The poly case is “square”, canvas tuner has a taper like most Hammond enclosures. Wow $14 each.

Can someone identify what enclosure the Walrus Audio - Canvas Tuner uses? It's somewhere in between a 1590A and 1590B/125B.

Here's a :

I got it to work. @Stickman393's schematic is correct. I took the Anode tab on the D_FLO and connected it to the LED SW tab. Left the switch LED and LEDR (4k7) open. Of note, originally I used a 1k for the LEDR (6k8)... I find this works best on the 3DPT LED's. But this doesn't work in this...

Thanks for the help. I’m leaving town for a week, I’ll try this when I get back👍

Just built a Caesar (Walrus Julia) chorus. Normally this has 2 LED's: on/off and pulse rate. The Pulse LED is the D_LFO in the below schematic. I was hoping to combine these into 1 LED that only pulses when it's ON - and is off (and doesn't pulse) when it's off. I tried, but I couldn't figure it...

Tayda does square shapes. There’s probably a Tayda template in the PPCB template area.

I forgot about this, been working on other stuff. Playing it tonight for a while, mostly nice. It seems to have some low end problems. Not sure if I did something wrong or what, but it tends to fart out the low notes if I push them. Ideas?

Hi, I'm designing a guitar tuner based on an ESP32 microcontroller. Trying to understand how much gain to apply, I seached around on the internet looking for different pickup type outputs... and really didn't find much. So I measured all the guitars I have access to on an Oscope. Maybe this...

Rough cost Latching relay is $4.50 Non latching $1.50

Yeah you’re right. I think

Huh. Can’t believe I missed that. Thanks!

Does the PPCB latching relay always power up the same state?

Oh ok. So they both function the same. What’s the advantage of one over the other?

Ah so non latching you have to hold it down. Got it👍

What is the difference between using a latching vs non-latching relay? https://www.pedalpcb.com/product/pcb393/ https://www.pedalpcb.com/product/pcb394/

https://www.pedalpcb.com/product/pcb394/ The SW tab isn't on the schematic. What does it do? I think I'd like to hook it up to an Arduino and use it as an on/off switch. Yes?

Are there any momentary foot switch options that are smaller than the standard 3PDT? It only needs 2 contacts...

This isn't necessarily for Arduino, I'm actually working on an esp32 project. But there are SO many display options. Questions to consider: Difference between LCD, OLED, TFT, etc. Many are touch, some aren't. Some have integrated processors (esp32), most don't. Lots of different sizes...

Yeah I was thinking about something similar to this, standoffs up and down. You say a couple PedalPCB projects... can you point me to one?
