How can I ease pressure from the solenoid`s tongue of an electric lock?

I have this electric lock (it`s a bit old) to which I connected to a video door phone, when the door is open, that is no pressure is applied the solenoid works fine, the problem is when the door is closed and  so pressure is on the tongue, when the release button of the video entry is pressed, the tongue is not pulled back so as to release the lock, it seems that it is not strong enough. Any ideas please ? thanks

Can a new lock need lubricated?

I had new locks put on my house.  A few months after they were installed, we had troubles getting the keys to unlock them.  I put some powder graphite in them and the locks seems to work fine.  I have been told however since the locks were new they should not have needed lubricated?  Is this true?  Or could the locks be bad and need to be returned?

Is there a Portable Door Lock that can be used for apartments, hotels, etc. that can be operated from outside the door?

I live in an apartment and the complex doesn't allow me to change the locks or install something permanently. What I would like to do is put something on the inside of the door that I could operate from outside. The whole purpose is to secure my apartment when I am not there but still do it within the apartment complex's guidelines. Any ideas?

Steamer Trunk Lock

 I bought a footlocker, but just can't figure out how the included lock works. I'll be using my own padlock, but it would be nice to have the built in one working, too.  The cylinder appears to be plastic, and the black tab above it unlatches the lock when pushed down. I can turn the key freely over and over, but it just never locks. Is anybody familiar with this type of lock that could offer some assistance? Thanks!

Arduino Music Lock

Had this idea for some time and ill possibly do it when i learn more electronics stuff. But for now, i'll share the idea! So imagine you have a secure locked door. Theres no keypad or keyhole anywhere on or near the door, but there is a microphone setup on it. The only way to open the door would be to play whatever song or series of notes that are programmed into the "lock" with a musical instrument. Since there are several lock-based instructables here that use arduino boards, would it be possible to use one with whatever required components to make a lock that opens with music as a key?

Arduino and a RFID lock? Answered

I am trying to get the arduino to know when a certain RFID tag has been read.(so it can be used in a lock application) I tried taking the code array variable and seeing if it was equal to the the what showed up in the serial monitor window with the program on the arduino playground page.  But it came up with the error "exponent has no digits" .  So what would I have to use so that the arduino can interpret the "code" array and see if it is equal to a certain tag? I know that there are already door lock programs out there, but I like to know how programs work so I can learn from them and apply that to future projects. Thanks in Advance! AI

Time lock box? Answered

Hey I've seen the movie city of ember and there you have a box that locks itself from the inside, only to open again once the preset time has expired. I'd love to make one for a friend of mine (and for me as well), who's always distracted during the examination, so he could lock his distractions away for the time needed. I browsed hours to find timers and count down circuits. the best things that I could find, never were longer than e few hours or a day. but for this project it should at least last a month. I got a weird Idea of hooking up egg timers in series, so if the first one ends, the next one starts, until your last one finished that opens the box (the more I think about it, the more it's sounding impossible to do) the next best thing that would simplify the build was an arduino, but since these are essentially tiny computers I think it would be a wast to just let them count down. (and doesn't a arduino consume a lot of power too?) and I would like to only use an arduino as last resort... you can make robots out of these little board, it would be too tempting to pull it out of my project and try to make something cool with it. would any of these idea's work descent? does anyone know what could be the best way to pull this off? thanks

The indestructable bike lock! ...Idea

The indestructable bike lock: the forum topic that was posted undeniably just to annoy the future patenters!So I had this weird idea for a product come out of nowhere. Y'know how aluminum is supposed to make cutting wheels on an angle grinder gum up, stick, and shatter - when trying to cut it, that is? I was wondering, what if a company engineered a special type of aluminum alloy or a similar material that would do just that: gum up abrasive cutting wheels and make them stick/bind and shatter. Then like with layers of plywood, it would be sandwiched together with hardened steel, in the shape of a U-lock bike lock, making it: Impossible to cut through with a hacksaw, reciprocating saw, TCT bladed portaband , because it's hardened and would wreck the teeth. Impossible to cut through with an angle grinder or rotary tool with an abrasive wheel because the aluminum would gum it up. Impossible to cut through it with bolt cutters - obviously... Impossible to freeze it with freezing gas? I don't know. I heard that's what thieves do. Maybe that aluminum alloy would be a super-insulator and wouldn't allow the hardened steel layer to freeze and become more brittle?I think it might just be invincible until the portable cordless battery powered waterjet is invented!Thoughts?

Frictionless firing pin lock

This is something I came across whilst working on my RBG just now. A blockade that stops a firing pin from leaving a potential gun which is nearly frictionless. The grey rod would be the firing pin. The gear placed close to the barrel ( grey connectors ) stops the pin from leaving the barrel, but it can still move freely very smoothly. Just thought I would share it with you guys. To think this came up by accident ;)

Password Security:Time delay lock

I've been reading about how easy it is for a computer to try 1000 passwords per second to get into your account. A human being could probably only try 1 every 10 seconds.  So why not put a timer on the gate?  If you enter the wrong password, you have to wait 10 seconds before trying another.

RFID/NFC computer lock?

I am curious if any of you have an idea for something that could detect a bracelet from 5-10 feet and when it leaves, issue a sleep command to a computer.  I think it would be relatively easy to issue the command from an arduino, but I'm not very sure on which tags and readers to use for the right range.  The idea would be for the computer to automatically sleep/lock when you leave the room.  So what frequencies/types of tags and readers should I look into that will offer a decent range, that is close enough not to loose connection reaching across the desk or walking a few feet across the room, but won't work from a few rooms down the hall, and will interface well with an arduino.

PDFs Lock up Computer

For days I have tried to bring up a PDF on any number of Instructables to no avail.  The page seems to be attempting the download, but then nothing.  However, in that process everything ... absolutely everything ... the mouse, keyboard commands, etc. ... nothing works ... FROZEN! Several days ago I went to Instructables for the first time in a couple weeks at least.  As soon as I tried to connect, my virus protection came up and said there had been an attempted attack on my computer which had been averted. I see much prior discussion about "bugs" and expect there may be some connection. I have only been a member about three months, but I certainly hope this bug situation gets resolved.  Had I read about the Instructables' website problem beforehand, I likely would not have shelled out the $ to join.

Suggestions. Locking threads, and suggestion forum.

(I'm positive someone suggested this before) I think we should be able to lock our topics when we want people to be able to read the thread and the comments on it, and don't want people to post on it (for whatever reason, everyone's would be different I'm sure.) One reason I could think of someone asked a question (pre answers section) and someone answered their question, and they don't want people posting on it (for their own reasons). They could click the edit button, on the edit page, their could be another button that says, "Lock this thread." Click that button would lead to a page that said something like, "Are you sure you want to lock this topic?" If they clicked yes, it would be a locked. If they clicked no, it wouldn't be locked. If they ever change their minds, they could un-lock it the same way they locked it. (Click edit, press unlock, and click yes, unlock) Thanks.
