    Fiber Laser Making PCBs

    I have a 20W fiber laser (Xtools F1 Ultra) and tried a PCB once, but I wasn't able to get a usable result out of it. I saw a tutorial where someone with the same machine made a PCB, but all the comments were from people that tried it and weren't able to get it to work. I make PCBs at home with...

    first bassdude build

    It's pretty much just like any other pedal build unless it doesn't work first try and you have to debug, then you need to be extra careful where your fingers are going. There shouldn't be any benefit to running it at 12V over 9V, but I've had people swear 12V sounds better, so use your ears for...

    sushi box grand slampegg

    The Fdeck is one of the designs I used for inspiration for the variable HPF I put in my Finally v3, it's a great design. I'm not sure I could fit it into Grand Slampegg without going to a bigger box though.

    The More You Know

    I've been calling tee nuts hurricane nuts all this time, and it turns out hurricane nuts are something completely different. I'm learning things.

    sushi box grand slampegg

    Adjusting the cap isn't going to change the corner, the passive RC filter is only going to give you -6dB/octave no matter what you choose. If you need a steeper slope you're going to need an active filter.

    Back In Stock Updates

    E4305 is back in stock, so all PCBs with D.I. are available with transformer included again.

    Getting Started with PCBA at JLCPCB

    Yeah I've been getting mixed assembly (mostly SMD with through-hole film caps) for a while now, but last month was my first time trying a 100% through-hole board. It's funny how much you save without feeder loading fees, setup fees, stencil fees, etc.

    Getting Started with PCBA at JLCPCB

    Yeah I have a friend that had a through-hole design he wanted set up for JLC assembly and I was shocked at how much cheaper it was than my usual SMD boards (which admittedly use a large number of weird extended parts).

    Nobelium - tube bass preamp project

    Have you tried running the Nobelium by itself without the other pedals in the chain? Daisy chaining power with tube pedals can sometimes lead to noise issues.

    How do I make a via connect Ground 1 and Ground 2 planes without making them the same NET?

    What you need is called a net tie. Make a new component with a via-sized footprint and connect both nets to it on your schematic. Net ties are useful when you need to keep connections between two nets limited to one point, like controlling digital and analog ground on mixed-signal designs...

    Assuming DOUT and Din (red traces on right side) are at 10ghz, Will emi interfere with electrode inputs on the left?

    Man at page 3 you aren't even into the Scarlett Johansson pics. Looks like I didn't start commenting until around page 56, but yeah I remember reading the whole thing as it was happening. What a time to be alive.

    Assuming DOUT and Din (red traces on right side) are at 10ghz, Will emi interfere with electrode inputs on the left?

    You'll have to excuse the responses, but this is a forum dedicated to effect pedals for guitar and bass, so we're musicians, not general PCB experts. That being said a few of us actually are EE's and like looking at all types of PCBs. If you're wondering about EMI effects though we'll need to...

    Steddi, Go! - simple tube D.I.

    Sorry I missed this one, but Mick is correct. No benefit to a higher voltage for C1 unless you already have it on hand and it fits on the board. You'll be seeing low voltages there on the cathode, so 100V is more than enough. Absolutely no benefit to 0.5% tolerance resistors in this build...

    Steddi, Go! - simple tube D.I.

    100V box film caps are fine. C1 is on there, 6th from the left in the main row of components. https://www.taydaelectronics.com/0-68uf-100v-5-polyester-film-box-type-capacitor-size-small.html

    Effecth?? what kind of DSP chips

    ADSP is another product line from Analog Devices, which would make me guess it uses the same SHARC architecture as the ADAU series. If you can't figure out how to write an algorithm for FV-1, you're not going to like the development process for SHARC.

    Effecth?? what kind of DSP chips

    I've done a couple designs with ADAU1701, and there are a couple things that make me think that's not it. The ADAU1701 datasheet calls out a 12.288MHz clock for 48kHz sampling, and that board calls out a 24MHz clock. Also ADAU1701 typically uses a BJT as part of its internal regulator to...

    How do you typically Clean flux from PCB

    Everyone in my house has an electric toothbrush, so I just use whatever brush the dentist gives my kids, so I get a new one every 6 months.
