Notes & Errata
Pool Lap Counter, March 2017: on the circuit diagram two 1kW resistors are
SC
missing between the bases of Q4 & 6 and the collectors of Q3 & 5 respectively.
Both are shown correctly on the PCB and are listed in the parts list.
Stationmaster, March 2017: on page 36, Fig.2, LED5 is mistakenly listed twice,
LED4 is the one closest to CON3. Also, CON2 is shown with all its connections
shorted on Fig.2, the PCB has the correct connections made.
Squash and Ping-Pong, Circuit Notebook, February 2017: Trimpot VR1 should
be connected directly to the +5V rail rather than junction of the reset switch and
100nF capacitor. If this is not done, the speed of the ball cannot be properly adjusted.
Voltage/Current Reference with Touchscreen, October & December 2016: in the
overlay diagram (Fig.3) on page 66 of the December 2016 issue, a 10nF capacitor
is shown below and to the right of IC3 (near the centre at the top of the board). This
should be 100nF instead, to reduce noise in the output. It is shown correctly in the
circuit diagram in the October issue, between pins 1 and 2 of IC5a, and listed correctly in the parts list. The PCB correctly shows this as 100nF on the silkscreen.
SemTest, February, March & May 2012: in the parts list on page 86 in May 2012,
SCR1 is incorrectly listed as a TYN812 semiconductor, where it should be a TYN816.

WARNING!
SILICON CHIP magazine regularly describes projects which employ a mains power supply or produce high voltage. All such
projects should be considered dangerous or even lethal if not used safely.
Readers are warned that high voltage wiring should be carried out according to the instructions in the articles. When working
on these projects use extreme care to ensure that you do not accidentally come into contact with mains AC voltages or high
voltage DC. If you are not confident about working with projects employing mains voltages or other high voltages, you are
advised not to attempt work on them. Silicon Chip Publications Pty Ltd disclaims any liability for damages should anyone be
killed or injured while working on a project or circuit described in any issue of SILICON CHIP magazine.
Devices or circuits described in SILICON CHIP may be covered by patents. SILICON CHIP disclaims any liability for the
infringement of such patents by the manufacturing or selling of any such equipment. SILICON CHIP also disclaims any liability
for projects which are used in such a way as to infringe relevant government regulations and by-laws.
