This is the story of my pyANS script, a Raspberry Pi A+ based portrait ANSI Scroller and myself. To understand, I have this unreasonable addiction to ANSI art from back in the BBS days, the artists abilities to create with the character set available always intrigued me. I have long pondered how to put together a digital frame to display this art at home, more specifically a portrait digital frame. I'd love to build some static light boxes one of these days as seen over at http://ansi.notchill.com/, they also built a version of a digital scroller for an exhibition called. How I would have loved to have been able to attend that event. Having read through the article their version of the digital scroller is a bit beyond my current technical abilities so I continued considering other options. The answer lay in the availability of the small form factor ARM computers, in this case I had a Raspberry Pi A+ laying about It runs Linux and it runs Python ... this seemed like a good fit. What I used, it was cobbled together from the gear I had on hand, the list below gives you an overview of what is incorporated in this build. Nothing particularly out there although I'd love to get a 60" screen and run an ANSI wall. Guide was last updated 2016-02-15
# uncomment to force a console size. By default it will be display's size minus # overscan. framebuffer_width=640 framebuffer_height=1024 # rotate display 90 degrees display_rotate=1Edit /cmdline.txt Add logo.nologo to the command line to hide the console logo Add consoleblank=0 to the command line to stop the console turning black after a period of time

cd ~ git clone https://github.com/sairuk/pyANS.gitPlace your ANSI art packs in the libraries/ folder and reboot your Pi, you mileage may vary duplicating my settings exactly so there may be some tweaking involved to fit your chosen display perfectly.
The rear of the unit is relatively non-descript, Raspberry Pi hangs freely, I may fix it to the bracket when its mounted on the wall but otherwise it is fine as it is.
BTW, Throw me some skulls on Hackaday.io if you like this project
