For my third and most likely final instrument of the project, I've been building a xylophone using piezo transducers for trigger detection. You may notice some plastic bongos in the back of this picture - I've been attempting to get Nintendo's 'DK bongos' to behave with an arduino but I've not had much luck yet.
The main circuit is pretty much wired up now - each of the 12 keys on the xylophone has a piezo transducer wired to an analog pin on an arduino mega. This allows for you to trigger notes of varying volume.
I also plan to use an ultrasonic sensor to alter the sound of the notes. I've tested this out on a breadboard earlier in this project as can be seen in this video:
It's worth mentioning that the 'bass' instrument is now complete as well as the pianocade I'll film a video soon.
My friend Scott has just started work on his project in the lab with me, a pneumatically driven targeting sweet launcher! Check out his blog here: The Sweet Launcher He's been a great help with stuff on my project and he's an absolute boss at electronics so I'm sure he's going to be doing some really impressive stuff. We're both working as part of the Blake Bursary Project - where we work on the project of our choice as a demo for open days and workshops to give an insight into Electrical and Electronic engineering and the cool things we can make with it.
