Pi printer automatic tag feed controller

Project short description: Pi control's the flow tags that have to be printed. Project: develop time 2 weeks Software development PHASE 1: Get the electronics working Electronics -Pi face I/O controller -Temperature sensor -Touchscreen display -WiFi -Stepper controller -Rf-id reader -Light sensor -char-display -Epson ticket printer Python program: -basic hardware evaluation test -sock connection -mysql client -log tot txt file Pi Operating system Debian stripper and rebuild Personal start-up logo and icons PHASE 2: Get the printing machine working -Pi starts up -log's on and reports -collect assignment -check supply limit -check free collector -check right magazine is placed -Start printing (loop) -Block last transport -close assignment -print report -move collector next PHASE 3: The extras -vision character recognition -vision empty collector check -Datamax / Zebra bar-code printing PHASE 4: Finishing touch -Debug -Test -Correct -Expand I would need a coder to make software that runs on Raspberry Pi and to read data from the GPIO connector and other electronics part. Data needs to be stored in a database or text files that I will then transfer to a main server. EXPERIENCE with such type of programming is a MUST ! I do not have to stay and explain the coder how he is going to read the data from the GPIO connector. More details can be given when we choose the coder. Experience is a MUST ! I need to see example of work before I accept your bid. Contact messages like : Let's do it ! or "Let me make this for you" or anything like this will be deleted and ignored. Bids OVER the budget will be ignored. Coder preferred from Europe because of time-zones There will be no milestones before I see some work examples and before I can really see you can do this project. It's possible to use an third party. But that will be you're responsibility If you can convince me I'm willing to change program languish. Code must be documented. What can you aspect from me: -long time relationship minimal 3 years -more assignments -detailed flowcharts -needed hardware sent to you. -All project with fixed prices do not work on hour bases
