The Wolfson Audio Card for Raspberry Pi

via Elektor.uk: News

At Embedded World 2014 recently Element14 were showcasing the Wolfson audio board for use with the Raspberry Pi. It addresses many of the shortcomings in the standard RPi’s audio capabilities and makes it usable as a digital audio recorder/player, VoIP telephone, recording device and works in conjunction with the RPi camera module.   It plugs into the Raspberry Pi’s board and makes use of the P5 pads (2 x 4-way) which are only featured from revision 2 upwards of the RPi board. Connectors...

Plotclock Writes the Time!

via Elektor.uk: News

Plotclock is something of a novelty, guaranteed to put a smile on your face. It uses an Arduino uno to control three R/C servos which guide a white board marker across a surface to write the time of day. When a new time is available the marker picks up the white board eraser and wipes the surface clean before writing the new time.  Two of the servos control the X-Y pen movement via a linkage while the third servo lifts the pen at the end of each stroke.   Details of this open-source...
