I really cannot believe that you posted this. I think this is the 3rd time you have started exactly the same thread in just over 4 years. Nothing has changed. It's going to end up with the same shit fight as always
1. Its balast so its not a dinghy - you will argue that you can have ballast on a dinghy because humans are ballast = shitfight.
2. Balast cannot be practically moved fast enough - you will tell us all about the motors which can move the stuff fast enough. Most (all?) won't agree. = shitfight
3. It's potentially dangerous. You will argue it isn't = shitfight
4. There is no demand for something like this. You will argue there is = shitfight
I honestly cannot remember all the other things that go on, but you get the picture. Or are you saying there si something new to add to the discussion? If so, it certainly isn't in your first post.
I seriously don't get you. There are discussion going on all over these forums that you have and can make valuable contributions to, yet you choose, once again, to drag up old stuff.
Kickstarter http://www.kickstarter.com/hello?ref=nav If you can't get funding via Kickstarter, you don't have a market
And if you really believe in this, you could self-fund it. a fast PLC costs about $300 http://www.plcdev.com/cheap_plcs
your sensors and actuators for the movable ballast about $500 since that sort of positioning actuators are standard industrial parts http://www.ebay.com/...s-/55826/i.html
Batteries will cost you $200
A used Laser II - nice stable platform with a solid hull $500
So Doug - put your money where you rmouth is. For $1500 (ok $2,000) you could build this thing. Build it, and prove us wrong. If you really "believe in it" you can afford to set aside $100/mo for a year to fund it. If you can set aside $200 then you can have it done in 6 mos Remember that it will take you 1-2 month to find the right actutator and another 1-2 mos to write the initial code for your PLC.
Since the coding tools for the PLC are free (see the link) you will have $400 to spend by the time you need to buy one. By the time you are done with your initial coding, you will have enough $$ to buy one linear actuator so that you can experiment with it. By the time you've sorted that out, you will be able to afford all the LAs you need.
You will then need at least 2 mos to sort out the software for keeping it balanced (and you don't need a boat for it - plus you already have that "circular cockpit" hull sitting in your yard that you can use so you don't even need that. But lets say that went to the junk yard. So you have to wait for 2 mos to afford the Laser II or even a used Laser hull (or Force 5 or even a sunfish - any tipping dinghy will work. It will take you at least 1 month to design and build the track mechanism for the moveable ballastt (you can get used jib tracks cheap)
You then mount it on the boat and to sailing....
And if you can afford to set aside $300/mo, you can self fund this and have all the parts bought before you can use all of them. Look the programming isn't hard, you basically need only two sensor inputs: The heel angle, and the position of the weight. The first is a digital input the second is I/O from the actutator. So this is a fairly simple feedback loop. The hard part is the software. And that's just your time. no money involved.
See, you don't have to do a Frazer/Shaw 4.0 type build. Most startups self-fund the pilot. In the case of the Shaw - I suspect Frazier and Shaw are splitting the construction and materials cost and that it was built out of the spare cycles the Shaw shop had between paying gigs.
So you don't need to "raise funding" for this. Unless you are unemployed, if you truly believe in this - you can fund it yourself. I suspect you don't because you are scared it will fail and its easier to have the excuse of "I can't fund this myself" than actually doing it. So stop spamming this board with an attempt to sucker someone else into buiilding your dream project for you... Either you believe in it or not. If you believe in iit, you can sell some of your RC gear and basically fund this.
