    What are the tunable parameters for the Unison Double Tracker? [ANSWERED!]

    Good question, I'm not sure, but it's surely set by the FV-1 so check out the various docs at http://spinsemi.com/products.html Looking at the application notes (http://spinsemi.com/Products/appnotes/spn1001/AN-0001.pdf) the clock is normally set to 32767 Hz, and delays *appears* to be...

    2sk209g alternative?

    I don't know about the 2SK209-G, but the 2SK209-GR is still available as an TO-236 SMD from Mouser. Not disagreeing w/ the other answers above, just noting...

    Canadian PCB Manufacturers?

    Ah, so if you want custom PCB makers (like PCBWay, etc), then Dead End FX isn't in that market. But Dead End FX does make PCBs of guitar effects much like what PedalPCB does, and they do ship from Canada. www.deadendfx.com

    Doesn't Dead End FX ship from Canada?

    Whatchu sittin on? (chair thread)

    What I use: Not as good as a more serious and expensive chair, but plenty comfy and an unbeatable price. I put pads on mine, to better protect the seat from tears. Note added - from Ikea

    Adding a transistor selector switch to a RangeFinder

    You could always include bias resistor(s) in the switched transistor sub-network. The switched resistors could be all or only part of the total bias resistance, but are enough that both transistors are optimally biased.

    What's up with Deadend FX? "Temporarily closed until further notice"

    Ouch, surgery... I wish him well, and a full and speedy recovery.

    What's up with Deadend FX? "Temporarily closed until further notice"

    I see that Deadend FX's website says "Temporarily closed until further notice". Anybody know what's up? I don't want to pry, but ... I'm wondering if it's a financial issue (e.g., tariffs hurting them,etc.) or of a more personal reason (e.g., just needing a break or vacation). I have built at...

    Parts Storage Solutions

    My storage solution consists of wood bins made from cut up scrap lumber and plywood, sorted by component type and value. For storing passive components, I use whatever small bags I have on hand - including a lot of reused baggies. For storing semiconductors, I use conductive baggies I bought for...

    Lock washer performance worse than no washer at all?

    When I don't want a small nut like this to come undone, I put a drop of paint on it. Having some Scottish genes, I use fingernail polish - more specifically, a color that was on sale... Very easy to dispense, and close up for the next use.

    This Week on the Breadboard: Shallow Water

    As a NASA guy, I'm sure you know that the term 'heavy water' has additional meaning outside of music. So to keep with the various nuclear sub-themes, perhaps one of the pots could be labeled along the lines of 'Fusion' or 'Moderator'? Happy holidays!

    EAGLE USERS...2026 IS HERE. WHAT TO DO?

    I would not pay for someone to email me the code + license #, as there's too high a likelihood that they're reselling it multiple times, which the company would legitimately get pissed enough to take action. But buying the physical disc + cover/box + printed license # for a modest amount is a...

    1/4W Resistor in 1/8W size?

    Yes, I've bought some as well. They're fine, and even very useful when you have to parallel two resistors to make a resistance value you don't have. I will note that very few of our circuits in normal operation generate enough current to get these resistors even close to 1/4 watt. So while...

    EAGLE USERS...2026 IS HERE. WHAT TO DO?

    Good question. I don't know the answer when it comes to Eagle, as I don't know them or their software. And I definitely don't know how aggressively they manage their licenses. But I have in the past bought software discs + old licenses for scientific software from other people, and it worked...
