/diy/ - Do It Yourself

>>297741
Forgot to mention - when you wrap a cord or rope around an object 3 or more times, it holds 300+ pounds. It's called the Capstan Effect. Any less that 3 wraps, or "turns", will not support bodyweight. I suggest using 5 or more, but no less than 3.

I'm going to save you alot of time and energy that would have been spent on research.

- Use an emergency rappel belt (aka rigger's belt) for a lightweight, easily concealable make-shift harness

- Use 7.5mm technora cord. Firefighters use it to as personal escape rope. The cord is rated to 4000 pounds and is heat resistant up to 900F. Any rope/cord bigger than 5mm can be gripped by the human hand.

- Use professional climbing carabiners.

- Only use the grappling hook to climb. When you climb to the top, you can retrieve your hook. If you're rappelling or swinging, you can't. To solve this problem when rappelling, tie the rope down to something that WILL hold your weight and cut the cord from you when you reach the bottom. For swinging, use fishing weights and wrap the cord around the object that will support your weight at least 3 times. Cut the cord when you land. Keep a pouch of at least 10 weights on the belt.

- Use a climbing carabiner with a spool to hold your rolled-up cord:

- Bring a monocular or binoculars to aid in visual verification of a secure hook.

- Gloves are a must

- In "hot spots" where it's likely you'll run into trouble or otherwise need to ascend quickly with no time to prep your hook, case the area out first and place rope ladders at high, tactical spits. Roll them up and rig a pull-string to them so all you have to do is pull the string, and the ladder comes tumbling over the side. Secure the bottom of the ladder to your foot so nobody can climb up behind you.

- Leave caches of extra rope, weights, and carabiners hidden on certain rooftops - just in case a resupply is needed.

Nice piece of info on shear-thickening/non-newtonian fluid >>290141

Nice tidbit of info concerning shear-thickening fluid >>290141

This is easily the most useful piece of information i've found on the subject aside from initially learning about shear-thickening fluid. Thank you!

This. Let's see more of this.

I wrote up a brief essay on possible suits at supersuitforgood.wikispaces.com to get people thinking...

Moar like Atlas.

I'm thinking not for OP, but a useful thought.

>>288683
>what rope will you be using
Not OP, but for OP I suggest 7.5mm technora rope. It's what firefighters use as a "last line" escape rope. Anything bigger than 5mm is big enough fot a human to grasp, and it's weight-rated to 4000lbs. It's just low stretch, so dead-drops are going to hurt...

>>288641
have you considered Spring loading your gun or using a crossbow?

Not sure, at least I'VE never worked with "eyeclopse".

This is all I have in terms of night vision, but it works!

New thread about stab-proof armor has good links concerning shear-thickening fluid - how to make, principles behind it, etc.

Good points. What about slash-stab resistance?

I'd agree that vehicles are largely a problem - but i'd suggest something off-road capable. As far as ID and/or plates, you COULD rig it with a pull-wire or remotely via electronics, either way i'd suggest a flip-panel that you secure two plates to - one legit, one a decoy, and just flip them when you're out of sight. Obviously the primary goal would be not to get caught, but realistically there's a huge possibility you'll have a run-in with police. You could also rig oil-slicks or caltrops to deploy via push-button or pull-cord, but i'd assume you wouldn't want to hurt anyone but the original criminal(s) you were persuing. There are many more issues with vehicles though - heat signiature, sound, lights...just a bigger target such as a vehicle is a higher profile, so you probably WILL be noticed in any vehicle.

>>285773
That's partially what the monocular is for in the detective pouch - to aid in visual verification of a good hook. For situations where you are unable to see the hook's target at all (obstruction of vision), i'd pull it tight to make sure it's latched to SOMETHING, then climb a foot in the air and really tug hard on it a few times, then start climbing. There really is no surefire way to ensure you'll grasp something sturdy - but part of vigilanteism is balls. You're already putting your life on the line. There are going to be risks involved that could cost you some very bad pain or your life - seems like this is one of them.

The link I have is banned from here (i was suspended for 3 days for posting it before).

Go to supersuitforgood.wikispaces.com and look up the utility belt there (should be a link in the right-hand margin) - I have links listed for all the equipment i'll be using.

>>285755
I agree with >>285758

You wouldn't be a "villan", just an anti-hero. It's all the same to cops, though.

(concluded)
And here is a picture of the new pouch side-by-side with the old one. With this new pouch, the squishing issue is eliminated. These new pouches are the perfect size!

>>285747
At supersuitforgood.wikispaces.com, I included a FAQs section for the belt. At the end are things to consider when building your belt.

As a side note, good luck getting a pi any time soon - i'm hearing the waiting list is very long now. That's where i'd start - raspberrypi.org.

>>285752
The cord that will be used should be thick enough for human hands to grasp and climb. Otherwise, you can use acsender lanyards, an autoacsender (personal winch), or if you have time to set it up, rope ladders with pullstring access. Does that answer your grappling question or did I misunderstand?

>>285732
Not at the moment, but you can contact me at lucassparda@yahoo.com for now. I'm currently computer-less and have to rely on my phone for internet, so it may be a while before I get some kind of IM program up and running. On the plus side, I always have my phone, so i'm pretty much garanteed to reply within 15 minutes (unless i'm sleeping).

Thanks for the praise, btw - I don't get that too often concerning this project. Speaking of, pic related - those were the old pouches I ordered that were deemed 'too big'. As you can see, they pose mobility issues as bending your leg would squish some of those pouches...(continued)

it depends on the type of batteries, but my problem with 4xAA is size and weight. I'm going to try my luck with various lithium batteries, like for iPod or maybe a cell phone battery. if need be, i'll use something more powerful than necessary and use some resistors to dumb the volts or amps down.

As far as concealing the belt - I think I remember you from my previous threads - you can try wearing a backpack as the pouches in the back may look like they belong to the bag and not your belt (the pouches on the back, anyway). Other than that you can try wearing baggy clothes and a long-bottom shirt to conceal the pouches. Personally, i'm keeping mine in my trunk. This question could use a better answer - does anyone else have any ideas?

>>285061
This was me, BTW.

My Utility Belt design is featured at the site I linked before - made some changes since the last Utility Belt thread. Medic pouch is still under construction, though, and I have a trained first responder assisting with the reconstruction - so the effectiveness of the pouch should sky-rocket.

>>276857
-also bring a lockpick set for "questionable investigations". Self defense will help in this area, too - as will stealth amd sneakiness.
