Originally posted by 91RedBigFinZ Oh, and for some reason the title of the post is fingerprint ignition.. when it should be fingerprint entry system. My bad, I was thinking ahead of myself i guess.
Next Project, right! :sillylol: Again awesome job!
if you are storing the whole print.... what happens if you cut the finger that you programed into the system? do you not drive your car until it heals, and hope it doesn' t leave a scar?

you can program what did he say 20 or 200 fingers into the system. put all ten in there just in case. then others that you trust. am i right here?

I'm sure if it was ever produced commercially (and perhaps this is already true of it, I don't see anything about it in the other posts), it would have the ability to store at least a small handful of valid fingerprints. Say, you could store your right thumb, your left ring finger, your wife/sig. other's left thumb and right index finger, a mechanic's thumb if you ever have to take it to a shop (I assume you can clear the memory at any point)... etc. Enough storage space to store those who tamper with it (as suggested earlier) would be way too much, but surely the system would have enough for at least half a dozen valid prints?
(edit)
First, brody beat me to it. Second, I found the post that says you can store 200 prints.
Dewey316: Actually, the point of memorizing the entire print is to make it recognizable when it is wet, dry, if you gain or lose weight, if it is dirty, and if it is cut. Of course, if it is cut so badly that you have stiches or something it probably wouldnt work.
brodyscamaro: yes, 200 prints can be stored. The more you have in there, the less chance of being locked out if you get some of your fingers cut off. If you lose all 10 fingers, I don't think you would be driving.
spike1856: yes... what you said. yes, the memory can be erased, and you could just give the mechanic the key if you didn't want him to mess with it.
You mean to tell me that thing is real? KRAP! You know that would sell. You can probably make a load off of that! The new keyless entry system for the year 2005!!!!!! People will start cutting fingers off to rob carz!
DAM EE's! hehehe beeing a frosh. engineer...(went in as a ME, gunna go IE) i love to see engineers shapping the world! ahahahaha! cant wait till my turn

Intellectual property is a bitch ain't it Awsome job, an A+ in my book. Im curious what the rate of "try and fail" for the recognition is per 100 tries with a person that has no experience using this device. do you try a few times till you learn the pest way to place your finger and pressure to avoid distortion of the print? would a person with no experience when tasked to try it, fail to open it say the first 5, 10, 15, 20 times they ever tried even if the print is a saved/regonised/allowed one?
From an EE major point of view, this kicks ***. EXCELLENT job there While I don't think I'll be doing this to my car anytime soon, if you have any more info (schematics and such) on the system it'd be cool just to take a look at it sometime
What class did you do this for? im pretty interested in it and class scheduling is coming up....i just dont think my college has such an awesome program. anyway thatd be sweet just to know how to wire stuff liek that.
Congratulations on graduation. Interesting project... I may have to get that fitted to the doors when I build my KARR replica (KITT's evil "older brother" from "Knight Rider"). Next step, as somebody already said, has gotta be fingerprint ignition...
Have a good one, everybody. Gotta go tangle with my Speech prof...
__________________ To err is human. To forgive is NOT STRATEGIC AIR COMMAND POLICY!
91RedBigFinZ, I remember reading that they used some kind of special gel that solidified enough to place over your finger. Something very thin. The only thing they did was picked up a glass that someone just drank from, put their gel covered finger directly over one of the prints on the glass and that was about it. They went to one of his fingerprint security devices and it worked. Last I heard is that they tested the "gel trick" in a lab over and over and have about a 98% accuracy with it.
Anyway. I really don't think anyone will ever have to worry about that, lol. I don't think anyone would ever want to go through that much trouble to steal a car.
Once again, great job. Heck, if you ever sell these I probably will buy one.
B4Ctom1: From my experience, experience is everything. Even with one print stored, I almost never get rejected. The reason is because I know how and where to place the finger, but most importantly - I am consistent. Doing the same thing every time will allow access nearly every time. New people usually get rejected at least once, but then I remind them how to place their finger on the sensor, and they get verified every time. The learning process isn't rocket science, and consistency is more important than method.
HamSpiced: I am doing this for a senior design project class. Actually, my major is Electrical Engineering Technology. We get to choose our own projects, design build and test them all in a year-long class (although I did mine in one semester) People do everything from amplifiers to telephones.
Charyou Tree: From the time the finger is placed on the scanner, the doors are unlocked in 2 seconds or less.
Holy ****!!! :hail: That is the coolest thing I've ever seen!
As for patents, I do know that if you can produce something similar, yet performs the same function, you should be able to patent it. Of course, even if the university owns half the property, I don't think they would object if say....GM or someone offered a substantial sum for the idea. If they where not willing to share the money, I'm sure some legal persuasion would change thier opinion. After all, you designed and built it.
That aside, congrats! I would be among many people who would love to own a car with that on it, and if this is a sample of what you can do, I expect a very prosperous future for you.

A company owning your designs can get pretty tricky. My great grandfather was one of the pioneers of the "hypospray" they use in the military today. He never got one red cent for his invention. His company said he made it at their facility, so they owned it.
I've two comments equaling $.04 so let's round to a nickel.
Well, I know that you have hopes of creating and designing a fingerprint ignition system, which is a great idea. However, DOT madated that there MUST be a key for the ignition in street cars. I think it was the 50th Anniversiary Corvette that wanted to have a keyless ignition, but the DOT would not let them do it because there was no key. I can't remember the source exactly, but if you really want to push your idea, then jump on DOT's back and hassle them. GO FOR IT!!
The other point I'd like to make is that I feel the first place to start marketing your system would be with the supercars, and not the average cars. With the pattern of developments, products have been made and used for a small number of people highly regarded, once they give their praise, the public starts playing with the new product. I would start out with Lamborghini and Ferarri before you knock on Chevy's door. Of course that is my personal opinion, so you can take it for what it's worth.

thats fine, I like that point about the key and the law but if that system fingerprint ID system was simply slaved to a "VATS" style system, you could have a key and just leave it in the ignition.
neat idea. I could have used it for news years. I got locked out of my car. Didn't have my key to open my door .
A friend had to take me home to get my spares..
I would buy one.
should take a poll on it and give it to your teacher for class.

Wow, this is all very interesting. If this was my project, I would be pissed if I didn't get an A. I won't be surprised if in a few years something like this will on more expensive cars like a jag or a bmw. Nice job.
SuperchargedRS reminds me of a friend of mine, always trying to rain on the parade! Damn man. Anyway, bottom line, if someone wants something, they will most likely find a way to get it. I've seen it before. You can definately detur them, but yes, there could always be another way to steal something. I still think its a great idea though.
Well, not much is new. I won the second place award in my graduating class for the project. I haven't really thought about it since then since I am low on funds/time right now. I got a job, but have debts to pay off - so in the future, I could possibly start this up again.
On another note, my job is with Delphi Automotive and I am a validation engineer. I run tests on Delphi's products for: Temperature, Humidity, Moisture, Vibration, Altitude, Salt Fog, Salt Spray, Car Wash, Submeresion, and even a dust test. Its pretty cool and i could use my knowledge to make the fingerprint entry system more rugged.
with being envolved with delphi, were you working there when you made you class project? if so then you have overlapping claims on your intellectual property, its rare but it looks like either one could rape you of your idea. the school or delphi P.S. send me some delphi injectors 36 pounders

2003 Dodge Viper has a keyless ignition. I read this in Motor Trend magazine this past year.
If your not going to pursue it, i bet you could make some major money just by selling it to Ford/GM...Although it sounds like something that should be on a Lexus, or my Camaro...
Congrats on the job! You feel like it helped out a lot getting hired? I'm in the process of finding an engineering job right now but not doing as well as you did.
:hail:
Do you know how many of these you could sell to us KITT conversion guys?? You could make a killing on these things if you can get the design for yourself.
Excellent invention without a doubt.

__________________ "Do or do not...there is no try"
Now if I could get that hooked up to my shaved door handles, then i could just put my fingerprint on there, and activated the door poppers and bam, my door is open....
Seriously dude, let us know the SECOND you are planning on selling these on the market, I would buy one from you IMMEADIATLY....no kidding....
i find it cool, simply because ive never seen anything like it before. I would love to try something like that.
so let me try to unerstand how this works.
the fingerprint scaner turns "on" when the trap door is lifted, scans your finger using your finger to complete the circuit( do all fingerprint scanners do that?)
then it sends the data back to the processor, which looks for a match in its memory (non-volital ram? [NVRAM?]) if a match is found, it sends out a 12V signal to door actuator, and then the rest works like a standard remote keyless entry? plus the led's which i assume are turned on with "if" "then" statments
what program is it written in? qbasic-ish?
and where would one acquire such things as a fingerprint scanner??!?
Originally posted by soulbounder I really like the idea but I don't believe it's practical. I wouldn't think it would be any safer than a normal keyless entry/power lock system.
Yes it is safer AND more practical. Think of it this way, now-a-days you have to use a key fob to do a remote entry. Now, if you loose or break it you need to get another one and have it programmed for your car ($80 is the going rate I believe). If someone steals your fob they have unlimited and easy access to your vehicle. The fob uses batteries which can/will die at the wrong time. The fob, even though small, still takes up space in your pocket.
With this system you have eliminated all of those problems.
And locks are only to keep honest people honest. If someone wants ANYTHING of yours badly enough, they will get it.

if i remember right the Viper had/has a push button start. along with some other exotics.
that is awesome !!! it would be neat to tie that to a shock sensor so if somebody knocks it sets off the horn or siren.and or tie that to a remote start(automatic car starter).so the engine is running before you get in the car. or interface with the onstar system so if somebody tries to get in(so many failed attempts) it calls onstar and lets them know of a attempted break in. or calls a pager that is on your side.:hail: :hail: :hail:
Well, the project still works after all of this time, but is a little dusty now. I test it every once in a while to make sure it works. I haven't explored improving or producing more of the units, but I am sure I could do that. The problem is installing the sensor itself, which for this project required cutting a hole in the door. I am not sure of anyone, including myself, who would want to do this to thier car. I think about it every once in a while, and I even read an article about how this will be coming to cars of the future. Im glad everyone is still interested in this - its good to see people respond to new ideas.
