    New micro and cotton wick in the kfc is tasting a little w wonky.. Might have to do a better job of cleaning the cotton maybe.. hmm...
    The same thing happened to me Leo the first time I tried cotton in it , had to boil it a couple of times with fresh water each time to eliminate that taste .

    been reading about chipsets n all along with the "rattlesnake" effect and read about 33.3Hz PWM soooo I warmed up the O-Scope and did my calibration tests to make sure I was on par... Cal test passed... attached the leads to the case and center pin of the Vamo3 and hit the button... Flat line feed @4.7VDC ... odd, increased the Hz setting to a finer read and retested... still flat line, went thru all settings and flat line everytime. No pulse anywhere my O-scope goes to 20MHz. Either the PWM is way above 20MHz or Vamos chip is producing a very fine DC pulse ( 4.700 - 4.710 volt swing) ((about the thickness of the trace)) which would be considered straight DC current.
    Will test the SVD when it arrives too....

    I'd be skeptical of applying "fine" to the VAMO. It's Chinese made stuff. You get what you pay for though. :)

    My first coils that work. Not great I think but working. I had to mod the nimbus clone. No holes in the post and wrapping the wires around the screws sucks. So cut a flat spot on the sides of the post with a dremel then drill. Posts now have holes in them. Was going to take a pic with the coils working but my 18350 got low. Both in the charger now. Time to pick up more batts. May be 490 or 500s. Coil is 30gabout 3mil dia. 5/6 wrap. Vamo says .9ohm and wick is 2 bits of ekowool. I'm not a fan of cotton and silca was hard to get to stay in place. I don't have any cotton anyway. I'm glad this nimbus clone was cheap cause if building dual coils is always this much of a pain I'm not sure I'll keep doing it. Now that I have the Magneto I can put a mirco in the small RBA dripper I have. Maybe I can get it to work right:)

    I just finished up doing my own sub-ohm rebuild on my blue Reo. Replaced the spring with a car fuse and spade terminal, then ditched the OEM firing pin. That was replaced with a brass strap with a rolled tip for use with flat top batteries. Voltage drop has diminished significantly!

    Vaping with the REO has gone to the next level!

    Those look like vertical coils resting in the wick, no? Pix is kinda small.

    You are correct. When I tightened the screws they just turned that way. So I figured I'd leave them. I've read of other people doing this with mircos. I think on the next coils I'll make the dia smaller and see if I can split the ekowool and tuck the coil inside.

    Well Bronze Pro Vari Mini looks like it will arrive tomorrow:banana: Haven't received any shipping on the Loki rings...wonder if they might be closed until Monday. I've lived without the ring to date...just excited to have them look a little nicer when they arrive. So it's time to begin the new year with exercise. I have a tread mill I haven't used yet...going to go home from work and get out the manual..figure out a good routine to start with and take a little walk tonight. You know my dad always told me to quit worrying about the things I can't change or do anything about...and take care of those I can. Well I've gained a lot of weight in 2013...and it needs to go away. That I can control:D
