It's time for the next Gadget Master competition, and we are taking inspiration from Joel Young's recent Weird & Wireless post - Does unplugging all your wall-warts really matter?The prize to be won this month is the Plug-In Power and Energy Monitor Meter.
Measuring voltage, amps, watts, volt-amps, frequency and power, this clever little unit lets you check just how much power your home appliances are using, or wasting. It is potentially a very good way to help keep electricity bills down.
The prize question
As always, we'll keep the format familiar and straightforward: correctly answer this question for a chance of winning the energy monitor.
Our recent In the (LED) light post featured eight LED-related posts. Which one has a picture of a circuit diagram?
Once you know the correct response, just email competition@electronicsweekly.com giving the title of the post.
The competition closes Friday 16 October. You can view the Terms and Conditions.
Good luck!
