Thank you! 🙌🏻

Beautiful job, kudos! PS: I just saw the bottom detail with my username! haha, shouldn't it say "developed by XTS"?

Yes. Using a voltage divides as that gives you a source impedance of 5k ohms (10k and 10k in parallel). It means it drops 5V for every mA of current you use. You should try with a low impedance source, as a regulator IC (78L05) or a power regulation circuit.

I was going to reply, but JTEX stole the words from my mouth. So all the above for me too!

PCB design is not just to avoid having hundreds of wires connected by hand. In the real world, the wires and PCB traces are not perfect conductors: every trace/wire induces an electromagnetic field that affects all the other traces/wires in the design. That's why PCB designers use techniques as...

Also, p There are noise and signal integrity reasons too.

I'm an electronic engineer. A mechanical 3PDT switch hand soldered (specially if you are soldering individual cables by hand) is definitely way more prone to failure than a relay. As a hardware product maker, when you think quality, you don't think a design that is easy to fix. You think a...

I'm from Argentina and I'm used to this crap already. I ordered some PCBA last week. Payed 85 US dollars in product and 40 dollars in shipping on the JLCPCB site (used DHL express. Mail shipping was 30dollars and takes 2 to 3 months to arrive). To get it into the country I also had to pay 30...

Maybe you are overheating the componentes when soldering them? Pictures could go a long way here..

If using X7R, select the bigger size possible (according to the design and design needs) to avoid the capacitance variation with DC voltage applied. Also, X5R and X7R have piezoelectric characteristics (microphonic), so are avoided in the signal path if possible. COG have no piezoelectric...

ChatGPT is great help for this. Also, if you can get 1k5, two in parallel gives you exactly 750ohms

RoHS international laws sometimes make no sense, considering modern batteries generate lots of contamination and they are allowed. Even heard once that chinese battery toys started to include batteries just to make the contamination from the batteries anothers country problem. From our world...

That would be great!

These 2 are actually related. The impedance you can see as how easily current can flow to/from a point in the circuit. An output of an opamp, the emitter on a Bipolar transistor, ground, etc. are nets that can take/deliver high currents, and those are ideal for long traces. In the other hand...

Instead of worrying some much in aesthetics, I would consider functionality. Try to have ground fill. Good for noise and signal integrity. Keep high impedance nets' traces short. Low impendance nets can be long and not have induced noise. Keep the feedback networks on amplifing stages as close...

I suspect the first versions of the Diezel pedal may be different from the later units. A good start point could be opening the pedal, and just take pictures. No warranty or devolution policy should be affected by doing this, and we will be able to help you from the pictures a lot more

Closes to flat setting: Presence and deep in 0. Bass and Treble at 0. Mids at 10.

The relay coil is connected directly to V+. If you want it to switch, you need to use the output signal from the 555. And check the 555 connections, some stuff is connected incorrectly. Compare it against the standard bistable 555 circuit.

I used KiCAD on windows, linux and mac, and I have nothing but good things to say about it. And it's not only free, but open source!
