From their website:

It’s LOUD. You don’t need to be very close to it in order to hear it. You can cover more ground in less time searching for your aircraft.

Short review.

No! It’s not loud. It’s quieter than a PC beeper. Quieter than your charger beeper. The name “Screamy” is VERY misleading.

Confused how to make your BMP correct sized when converting it with import-bmp?

First of all:
– Make your image 2 colored BMP, great tool for Windows, Linux and OS X is the old classic XnView – For colored images I suggest dithering the image to 2 colored image
– Make your graphics as library package (in Eagle), trust me, it’s worth it (you can make changes easily and don’t mess up your board since the graphic is a package)
– Use layer 25 (tNames) for your graphics. When you have added the package to your board, you can change it’s side by mirroring it.

Then the secret formula:

Scale factor for pixel = wanted graphic size / image size in pixels

For example if you want 204 pixel wide image to be 10mm, you enter 0.0490196078 as the scale. (10 / 204 = 0,0490196078).
