GoPro Scuba Cylinder Mount

Hi there, I'm new here. I've recently found an entry-level 3D online modelling software, Tinkercad and have been Tinkering ever since. I'm into scuba diving and I've long wanted to design a GoPro mount for the cylinder to give a 3rd person view of me while I'm swimming about enjoying life underwater. (Think a less-sexy Lara Croft!) I wanted to run it past you guys to see what you think. I've attached 2 screenshots, because as you can see, the mount I've designed is collapsible, to save space in my GoPro bag. I've done the maths (Pythag) so each side is perfectly lengthed to create a right-angled triangle, with the hypotaneuse (long edge) is facing down my body, towards my feet, so that the camera view won't be obstructed. I've used a Pythag triple, so the arms measure 3", 4", 5". This was done for 2 reasons: a) It was easier to desine using these measurements and b) I don't want it sticking too far up from my cylinder so that it doesn't catch on wildlife/coral/divers. As this is my first GoPro mount that I've designed, I've had to go on deimensions I've found online for the actual hinges. I've settled on approx 3mm for each prong as well as the gap in between. I have actually shaved off .25mm from the middle prong of the 3-pronged-hinge, and left the 2-pronged-hinge at 3mm for the gap and prongs. I'm going to get the pieces 3D-printed by a local service I've found on 3DHubs.com, either in ABS plastic or in resin, though I'll probably go for ABS as it seems to be a bit more hard-wearing, even if it's not so detailed. In terms of mounting it to the tank, I will use 2 headstraps, with the over-the-top strap removed from each one and glue the plastic bits of each of them together, at the correct length of course. I would join them using a seperate piece of plastic and either a hot glue gun, superglue or even some sort of epoxy, whatever lasts longest in prolonged exposure to seawater. I would probably place it nearer the top of the tank, near to where the strap of the BCD jacket goes round it. Does anybody have any advice for me in terms of the design from a functional point of view as well as from whether they think it would actually get a good shot on the camera please? I look forward to your feedback, good or bad!

Pipboy 3000 SCUBA computer? Answered

I am a fairly avid scuba diver, I try to dive every other weekend, but I think I want a dive computer. It can calculate my pressure group, weather I do a multilevel dive or use a different nitrox mix. A good dive computer should also tell you your current and max depth, tell you if you are ascending or descending to quickly, include a compass and maybe even show you how much air you have left. It should also be easy to use. I also like Fallout (3 and 4 are the only ones I have played), and the wrist mounted computer that the hero always wears, called the pipboy 3000, looks like it would be the perfect dive computer. Not only could it be a dive computer, but it also may be a watch, or even an mp3 player while above water. Although the knobs, scroll wheel, and "RT" and "LT" buttons make using it seem more complicated, the size of the unit allows for a larger processer, allowing for a similar GUI as that of the "real" pipboy. Such a GUI would be able to display info in Standard English, such as "Set your nitrox % mixture." and letting you use the wheel to set the air mix that you will be using. I guess that having “confirm” and “back” buttons would help as well. The Geiger counter can easily be used as a depth gauge, which works, as the deeper you go, the more dangerous. The dive computer settings could be where the quest, world, radio, etc used to be, and you can have dive info and other things like reminders where your stats would be. The time could be displayed on the upper right side of all screens except the time screen, which shows the month day and time, which would be where your “weapons” usually are. Other time related functions can be used to fill the sub-sections like stopwatch, timer, etc. There could also be a screen that shows your limb conditions that you can switch to, just like anyone you meet in the game who has a pipboy, you see that screen. All this will have to be water resistant to maybe 70 to 100 feet, made of a hard metal, and fit comfortably. If anyone has any ideas on how to make and program this, or know of any job shops that can make and program this please answer. I know someone can do it, I wouldn’t know where to start looking. I probably made this sound much more complex than most likely is. I am basically looking for a diving computer that looks like a pipboy 3000 and is easy to use. I don’t really need an mp3 player. Again, if anyone has any imput on how to build and program it, or if anyone know any jobshops I can send this request to to have this made, please let me know. this is too good of an idea to forget about. Edit: Thanks to all who answered, And I think just the fact that it IS entirely possible is good enough for me, although price is probably the limiting factor. Thanks again.

How to create a safe DIY Snuba Apparatus

My Idea so far is to use an air pump (maybe one similar to the one that pumps up inflatables?) is to feed air down a tube to a modified snorkle mask with a 1-way valve going in, and a one-way valve feeding just into plain water.  The air pump would have filters and a catalytic carbon-monoxide filter/converter (w/ small heating element) in the tube leading down to the mask. The idea is that there is always a fresh supply of air running through the mask that there could be no deadly build-up of bad gases within the small area.  Included is a picture of how I envison it (minus the lame Microsoft Paint drawing skills).

DIY Scuba Tank (breath underwater)

I need some advice. I have a great idea that would be amazing if it worked. I want a small scuba/air tank whatever you want to call it (like a scuba secondary tank or a paintball co2 tank) that i can use to mess around with in a pool. I dont want to be constantly breathing, just enough to take a deep breath, go underwater and hold it for a minute, release air from the tank-take a breath, hold it, take another breath from the tank, hold it, and so on. Just enough to get a few breaths and be under water to last me for 5 or 10 minutes. The only thing is i dont want to have to fill it at a dive shop or from a tank that has to be filled at a dive shop like scuba secondary tanks. i want to rig it to fit a bike pump (which probably will not have enough psi to get the amount of air i want) or my air compressor. So i would like advice and also would i need an air regulator since im not constantly breathing? what could i use as a regulator if i need one at all?

Small Scale Scuba Gear within $100?

I had an idea for a good instructable. I'm trying to plan out on paper a neat breathing apparatus for a hundred dollars. Constraints are that it has to fit on the face, can be carried anywhere, and should at least provide one minute of oxygen. As a plus, why not add a pump so you can replenish the air supply when its running low. The way i might build this, ultimately, shouldn't be too hard. But what is being difficult is what to use to hold the air supply. would an air tank from an airsoft gun be any good? or would i have to use something different to contain the pressure? Any input would be greatly appreciated! -Jakit

How could I make an open circuit diving apparatus? Answered

For a quick summer project I always wanted to scuba, Hookah Style. Hookah SCUBA diving is basically diving without the tanks and with a surface line. Well I wanted to build one of these for my friends pool. First of all I wanted to build this all myself using store bought materials. I get the concept but I want to know two things. 1. Would A fish tank Airpump supply breathable Air, now I thought of this for two reasons, it is oil-less and If it is suitable for fish than it must be suitable for humans (fish are more sensative to that kind of stuff). 2. how would I build the mask, could I just get a half face mask and add an airline (inhale through nose, exhale through mouth) or would I have to build some sort of thing that works like a gas mask? Any Input would be wonderful! EDIT: I believe I will be using a small (oil less) air compressor instead of an airpump

Pressure Washer? Answered

I would assume it can't be, but it would be really lucky if a pressure washer could fill an air tank to the pressure the washer is rated for.  So can a pressure washer that says 5000 psi really fill a tank to 5000 psi with the right fittings.  It probably won't be breathable or paint ball worthy but is it plausible.

Artificial Gills

I don't kow about you, but I swim a lot and, as with most swimmers, would LOVE to be able to breath underwater without bulky air tanks or even a light rebreather. Fish take oxygen from the water so I don't see why can't I build something that does the same. Is there anybody who has any ideas or suggestions as to where I should look?

Use a Co2 regulator for air?

Can I use a Co2 regulator to regulate high pressure air.  I am trying to build a high pressure system using a scuba tank or paintball/airsoft tank to operate air tools, pressurize pipes, fill tires, inflate balloons, dust work areas and computers, etcetera.  There are C02 regulators but not many 'air' regulators.  I just want to use air and not Co2.

RE: One Person Submersible From Plastic Drum

The following is a quote of the post I've just left on the aforementioned Instructable (https://www.instructables.com/id/One-Person-Submersible-from-a-Plastic-Drum/?&sort;=NEWEST&limit;=40&offset;=40).  I would really appreciate the removal of this instructable. "Hi. I am a certified OSHA and CSAO commercial diver air dive supervisor, level 1, and qualified Master Scuba Diver Trainer with the Professional Association of Diving Instructors. This is a very dangerous idea. You might not die, but someone else might/will/and has. Just because there is a disclaimer there, you and Instructables will be subject to litigation. There is a reason that people need a certification to operate this type of life support equipment. http://scuba-doc.com/ageprbs.html "Because of Boyle's law, maximal changes in volume occur in the 4 feet (1.22 m.) closest to the surface and the diver sustains a tear in the pulmonary parenchyma with the escape of air into the pulmonary venous outflow." I can quote other resources, such as the US Navy Dive Manual and the DCIM manual, but it's Boyle's Law, not Boyle's "kinda' might happen. I don't know". "

is it possible to use a chamber capable of firing multiple shots before having to re-fill?

Is it possible to use a chamber capable of firing multiple shots before having to re-fill? cause the way i picture it you could use an attachment to the chamber connecting a independent pressure valve which in turn would be connected to the air tank. the fact that its self regulating would spare you having to fill up the chamber with the turn of a valve after each shot...but even so I'd need a independent pressure valve/regulator (small enough) that would shut the airflow at 100psi. and i prefer the pvc not blow up on me. i'd really like to try it but how and where could i find that type of valve that works similar to scuba equipment??

Swiss engineers build Bond-like underwater car

It is called the sQuba, and it is a car that runs on land, as well as in the water. Inspired by the Lotus Espirit, in the James Bond Movie, "The Spy Who Loved Me", the Swiss engineering company, Rinspeed Inc, was the mastermind behind it.If you are heading to the Geneva car show, it is expected to make a visit there.Read the full article at SFgate.com Company CEO Frank Rinderknecht, a self-professed Bond fan, said he has been waiting 30 years to recreate the car he saw Roger Moore use to drive off of a dock.The sQuba can plow through the water at a depth of 30 feet and has electrical motors to turn the underwater screw.You'll have to break out the wetsuit, however.The car has an open top, meaning that the two passengers are exposed to the elements."For safety reasons, we have built the vehicle as an open car so that the occupants can get out quickly in an emergency," said Rinderknecht, 52.Passengers will be able to keep breathing underwater through an integrated tank of compressed air similar to what is used in scuba diving.The sQuba's top speed on land is about 77 mph, but it slows down to 3 mph on the surface of the water, and 1.8 mph underwater.

Did you miss me?

You may have noticed that I mysteriously stopped posting for a couple of days. I've been camping! I came on as a last-minute substitute when another leader was unexpectedly hospitalised, and whizzed off to Gilwell 24 with a small group of our Explorer Scouts. It's an awesome event for teenage scouts - from 09:00 Saturday, to 09:00 Sunday, 24 hours of non-stop activities without the requirement of sleep.  Four thousand Explorer Scouts took up the challenge, and almost all of them managed a full 24 hours of extreme Scouting. 3G Swing Archery Bushcraft Zone Bouldering Campfire Climbing (Outdoor rock and revolving wall) Craft zone Crate stacking Disco Fairground Flying Trapeze Geocaching Giant games Gilwell gauntlet Global Zone - including Shelterbox High ropes course Laser Clay Pigeon Shooting Mountain boarding Orienteering Outdoor arena Quad Bikes Outdoor Woodland Quaser Raft Racing / Boat Racing Rifle Shooting Competition Scavenger hunt Scuba Diving Slacklining Speed climbing Segways Simulators Technology zone Water rockets Assault Course Car driving Go Karts Power Boking Inflatables Fire Building Fishing Military Activity Team Speed Stacking Caving Zorbing As well crafts and other activities going on all the time (I had my first go at wood-turning at 14:00, and was soldering together an AM band radio at 22:30 (goodness me, the writing on a capacitor gets small later at night!)). Add to that a month's rain in about 20 hours, giving liquid mud on the scale of Glastonbury, it's hardly a surprise that every single Explorer fell asleep on the train home. Because my standing-in was very short notice, none of my electronics were properly charged, but I did get a few snaps of the atmosphere before my iPod completely died. I have never been so wet or so dirty on a camping trip, and I was taking it easy - it's the first time I've been forced to pack my tent away wet and muddy at the end of a camp. If you're a Scout or an Explorer, and will be over 13½ next July, why not take up the challenge yourself? If you fancy taking part, offering an activity, or otherwise getting involved in next year's event, they are already taking comments and ideas.  If you're not in Scouting, and didn't realise it was so awesome (or that girls are allowed at any age), then why not think about joining? (As an aside, I'd never seen Rock-It-Ball being played before.  Looks fun.)
