    You'll be surprised what they steal here ! Customer had a full sheet of 25mm SS stand outside his workshop. He told me what it weighed, and it was heavy, you have to use a crane to move it. They stole it, and no one knows how they got it out of the locked area. They even steal the street name boards off the street corners. The man hole covers are now made from cement as the metal ones disappear.

    They probably won't steal the big part so easy, but the rest of it would disappear very quickly.

    Finally got the jig's cone on.

    The boat's LED lights completed.

    Can't believe how many people ask me how is it going to work, and even when I told them they still don't know.

    It's a rocket. I'm going to find my own planet to live on. Right after the boat is finished.

    I have some earth moving to do and a slab of concrete to cast to work on.
    All very exciting ;)

    Hi fanie,

    It looks great so far. Are those star leds in the lights?

    Yes, they are star LED's. Each light has three starled LED's at 1W each, so each light is a max of three watts. Doesn't sound like much, but in a space like a hull that's quite a bit of light. I also chose the warm white LED's, closest to the light the sun makes. Those bleak white LED's hurt my eyes, these don't. You can also dim them, save power and won't make you night blind.

    You seem to be quite the expert in electronics, so dimming LEDs and making barometers might be confronted as a childs play by you, but leave most of us with our mouths open, jaws hitting the floor. Your stuff looks great.

    Will those clear plastic light cases withstand the heat of the starleds? I hear they can gain some heat at full glow.

    The LED's generate almost no heat. Only the power device on the PCB develops a bit of heat at max Vin ie 15V and at max on, but there is no heat that can even remotely heat the lens up. I have left some on at full current overnight and you cannot feel heat on the lens.

    What is quite nice is that for the current drawed, they are almost double as efficient as other lamps. They don't make as much and as wide light as would a compact fluorescent, but one seldom needs such bright light. A few of these lights makes quite a bit of light, and at low current, so ideal for the application.

    People are a bit lazy, and it's sometimes hard to self discipline one self to learn something out of your field of experience. I made it a habbit to research things, so quite a bit of my time on the internet is reasearching stuff, not only electronics.

    Electronics is an ever evolutioning field, if you aren't involved you get left behind very quickly. Most of what I know I learned myself. Electronics and electrical things are not really complicated, most people out there just hasn't spent the time to make piece with it...

    As for the instruments, I have the following planned,
    The barometer you saw,
    With it should go a RH (Relative Humidity) meter
    Wind speed and wind direction - and this is kinda like a mini weather station.

    A digital clock with alarms for various purposes, night watch, get fish out of oven...
    I'm also working on a lunar clock to indicate the tides,
    a digital compass,
    GPS for indicating location, speed, time etc.
    Temperture indicator for inside the boat and one for outside.
    Some Volt and Amp meters and there will probably be more instruments.

    I also make 2 of each, so there's a backup. Waiting for the new boards to arive...

    There are LOTS of free electronic courses online. Now is a good time to start :D

    Hi Hoyte, we use electronic components now :D

    It's easier, since the calibration values are given by the supplier, you can just adapt them to display. I already have the sensors, just waiting for the PCB's, hopefully by the morrow and I can start on them.

    Thanks any way !

    Fanie, it looks like a giant Russian experimental torpedo with a nuclear warhead on the tip. F***** terrifying. I hope you are building a boat
