    Re: NON SMOKING EXHAUST WITH AIR INJECTION
    Hi JB, I have caught up now and by reading through the posts to see your journey. I have been on a similar journey - I thought I would share some of my learnings. The electronics in the vape devices may well drive a display, buttons +/- and a display interface etc but the basic electronics for the power to the coil are very simple. The power is "pulsed" to the coil using Pulse Width Modulation - basically in each cycle how much time the power is ON or OFF - very similiar to a domestic dimmer switch. By varying the pulse on/off period (Duty Cycle) I can adjust the power being supplied to the coil The coils do not have a voltage limit (I run my standard coils from a 12v SLA) - they do have power (watts) limit where watts =volts x amps. I am not sure on the spec of you voltage regulator - it may be constant current - so when you drop the voltage to 2.x volts your are essentially dropping the overall watts in the circuit. The resistance of most coils is single or sub ohm so are almost a short circuit - no surprise your voltage regulator gets very hot/spits it's fury I create my pulsed power to the coil using a MOSFET I also have a temperature sensor in place to auto shut things down if needed and will be a able to remotely monitor each of the 9

    Re: SEAPLANE TENDER, CHANGE OF ESCs
    Haven't found a programmer yet Peter but that's not to say there isn't one, although they work perfectly for what they are designed for. I bought some small 30A brushless ESCs a while back and when I asked the seller if there was a card for them he told me they didn't make one . With a bit of detective work I found a card under a different brand name which works fine. Pic is of OCDAY branded ESC and unknown card which works. How I found it was through an ad on Banggood, which showed the same ESC in a different colour and brand but with a card, so I found the same card elsewhere by itself and took a gamble and bought one, and it worked! Fans aren't too much of a problem as I use quite large main batteries (and they only draw about .02A) so the 2200MAh batteries don't even notice them (probably don't even need the fans, just something I put on 'cos I could'). New ESCs are 60A so they are not going to worry about a 2.5-3A motor draw max. Did think about water cooling but the extra pipe work wouldn't fit without a lot of reworking space, and it's a plumbers' nightmare already. I'll probably use the cheapos in the Maiami which I was thinking of converting to twins and giving the balsa hull a bit of fairing and maybe glassing. Really have to get rid of some planes to make room for any new projects, and finish re-doing the Graupner Optimist, and jazzing up the Fairacre launch a bit. Enough there to keep me busy for next winter. Will just be working on the

    LATEST SMOKER, E-CIG ELEMENT
    That one turned out quite well Martin. I was on the lookout for some sort of can to put the tank in and was prowling round our local Bunnings home depot/hardware store and was in the plumbing section when I suddenly had an epiphany. Remembered I had 40mm waste pipe at home so I bought 2 end caps and a bit of sanding drilling and fitting later, voila' version X. not that small but plenty small enough to go in most boats and very easy to make. There is a turn of loose wire inside so I can lift the tank up to fill it. Strange that it would not work as planned with a bottom air feed, and had to work in reverse. Not to worry, it makes houseloads of smoke, is self contained and easy to fill, (end caps are just a push fit and the top holds the tank in place by the mouth piece) which is pretty much what I was after. I know we can use the vape coils now and I'm sure I can make a small version with just a coil (same idea as the alloy one, - just need to make or find a smaller can) not too worried at the moment as I think I have enough
    smoke devices
    for now. Be interesting now Myself and Graham have kicked it off, to see what the rest of the crew come up with (I think there are a few under way at the moment). I'm sure no one is going to pay silly prices for the commercial smokers now! (which are pretty much what we have done but in a colorful tin) when you can do it yourself. Seen a few vids on You Tube of people making their own by winding coils on f/glass rope (stove door seals). They work ok but more effort to make. Ready made coils are so cheap (wound coils and replacement screw ins) that it's not worth mucking around. You can buy boxes of various wound coils very cheaply if you make something to use those in. Endless fun. Thank-you E-Cigs!๐Ÿ˜Š JB
