Learning Python With Tron Radio

[5 Volt Junkie] has built his share of Arduino projects, but never anything with Python, and certainly never anything with a GUI. After listening to Internet radio one day, a new idea for a project was born: a Raspberry Pi with a small touchscreen display for a UI and displaying soma.fm tracks. It’s finally finished, and it’s a great introduction to Python, Pygame, and driving tiny little displays with the Pi.

Playing soma.fm streams was handled by mpd and mpc, while the task of driving a 2.8″ TFT LCD was handled by the fbtft Linux framebuffer driver. This left [5 Volt Junkie] with the task of creating a GUI, some buttons, and working out how to play a few streams. This meant drawing some buttons in Inkscape, but these were admittedly terrible, so [5 Volt Junkie] gave up and turned on the TV. Tron Legacy was playing, giving him the inspiration to complete his Tron-themed music player.

The result of [5 Volt Junkie]’s work is a few hundred lines of Python with Pygame and a few multicolor skins all wrapped up in a Tron theme. It looks great, it works great, and it’s a great introduction to Python and Pygame.

Thinner client using STM32 and NTSC monitor

[David Cranor], along with [Max Lobovsky’s] help, managed to build a thin client that uses an NTSC television as a monitor for only $6. This is his first foray into the world of ARM architecture and he has vowed to never use an AVR again. The powerful little chip uses timers to manage sync and DMA to transfer the full 480×240 frame buffer to the screen. Overclocked at 80 MHz there’s a lot of potential in this little board and he plans to take on the challenge of a full-color display for his next trick.
