Contents Vol.33, No.12 December 2020 SILICON CHIP www.siliconchip.com.au Features & Reviews 12 Automotive Electronics, Part 1 Cars have improved drastically over the last few decades. Much of this improvement is due to the expansion and integration of electronics such as the engine control unit, infotainment, cruise control etc – by Dr David Maddison 36 Making PCBs with a Laser Engraver or Cutter PCB prototypes are pretty cheap to order online, apart from postage, but it’s a long wait if you only want one or two boards. Using a laser cutter can be an inexpensive way to etch your own boards – by Andrew Woodfield 48 A Closer Look at the RCWL-0516 3GHz Motion Module Leading on from the short introduction we did on this module in February 2018, we take a more detailed look about the operation of this device and what modifications you can make to it – by Allan Linton-Smith Cars are constantly becoming more advanced and complex due to the inclusion of electronic systems. Let’s take a look at the various electronic systems that are used today – Page 12 76 El Cheapo Modules: Mini Digital Volt/Amp Panel Meters A surprising number of low-cost miniature panel meters have come onto the market lately. They display voltage and current (and sometimes more), with this article focusing on the DC variants – by Jim Rowe Constructional Projects 26 Power Supply for Battery-Powered Vintage Radios For most vintage radios, A & B batteries are extremely difficult to obtain. This power supply lets you use common Li-ion or LiPo cells to provide the A & B supplies for battery valve sets with HT in the range of 24-135V and LT of 1.22.5V – by Ken Kranz & Nicholas Vinen 44 Dual Battery Lifesaver This simple project helps protect rechargeable batteries from being drained if a device is left switched on. It works with devices that run from a single battery, or two separate batteries like our Supply above – by Nicholas Vinen This Power Supply makes it easy to modernise your battery-powered vintage radio sets. It uses Li-ion or LiPo cells and supplies a wide-range of high tension (HT) and low tension (LT) voltages – Page 26 68 Balanced Input Attenuator for the USB SuperCodec Pt2 Following on from the description of how the Input Attenuator add-on for our USB SuperCodec works, here’s how to assemble and test it – by Phil Prosser 90 Flexible Digital Lighting Controller – part three In the next part of the series, we’ll show you how to use RGB LEDs with the Lighting Controller and in conjunction with mains lighting – by Tim Blythman Your Favourite Columns 61 Serviceman’s Log A brush with disaster – by Dave Thompson Here’s a low-cost and relatively simple way to make your own PCBs using a laser engraver or cutter – Page 36 85 Circuit Notebook (1) Automatic tyre inflator/deflator (2) ‘Infinite’ impedance AC source (3) Controlling model railway points with a servo 100 Vintage Radio 1928 RCA Radiola 60 superhet – by Dennis Jackson Everything Else 2 Editorial Viewpoint 4 Mailbag – Your Feedback 98 Silicon Chip Online Shop siliconchip.com.au 106 Product Showcase 107 Ask Silicon Chip 111 Market Centre 112 Noteselectronics and Errata Australia’s magazine 112 Advertising Index Our new Dual Battery Lifesaver can be used to protect two separate batteries from being drained by wayward devices – Page 44 December 2020 1 www.facebook.com/siliconchipmagazine
