500W Monoblock Class-D Amplifier by Phil Prosser. If you need a serious amount of audio power, are on a budget, and are not after ‘high fidelity’, this is for you! It uses two prebuilt modules and not much else, mounted in a compact metal chassis, to deliver heaps of audio power all day long.
TQFP Programming Adaptors by Nicholas Vinen. Our new Programming Adaptor, described last month, can program chips in DIP and many SMD packages. But what about those in SOT-23-6 or QFP? We show how to program such devices out-of-circuit with several reconfigurable programming jigs.
2m VHF FM Test Signal Generator by Andrew Woodfield. This Test Oscillator uses an AD9834 DDS chip in a somewhat unusual way, producing signals in the 2m band (144-148MHz), well above its 80MHz oscillator frequency. It can produce a CW signal and optionally add frequency modulation.
