Hi,
I am working on a small college project in which I have to sort objects of different materials (glass, plastic, metal, and paper) into different bins in an automatic fashion.
I was thinking of using some sort of passive tagging system that is very cheap and doesn't need to store any data except that it can be categorized into 4 different types, because we are trying to sort 4 different types of materials. For example, we can associate each tag to one particular material type ( tag#1=glass, tag#2=plastic, tag#3=metal, and tag#4=paper) then if our object is made of the glass we stick tag#1 on it in which later can be detected by a reader and can be directed into glass bin.
I was thinking of using some sort of ultra cheap DIY radio tags in order to be used for tagging each object and then read those tags using a reader and then sort them into different bins.
I need a expert who can guide me through this sorting project who can give me advice and provide me with a feasible tagging solution that is flexible, ultra low cost and is commercially available since I am trying to build this system for my final presentation. I am planning to be able to buy the necessary equipment and eventually build it using an arduino.
Initially I was thinking of passive RFID tags but I am not sure if it is viable option or not, since my target cost for each tag is only few cents (I want each tag to cost less than 5 cents). Is it possible to make home-made RFID tag without any IC? I know there are chipless RFID tags but they are not commercially available for purchase right now, thus I cannot use them.
Or once somebody told me that I can make 4 different LC tank circuits that can oscillate at 4 different frequencies, therefore I can make a system in which oscillating frequency can be detected by some sort of reader. in this way I can print one type of LC tank (that correspond to certain frequency) on my object and detect which object is what. I am not sure if this is even possible since it was my first time hearing about LC circuits.
I am looking for an expert who has a low cost and bright idea. I might even end up outsourcing the implementation and building the prototype as well.
thanks
ACTUAL BIDDER! NOT A SUBCONTRACTOR!!!
Hello, i have a PhD in Mechatronics and ample experience with Arduino boards, as well as microcontrollers. I have most of the hardware needed to get this started and have worked on many projects before and i can provide proof of those projects.
Please contact me or view my profile for further reference.
Best regards
Hello.
I can provide consultations, example of circuit and simple program code for Arduino microprocessor.
My hourly rate is 10$/hour and it's very low rate for such job.
2-3 hours is enough for demonstration of materials and even for assembling of test device.
But I must to say than if you not familiar in electronics - you will need much more time for assembling and debug of device.
Feel free to write me in chat for discussion about detalis.
With best regards.

I have 5 years of software development. I have worked on different novel ideas. I can help you for this project as well. Pleases see my profile and reviews as well. Thanks :)
I am an Engineer and I like to hack using Arduino. I did my thesis in traffic light simmulation. I think I have a quick and dirty solution to your problem.
I won't use RFID tags. My "tags" would actually cost you $0, but the setup might be a bit more expensive. I think it is a innovative solution, but it depends on the setup and flow (position, speed) of the materials. Happy to explain my thinking with you.
PS if it works I would like to see a video of it. I love seeing solutions in action.
Hope to hear from you soon.
Hi,
I'm an Electronic Engineer form Sri Lanka.
I currently work on embedded system design from spec to product in collaboration with a USA based company and your requirement seems the same.
I'm sure that I can help you with this.
Let's discuss about the project
Hello,
the cheapest solution is to use small sized self-printed 2D-barcode (QR-code) paper labels or stickers. There is also a lot ready software and libraries to recognize it using any kind of cheap video camera, so the overall hardware cost will be very low.
