Resistance measurements - facts and myths

Again and again we see the questions such like "how many wraps shall I do to get a 1 ohm?". Often the answer is "buy a multimeter" and then sometimes somebody answer "there is NO WAY to measure such low coil resistance by use of regular, cheap multimeter!". Is it true? Let's see... I wrapped some microcoil on the MutationX atomizer and will measure its resistance by use of several multimeters. Starting from expensive, calibrated meter by Keithley....

DANI Extreme v2 by DICODES

DANI Extreme v2 was released by Dicodes together with 2380 mod (actually 1-2 weeks earlier). And they are twins. 2380 is is a little bigger and more powerful but the rest of technical specification is the same. I described the 2380 firstly, but some features have been omitted (e.g. "heater protection" modes) so in this post I'd like to present the full, deep review of second version of DANI mod. Most of features (actually ALL) of Extreme v2 is...

What the PWM is?

Do you know the Vamo? Or other "budget" mods? For sure yes...If we look at the voltage shape of such mods we will see something like that: For comparison, let's look at the ProVari voltage shape: So, looking at the PV voltage shape everything is OK - the voltage is smooth, stable at 4V, and that's it. But what is going on with the Vamo? Why the voltage reaches 6V and oscillates to zero volt? This is how the PWM works. PWM means the Pulse-Width...

Snow Wolf 200W - May the FORCE be with Us

At this time we have the MONSTER - Snow WOLF 200W: 1. The FINISH. Hmmm ... the first thing comes to mind after looking at the Wolf is ... iPhone :-) The aluminum, the "mirror" on the walls, and generally its elegance is such Apple products: One will like it, others probably not, as usual - a matter of taste. I like it. After taking into hand feeling changes a bit because ergonomics is still very good, but the impression is dominated...
