There should be further discussion about how far and wide the designs that Havlena has made have spread, as a number of other DIY instruments seen online seem to derive a large amount of the ingenuity from these original designs (without ever referencing Dennis Havlena). \\
There is an amazing amount of respect I have to give to the aspect that all of these meticulously made designs have been given out for free on Havlena's website. I think there should be a great deal more written about the generosity that is seen in DIY instrument groups that makes communities like this possible. \\
