Crazy Cricket or Freaky Frog

07 June 2012

Love the sound of crickets and frogs (and who doesn't)? Maybe you will revise your judgement after exposure to Crazy or Freaky - the (very) pesky cricket and equally annoying grenouille.

Ultra-LD Mk.3 135W/Channel Stereo Amplifier, Pt.3

25 May 2012

Finally, we present the specifications for the new Ultra-LD Mk.3 Amplifier along with a couple of minor tweaks to the design to maximise its performance.

SemTest: A Discrete Semiconductor Test Set; Pt.3

20 May 2012

Now that we have looked at the full circuit of our new Discrete Semiconductor Test Set, it's time to describe its construction and the setting-up procedure. We also describe how to fit a crowbar circuit to quickly discharge the HT after making high-voltage measurements.

1.5kW Induction Motor Speed Controller, Pt.2

16 May 2012

Last month, we described the features of the 1.5kW Induction Motor Speed Controller and explained in detail how it works. This month we describe its construction and testing and give some guidelines for use.

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.

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.
