Practical Electronics January 23

Classic LED Metronomes:
These two Metronomes use only discrete components and simple logic chips, making them easy to understand and build. They are both great projects for a beginner.

Geekcreit's 35MHz-4.4GHz Singal Generator:
This self-contained module uses a wideband digital synthesiser chip, onboard microcontroller, OLED display and pushbuttons to set the desired frequency.

Remote Control Range Extender:
Convert an IR remote to use UHF and it will work at much longer ranges - even when something is between the remote and device.

Multi-Channel Speaker Protector:
If you're driving a lot of speakers you need a matching compact speaker protector to prevent driver destruction should something go wrong.

---
Series, Features and Columns:

Make it with Micromite;
Park 43: Connecting more than one display to a PicoMite

Circuit Surgery;
Part 5: Electronically controlled resistance

Max's Cool Beans;
Part 1: Arduino Bootcamp

Audio Out:
Part 2: Universal single op amp board (optimised for audio electronics)
