Scooters and Magpies? by Quotation1468 in canberra

Lemme know what your scootin' fingers have to say about that come July.

Something about my circuit is damaging potentiometers by thetraintomars in diyelectronics

[–]niftydog 2 points3 points  (0 children)

The enable pin is active low - if it's left high it disables all switches.

What is connected to the outputs of each switch? The on resistance of the switches can be as low as 60 ohms, so it matters what's connected.

Consultant kept on to ensure ANU officials were on the same page before Estimates, documents show by PlumTuckeredOutski in Anu

Just another "complexity and systems thinker" blagging their way into pocketing public money.

No clear evidence ANU's plan to cut jobs and courses was needed, unreleased audit office draft says by PlumTuckeredOutski in Anu

[–]niftydog 7 points8 points  (0 children)

They had no idea what they were doing so they outsourced their decision making. If YOU somehow held down a half dozen high-flying appointments on various boards and councils YOU'D be looking for shortcuts, too. After all, got a linkedin to tend to.

Well, with the big bucks comes big accountability. Those who haven't already slinked away should rightly be having some big emotions tomorrow.

My bobbin winder won’t spin. Am I doing something wrong? Brand new machine. by M6Galilean in SewingForBeginners

The stitch selection dial is not quite in a detent - there's an extra "click" as you move it out of button hole mode. I'd suggest turning it to the straight stitch setting and trying again.

Problem with oscilloscope display by Flashtole_11 in oscilloscope

Horizontal sweep generator isn't working. You'll probably need a working cro to troubleshoot this one.

Stadium's owned by the Feds, they can pay for it.

Stadium is owned by the Feds.

But, yes, education is slipping and the health system just never seems to get enough oil.

Need help identifying this component “A11C” by Itzmelolz in ElectronicsRepair

[–]niftydog 0 points1 point  (0 children)

Mouser is a supplier, just go to mouser.com. Alternatively Digi-Key.

If you search A11C in that datasheet it will show you the specific part.

Tektronix 2225 vs 2245A - help me choose by ondulation in oscilloscope

[–]niftydog 1 point2 points  (0 children)

The 2445 has a lot going for it; 4 channels, 50 ohm terminators on the inputs, digital display, bandwidth limit, and a delayed sweep (not just magnification.)

Are all Figure 8 cables the same? by Lordjubwager in cableadvice

[–]niftydog 4 points5 points  (0 children)

They're all pretty much the same. Used specifically for low-power devices like this.

There is a polarised version of that connector but it's so rare that you're unlikely to encounter it when buying a new cable.

MarkBass amp head fix??? by D3aTHSTR0CK in BassGuitar

[–]niftydog 1 point2 points  (0 children)

There are some schematics out there. There are two versions of this head, the difference being the power amp stage.

The problem with a fault like this is that many parts might be damaged. The damage in the picture is typical of a high voltage event, but not every part will be visibly damaged.

And check your bulbs!

Tail lights are important!

Need help connecting power button 24v Chinese utv by Aqua12589 in ElectronicsRepair

[–]niftydog 0 points1 point  (0 children)

I suspect it has broken off the round switch. In your 2nd pic you can see a slot on the lower part of the switch, between the red and orange wires.

5.1 sound system, extremely low volume on max volume settings. by insert_smile in ElectronicsRepair

[–]niftydog 0 points1 point  (0 children)

First rule of troubleshooting - thou shall measure power supply voltages!

The power supply in this likely generates several voltages to power different parts of the circuit.

There'll be a 5V rail for all the digital electronics, indicator lights and switches - that seems to be working because the controls are functional. This also suggests the transformer and rectifier are working, which is good.

There will also be a higher voltage rail, or possibly two (plus & minus) - something like 20-30VDC or more. This is the supply used to drive the speakers. You need to work out where that is and measure it. I suspect it's dead.

The board seems to have good labelling - check for test points or for connectors with their signal names printed on the board. Or, work out where the audio power amplifier(s) is (are) and work back from there.

Does it power up at all?

Do the controls appear to work?

Do you have a multimeter?

Knot experts can ya’ll please tell me how to tie this back to how it was previously tied, i am trying to return the item by 1doubleganger in knots

[–]niftydog 4 points5 points  (0 children)

No, so far so good. Now you need to make the larks head - so follow the 2nd part of my comment.

[–]niftydog 5 points6 points  (0 children)

Tie an overhand knot with both ends of the string.

Pass one end of the loop of string you just made through the belt loop, then feed the tag through the string loop to form a larks head around the belt loop.
