Power miser mode
The processor used on your saber sound board is state of the art and runs internally at
over 100MHz. This amount of pure compute power can generate heat inside your hilt. In
order to mitigate this, the processor is put into a power miser mode whenever the saber is
inactive.
When the saber turns on and off, it is waking the processor up and putting it back to
sleep. Because of this, your battery life will be extended 10x compared to if the
processor was continually running.
The upshot to this method is that your sound board is only generating heat when it is
active and playing out sounds. Once the saber plays out the powerdown sound, it goes
back to sleep, thus saving battery life and reducing heat soak inside your hilt.
One drawback to this method is that you might hear a slight pop noise on the beginning
of the ignition sound and at the end of the retraction sound. This is normal for this power
miser mode. If you wish to rid of this pop, we can reprogram your board to continuous
run – but this comes with a high power penalty.
Speaker selection
You can use any type speaker with the sound board, we recommend a 4-8 ohm speaker
capable of handling at least 1W for best results. Smaller speakers may crackle if they
receive too much power. Proper speaker selection also involves mounting it in your hilt –
you want the hilt cavity to create a sound chamber which will increase the speaker’s
volume.
TIP: It is typically best to install the speaker in the lower part of the hilt and use the
entire hilt tube as a resonating cavity.
