Hello Everyone,I have designed a prototype to charge your mobile phone for particular amount of time by inserting a coin. It can be used in the places like railway stations, bus terminals, shopping malls and tourist spots. Our system recognizes the valid coin through a coin acceptor and sends the signal to a micro-controller. Upon recognizing a valid coin ,a digital pulse is triggered and a reverse countdown of timer will be initiated. It displays the remaining time for charging the mobile. Even if a coin is inserted in the middle it continuous to charge with added time. I have designed it in such a way that it adds one minute for one rupee coin and five minutes for five rupees coin respectively.
I believe this product can make a commercial success if it is taken to the next level and I am here for all your support to take my prototype to a decent product.
Easy to design.
It can be operated by anone.
No complicated circuits.
Possible to provide 24*7 support.
It can be damaged (A camera can be attached for security purpose in such cases)
HERE IS MY PROTOTYPE,
That is all the work I have done till date on the vending machine. You can sum up your queries & suggestions at the comment section.
I am waiting!!
How To Receive Resume Credit
You can help me with,
Finding solutions to reduce cost.
Help with PCB design
Find me a best controller for this product ( low cost, reliable and efficient)
Attracting casing solutions
Teammates & Contributors I’m Looking For
Taking the product to a commercial success
Good and attractive low cost casing (Also, a 3D design for the casing)
Where I Need the Most Help
To find the casing for this product . Any help would be gladly appreciated.
Why Sponsor This Project?
My intention is to give out a low cost product.
Every commercially successful product was once an idea and a prototype. Contributors will be giving life to this product which would otherwise vanish in the race of a demanding life.
Why I’m Passionate About This Project
I have made a lot of prototypes in the last three years and I have come to find this as an interesting one.
If I could successfully accomplish this task, I am looking forward to add additional WI-FI option with this vending machine (Like getting a WI-FI for five minutes in case of urgency). Thanks for reading.
Following several discussions @Josh Pinkley redesigned the circuit as follows:
He also helped me to accomplish the PCB design and i am ready to print!!
To take the prototype to an active product i have designed 3d models as follows:
These are the updates till now and we are ready to fabricate now …I will further update on this project once if i take the print of PCB design…
*Need more contributors and active participants.
*Students who wish to learn.
*Of course FUNDING for this project.
I also personally thank @Suria Sarath and @Harsha for their efforts as well…
