    Adding Parallel Out to Empyrean Deluxe

    I did finish and it worked fine. Here is my build report for it: Oorang Airedale. I used a 1590XX case to get all of the jacks to fit - I am not that handy with tight spaces, and only wanted to keep top-mount jacks so I didn't get overly creative to make if fit into anything smaller.

    Seabed Delay - Minor Mod for Non-PTC PT2399 and noise comparison

    I tried the PTC chip both ways. I thought maybe the noise was related, but it was still ticking after I jumpered pins 3 and 4.

    Seabed Delay - Minor Mod for Non-PTC PT2399 and noise comparison

    Just dropping an observation from my latest build so anyone looking for this might find. I made a pair of Seabed Delay (Mad Professor Deep Blue Delay) PCBs, and I used a Princeton Tech PT2399 in one, and LingxingIC PT2399 that I bought from LCSC to test. I was having issues with the LX chip...

    Even more new Tayda colors!

    I was curious to see how the Candy Metallic Gold and Candy Metallic Yellow compared, so I ordered some!. Here is a comparison in case you are curious. I like both of them, because I like my metallic candy finishes! I have tried to properly white balance the picture below - I think it gets the...

    Seabed Delay (Phido TBD) - #2

    I am trying to cut back 😜

    Seabed Delay (Phido TBD) - #2

    The campaign to put PCBs to cases is underway. Not much Phido Sound branded as these were my test builds for all the different PCBs I bought last summer, which I built over the winter. First up is a Seabed Delay - a PT2399 basic delay with only three controls. I wanted to get this one cased...

    Fuzz Aldrin hfe question

    @Chuck D. Bones I've been wandering through the rabbit hole of HFD/Lunar Module, which led me here. I am pretty new to all of this, and am curious if there are numbers around leaky or not-leaky for Germanium. In this case, what would you think of as leaky? >200 µA Ibc? at a particular collector...

    A new-production BBD, with added features!

    My guess is that the signal would be fine, as long as the duty cycle is right. The HGSemi 74HC14 is less than 0.08 at LSC...

    A new-production BBD, with added features!

    OK. Not maybe that much "live" Live enough that I can trace a signal through the SSI2100 output lead. I still need to fix the output stage signal path. On my cheap FNIRSI TC3, I don't have enough resolution to really say much about the signal quality.

    A new-production BBD, with added features!

    It lives! I was able to clip and jumper the input side of the OpAmp on my little board and the SSI seems to be working! Cool. When I went to jumper the output side, though, I have bunged the chip too much. I think I am going to just desolder and remove it and start with a fresh TL072 with...

    A new-production BBD, with added features!

    Oof. I have confirmed that I did, in fact, wire up the Op Amp inverting/non-inverting inputs backwards on my mini-board. So much for QC check before sending of to JLCPCB 😜. Walking this backwards, it looks like the SSI2100 data sheet shows the + an - in the opposite arrangement from KiCad's...

    A new-production BBD, with added features!

    I have looked at the LTC1799 as a simpler clock. Definitely interested to see how it works for you.

    A new-production BBD, with added features!

    @Cybercow and others, I made some progress today, but am stopping for the night before I am completely done with everything. I put a 74HC74 into my clock signal pathway so that I could improve the clock to BBD. I started seeing output from the BBD that matched the input - but I don't have...

    On the Aire (Hudson Broadcast EDIT

    I've finished the first complete (well mostly complete) build in a while. Here's my Phido Sound On Aire, based upon the Hudson Broadcast (Dual), using the PedalPCB DuoCast PCB. EDIT: Updated the pics with the knobs that came in this weekend.. Build A pretty straightforward build without any...

    PedalPCB Enchanted Boost 1590a

    I built the AionFX version of the ODR-C, which is a follow up to ODR-1. I definitely like the range of sound variation it offers.

    Multiple Schematics in one file?

    Definitely possible. Look at Hierarchical Sheets in help. On Mac Cmd-H, 2nd from bottom left tool opens up the hierarchy navigator. "S" let's your add sheets to the top level sheet. (the toolbar item is what looks to me like a transistor with a red + on it, on the right). I haven't used this...

    Connecting to Git?

    Thanks to @z2amiller @fetsenior @jcpst for helpful direction. Once I committed to dealing via shell first, Git has very clear Mac directions on how to establish local clones which I was able to stumble through. Especially since I have slightly complicated my flow by using SSH. At the end of the...

    A new-production BBD, with added features!

    Thanks for the tip, @Scruffie. Given that I already have my 555 clock setup on breadboard, I just have to read enough to run that through a 74HC74, which I also have. I am guessing from sketched circuit on ModWiggler, that the schmitt is dead simple (input, Qbar looped back, Q on to my BBD. At...

    Connecting to Git?

    I will try this when I have a moment. I've used command line/shell for Git, , so I guess I'll figure that out first :) I know enough on shells to be dangerous, but not much more (although I am old enough to have worked with Unix shells before there was anything but a command line)

    A new-production BBD, with added features!

    No. I have been busy mostly with my professional work, and with things that are working a bit better. I did take a second look, and the second time I was measuring, I didn't see my input signal coming through to the output of the buffer OpAmp, but didn't have time to debug the new problem! If...
