NOTES & ERRATA FOR PROJECTS PUBLISHED IN
SILICON CHIP (2010)

PC Boards for most Silicon Chip projects can be obtained from RCS Design, Sydney. Phone (02) 9738 0330 or visit www.rcsradio.com.au

Balanced Output Board For The Stereo DAC, January 2010: Pins 1 & 2 of the XLR sockets are shown transposed on the circuit diagram (Fig.1, page 43). The PC board and the parts layout diagram (Fig.2, page 44) are correct.

Note also that phantom power should not be applied to the XLR sockets of the Balanced Output Board (ie, phantom power should be switched off). Alternatively, cut the tracks between the 100 ohms resistors and the XLR sockets and install 10uF bipolar (BP) electrolytic capacitors across the gaps (ie, in series with the pin 2 & pin 3 outputs). (02/10)

PICAXE-Controlled Watering System, Circuit Notebook, February 2010: The suppression capacitor across the motor should be increased from 10nF to 220nF. (03/10)
