    Small ducted fan for portable bag-filling?

    I was hoping to debut my findings in a much better way, but due to a lack of time and a different project that's on my desk right now, my porta-bag filler has taken a back seat. I've experimented a lot with force feeding air through the Arizer Air's intake ducts. I encased the air intake area...

    VapCap Induction Heater for Desktop and in Car Use

    Me too! TBH, been exhausted lately, and I can't even recall exactly what I did last time it died. However, I'll keep experimenting till I get something reliable! Taking a break from the oscillator for a bit (Too much flux fumes!) while I play with some other things, and get more parts in! Damn...

    Thanks. He has a kind of Fallot type DORV, meaning the wall dividing the two ventricles isn't complete, so blood flows between them. The aortic valve over-rides the partition and receives some of the blood that's meant to go to the lungs, sending it back to his body. This results in a varying...

    VapCap Induction Heater for Desktop and in Car Use

    A little overdue update... I've managed to get this thing mostly built! :) This is still very much a 'prototype' though, as I keep changing things as I go.. Anyway, I've had some ups and downs with this. The first time I hooked up the minimum induction circuit, everything worked great. Since...

    VapCap Induction Heater for Desktop and in Car Use

    Not really an aftermarket upgrade. TBH, this thing is still far from leaving my work-bench. I have no intentions of actually making them, rather that I'd be more than glad to contribute to development of a portside 2.0. Induction heating the VC is awesome and @Pipes is leading the way, so enjoy...

    VapCap Induction Heater for Desktop and in Car Use

    Haven't had much time to play..... but, I've been playing all the time I've had! :D 'little' update.. I enlarged the hole at the bottom of the glass cup/tube and keep a little distance between it and the IR temp sensor, and it WORKS! :) Sensor still warms up a little and needs permanent...

    VapCap Induction Heater for Desktop and in Car Use

    Tnx. I was over-due on a little project. I'm a hardware guy in a software company so I neeeeeeed to build stuff to keep myself sane.. Was playing with PWM over the weekend and it was working really well though I blew some P-chans. I've got some higher rated ones to play with still. Ultimately...

    VapCap Induction Heater for Desktop and in Car Use

    It oscillates! :) When with my current limited 5A supply which goes down to 9.5V (~47W), first click is just under 10s, second clicks in about 4. It's controlled by a MCU which can also read temperature via IR. PWM works well so I can reduce idle current to almost nothing, though PWM driving...

    Middle right reversed Vin . Wouldn't have seen it if I weren't looking, so spot on for the PipesVision optical inspection.:tup: P.S Pipes you a machine. Great stuff! :)

    Not sure how many, but I can say that I'm responsible for about 8 of them :D My first @VapCap order was just before BF, before the discount, for 2 omni-vaps for a friend and myself. I already knew that some of my other friends may be interested, so I asked Matt if there were details about an...

    Due to the great nature of most of you guys on here, I'm assuming there were no ill intentions meant by @MoistLumps. I know that not everyone sees the harm in IP violations, and often out of innocence rather than ignorance, greed or malice. He's obviously following this thread eagerly since he's...

    It stays set due to friction. As you rotate the mouthpiece, the threaded stem extends/retracts within the body. The friction of pushing the stem in/out of the body (between the o-ring and the inner surface of the body) + rotational friction in the threading mechanism itself keep the Omni setting...

    Standard A.A stem measurements. LMK if you have any Q's or need more. Hope it helps. EDIT: Sorry missing a critical part. The lowest part of the narrower length of the stem is about 12.3mm (Just above H2). The OD right at the top is about 12.15mm. Obviously this is my specific stem, and as my...

    @ work though I have a digital calliper and an A.A so I'll try get some stem measurements for you when I'm at home later.. P.S your etsy links don't work since it's linking to pages intended for the account owner. I can get in through https://www.etsy.com/il-en/shop/WinegumsWoodcraft Here's...

    I won't comment on any personal styling preference, though I will say that if a specific combo is not on the site, send them an e-mail. They'll sort you out if possible. The omni is basically the same size as the OG you have. It is that same size as the standard Ti Woody S, and it will...

    VapCap Induction Heater for Desktop and in Car Use

    The royer osc. has serious munchies! It's not so simple to reduce it's consumption since it's a self-resonating circuit (Z=R for the tank, lowest impedance->highest current). If it were not self-resonating, you could de-tune it by driving at a different frequency. One way may be to PWM the whole...

    I haven't ordered that ZVS assembly yet. Fortunately, power supplies seem to have lots of the relevant parts.:brow: It also helps to have a bunch of parts lying around from amp building days. I think I just need to find suitable transistors and a PS. I have a bunch of 19v laptop supplies lying...

    VapCap Induction Heater for Desktop and in Car Use

    If the IR switch works it would probably have to be right under the cap and be mounted on top of the tactile switch. I'm not yet overly concerned with miss-use (like sticking a screwdriver in there) or accidents (how'd that screw get there?). More interested in tweaking it for intended use...

    @Pipes What gauge did you settle on for the work coil in the end? I've ordered 14awg enamelled copper already. Wondering if I should get a few others too. I still have to order the induction circuit since I doubt I'll get around to building one before I'd get it anyway. I've played with that IR...

    I haven't cleaned a cap yet. Regarding tip: Here's some shots of my heat-anodized tip after DIYing the grooves into the newer style. I removed the o-rings and used a vice-grip to gently clamp the bottom and hold it upright. Used my triple-flame torch but had to do it in sections so the torch...
