    LATEST SMOKER, E-CIG ELEMENT
    This is the latest crack at a more compact easily made smoke unit using off the shelf (pretty much) items. I bought a top filling vape tank which arrived today and made an electrical connection base for it to start with. The base is industrial linen (formica,- or you could use hardwood) which is drilled and tapped to 4mm, and also counter bored to almost the thread diam of the bottom of the tank. The counter bore was tapped to 7mm but only to get the tank thread started, as this thread is very fine (7x.25?) and I doubt if you could easily find a tap to suit. Also the tank only has to screw in a small amount to hold it in place for the center electrode to contact (adjustable brass screw), and to trap the neg/pos wire which must contact the body. I made the center contact from a 4mm brass screw which is screwed in from the bottom till it contacts the center electrode (which is insulated from the stainless tank body) Under the head of this screw is the wire for the + (or -) -- also screw has a small piece of silicone tube on the inside over the screw to further insulate it ( don't want LiPo

    !) and the other lead is under the body where it screws onto the base. I tried it on 2v an 2.5v and it works very well (air being fed in the top (where you normally suck from) and the vapor comes out the adjustable air slots (which are normally the intakes.) If you could make a collar around the intake area you could either direct the vapor into a collector, or reverse this (air through the collar) and have the vapor exiting the proper way through the mouthpiece (preferable). to make it simpler I am just going to enclose the whole thing, and have the air feed set up through the lid into the element and the exit (tube/tubes) through the top or side of the container. This particular tank must be kept upright to avoid leaks but is small enough to strap to a bulkhead or similar. Have ordered another air pump which hopefully will be better than the previous disappointments! Yay another month to wait!!!😴 Looks promising so far though! JB

    LiPo Battery Charging
    NOT from me (RNinMunich)! I just edited it to delete a previous comment of mine! LiPo Battery Charging - Use specific Lithium Polymer charger only! Non-compliance may cause a fire, which may result in personal injury and property damage. - Do not let the voltage on the cells drop more than 2.75v / Cell. it is recommended to unplug the battery after use which would stop any further discharge of the pack! - Never charge batteries unattended. Whenever charging Li-Poly batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur. - if at any time you witness a battery starting to balloon or swell up, discontinue charging process immediately, disconnect the battery and observe it in a safe place for approximately 15 minutes. This may cause the battery to leak, and the reaction with air may cause the chemicals to ignite, resulting in fire. Since delayed chemical reaction can occur, it is best to observe the battery as a safety precaution. Battery observation should occur in a safe area outside of any building or vehicle and away from any combustible material. - Use caution to avoid puncture of the cell. Puncture of cells may cause a fire. - Wire lead

    can cause fire! if you accidentally short the wires, the battery must be placed in a safe area for observation for approximately 15 minutes. Additionally, if a short occurs and contact is made with metal (such as rings on your hand), severe injuries may occur due to the conductibility of electric current. - in the event of a crash, you must remove battery for observation and place in a safe open area away from any combustible material for approximately 15 minutes. - if for any reason you need to cut the terminal wires, it will be necessary to cut each wire separately, ensuring the wires to not touch each other or a short may occur, potentially causing a fire. if you accidentally cause the battery to short, place it in a safe open space and observe the battery for approximately 15 minutes. A battery may swell or even possibly catch fire after a short time. - Never store or charge battery pack inside your car or building in extreme temperatures, since extreme temperature could ignite fire. Charging Process - Never charge batteries unattended; Charge in an isolated area, away from other flammable materials; Let battery cool down to ambient temperature before charging. - Do not charge batteries packs in series. Charge each battery pack individually. Failure to do so may result in incorrect battery recognition and charging functions. Overcharging may occur and fire may be the result. - When selecting the cell count or voltage for charging purposes, select the cell count and voltage as it appears on the battery label. As a safety precaution, please confirm the information printed on the battery is correct. - Selecting a cell count other than the one printed on the battery (always confirm label is correct), can cause fire. - You must check the pack voltage before charging. Do not attempt to charge any pack if open voltage per cell is less than 3.3v Example Do not charge a 2 cell pack if below 6.6v; 3 cell pack if below 9.9v. - You must select the charge rate current that does not to exceed 1C (one times he capacity of the battery). A higher setting may cause fire. The below chart is calculated at 1 x capacity of pack. Example: 1800mAh: charge below 1.8Amps; 2200mAh: charge below 2.2Amps; 3600mAh: charge below 3.6Amps First Discharge: Keep the run time to 6-minute sessions with 15-minute breaks. Storage & Transportation Store battery at room temperature between 40F and 80F for best results; do not expose battery pack to direct sunlight (heat) for extended periods.

    Model Boat crew....
    A model vehicle - car, boat or plane - looks a little odd if it seems to be operating with no driver. Aircraft have quite a selection of different scale 'head and shoulders' figures - road vehicles seem to be made to standard scales so that driver figures are readily available - but boats are often made to a wide variety of scales and then need scale figures which are not readily available, and can be very pricey when they are! I was asked recently about figures on the boats I make, which are continuations of the Keil Kraft EeZeBilt line. These were originally 'pocket-money' starter kits for young children, so they were very cheap, and the fittings were not bought, but made from available household items like paper-clips. I have continued that tradition, so making an EeZebilt remains cheap and encourages manual dexterity rather than a large wallet! Figures can be made cheaply by adding filler to a wire armature, but this does require a bit of carving skill. It is easier to start with a basic shape and alter it a bit, and the obvious place to start is with a model railway figure. Cheap Chinese copies of products like the Preiser range are available on Ebay for around 10p per figure - see the link below for example. These figures are available in many scales from 1:200 up to about 1:24. The first point to make is that choosing a suitable scale to build your boat to will make it a lot easier to populate it with figures! I typically look to make boats at 1:24 or 1:48, two common scales for railways. Now the only problem is that the typical figures for sale are not sailors or naval personnel. Instead they are usually civilians, railway staff or workmen. But that is easily solved by using a modelling knife. I have illustrated this below with a set of drawings for a 1:48 figure - see the PDF link below: 1 - a typical figure. Note the jacket and tie lines embossed on the body. I wanted to make an Indian Naval Officer, so my first step was to look up the colouring and shape of their uniform. I find that they wear white, with either a plain-front tunic or shirt and
    shorts
    . 2 - To make a plain-front, simply scrape away the clothes lines embossed on the figure's trunk. You may also need to cut any hanging parts of a jacket away, or fill a hole with some modelling putty. 3 - To adjust arms, slice them off and then re-attach with Plastic Weld. The plastic will melt and conform to the new shape. 3 - To make
    shorts
    , just trim the long trousers in a bit at the
    shorts
    hem, then carve the lower leg to show the bulge of a calf. 4 - An officers cap is easy to make. Stamp out two tiny paper disks using a sharpened brass tube, and cut one disk in half. Cut a slot across the figure's forehead, and superglue the half-disk in there to be the cap peak. The full disk goes on top of the figures head, and the excess glue is drawn by surface tension to make a brim. The glue will soak through the paper and make it hard. See the PDF below for details...
