It could be due to it loading in HD. Try going to this link instead and watching straight from the YouTube page 😊

This idea sounds great, and agood challenge, I managed to view part of video on my phone, but it wont play on my pc? am I doing something wrong.
Thanks Colin.
Fair winds and calm waters,

HI Stephen,

Great piece of work, very good.

By now you should have a mountain made of mud and twigs in your front room that resembles the landing site !!!.

Kind Regards,

Paul.

Thanks Stephen
I was hoping you had developed an electronic solution. I am intending to use LEDs as portholes on my RMS Olympic and Bill's RMS Titanic. Total is about 1000 per ship, fortunately at 1mA or less for each LED, so what I need is a constant current at about 2.4 volts per LED. I intend to use electronic switchers to give some life to the models whilst on display.
Details will follow in the build section. Keep sending the signals, you never know who's out there!

Well I have tested in the water but not with the water jets operating yet 😊 and yes certainly the light effects look better after dark.

For powering the LED's there's nothing too advanced. They all get a 24v signal due to the controller so each individual one needed a resistor to drop it to 3v. The ones underneath however I've put them in series to get it to 24v. That's the most ideal method if you can do that. I have in the past used voltage regulators but you're then of course adding a big resistance to the circuit and it can get quite hot especially when you start stringing more and more LED's to the circuit... I have a reputation for doing this 😀

But if you take each LED as 3v you have either series or parallel configuration:

Series: 3v/30mA 3v/30mA 3v/30mA + 3v/30mA = 12v/30mA
Parallel: 3v/30mA 3v/30mA 3v/30mA + 3v/30mA = 3v/120mA

If you have parallel and a 12v battery you then also need to drop the voltage from 12v to 3v which if done through resistors means you then have a lot of heat generated and you effectively have 12v/120mA being drawn.

Hope all this helps! 😀 with LED's I'd start with the battery you'll be using and then work out how many LED's you need that when in series get 3v each (or at least do not exceed 30mA each).

And no, no contact yet 😟 😀

Really different. When are you having the maiden voyage? I bet this looks fantastic after dark. The water jets together with the sound and lights really work well. I assume you have some sort of PIC controlling everything. I am interested in how you powered all the LEDs as I have a project in hand that uses many LEDs and will need a good power supply. Well done and great to see innovation and model building skills shown to such good effect. Have you had any contact yet?

Well It's nothing you've ever seen on a pond before! Something I've been working on for some time... Partly because I'm mad and partly because everyone likes water displays right? 😀

It plays various different tunes, still some tweaks required before I actually do put It on the water. It runs on 24v although the motors are on 12v. It has 16 water jets with blue and green lights built In on each one that are all Individually programmable. 8 red outer LED's and another 16 colour changing LED's on the under side of the lid. Also 3 strips of electroluminescent wires not shown operating In this video, two colours around the very edge of the lid and another underneath. 8 flash bulbs which are actually LED halogen equivalents. These are programmable In sets of 2 and two marine speakers for the sound.

Inside we have the programming unit shown on the left, the pump, two accumulator tanks and a pressure regulator. Also the speed controllers for the motors and a custom built control board and small control box. The radio control receiver also operates a servo hooked up to a volume control pot and the controller so I can operate everything from the side. There are 3 batteries In total but surprisingly It doesn't draw much power.

So why am I posting It here? Because It's my website!... and I'd like to peoples response to It really. It's a unique project that's kept me busy for the purpose of pure entertainment and an electronics challenge 😎

Post your comments below! Does this project take radio control boats a step too far Into the realms of technology advancements? 😛
