Question by katiecannon    |  last reply


Hello, can anyone help me design an RFID reader which can tell me when something is missing. I would like to build a reader for my file cabinet. I know this is hard but the reader will have to keep reading the files by maybe pinging and when a file is missing from the cabinet an LED will light up and maybe a small readout telling me what file is gone. Cabinet is small only 300mm so if anything is more than 300mm away from the reader it will light up. Can anyone help?

USB reader for gameboy

Does anyone know how to program? It would be cool to install a USB port into a gameboy cartridge so that the gameboy could read the files and/or play music on it. You would also need to put that code/program onto that GB cartridge. If anyone has any ideas, feel free to speak up! :D -cwix09 also see my related post

USB reader for gameboy

Hello! Have you ever needed to transfer a file on one of your USB drives to a second usb drive and dont always have a computer on hand? Sucks doesn't it.. I have an idea to build two usb ports into some kind of device with a screen so that you could transfer files. However this would require a skilled programmer and I am not that. So I was wondering if anyone had any suggestions. It would be cool to incorporate a gameboy and perhaps make the gameboy into a MP3 player as well. Just sayin: it would be nice if things like kindles or ipads had usb ports! (thats for any apple employees who may be reading this lol) -cwix09

That is, the bluetooth enabled finger print reader would store one finger print and then compare the person usign the reader to the print stored. If the prints matched it woudl send out an approval code. I am sure someone out there could make one. How can I contact that person?

How to reprogram this NFC reader?

So I've got this NFC mobile banking from work (we've shut down the system because of lack of users) and we were left with a few hundred of these "read-write" NFC things. As you can see from the photos they have 2 SIM-card holders (probably that is the way they were connecting to the network) 2 USB mini ports, a RGB screen, a small speaker, and the board which is made of 2 easily disconnected parts. If I try to connect it to my PC it gets stuck on "Time and date set" and after a minute it writes a "Failed" on the screen. What i want to do is to make it able to read/write NFC chips and to display text on the display. Please help me because I have no idea hot to do this.

Interfacing the arduino with the parallax RFID reader? Answered

I want to interface the parallax RFID reader with the arduino.  I have done some research and found some programs, but I can't quite understand what is going on it the programs.  Here is one that I found on the arduino playground: I couldn't paste the code, because when I did it just went on one line, but the program I looked is the first one. The questions I have are: char code[10] ---- what does the 10 mean? Also how does the program read each byte individually, and then combine them into the whole byte string for the rfid tag. I am just learning about using serial with the arduino so not much in the program made sense to me and the programs didn't say how they worked. Thanks in advance!

URLs in newsletter for non-HTML readers

Hi, just thought you would like to know ... I receive the frequent Instructables newsletters.  However, I read mail in "mutt", a terminal-based text-only email program.  If I want to follow a link in a message, I cut-and-paste it from the terminal to a browser. The URLs in the Instructables newsletters are ludicrously long, which makes them a chore to cut-and-paste.  One I wanted to access today was 740 characters.  I don't know of any compelling reasons for a URL to be that long.  (I'm sure there are "reasons", I just suspect the same goals could be accomplished with URLs less than 100 characters long). I'm sure I'm in the extreme minority here, so I don't expect anyone to rush to fix this, but just thought you would like to know at least one newsletter recipient almost never follows the links it contains. Sorry if this was not the appropriate place to post this.  A quick scan of the site did not turn up a "feedback to Instructables" option. Thanks, Mark

New instructables-card style stat reader?

Today, I noticed that I now have an avatar that resembles the instructables cards that gmjhowe and jayefuu have been advertising.  I personally like this, as it has self-updating stats, unlike the printed cards. Keep up the good work. EDIT- noticed that members now have a bar below their avatars in comments announcing the number of ibles they have, and their stats show up when you hover over that bar.  Personally, I find this rather distracting and unnecessary.  Double edit- Can someone explain the color coding system that I've seen?  I have a red bar, while some other have blue or green bars.  Is this based on the number of instructables you have?

Giving Commands to a Figurine to be Read Digitally

I'm trying to incorporate a series of RFID tags and readers for a project concept I'm working on. I have next to no RFID knowledge and mainly work as a conception-est. The problem I'm having right now is having an RFID or something similar inside of a figurine respond to a command given from another RFID reader or chip. I've played with the idea of putting and RFID reader inside the figurine, but threw that out due to space constraints. While the size of the figurine is not set in stone, I'm estimating somewhere between 2"-5" and there are other components that need to fit inside.  Basically, the command that is given heals the HP etc. of the figurine when it is touched to the the figurine (The HP and other values are recorded digitally).  I'm sorry if I'm not very clear. I guess a good analogy would be the Kartoz if anyone has heard of that. But instead of the reader in the Main bunny, the reader is in the  tags. And each "Tag" has a different function.

Sony Reader, Kindle, anybody have one?

Hey everyone, Sometime this year, I was considering getting either a Sony Reader or an Amazon Kindle, the primary purpose of which for me would be to have something small and compact that could hold all of my datasheets so I could read them while on the go. I was wondering if anyone owned either a Reader or a Kindle and could tell me: 1) Your opinion of the device 2) Is there anywhere I can go where I could demo such a device? 3) What process do I have to go through to upload files to the device (example: suppose I have a datasheet saved as a pdf. How do I convert it to a format usable on the Kindle/Reader?) Any input would be appreciated, thanks!

ttl output (binary) barcode reader module

Hello there;  I am working my final year project on library management system which needs to include a barcode reader hardware. As i am told by my advisor i can't use a barcode reader whose out put is the final ASCII value rather i have to get a binary (0 & 1s)output from my hardware, then convert that value using arduino or my C# code to generate the final result of the barcode for the book.   So, what is a looking for is, a ccd camera based barcode reader module whose output is ttl (or binary) i.e before it is decoded.  Any idea where i can find such a device, please   Any comment is welcome.  10x for your time.

Laptop's fingerprint reader, is it possible to reuse it on desktop?

The dead laptop is a HP Pavillion dv3 4010sl, the sensor is a Validity VFS301 (cdk1071_r04_hf) as written on the sensor itself. if i remember correctly it was shown as a USB peripheral. maybe is simple and it need just some resoldering to a USB cable, the problem is that the flat cable connecting it to the motherboard has 6 pins/lines and my knowledge in electronics is quite limited... I've found online what seems like a motherboard schematics (pg.48) and the vendor's sensor's manual. Does Anyone knows if is possible, If yes how?

What would help move you from Reader to Maker?

Instructable authors love getting feedback from members.  We especially love it when someone builds the project we've made an Instructable for.  If you post a picture or a slideshow or a video... wow!  It makes us very very happy! So, as a sister question to the "I Made It" Challenge Month contest I'm asking: What would it take for you to make something and share a photo/video of it with the author?* As an author I've tried to offer what meager rewards I can, offering special patches and a place on the 'Ible's own wall of fame for people who build them.  Building on that, here are some of my ideas to kick off the discussion. Per Instructable Hall-Of-Fame.  Sort of a rogues gallery for each Instructable that would let writers reward awesome people who comment on their 'Ible. To be eligible you'd have to comment on the 'ible, and you'd have the option to decline being listed.  Special 'I Made This' patches for authors to give. Each time a author publishes an 'ible they would get the ability to send a custom patch made from the 'ible thumbnail.  The "I Made This" patch would show up in their own category on  your profile page. More Visible Rewards.  Connected to one or both of the above, if you do enough "I MAde It" tasks you could get a special medal/icon on your avatar to show you've made lots of stuff. (I know you didn't like the "pro" indicators, but maybe this will be different.  Not sure if this idea has come up before.) What else is stopping you?  Is the process of posting an image or video too hard or confusing?  Are you intimidated to try to make something and share it?  Or do you have other reasons? Do you have other ideas?  Do you like or hate these?  Comment here and hopefully the development team will see something they like. *In addition to a contest.
