical know-how by quite a bit, so I've got about a dozen mods I haven't figured out how to make yet. So when I actually make something work, positive feedback is definitely appreciated.

The feedback is definitely deserved - it's a tight, clean build (I wish mine looked half so good).

I'm with you on this. I made one of these based on his design with an RCA connector. His is much better looking than mine. It is a real chore trying to solder everything without breaking the solder on something else. It works and the lid closes completely so you don't see my crappy soldering or the hot glue inside.

That's why I went with a 3AA box for my builds - more working room for components and wiring. How much working room did you have after putting in the RCA connector?

Very little! I learned after installing that I really should have trimmed off the positive center post and ran a small wire instead of soldering the Vout of the resistor straight to the positive of the RCA. I bent it 90 degrees so they would touch but the solder joint is not very strong.

I agree. Robert does has some nice 5V's..
