This month’s highlights
Micromite-based Super Clock
This highly versatile menu-driven electronic clock can display the time three ways – a traditional analogue clock with seconds hand, a 12 hour digital clock or a 24 hour digital clock. The Micromite-powered timepiece has no moving parts and uses a colour touch-screen LCD display. Also it can be set according to one of 20 time zones, having an optional GPS module for better accuracy.
You can choose a number of different time zones to keep track of the time overseas, scrolling to them via the touchscreen. Mains powered from a USB-type power pack. If you’re looking for a compact and stylish digital clock that’s a little different, this is the one!
Brownout Protection for Induction Motors
This low-cost design protects domestic induction motors against brownouts – when the electricity supply dips and the motor cannot start or run properly, risking burning out the windings.
Induction motors are commonly found around the home in fridges, freezers, washing machines, air conditioners, pool pumps – the list goes on. Our protection unit cuts out the mains voltage supply if it dips below a certain level, and only reconnects it again once it rises back to normal operating voltages. Anti-nuisance tripping is incorporated. Output relay rated for 2,300 watts.
100dB Stereo LED Audio Level/ VU Meter
This spectacular Stereo VU Meter will give your stereo system some LED bling! It uses 80 high-brightness SMD LEDs to produce a highly colourful dual bargraph display that simultaneously shows the average audio signal level plus peak level. And it can display ranges up to 100dB. Assembly and setting up details are provided in this month’s issue.
