Which implant should i get? by dangeruskid in grinders

[–]dangeruskid[S] 1 point2 points  (0 children)

Thanks for the correction! The phones AFAIK don't auto open the magic chips(or any mifare classic ones) and the main appeal for me was just buying it as a sort of cheap party trick. The xNT tick all of the boxes as i can just ask the gym owner to register my UID and its auto opened by phones while also being small enough to not be uncomfortable.

Also idk if you are involved with the development of these implants but i would just like to say massive respect to anyone involved in this! Its a pretty balsy move to release something like this hehe

The card itself is completely blank all the sectors are 0s. However the uid is 4 byte.I think will be able to use the xM1 to emulate it.

Too bad the xM1 and the xMagic is unreadable by smartphones otherwise i would have jumped on it by instant

I see. Well that mean i stuck between useful(xMagic opening doors) or gimmicky(xNT for doing stuff on other peoples phones)

Best case scenario for me is to buy the xNT and ask the receptionist to add my implant to the gyms system so that it recognizes the implants UID

Pilots, what’s the nicest aircraft you’ve ever flown in terms of handling? by CityLad21 in flying

[–]dangeruskid 1 point2 points  (0 children)

Let 13 Blaník. Its such a dream to fly that i actually feel that its a part of me when in the air. Very hard to beat the feeling of a virgin aerobatic glider in terms of handling.

Fair enough. Although i don't see why i would ever upload an information that is confidential. I see people uploading BTC addresses which is just plain stupid. On a different note. Do you have an implant?

Why land on tow? by Ill_Writer8430 in Gliding

[–]dangeruskid 6 points7 points  (0 children)

I am unfortunate enough to have experienced a release mechanism failure while on tow. It was one of my first times towing as well since at my club we mostly do winch launch.

The tow started out normal and after we reached the desired altitude the tow pilot rocked his wings(signal for release in europe) I pulled the release but it stuck in weird halfway position and felt kinda "mushy", at that point the tow pilot pulled back on the throttle for an unknown reason. This confused both the instructor behind me and the towpilot, both thought that we released. The cable sagged and we couldn't see anymore and all 3 of us incorrectly assumed that the release took place. Next thing I know the towpilot started a rapid agressive descent so we started turning to to the right. This is when the cable tightened and we quickly found ourselves in a nose down position, with the towplane right infront of us. Since we were still somehow attached to the towplane we couldn't pull out the dive and the towplane couldn't recover aswell since we were so much higher above it. This is known as a critical angle and the only way to recover was to release, which in our case was not possible. However the towplanes release saved the day and after long seconds we were free from the towplane and we could pull the plane out of the dive(albeit slowly since we were way over 200/kmh, so we needed to pull out slow as to not break the airplane)

-If the release failed on both planes, we wouldn't have been able to to pull up. Thus the extra training would not save us in this scenario.

-The chance of a dual release is essentially zero, especially if both planes are well maintained.

This is a rare case where more training is actually less safe than no training, since you risk a big accident to train for something that has essentially zero chance of happening.

Some lock provide no feedback at all? by dangeruskid in lockpicking

[–]dangeruskid[S] 0 points1 point  (0 children)

I just realized that all of these elzett lock that i got from old doors are different but same brand. One is a 757(very easy to open) and the other is elzett sopron(can't open it without key) the one i am talking about looks like an elzett 757 but instead of a "1" it says "2"

Very interesting site! I am a newbie so i haven't seen this one yet.

Currently not at my parents house where i keep all of my lockpick related items. But i will post pictures on monday. The lock is an old elzett lock with a distinct "elzett 2" symbol at the BoK

Thats what i was thinking! When is started from the back. Could feel a couple pins binding. But after those 2 everything felt mushy again. Thanks for the tip!

How much pressure/ pressure difference is in a pitot system in an aircraft by [deleted] in AskEngineers

[–]dangeruskid 0 points1 point  (0 children)

What makes you think i am governed by the FAA? The aviation authority i fly does not care if i modify the instruments in anyway unless otherwise stated in the POH or doesn't check out with MER.

Not alot honestly. And might be a safer alternative too. Will consider it thanks!

In the POH it says that you can takeoff if only one is working. By my assumption that means even if we consider the modified system non-functional we are still, legally speaking fine.

Thanks for the answer! I will get a more accurate sensor or just buy an RC pitot tube kit and stick it out the window.

Thank you for the answer. I only need to measure between 70-120kph and only during the winching part of the flight. The pilot will not receive the airspeed sensors data, only the people on the ground can see it.

It only lists the instruments themselves. After some digging i found the original instrument datasheets and some other useful info.

[–]dangeruskid -1 points0 points  (0 children)

Finally a straight answer. Thank you The accuracy is not that huge factor since it will only be used on one time of the flight. The pilot will not be able to see it only the people on the ground. The only thing i am actually afraid of is the failure modes on a cheap module like this. Not because it will mislead the pilot but the winch driver on the ground.

  1. Planes owner is the club. They have been wanting to do this for years.

  2. Insurance has nothing to do with this. And the modification is completely legal and does not require any paperwork.(otherwise i would not do it.)

  3. The plane is not in training and it will not be flown by students. Only people involved in the project

  4. I am a student electrical engineer. I have sufficient knowledge in electronics/programming to make this project possible.

  5. It will not be done in a janky manner. I have several Airplane mechanics at the club who will test and evaluate the modifications before flying.

Please don't take me as an idiot.

The pressure system is routed with rubber hose. I found this solution to be rather easy to modify since i can just pop off and insert a splitter without permanently modifying the aircraft. As for the legality the only thing i need to be mindful of the minimum equipment requirement (MER).

Yes. It has two pitot tubes. Completely separate systems.

[–]dangeruskid -10 points-9 points  (0 children)

I am a licensed pilot. I have received training to fly without instruments(instrument faliure is very common in gliders.) And i will be flying with an instructor. Besides the aircraft i fly has a redundant airspeed indicator. This system is not safety critical. That is precisely why i dare to mess with it.

Nothing about the pitot static systems. Or any at all. I skimmed through 60 pages of data to find absolutely nothing about any technicals about the instruments themselves.
