Vintage Radio Capacitor Leakage Meter With LCD Readout
Ginormous 7-Segment LED Panel Meter Display Review: Hakko's FX-888 SMD-Safe Soldering Station

19 Dec, 2009

Vintage Radio

Mainly because of their size, radiograms and radiogram/TV combination units are usually ignored by vintage radio enthusiasts. However, a lot of equipment was produced and at least one collector, Peter Henstridge of Adelaide, SA, has restored some items to as new condition.

Capacitor Leakage Meter With LCD Readout

This instrument can perform a leakage current test on almost any type of capacitor in current use, including ceramic, mica, monolithic, metallised polyester or paper, polystyrene, solid tantalum and aluminium electrolytics. There are seven different standard test voltages from 10V to 100V, so most capacitors can be checked at or close to their rated voltage. Leakage currents can also be measured, from almost 10mA down to less than 100nA.

Review: Hakko's FX-888 SMD-Safe Soldering Station

For anyone involved in assembly line or service soldering, the Hakko brand needs no introduction. Their latest offering, the Hakko FX-888 Soldering Station features a number of upgrades and improvements over previous models and should find a ready market in the assembly industry, service personnel and technicians and advanced hobbyist users.

Voltage Interceptor For Cars With ECUs

At one time, the sensors in cars with engine management were regarded as untouchable. But now you can change the signal response of many of the sensors to improve your car's driveability, throttle response, handling and so on. This voltage interceptor allows you modify and program the response of any voltage sensor in your car, without prejudicing reliability or affecting the ECU in any way. Use it for restoring correct air/fuel ratios after engine modifications, preventing turbo boost cuts or altering sensor signals for improved driveability.

One-Of-Nine Switch Position Indicator

Originally conceived as a track-in-use indicator for model railway layouts, this one-of-nine indicator can used with any selector switch with up to nine positions. It can be used with a bank of reed switches, as might be used on a locomotive turntable or traverser on a model railway layout or with any switch with up to nine positions. Then we realised it had many other uses . . .

WIB: Web Server In A Box, Part 1

We're very excited about this project. It will let you house your own website with possibly hundreds or even thousands of pages, all in a little box connected to the internet via your modem/router. You don't need a computer to operate and house a website - this little box does it for you and it can be accessed from anywhere around the world, at any time, even from a mobile phone which has a web browser. In fact, it is a complete web server in a box - so we've called it WIB (Web server In a Box).

GPS Synchronisation For Clocks With Sweep Hands

The GPS Synchronised Clock described in the March 2009 issue only worked with crystal clocks that ticked once a second. The more upmarket clocks have silent sweep hands, which are much more acceptable in a quiet lounge room situation. Now, with just a few simple modifications, you can upgrade to one of these.

In July 2009 we presented an improved version of the Battery Zapper & Desulphator. Here we present the companion Battery Condition Checker. It gives more stable readings for all three main battery voltages (6V, 12V & 24V) than our earlier model, as well as giving a choice of test current pulse levels to suit batteries of different capacities. As a result, it?s now also suitable for testing sealed lead acid (SLA) batteries.
