One question? What do you mean by "Resistors… Create Current"?
If you're going totally DIY on this, I'd recommend a single cell or cells in parallel - definitely not series cells.Ok, just about fed up with this project, even though I haven't received anything yet.. So I went and bought this on Amazon Prime. It will be here Thursday. This will allow me to use less 26650 Batteries to power my circuit, and if I read the specs properly, I'll be able to use only 1x MNKE or Efest 26650 (3,500mAh) Battery with this circuit, rated at 4.2vdc (3.7vdc Nominal). That means I can use 4 of these 26650 Batteries in Parallel and have my 7,000 or 14,000mAh Battery pack up in running,.
Here is the type that I (and some others here) have got. I like it far more than the type you pictured, and if you watch for sales it is not much more expensive. For one thing, replacement tips are more available and not expensive.Went and bought myself a 30 watt Soldering Iron. $10 @ RadioShack.
Are you familiar with Harbor freight? I got my DMM and helping hands there for less than $5. The DMM was free and I think the helping hands were $2.99 or something like that.My UNI-T UT61D True RMS DMM will be here tomorrow, along with my helping hands.
Its TRIAC controlled, not temperature controlled. This has several disadvantages.Here is the type that I (and some others here) have got.

Most tips are copper - the best ones are iron plated.
You need to plug the red probe from multimeter in 10A port of multimeter to measure current.
From manual:
To measure current, do the following:
1. Insert the red test lead into the mA or A input terminal and the black test lead
into the COM terminal.
2. Set the rotary switch to A, mA, or A.
3. The Meter defaults to DC current measurement mode. To toggle between DC
and AC current measurement function, press BLUE button.
4. Connect the test lead in serial to the return circuit to be tested. The measured
value shows on the display.
BLACK IN COM
RED IN 10A
With batteries you could omit that capacitor or so I was thinking...batteries after a while can develope weird crystal structures so you get oscillations too. You should have a 1uF to 10uF capacitor close to the regulator, on both sides.
Thanks, I've posted the results. Much better, thanks for the help.You need to plug the red probe from multimeter in 10A port of multimeter to measure current.

Thanks, I'll keep that in mind when I make it permanent.With batteries you could omit that capacitor or so I was thinking...batteries after a while can develope weird crystal structures so you get oscillations too. You should have a 1uF to 10uF capacitor close to the regulator, on both sides.
