Silicon Chip July 2017

In this month's Silicon Chip Electronics Magazine, build the upgraded RapidBrake unit. This unit senses rapid deceleration and will flash your brake lights or hazard lights to give the driver behind a few extra seconds of warning to avoid a rear-end collision. The unit is based on the ADXL335 Accelerometer and complies with Australian design rules for flash rates and signalling. The RapidBrake also incorporates adjustable deceleration settings and LED indication. The project can be built easily with mostly through-hole components used with the accelerometer available as a plug-in module.

Also in this month's projects, build a Deluxe Touchscreen eFuse. This unit is basically a DC Circuit Breaker, providing very accurate cut-out times and also precise cut-off points for voltage and current. The unit features a touch screen display with real-time voltage and current readings. Finally this month, build an Arduino Music Player, with just the addition of the VS1053 MP3 Music Shield, together with a keypad and LCD display, you can have a complete playback unit, similiar to modern off the shelf playback units. All projects come complete with circuit diagram and electronic parts list.

In this month's main feature a look at Incat. Incat build a wide range of state-of-the-art high-speed catamarans for use as passenger ferries or navy patrol vessels. In this article a quick look at the production facility as well as some of the catamarans that have already been built. Also this month, how to use dimmers with the new LED lights now available for your home. Conventional dimmers are mainly designed for incandescant lamps and will not work well with the new LED lights, this article looks at the theory and how to select the correct dimmer. Plus all the regular columns, including the Circuit Notebook, Serviceman's Log and Vintage Radio are included, providing stacks of great reading.
