Lorannoyatron
This is a mashup of Lora and an Annoyatron, producing a long rang annoyatron. The Lorannoyatron has two parts; a base station with an Arduino Pro Mini, DFPlayer, and SX1278 Lora module, and a remote control with a custom ATmega328PB board with another SX1278 Lora module. The remote control is used to select a sound to play and remotely trigger it on the base station.

Base Station
Base Station   Base Station
The base station is the speaker. It needs a pretty good 5V power supply (at least 1A) or the DFPlayer will swamp it at high volume. The base also has a useless 8 digit 7 segment display that shows random patterns. The TEST button plays the recordings; the STOP button stops anything that's playing now.

Remote Control
The remote control is battery powered. A knob selects a MP3 recording to play. Another knob sets the volume. The SEND button plays the selection on the base station.
