electronic "key"

One more forum post and then I swear I'll take a break!!! I would like to build a sort of a "secret box," where access would be had through a sort of electronic "key." A few specifications: (1) the box would be permanently out of doors, and (2) the "key" would be simple enough that I could give interested parties the schematics and tell them to make one. I'm thinking a USB connection would be a natural, but I'm not an electronics person, so I'm open to all suggestions. Thanks!!!!!

Key Light

Ok so I used to have this key cover that had a tiny light, kind of like those crappy led key chain flashlights except that it actually fit on to the key. It would light up by pressing a button while trying to find the keyhole to put the key in. It was actually really handy.... I'd like to make one myself now that its broken but I'm horrible with electronics and would probably manage to blow something up without knowing what I'm doing. Can somebody make me an instructable for this?

Old Fashioned Key

I was thinking the other day about how I could make all of the gothy underclassmen even more jealous of me and my accessories, when I came up with the idea of having a giant, ornate key as my keyring. Kinda like in the secret garden, or some other old fantasy type movie/book. I couldn't find any starting points at the craft store, but I was thinking it could probably be made from wood, metal, or some type of sculpting medium. SInce it'll be a key ring and flopping around with keys in my purse, it will be rather vulnerable to dings and chips. Any ideas?

Key Fob for a Bicycle

Hello all! I'm going to be shopping for a bicycle here in a week or two, and based on a conversation I had with someone I'd like to know if anyone has done this, or if it's even possible: Making a key fob for a bicycle. Even though having a locking mechanism on a bike itself is a dumb idea I'd just like it for kicks. Y'know, after I've chained up my bike somewhere outside a store, turn around and "lock" it like a car as I'm walking away. Seems possible, but I just don't know how to go about this. Anyone have any ideas? Thanks for your time and effort!

Replacing laptop key

Hi, I have what can only be described as a "no-name" laptop sitting in the bottom of a drawer. Among other things it has a missing "G" key. The problem is I have absolutely no clue how to replace the key - I'm not going to pay for a whole new keyboard and the key + "springy bit" is long since gone. The only branding I can find is "Clevo M300N". I was hoping to buy a broken laptop and cannibalise it (there are other hardware issues, but the keyboard is driving me nuts) Can anyone give me a shove in the right direction here? (Sorry for rambling) Edit: UPDATE - I found the key, all I need now is some kind of spring or membrane to fix it right up!

proximity car key ??

Ok so I work at a car audio shop as an installer and I see so much different stuff and do a lot of custom stuff on cars.. Ive seen a lot of cars that are keyless.. its just a key fob. when you have the fob in your pocket the car knows you are there and lets you start the car with a push button... that stuff is at least 5 years old.. now the other day a new z07 corvette came in for work and the guy handed me a fob to bring it in the shop,, nothing new at first,, but as I approached the car I heard the locks click,, so I stopped and walked back a few feet and I heard them click again... this thing is unlocking and locking on its own as I get near and away from it... And it still gets better.. after walking to and from it a few times to confirm my suspension I finally opened the door... the dash was flashing and it said welcome technician. the key I had was a valet key.. the other key fob I had welcomed the owner by name... this is really cool... I needed both fobs because I was putting a remote starter on the car and both keys are required to program it.. the valet key I had also turned on the traction control and the car wouldn't go over 40 mph... that's a lot from just a key fob... NOW FOR MY QUESTION HERE.... Is this done with rfid or some sort of proximity sensor on the fobs?? I want to build one for my car but just for the locks and push button starter... but I want to retain the factory key also..any ideas or maybe a link to an instructable?? ive searched them but cant find one for my purpose.. lots of rfid stuff though..

Key chain multitool

I was thinking of getting a multitool that is small enough to fit on your key chain. Here comes the dilemma though... I don't know what tool to get. Leatherman has the squirt and the Micra. Other companies have ones as well... I was thinking of getting the squirt, but if I do, I cant decide if I want the P4 (pliers) or the E4 (wire cutters). Ahhh I cant make up my mind. Any help? The thing about the pliers and wire cutters is I don't have a set of wire cutters. However, pliers would probably be used more often. But if I need the wire cutters, I would wish that I had got them instead. Right now I am leaning towards the pliers, but...

Whistling key fob helps finding misplaced keys

key-less entry / key-less ignition (arduino based)

Hey guys, I want to make a key-less ignition and a key-less entry on my car. I have no doubt that arduino can be the core for this system. as of now, I am thinking of using arduino UNO to control everything and an RFID unit for the key-less entry. I know that there are many types of RFID, some for sensing close like tags or cards, and some for larger distance like 10 to 20 ft. the one I need will have to be able to read a module from around ten feet of the vehicle. I am debating whether to automatically unlock the vehicle when the module is within range or put a button on the door handle and trunk so that they will unlock if the key is in range. I decided that the push button ignition will include a toggle for ignition and a push button for start. The ignition switch will be wired through a relay so that the arduino can "enable" ignition when the key is present. I want all redundant systems so I will wire the ignition in parallel so the stock key will still start and run the car. I post this for advice, comments, and any improvements you guys can think of. My budget is $200 maximum. My goal is to make it for under $150. Any help would much appreciated. - Jordan

Controlling ServoBlaster with Keyboard Keys?

I am working on a project involving multiple servos, a pi, Servoblaster, and a short period of time left. What i was wondering, is that is there a "interface" of sorts for servoblaster that would allow me to control the servos with keys on my keyboard? I saw a thread where someone made an interface where you could switch between servo pins using left and right arrow keys, and adjust the servo with the up and down arrow keys. However, this could only be done one at a time. What i want, is to be able to control all 7 servos with 14 keys. Because of the lack of time (This is needs to be done before next week Saturday) i don't care if i have to access terminal with putty to control said interface. (A web page would be nice, but again, lack of time, and first i need the actual interface.) It really isn't an interface, i guess... I don't need to see what i am pushing/what is happening, so long as the servos move when the keys are pressed. I have a custom ./servod, which basically changes pin layout, and the max and min for the servos. Beyond that, ServoBlaster is vanilla. How would i do this? I haven't written any code for Servoblaster, nor any massive coding in general (I know basics of Python, nothing more.) Is there something like this that exists? Anyone have free time to make it? I am willing to try, so long as i am told what needs to be done. (Time is short, and i am busy. Though, i will still make an effort.) Thanks for your time!

Proximity key fob for motorcycle

Hey guys, I am working on a custom barebones motorcycle. I want to make the starting system incredibly simple by just carrying a keycard or fob that can be sensed within 4-5 feet of the bike which would allow me to just kick start it and go. I worked in access control before and to my knowledge the cards and fobs needed to be placed basically on top of a sensor to activate it, is there any way to give in just a touch more range? so just having it in my pocket would close the circuit and allow me to kick start the bike? wiring it in isn't a problem, I just need a switch that would sense a fob 4-5 feet away and close a switch. thanks!

Rekey a key-based electrical switch? Answered

I'm looking to make an enclosure for my 3D printer here shortly, as I plan to take it to a convention or two. While I plant to ALWAYS have someone I trust at the printer, I am thinking long term, and wanting to ensure that no one can mess with the printer while I am away (say for a snack run or to use the bathroom).  Either way, the enslure I plan to make is also planned to have a set of key-based switches. I would like all the switchs to use the same key, so I only have to keep on key on me to run the whole thing. I would also like this to be the same key that locks the access panel to the PSU and the actual printer itself, but I know that may be pushing it a bit.

The letters are typically used in model railroading. Clean the keyboard keys with a mild cleaner on a damp cloth. Wipe dry. Remove any partial letters with a pencil or ballpoint pen eraser. Apply the letters to the keys per the instructions on the package. A dull pencil works well. Lightly coat the key with clear nail polish. Should look like new and will last longer than the original.

How to emulate a RFID key, cheaply?

I've gotten into this nasty little habit of locking my keys in my apartment (twice this month). It costs me 20 bucks to get back in! We have a RFID key which costs 50 bucks to get a copy of!, There is no code on the back of it either. So, I figure, I'm mechanically inclined, I know how to solder, I can read electrical schematics, I understand diodes, caps, variable resistors, resistors, switches, leds, grounds...so on and so forth. I by no means understand it all. Anyways, I am rambling. How could I build a cheap (under 50) key emulator? Just to keep in the Jeep for when this happens again
