Diversionary device with electronic trigger and directed high efficiency output

A single-use diversionary device, comprising:

• a semi hollow barrel having a closed first end forming a pressure resisting bulkhead and a second open end that receives one or more powder cartridge assemblies;
• an upper cap connected to the hollow barrel at the first closed end;
• and
• an electronic timing circuit protected by the cap and configured to generate a pre-defined timing delay, activate an electric primer and subsequently eject energetic powder materials from the device thereby creating an explosion in free space;
• the electronic timing circuit includes a timing section, a power source and a low power relay configured to capitalize on the fast blow nature of electric primers;
• an electronic circuit that can be adapted for use with conventional diversionary devices due to its small size, low cost and minimal number of components.
