I often get asked about offering sound functionality in my prop kits that I sell. As demonstrated by my energy sword design I had a solution for sound, but it was not a solution that I could extend to my cheaper kits. Sound is hard, not just hard but expensive. Till now.
Introducing the 300 second USB recording module from <a href=”http://www.electronics123.com/300-second-usb-recording-module.html”>electronics123.com</a>. I have fully inregrated their sound module into the Backlit Ammo Counter offered in my store via an adapter circuit. The sound module can also be used stand alone, but you do not need me for that, go buy one from Electronics123! They are good folks.
The need for the Adapter Circuit
The sound quality offered by this sound module hits a sweet spot in cost to performance. In addition, the level of programmability at this price level is unmatched. The only function that cannot be programmed is to switch between two sounds based on a second input. I want to hear the firing sounds only when ammo is available, and the dry fire sounds only when ammo is not available. This is where the adapter circuit comes in. The backlit ammo counter already reports via the bottom LED if ammo is available or not. The adapter circuit takes the signal from that LED and the FIRE switch and performs some logic to decide which sound to play.
Is that simple, now the sound module gives sound effects exactly as expected for a fully automated weapon. Options for semi-automatic are in progress.
Secondary Announcement
New configuration options for the Ammo Counter in the store! Custom rates of fire. Prior to now all Fully-Automatic Ammo Counters have had the same fire rate of 5000 rounds per minute. Which is crazy fast for the most popular selection, the Halo AR having a fire rate of 600rpm.
