Re: TPM 2.0 is not always standard issue
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
That HP/Compaq 7550 isn't a Trinitron. I saw a lot of those at the schools I went to. I remember some of them having a really screwed up picture when they were new (like shaking horizontally), but...

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
Has anyone here tried the "STC" controller (the one with an 8051 clone instead of an STM32)? I keep seeing those, and they tend to be the version with an external power supply. I'm looking at these...

Re: Op-amp preamp discussion
Trimpots won't help if the imbalance constantly varies like the 100k dual gang pots that Radio Shack sold in their dying years.
