It’s also very easy to use thanks to its touchscreen interface – by Nicholas Vinen 70 New “Facett” hearing aids from BlameySaunders They look quite different from previous models – not just because of their “facetted” design. These use rechargeable battery modules which snap into place using tiny, powerful magnets. But are they any good?

– by Ross Tester 76 El Cheapo Modules 15: ESP8266-based WiFi module The very popular ESP-01 WiFi transceiver module, based on the ESP2866 chip, is designed to allow almost any microcontroller to connect to a WiFi network. Download efs img i9300 pit. And best of all: as well as being versatile, they’re really cheap – by Jim Rowe Constructional Projects 14 230VAC Thermopile-based Heater Controller Here comes winter! But many radiators don’t have any form of heat control – they’re either flat out or off – not very satisfactory, as you either cook or freeze! This controller has two versions – dial up the temperature you want or vary the heat output over a wide range – by John Clarke New “FACETT” hearing aids look very different – and also use rechargeable magnetic battery modules – Page 70 Low cost ESP8266-based WiFi module allows you to interface almost any micro to a WiFi network! – Page 76 26 Low cost, Arduino-based 3-Axis Seismograph Following on from last month’s Earthquake Warning Alarm, we add some extra hardware and software.. And voila: a true Seismograph, capable of detecting and recording waves in three directions. We even show you how to record and analyse them – by Tim Blythman and Nicholas Vinen 58 The Clayton’s “GPS” time signal generator You don’t need a GPS receiver to get accurate time signals – you can get them with WiFi.

So accurate you won’t tell the difference and you can use them as a true time reference in critical applications – or just have a time signal that’s as accurate as the “pips” on the radio! – by Tim Blythman Your Favourite Columns You can now give your 230VAC convection or bar electric radiator dial-up temperature control or vary the heat output – Page 14.
