Re: Post your system.......
I'm surprised by how low the prices are on gaming laptops now. That one actually looks nice. I get about the same battery life on my current laptop with a 90Whr battery.
I don't think I posted my...

Re: DIY amp for speakers
Figures 13 and 14 in that datasheet show the maximum output power over the supply voltage range. I would guess that you'll get about 10W per channel into 6 ohms.
Power consumption will vary with...

Re: MGX7520 onboard graphics problem
I don't think 25 ohms would show up in temperature measurements.
Can you see what that cap connects to? The CPU takes 2.9V and 3.3V, and I would guess that the Cx5520 runs off the same 3.3V...

Enabling Intel Platform Trust Technology will run some kind of software emulation of the TPM for the few people who actually want Windows 11. I would expect it to be enabled by default on a current...

Re: new apple studio display uses capxon caps
Apple already has the cult who thinks it's cool to constantly buy new stuff (and create e-waste as a consequence), so there isn't any need to force products to fail. It's just a company being cheap...

Re: new apple studio display uses capxon caps
CapXon is unavoidable. I can only hope that their quality has improved, but I doubt it.
On top of that, the design of this monitor is insane. What are they doing with a full iPhone SoC and such a...

Re: best cheap/free scores 1.1

Re: Best video card for 2D?
Video card prices went nuts over the last couple of years (for reasons that might be best discussed in the VIP forum), so I don't think you'll find anything under $100. Right now, I see people buying...

Re: Post your worthless and/or pointless repairs
I get a little bass from it, but I think there's a dip in the response just above the port tuning frequency. I think there's still a little peak around 1kHz with the current component values (47µF...

Re: Power supply build quality pictorial. part 2
I haven't seen those 5.25" bay power supplies in at least 15 years. They were made for people who didn't want to upgrade their power supply for some reason when they got a new high-end graphics card.

Re: best cheap/free scores 1.1
I haven't seen that before. I guess it really isn't worth finding such a low-capacity flash chip or there is some application that requires the lower capacity (I've heard of that).

Re: KSGER STM32 T12 soldering stations
I don't do much soldering anymore, and even when I did solder more, I got a decent amount of life out of that $15 iron. Because of the lack of use, that Weller is about as much as I want to spend....

Re: KSGER STM32 T12 soldering stations
