Is an SD Card needed? Hold that thought and don't rush out to buy one just yet. I'm experimenting with a possible way to use the extra space on the ESP32 internal storage (we'd get about 8MB) instead. Since the standby images are so small and set lists are next to nothing, it could support...

On the back of the Waveshare screen is a little microSD card slot. This is why I built in support for connecting the whole thing as a USB Drive because disassembling every time you want to modify the contents of the SD card would be a HUGE pain.

Version 3.0.0 New Features SD Card Support - SEE IMPORTANT NOTE IN POST #10 BELOW Insert a microSD card (max size 32GB) formatted with FAT32 and experience more features! With Q-Tune unpowered, press and hold the footswitch when you connect it with a USB-C data cable to your computer and it...

Ooo, that'd be cool! That kind of thing wouldn't require an SD Card but it'd be a little limited by the FPS of this screen (the more things I put on the screen, the slower FPS it runs at). But, I could experiment! If you run in Buffered Bypass mode, some of the standby screens are interactive...

Next firmware update: Death Star edition. DOOM port pending. ;)

I spent the weekend experimenting with a couple of ideas that could be done if you add a microSD card into Q-Tune. With an SD Card (formatted as FAT32) inserted into Q-Tune, you hold down the footswitch button while you plug it into your computer with a USB-C data cable and then it mounts as a...

We've just released version 2.8.2 which has two new tuning UIs included and would love to get your feedback about them!

Version 2.8.2 Version 2.8.2 has all the features of 2.7.0 and more! Now available at https://www.q-tune.com/install New Features Orbital Tuner - An experimental tuner and far out experience where a comet travels in an orbit around your note. When flat, the orbit stretches and gets wider and...

I’ve been tinkering around with some experimental tuning styles and thought it’d be fun to brainstorm some together. Here’s a possible “Orbital” tuner: Because we’re dealing with an embedded system with limited processing power and storage space, that puts some constraints on what we can do...

The other thing to try would be to go to the Settings > Advanced > Factory Reset. Then, power off and back on again and then use the foot switch to switch back and forth a couple of times. Does it behave properly at that point?

@red any luck?

With LP2950 installed, what are the input and output voltages? The output side is the one closest to the 47uF electrolytic cap. The input is on the opposite side.

With MCP6002 removed, you still see only 1 VDC on Pin 8?

Sorry you’re experiencing any problems. First off, your build looks nice and clean and I don’t spot anything obvious. Just to double-check, the green cable you have plugged into the output jack. Is that correct? One other thing to try is going into Settings (tap the Q logo at the bottom right of...

Nice board! I’ve got code for a page turner for ESP32 but the hardware side of things needs some TLC. A couple years ago I had something cobbled together with various separate electronic components but it ultimately ended up biting the dust. I had a small lipo battery, a charge controller, a...

I definitely like the control of how it prints using a PDF. You have full control over where the page breaks are, page numbering, etc. I guess I might be an odd one out where I avoid printing paper at all costs. I have an iPad that follows me everywhere, including the workbench.

Thanks for the great insights! We’ll keep using the PDF. I also just added a link to access previous versions (the whole website is hosted on GitHub): https://www.q-tune.com/build/

Right now we're using a PDF for the build instructions but we're curious which format you all prefer if you could choose.

I’ve had similar thoughts but haven’t yet experimented with how to make that work yet. I think once summer activities and yard work stuff slow down I’ll have a bit more time to see what’s possible along these lines.

Yeah, there’s all sorts of possibilities with Daisy Seed. I’ve really only built the Flick for it so far. @keyth72 is the one who created the FunBox and all the cool planet series pedals. He’s done some really cool stuff!
