NextBus transit clock for Raspberry Pi
Should I stay or should I go now?
by Phillip Burgess
For transit-bound people, NextBus — a free internet service providing arrival data for over 135 transit agencies — is a tremendous convenience. Knowing when a bus is due means less standing out in the rain…one can use that time inside to get a little extra work done, or finish that cup of coffee. Using the Raspberry Pi computer, we’ll create a dedicated NextBus “appliance” that informs at a glance.

The Pixif
A simple, efficient SPI front-end for NeoPixels
by David Littell
A PIC is used as a SPI Master to create a simple interface to up to 21845 NeoPixels. After being configured with the number of attached NeoPixels the Pixif continuously retrieves the RGB values via SPI and generates the NeoPixel GRB bitstream. The update rate may be throttled via a synchronization input. This approach frees the host processor to concentrate on its algorithms especially when its SPI Slave has DMA support.
