This is my first project published, so if i miss something and you cant follow, just write me and i try to improve the tutorial :)
First of all this is not my project, i just did use this project PolaPi (https://hackaday.io/project/7176-polapi) and modify it so it fits my needs.
And i want to write a complete documentation with all steps as the project is not an easy to follow tutorial.
The Camera has now a Battery Indicator
I did present the camera at the Maker Faire Vienna 2017 and was honored as "Maker of Merit"
New Case plan has been added
First version of the instructions is done, lets see when i will find the time to review it myself :)
if you have any questions just ask!
Thermal Printer configuration/tweak
if you bought the printer over Aliexpress, the seller will ask you which settings you want, then u dont need to do this step. If not read carefully!
Standard baud rate the printer comes with is 19200 (you could leave it like this and edit the config file to use 19200 as baud rate) but you get better results if you change it to 115200. You need a USB to 5v TTL serial converter for this stepchange the printer baud rate to 115200 and code page US
then you have to add a stepper pin which regulates the flow control. Please be very carefully doing the next steps scratch the layer as shown in the pictures.
TTL cable modification
cut off the green wire of the TTL Printer or just remove it, use a thin screw driver to unplug it (if you run the printer with 7,4V and attach the Tx to the GPIO of the Raspberry you can damage it, so as it is not needed we unplug/cut it, so there is no risk of destroying your raspberry)
