Digital Guitar Amplifier/Effects ProcessorThe Teensy 3.2 MCU ModuleBy Brian MillierIn this series, Brian presents an innovative guitar amplifier/effects design, which features a Teensy 3.2 microcontroller module, an audio adapter module, a simple preamp/buffer, and a 20-W Class AB power amplifier. This month he introduces the Teensy 3.2 MCU module and the necessary software.
Declarative Finite State MachinesBy Chris CantrellState machines are neatly defined in a declarative data structure-a picture in the code. Chris designed an example tic-tac-toe state machine for an 8 Ã 8 LED display and a back-lit pushbutton. He implemented the state machine using two different programming languages on two very different platforms. Scap BackA Super Capacitor Power Backup for the Raspberry PiBy Don McLaneWhen designing Raspberry Pi-based IoT systems, you must account for the possibility of power outages, which can destroy your device's entire file system. Don presents a super capacitor power backup that should calm your power failure paranoia. |
