LED Sea Urchins

These glowing sea urchin shells that the folks at Evil Mad Scientist Laboratories put together look pretty sweet and are really easy to make. It all boils down to this: LED throwie + sea urchin shell = glowing sea thing! Simple and effective. Nice. Quick project: LED-lit sea urchins

Computers at/near the sea? Answered

I am living 100 meters from the sea which results in high humidity from time to time. Got the message this morning: CPU fan has failed. Discovered  a lot of moisture inside my pc and the dust in the fan has become muddy. We had a lot of rain and mist of late.  What does the people on ships do? And others who live this close to the sea? I would really appreciate ideas on what to do to prevent that from happening again.

Found a REAL Sea Turtle in a Dumpster?

I was at the beach a few days ago for a school field trip/ biology class. I'm always searching for material for projects, so I figured that while I was waiting for others, I would take a look, as something that looked like a motor caught my eye. It was just a rusty motor, but on the way back, while walking near a dumpster, I spotted something HUGE inside.  A REAL SEA TURTLE IN A DUMPSTER? I didn't know if it was real, but: There was no smell - no flies and bugs too. It's either a fake turtle, or has died recently.  The shell was peeling. The shell of a tortoise is in one piece, but the shell of a turtle is different? The head looks like it has been connected to the shell. I don't think that means it's a real one. The rear left leg looks just so real. If it's actually real, I would think that someone spotted it, dead, on the beach, and called the people that deal with that stuff. I think that it's pretty unlikely that the turtle fell in, as it would have probably landed upsidedown, and because it's pretty far from the swash (?) zone, even though I know that can travel way more than that, probably even uphill. Pictures below. What do you think? ᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴬᴴᴴᴴᴴᴴᴴᴴᴴᴴᴴᴴᴴᴴᴴᴴᴴ

How to operate a brushless motor (without complex systems)? {Sea Scooter Project} Answered

I'm trying to make a mini "sea doo" sea scooter for under 100usd.  Im wondering if its possible to run a brushless motor with a simple switch rather than a complex arduino based system.   I will probably enclose the project in a 4-6in diameter pvc pipe with end caps and run the propeller shaft through a smaller pipe with 2 bearings on both end to keep water out.  I would prefer to have a hand drill style switch for variable speeds but if that's not possible single speed button will work also.  Also are li-po batteries a good option for this.

Is this on the markety already? (Man over board localizer)

MAN OVER BOARD LOCALIZER The system consist of a ballistic launched lifesaver with a flag and dye marker combined with an alarm. The system is simply a can of pressurized air that is being rapidly released (or an automotive airbag explosive unit), pushing a lifebuoy into the water, towards the person in the water. Additional features: The system should also have a high flag or maybe even a balloon, making it easier for both the person in need of rescue to swim towards it and for the boat to find “the spot” where the person fell overboard. This is harder than it seems, especially far off shore, where one square mile of water may look very similar to the next one. A slow releasing dye marker for the same reasons -also makes it easier for air rescue to find the spot. For big ships, a control panel that asks you to point the “lifebuoy barrel” towards the direction where the person in need of rescue is. This way, the ship would have six units pointing in all directions. Pushing the control button should also sound an alarm GNU License by Einar Kramer

60m floating sea conveyor as customer transportation to/from a deck 30m offshore. Can anyone give me some advice pls?

The aim of this creation is to assist weak/tired swimmers.  The platform (used for watersports) is quite far from shore (30m) and even with lifejackets I don't want anyone getting in trouble or drifting off.  I do have a boat for emergencies but it's too small for regular use   Anyway, I was watching a ski lift and thought that the principle should be applicable (in theory!) to my problem.So far (not very!) I thought I could use waxed nylon rope with floats placed approx every 1.5/2m for people to hang onto - the bit I have no idea about is how to get it all around the mechanisms which power it ( "mechanisms" because I can't remember the names, I really am a beginner so pls go slow!).  Also a bit vague re marine engineering considerations (type of materials etc) and power.  I know I haven't got very far but someone could pls lend me a bit of their brain it would be much appreciated.  Simple and not massively expensive would be a big relief!Thanks again for reading this,Kate

Underwater Jetpack Project. [HELP NEEDED]

Im planning on making an underwater jetpack something like this. However I'm a bit to dumb to figure out all the ESC and electronic components of brush-less motor systems.   Im also limited because this is a school project and in order to be reimbursed the materials need to come from amazon.  I will be using it in a chlorinated pool for demonstration but salt water resistance would be nice.  My requirements are as follows:  1.  Propeller must be covered as I may do another project after this one that requires fingers (im thinking 6in diameter pvc pipe with chicken wire or a metal grill over the ends) 2. Modifiable for different circumstances.  (I already cut up an old backpack and screwed a plywood board to it for mounting the propellers and  batteries, however I may decide to go with hand or foot mounting instead.   3. A trigger operable switch. (Cordless drill style although I don't care that much about speed control.   I'm planning this project to be for a senior year high school project (next year) so I have plenty of time. Do you guys think something like this would work for the propellers?  Their for air so I would expect significantly reduced performance in water.  However if they are to high rpm/low torque to spin properly in water perhaps I could keep the enclosure and switch out the motors for higher torque ones.

What material can be used as a binder that would slowly dissolve in sea water?

There is an on-going problem in the fishing industry concerning bait in the crab fishery. Bait is becoming almost as expensive as crab. At the same time, there are by products in the seafood industry that are just being wasted that would fulfill the required needs if it could be combined with a sea water soluble material that could be adjusted to dissolve within set periods of time such as 3, 5 or 7 days. Anyone have any ideas? No soap or any material that would disturb the natural balance of the environment would work.

Minecraft Pigs, Sea Creatures, Blueberry Hair Barrettes and More at Knox Makers @ InstaMorph Build Night

Members and guests of Knox Makers had a great time experimenting with InstaMorph during our Build Nights. First, we tried using InstaMorph with heat guns and magnetic metal shop trays because that is all that we had at the time. We figured out a few important things pretty quick: Metal gets hot. Metal heat guns stick to magnetic shop trays. InstaMorph sticks to EVERYTHING. This led us to important realizations: We need olive oil. We need to avoid magnetic shop trays for this purpose. Through experimentation, we figured out that putting colored thermoplastic pellets on top of InstaMorph projects and then gently heating can cause cool effects where the pellets melt into the InstaMorph in wild and beautiful patterns. We had fun creating sea creatures together, everyone felt comfortable diving into their own projects, and we even used the InstaMorph to craft our own set of tongs for crafting InstaMorph, because meta. We broke down and got hold of a digital induction warmer and pan made for it. This made things go more smooth. Or rather, more safe. We found out that the InstaMorph does OK at the recommended temperature at our sea level (approximately 265 meters elevation above the sea level), but it cools and hardens VERY quickly and is difficult to work with. Most of our participants actually seemed to enjoy the more dangerous heat fun method more than the digital induction warmer method. We did not try other methods and we suspect that noninduction water heating would have worked a little better. We had multiple Build Nights with the InstaMorph to give plenty of people in the community time to toy around with it and come back with their own ideas. We also had members and guests experiment during our Open Hack Nights and at other times. In all, we had a blast. We ended up with 8 different tutorials out of it all, and you can check them out here in this collection: We may add more over time, depending on interest. Thanks for reading!

Coffins, bedstead and idiot rescued by lifeboat.

Sometimes I wonder how we earned our reputation as a seafaring nation... A DIY sailor had to be rescued by the Lyme Regis coastguard and lifeboat after taking to the sea in a DIY yacht consisting mainly of two coffin-sized plywood boxes and an iron bed frame. The anonymous man had spent several days on the beach, lashing his vessel together.  It was so obviously unseaworthy that the coastguard and lifeboat crews warned him not to put to sea. Unfortunately, he did put to sea off Charmouth.  On an out-going tide in an offshore breeze. Within yards, onlookers had to call emergency services, and the lifeboat insisted on towing the (for want of a better word) boat back to the beach.  The captain had been unable to make headway against the breeze with his home-made oars... I've got to wonder... how many of our own authors have been in a similar situation? (You get all the serious news in the Daily Mail...)
