Re: cheap but good thermal paste?

Suspect a dying fan. Most fans in my experience don't die outright, they slow down, or intermittently stop and restart when someone is watching.

I wouldn't have ever noticed this behavior, but...

Re: cheap but good thermal paste?

Heh, spotted the non-gentoo user.

If you run gentoo, you pretty much need to recompile a good part of your system at least once a quarter. I have given up on compiling the larger ones like...

Re: Signal Tracer - Requesting input on requirements

This may be my new motto.

Well, I decided against using my crusty 20 year old perfboard, and the new perfboard arrived 2 days ago. It's going together pretty well. Unfortunately, my garage has...

Re: cheap but good thermal paste?

Does thermal paste type really make that much of a difference? I'd think you would get more performance from replacing the fan on the heatsink or adding fans to the case. Unless we are talking...

Re: New tool to find short capacitors on motherboards : shorty with display

My LCD for this project just arrived today, it's much smaller than I thought it would be. This project should be able to fit on some perfboard. If you want to build it on some perfboard, I'll go...

Re: [FAQ] Atten 858d problem S-E (or 5-E) or stuck in 498'C.

These machines are really hit or miss. I'm looking at getting a T12 soldering iron station, it seems that kgser is the original hakko copier and seem to have the best ones. Eruntop looks like they...

Re: Drilling holes laptop bottom

I think the thin plastics involved in laptops wouldn't take kindly to drilling holes. Unless it never left a desk, it would disintegrate in a short period of time.

If it never left a desk it...

Re: Should I use low ESR caps in TV power supply board, or will any kind suffice?

That's what I do. Caps are pretty cheap, it's not worth my time to try to chase down one bad one. Plus, caps are generally consumables, they have a finite lifespan, if one is bad, others probably...

Re: Signal Tracer - Requesting input on requirements

So the usual is to set your gain to a set amount with no distortion for a certain type of input. That makes sense. In this case we could be dealing with different types of input though and...

Re: Signal Tracer - Requesting input on requirements

So a theoretical question. Why would you, by default, want to set your gain to a static value and weaken the input signal instead? Seems to me that you would want to leave your good input signal,...

Re: Max resolution out of DVI-D port.

I don't know all the details, but check the BIOS. My BIOS has an option to send digital sound to the on board video card or to an external video card.

I just checked, both your cards and mine...

Re: Signal Tracer - Requesting input on requirements

Yeah, this chip would have worked great, except then it picks up AC hum too, probably adding too much non-randomness to it. Last I heard of this (and it has been a long time) people were cracking...

Re: Signal Tracer - Requesting input on requirements

I went and picked up the new chip, it wasn't JRC, but it was a natsemi lm386-4 (the 1w version). I put it in, total silence at 20x gain and zero volume. At 200x gain I start to get some AC hum from...

Re: Signal Tracer - Requesting input on requirements

It's white noise. Same level of white noise if the volume is all the way down or turned all the way up (audio input hooked up, but no sound playing). My compuer speakers have white noise if I put...

Re: Max resolution out of DVI-D port.

To follow up, I swapped a cable from another machine, which I replaced with a displaylink cable. The cable I had (pretty sure it was just a generic monoprice dvi-d to hdmi cable) passed audio over...

Re: Signal Tracer - Requesting input on requirements

I shortened the cables on the pot to around 1 inch, no change in noise. Then I took out the 10uf cap to change gain to 20x instead of 200x, replaced the 1M pot with a 10k pot and bypassed the 4R7...

If you liked that, you should see the new pic! If I could get this working, I'll probably coat it with some liquid tape. Either way, it will be 4 point mounted in a protective plastic box with 10mm...

Re: Signal Tracer - Requesting input on requirements

Thank you!!! I have been trying to trace out what has been going on, and I'd unplug the speaker from the board so I could flip the board and take a look, turns out the speaker plug was reversed. ...

Re: How to desolder transformer from PCB?

Dilute the lead free solder with Pb solder, then suck that out. Admittedly, those holes look pretty tight, usually transformer holes are a bit larger in relation to the wires. Normally, I'd use my...

Re: Repurposing a 2004 Athlon 64 system in 2021

I haven't worked with them much recently, but nodeMCU modules have wifi and are pretty cheap (under $3 if you buy from china). If you go the arduino route, that would be an easy substitute. When I...

Re: Repurposing a 2004 Athlon 64 system in 2021

Why would you need to connect them all together? If you wanted them to come up at different times, you just set the timer longer. This would require one full unit (timer+relay) per computer, but...

Re: Repurposing a 2004 Athlon 64 system in 2021

Wouldn't cost much to hook an arduino up to a relay, or even a cheap timer that can run on 120v and pack it all into a junction box.

timer + relay module, requires DC power supply...
