I've put the sound generating parts of the upcoming – as yet nameless – raspberry model up on the website for you to download and have a go.

It makes quite a satifying raspberry noise as you'll be able to see now that I've fixed the video below.

Subscriber's can download the print it out and have a go. the instructions are pretty basic so let me know if you have any problems. I'd also be interested to hear if you are successful!

Have fun!
