El Cheapo Modules, part 9: GPS modules
We describe two common GPS modules, their features and how to interface them
to an Arduino or Micromite.
Using a DDS Module for AM Radio IF Alignment
In this article, we present updated software and slight tweaks to the
hardware of the Micromite BackPack Touchscreen DDS Signal Generator
described in the April issue. These changes make it a cinch to align the IF stage
of a transistor or valve-based superheterodyne AM radio.
LTspice - simulating and testing circuits, part 3
We build on this month’s article by showing how to design a subcircuit to simulate
an NTC thermistor, in order to complete our simulation of the SoftStarter. This
involves some advanced SPICE modelling techniques and you will be introduced
to more of the software’s features along the way.

The Death of Cassini
The Cassini-Huygens probe was launched from Earth on October 15th, 1997 and
entered orbit around Saturn on July 1st, 2004. Since then, it has been studying
Saturn, its rings and its moons. It will be deliberately crashed into Saturn on September 15th this year. We look at the great scientific benefits of the Cassini mission over the past 20 years.
Fully Adjustable Stereo 2/3-way Active Crossover
This new active crossover design is suitable for use in hifi systems and unlike our
last such design, it’s easy to tweak the crossover frequencies and gain/attenuation for each frequency band. This allows very accurate tweaking of loudspeaker
performance to suit the characteristics of the individual drivers used.

Notes & Errata
Arduino-based Digital Inductance/Capacitance Meter, June 2017: the soft-SC
ware as provided assumes an I2C LCD address of 0x27 which is for displays
with a PCF8574T IC. If your display has a PCF8574AT IC, you will need to
change the address near the top of the sketch from 0x27 to 0x3F before compiling and uploading it. Note also that if printing the front panel artwork PDF,
you need to set up your printer to print “actual size” (rather than “shrink to fit”,
etc) so that it comes out the right size.

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.
