Mini Pipistrelle LED colours

You could have just one colour of LED, to produce a Spectrogram type display, and this is what Phil used to suggest, all red.

However you can buy the bottom firing 1206 LEDs in: Red, Orange, Yellow, Green and Blue (more expensive). And while a single colour may look good, we feel that with options available you might was well:

  1. Have different colours for the peak frequencies of the two most common bats Common (40’s kHz) and Soprano Pipistrelle (50’s kHz)
  2. Likewise the Lesser (100’s kHz) and Greater Horseshoe (80’s kHz) peak frequencies may as well have different colours.
  3. Lastly the “big bats”, the noctule and serotine, which peak in 10’s or 20’s may as well have a separate colour.

So below are just some of the many thousands of possible LED combinations you could choose. However we find that when we have explained the above 3 ideas, over 95% of the people in our workshops choose to make one of the 5 colour rainbows. This is undoubtedly also because the rainbow LEDs just look awesome!

Note: Beware of bottom firing 1206 LEDs from other sources, they may not fit in the mini Pipistrelle boards. We have found that many have different sized larger lenses on then, and smaller contact pads, which mean that while cheap, and in lots of other colours (While, Pink, Purple .. etc), sadly they do not fit.
