And here's a video of the actual hardware playing:

Hi All, A few years ago I finished off a project with a teensy 3.6 to visualize MIDI data with LED strips. I've finally gotten off my backside and documented it. Hopefully others will enjoy. The device can be used in two ways: * If the teensy is plugged into the PC it acts as a MIDI device...

OK, I've got it all working now. Turned out my original code was accidentally overwriting the header, which presumably prevented the AudioPlayMemory object from recognizing the array as legitimate. In case it's useful to anyone else, here's a quick (and inelegant) sketch which populates an...

Yep, that certainly looks more consistent, but you can see from my second screenshot that the two example files "guitar_a2_note" and "guitar_b3_note" still don't fit the pattern. (Although other 16-bit files with the same sample rate do). I'm keen to find out what the proper format for...

Hi All, I've got some questions about the behaviour of the AudioPlayMemory object, and how it expects the array containing the samples to be laid out. I've read the old documentation here: https://www.pjrc.com/teensy/td_libs_AudioPlayMemory.html as well as the AudioPlayMemory page in the...

Hi Phi, I never got around to it, sorry. I'd be interested to hear how it goes if you implement it. Cheers, Gavin

Hi Andre, Life got in the way and I haven't had a chance to try it, sorry. If you get it running please let me know! Cheers, Gavin

Aah, good point.

Very nice photo DukeBlue! Were you able to make any significant errors appear in the chip? You're reminded me of a quick experiment I did about a decade ago. At the time I was commissioning some large (from memory something like 100keV) industrial X-ray units, and we ended up having some free...

Hi All, The background to this is I’m investigating quick ways for me to get extra audio channels into the Teensy. (I’m in Sydney and our supply chain is not exactly prompt) While browsing around for stuff to improvise with, I noticed that my local electronics shop has a bunch of the Respeaker...

Awesome looking unit Cowlander! Hope your commissioning goes well. Out of curiosity, do you use EPICS for a control system, or is it all Labview? I did the installation of a synchrotron storage ring RF system a few years ago, you picture is bringing back memories...

Hi WMXZ, I am using microphones as the input. For this project I was hoping to keep the hardware simple and off the shelf (I’m mostly operating in a hot-glue everything together mode right now), but that’s certainly an option. OK, I think I’m understanding about the TDM idea. Here’s my...

Hi All, I’m working on a (about to be open source) project right now involving a teensy 3.6 as lock-in amplifier: https://en.wikipedia.org/wiki/Lock-in_amplifier At the moment I’ve got it working quite nicely with the Teensy 3.6 and audio shield, and I can see the detected response as a...
