1st mod in progress, TI LDO on the way

[Lonnie Lepp]

Started working on my first battery mod, A Puck.
Just need some silver solder, T reamer, Helping hands with mirror. I have everything else.

Texas Instruments is sending me a simple Variable Voltage Pulse Modulated Power Modulator.

I have not picked up a soldering iron since '74 in the Air Force Electronics School.

So far pretty exciting to build a working personal vaping unit.

Here is a diagram of how the next battery mod will be wired.
I will add to this as I go along.
a volt meter, some LCD lamps and a lanyard ring.

I would like to add an amp meter.

ETSY I be seeing you soon!

Its like riding a bicycle I'm sure it will all come flooding back to you
Just remeber which end gets hot and take it from there ;-)

Batteries - you planning on running dual 18350's?
I have a set of sample boards here to play with and a brace of 18350's

Keeping my eyes out for suitable boxes and cannot see anything that floats my boat
Look forward to seeing what you come up with

Regards
Rob

The Ti Chip is a
UCC283-ADJ
(ACTIVE) Single Output LDO, 3.0A, Adj.(1.22 to 8.5V), Reverse Current Protection, Thermal Shutdown

It is being sent to me as a free sample.

Congrats Lonnie on your 1st Mod

Robocog,

I am at present fascinated with NIMH AA 2000 mAh Batteries, Easy to buy and replace, safe construction.

4ea = 4.8 volts and 6ea = 7.2 volts

I found some interesting boxes at http://adafruit.com"]http://adafruit.com"]http://adafruit.com

5in x 2.8in x 0.76in, 8 x AA battery holder with 5.5mm/2.1mm Plug and On/Off Switch for 5.95

4.5in x 2.5in x 0.9in, 6 x AA battery holder with 5.5mm/2.1mm plug for 5.00

Thanks for your reply

What I really want is a box that measures about 1.25" x 1.25" x 5"

I could put 4 each AA batteries in the bottom.
On the top I could put circuits, lcd's, switches, meter face, and recess a Vivi Nova with back lighting.

But 1 step at a time.

Got to have a goal.

In this "dream Box I would like variable wattage (VW) instead of variable voltage. There is a wide variance in the resistance of the Vivi Nova atty heads. I think VW would make fiddling with settings a thing of the past.

would not surprise me if this VW stuff becomes the latest and greatest Personal Vapor Mods that folks will pay for. Time will tell.

Congrats Lonnie on your 1st Mod

Thank you Sir

hi! this AA configuration is enough to handle the sudden load, as the High Drain Battery?

Puckecig.com says the NIMH work fine and last a long time with a 3 ohm atty in the "puck" mod that I am building Now.

The second mod with the TI Board, I will start out with the NIMH's and see how they perform.
I can always rework the battery box for Li-on 14500's, probaly get 2 if not three of those in there. If I use a 4 AA box from Radio Shack.

I am learning a lot by being asked these questions and reading ya'll's comments

Thanks
Lonnie

PS Today I was alble to get some solder at Wally World.

 

[Lonnie Lepp]

Well progress is being made.

Soldered a few connections

Figured out that the LCD lamp is a one way street as to polarity. )

Resistor on the plus side and negative lead on the other.


Need a T handle reamer, Saturday's trip into town. ( we live in the country)

I also found that there really is no substitute for "helping Hands rig", I got by with some vice grips and ugly solder joints.

All in all a good first start.

I realize now that I probably should have ordered some pre-wired 510 connectors and used an AA box for the control unit side of the Puck. There does not seem to be enough room to get one of the new stardusts in an AAA box.

A very good day

Lonnie

More progress. Got a new multimeter and I ran tests on a 4.8 volt NIMH battery pack measured volts and amps using two meters and a load test with a 2.7 ohm 10 watt ceramic resistor. Stopped testing at 30 minutes. I did not know how low I could take the batteries without damaging them. started out with freshly charged set of batteries.

No load voltage of 5.67 @ zero minutes
Minute 1 under load, voltage was 4.35, amps at 1.24 for wattage of 5.3940
Minute 17 under load voltage was 4.00, amps at 1.15 for wattage of 4.6000
Minute 30 under load voltage was 3.77, amps at 1.08 for wattage of 4.0716
No load voltage of 4.74 @ 31 minutes
30 minutes times 60 seconds equals 1800 seconds.
1800 seconds divided by 3 seconds equals 600 each 3 second vapes
The batteries seem to recover voltage after they rest.

I am looking forward to using my new mod, now tha I got all the tools I need to put it together.

GO ME
AND
GO Everyone who has commented as you have helped me a lot..

Now if I can figure out how to get that meter face out of the smallest multimeter and wire it uo to show amps and voltage.

No load voltage of 4.98 @ 50 minutes

These are 850 mAh AAA NIMH batteries

Did a stop watch test of a vape and averaged 3 seconds per vape

 

[Lonnie Lepp]

Ruined my switch and the LCD
My solder iron is crappy.
Getting a new one soon

Also need
1 4 AAA baterry box
Pre wirred 510 conector
drip adapter to stop leaks
MOSFET
2 micro switches
I super bright LCD
Epoxy paste

 

[Lonnie Lepp]

Well destroyed a switch and 2 led's, bad solder iron

New switch and led's and new $9.oo solder iron and my puck is built and pucking along

At last a use for those old Volt carts!

Learned a lot.

Thanks again for everyone's help

I will send a pic tommorrow

Nice thread, looking forward to the pictures. I really like the TI regulators. Heres a link to a great affordable place for electronic parts and soldering irons. They have a great variable temp unit for about 15.00. hard to beat that price.

Thanks MrGreen819 for your kind words

I added the URL for supplies

Once I get the pictures off my phone I will upload them

[Lonnie Lepp]

My first mod a Puck!
