Next Month in Silicon Chip Using a DDS Module for AM Radio IF Alignment Advertising Index Altronics.............................. INSERT In this article, we present updated software and slight tweaks to the hardware of the Micromite BackPack Touchsreen DDS Signal Generator described in the April issue. These changes make it a cinch to align the IF stage of a transistor or valve-based superheretodyne AM radio. Dave Thompson......................... 111 Rohde & Schwarz RTB2004 DSO Review Emona Instruments.................... IBC We take a look at this latest offering from R&S which combines a 10-bit ADC and 10.1-inch capacitive touchscreen along with either two or four channels in a compact bench-top unit. New Developments in LED Lighting We take a look how LEDs are now rapidly supplanting all other forms of domestic lighting whether it is incandescent, fluorescent (strip lighting and CFL) or 230VAC and 12V halogen. But LEDs are often not dimmable or cannot be dimmed with conventional dimmers. We tell you what you need to know. Emergency Brake Warning for your Car Brake lights are important in warning people behind you when you're stopping but the problem is that they light up whether you're barely pressing the pedal or are pressing as hard as you can. This project will add a feature of many premium vehicles to just about any car: rapid flashing of the hazard lights under heavy braking, to warn any tailgater that you will soon be stationary! Note: these features are prepared or are in preparation for publication and barring unforeseen circumstances, will be in the next issue. The July 2017 issue is due on sale in newsagents by Thursday June 29th. Expect postal delivery of subscription copies in Australia between June 29th and July 14th.

They should instead be M3 x 6mm (M3 x 8mm may also work). Also omitted from the parts list is the jumper shunt and 2-pin male header needed for JP1, and in Fig.1 JP1 is mistakenly labelled as LK1; the PCB overlay is correct. The kit we supply comes with the correct parts. SC Online Shop............. 99,104-105 ATmega-based Metal Detector with stepped frequency indication, Circuit Notebook, March 2017: the circuit diagram published is missing two 10kW resistors, one of which is connected between the anode of D1 and pin 27 of IC1 and the other goes between pin 27 and ground. This allows IC1 to monitor the battery voltage and display it on the LCD.

SILICON CHIP magazine regularly describes projects which employ a mains power supply or produce high voltage. All such projects should be considered dangerous or even lethal if not used safely. Readers are warned that high voltage wiring should be carried out according to the instructions in the articles. When working on these projects use extreme care to ensure that you do not accidentally come into contact with mains AC voltages or high voltage DC. If you are not confident about working with projects employing mains voltages or other high voltages, you are advised not to attempt work on them.
