High-Temperature Thermometer/Thermostat
11 May 2012
Need to measure or control temperature over a very wide range? Now you can do it with this compact unit which hooks up to a K-type thermocouple. It drives a relay which can be used to precisely control the temperature in ovens, kilns, autoclaves, solder baths or at the cold end of the spectrum, fridges and freezers. It is based on an Analog Devices AD8495 precision instrumentation amplifier with thermocouple cold junction compensation.

Getting The Most From ADSL
09 May 2012
It's a fair bet that most readers of SILICON CHIP enjoy their daily fix of internet access by courtesy of ADSL. While some readers are luxuriating with optical fibre - and an unhappy minority are still using dial-up - most of us owe our ongoing communication to the distinctly freakish technology of ADSL. But what exactly is ADSL and what came before it? How does it work and why is it often called a "freak" technology? Are your internet speeds painfully slow? Can anything be done to speed them up? Do you curse your ISP? Read on!

PIC/AVR Programming Adaptor Board; Pt. 1
05 May 2012
Do you frequently program microcontrollers with a serial programmer? Want to streamline the process so you can quickly do virtually any micro? Well now you can! Our new Programming Adaptor Board, in combination with an In-Circuit Serial Programmer (ICSP), allows you to program most 8-bit & 16-bit PIC microcontrollers as well as 8-bit Atmel AVRs. It has a 40-pin ZIF socket and is configured with just a few DIP switches.

Q & A On The Maximite Microcomputer
17 April 2012
Thousands
of Maximites
have now been built
and have worked perfectly
the first time. The design
of the Maximite has proved
to be remarkably robust, so
if you have a problem with one
you have just built, it most probably will be
something specific to your Maximite and not
a fatal design fault or software issue. However, there are some
common problems that constructors do experience so we asked
the designer, Geoff Graham to come up with the six most common....

SoftStarter: Taming The Surge Current Menace!
13 April 2012
Are you alarmed by the juicy "splattt" from your mains power point when you plug in something like a large plasma TV set? Do you some-times burn out light and power point switches because of the surge currents at switch-on? Or perhaps you occasionally trip circuit breakers because of appliance switch-on surge currents. This is a very common problem but there is a simple cure: our SoftStarter. It tames those nasty surge currents while having no effect on appliance performance.
