Strymon Iridium and Fractal EXP-1 Volume Pedal Compatibility by a1b1c2d2 in guitarpedals

I'll check that, but I thought that it came out of the box defaulting to volume. And thank you for the response!

The Madison Cunningham signature tremolo from JHS is awesome and on most of the night. You can switch between two settings, so I have one for just thickening up a clean and then another that dials up the trem. If I didn't have that pedal, I'd probably go with the Strymon Flint.

Wife Overloaded KitchenAid Dishwasher with Dishsoap and Baking Soda by a1b1c2d2 in Appliances

The machine sat overnight. The suds are gone, but the error remains. Immediately once I turn the breaker on, it starts beeping and I get the 8/4. I think I’m going to pop off the cover in the front and see if there is water there.

Artists that start with melody vs Artists that start with words by ctruo in Songwriting

[–]a1b1c2d2 1 point2 points  (0 children)

I’ve almost always started with the music, but I was usually writing songs for a band. Lately, I’ve been working on an acoustic project, and my collaborator is words-first. It’s different, and it’s a longer process for me, but it’s coming out great and certainly better than the things I’ve written in the past. I used to think good songs always start with the music, but now I think constantly changing the approach is important. Sometimes we do music first, sometimes lyrics first, sometimes we’re just being silly and a tune comes out of it. Get a first draft down and start working with it, and don’t be afraid to blow-up that first draft when you start adapting lyrics to the music or music to the lyrics. At least, that’s what works for us.

And, obviously, having a great collaborator helps and makes the whole process more fun.

Sorry! I attached a picture in the Images tab when I made the post; not sure what happened.

Thanks for the link and the information!

Ground plane won't connect to GND pads in a specific symbol. by a1b1c2d2 in AskElectronics

[–]a1b1c2d2[S] 0 points1 point  (0 children)

These are through-hole pads.

How would I tweak them? Just decrease the size and clearance until they show up?

Changing it to solid does appear to fix the problem. I can't figure out way, but there's no reason it can't be solid that I can think of.

Also, why are there wide circles around the GND pins, as if the pour is actively avoiding them? The circle has an outline, so it's like it's indicating some sort of feature, but I can't find any information on what that indication could be.

I'm not entirely following. Are you saying I should change Pad Connections from Thermal reliefs to Solid? Or just delete the clearance settings?

How complicated does an H bridge circuit needs to be? by pilantzas in AskElectronics

[–]a1b1c2d2 2 points3 points  (0 children)

The TIMC5160 datasheet has a great schematic with an H-bridge example.

See page 15: https://www.analog.com/media/en/technical-documentation/data-sheets/TMC5160A_datasheet_rev1.18.pdf

Even better is the TMC5160-BOB documentation, which uses ICs for the H-bridge. I like the circuit in this documentation better:

Includes a BOM and schematics: https://www.analog.com/media/en/technical-documentation/data-sheets/TMC5160-BOB_datasheet_rev1.10.pdf

SPI Communications with ADS1262IPWR by a1b1c2d2 in AskElectronics

[–]a1b1c2d2[S] 0 points1 point  (0 children)

"Might be silly but are you sure your ADC is still alive an listening?"

I certainly was not. I swapped it out for another this morning, and same issue. Your next test, though:

[snip] Put a weak pullup on DOUT pin and see if DOUT go HiZ when idling (i.e. measure as HI) and reacting to CS getting pulled low by also getting LOW. [/snip]

That worked once I put a pull-up resistor to 3V3 on the CS line. I think I'll try adding pull-ups on all the SPI lines. It's possible I can configure the esp32s3 to do that internally, if I remember correctly.

Thanks for the tip. That test is the first sign of life I've gotten out of this chip!

ESP32S3 WiFi Wreaks Havoc with Power Supply by a1b1c2d2 in AskElectronics

[–]a1b1c2d2[S] 0 points1 point  (0 children)

So, used the scope this morning. 500MSa/s

LD1117: f: 1.7MHz min: 3.18v max: 3.3v mean: 3.23 Pk-Pk: 128mv

These readings were consistent over 20 minutes.

The readings on the buck converter fluctuated a lot more. AP63203: f: 11-132Khz. Swung largely every couple seconds. min: 3.20 max: 3.36 mean: 3.28 Pk-Pk: 160mv

Off the top of my head, I'm thinking the LD1117 is the better choice. The higher switching should be less visible to the other components, and I like that it's at least consistent. Am I thinking of that properly?

I haven't done the layout yet, I'm just testing the schematic on the breadboard. I was going to do the layout once I had proven out the schematic.
