    Cant find pinout for joystick pots

    Where did you get this design from? You're swapping-out a optical encoder for a potentiometer joystick, that interfaces through some other circuit to your Nintendo? Is it possible to get more information about this from the source? If you can't get more specific information about what this...

    Cant find pinout for joystick pots

    If you still have the old joystick assembly, take resistance readings while adjusting the joystick. You should be able to read the points on the old joystick, to their counterparts on the new one. Compare the old joystick readings to the new one.

    Capacitor replacement advice

    When you replace these caps, check the physical size/lead spacing. A few times now, I've not paid attention, and bought something that physically doesn't fit in the old board. Just something to be aware of.

    3D Printer

    My experience is, DOING it gets you a lot more useful information than just talking about it. A lot of us have opinions about what to do, but not many of us can argue with hands-on success. Good luck. I've been reading a lot of articles about these printers. Yeah. Doing it, is going to...

    CRT Sync Symbol

    They're not symbols I recognize, but appear to be from a drawing inside the chassis. What's the make and model of your CRT main device?

    Cant find pinout for joystick pots

    Are the pots themselves the correct resistance value? Do you have an ohmeter to check the value of the resistances, to determine the pin-out? If you're pretty sure you've got this wired correctly, you need to determine if one or more of the pots from your salvaged 3rd part controller is bad.

    HID Wiring (Headlight on ONLY when engine is running)

    p.s. You're going to get beat-up by the moderators for posting this in several other categories. Anyway, the law where you bought the bike might have required it's condition.

    HID Wiring (Headlight on ONLY when engine is running)

    I believe, that they're designed that way. I don't know if it's a legal requirement wherever you bought the bike, but I've heard that anytime, day or night, you ride, it's supposed to make you more visible to other traffic. It's possible, just like a lot of previous-rental cars that are...

    What? You've been DOING electronics work, instead of just talking about it here?

    Need help with component identification

    I'll submit my guess: Just the physical construction, and the fact that it's in a power supply, makes me think it could be a varistor. Designed to absorb transient voltage spikes. It's rare to see a cap with the leads so prominently tied to the sides of the device. It LOOKS to me, like the...

    Car Battery Load Test Results (Is this good or bad?)

    duke37 has a point. The absolute first thing I do before I try testing the electrical parts on my car is to clean the battery contacts (and cable terminals connected to them). Corrosion formed from the battery acid fumes can cause bad battery contact. I see duke37's point that bad electrical...

    I can't seem to figure out the component from this schematic

    Look. Maybe you need to google some info about how a vacuum tube works. The 'heater' is the element inside the tube that you visually see 'light-up' when the tube is powered-on. If I remember my terminology from 35 years ago, the 'Cathode or Emitter' is the element in the tube, which...

    ac to dc converter with speed control

    It might help if we knew what 'dc motor' you plan to use.

    I can't seem to figure out the component from this schematic

    It's a vacuum tube circuit. Those are the heaters to the tubes (all signified by the 'V' prefix). They're just shown all together for electrical contact purposes. You don't need to go out and buy 'heaters', the ones in your schematic are just all of the heaters to the vacuum tubes in your...

    Car Battery Load Test Results (Is this good or bad?)

    Unless somebody put one on the market that I don't know about, eKretz said what I think. Relying on a DVM for a load test is not workable. At rest, a lot of bad batteries will read 12V. You NEED to load it to test it, and turning the starter is the easiest one I know of. I'm still waiting...

    Car Battery Load Test Results (Is this good or bad?)

    I'm not a professional with car electrical systems, maybe one will input info in a following post. I can just tell you what I do. Put your voltmeter across the battery, which will probably read 12V just fine, then, while watching the voltmeter, turn the starter, to start the car. If you drop...

    Resistor question I.D.

    I think you're right on the 2.4 ohms. My comment is that it is highly unusual for a resistor to go bad by itself. I would suspect you have other circuit damage (I'd be looking at that TO-92 Pkg semiconductor tied to the resistor trace). I would think that the semiconductor failed, allowing...

    The magic of Colloidal silver

    Well, this is the 'off-topic lounge', so what the heck, .... I've heard repeatedly (which is probably worthless anyway), that silver has been used for a very long time as a real or imagined 'purification' media. There was/is a belief (I know because I know a lot of nut-cases), that silver...
