I want to be able to capture and process an analog video signal (composite, PAL), however my knowledge of analog is very well limited.

I am planning on using a 25MSPS ADC (Texas Instruments ads801 or similar) attached to a Cyclone V FPGA so no real issue regarding how much data I can take, but I have little clue of how to connect the analog signal to the ADC beyond "mind the voltage range"

Any common caveats or design rules or reference material I should read?

My sound card just died on me, it was an Asus Xonar DG which worked fine as a replacement for my burnt integrated one. This former card had some issues, generally related to the awful drivers it provides. In essence:

  • Front panel worked... Sometimes.
  • Control app fails to load most times, disabling front panel.
  • Awful Linux support.

I'd like to buy a replacement which has as few issues as possible and, if possible, decent Linux support. I am no audiophile so I need no premium, but I have an amp connected via S/PDIF (coax or laser, no difference) so a card providing such feature is a must.

I am designing a circuit where I want to use two register buffers with tri-state outputs (CD74AC646), the outputs of which are connected to the same bus.

The output enable pins are always at opposite states. I was wondering if I could run into a problem (outputs at opposite states shorting) since the switching happens at exactly the same time (port write from a microcontroller in two different pins, cannot modify the MCU behaviour).

I need to make some glue logic between two ICs and while manually simplifying the circuit works, I'd like to know if there are tools to help me perform this task faster next time.

I own a samsung TV (smart tv with 3D glasses, led backlight) and I have noticed thebfollowing when using it as a PC monitor:

  • the input lag is severe even with game mode.
  • it performs some motion prediction resulting in visible artifacts with some patterns. Picture
  • colours at the vertical edges are blurred out to adjacent 3-4 horizontal pixels. Pictures (should be one-pixel wide, mspaint lines, only horizontal lines seem to be presented mostly correct)

All tests were performed with game mode active and any filtering options set to minimum or deactivated.

I want to know if this happens to anyone else and, if possible, a way to c

I've been removing foliage from my lawn when I noticed there were mushrooms growing under it.

They were found under a chestnut tree, close (2m away) to an oak tree forest, fall foliage is mainly composed of oak leaves.

I've never seen them before, this place is known to have poisonous amanita (panterina, muscaria), different species of boletae and lactarius. I live in SW Europe.

Shameless ripoff of this TvTropes article.

It is amazing how history repeats itself in this fabricated future.

Back in the 2014, a moral panic about the corrupting influence of sexism in videogames swept North America, thanks in part to pop culture crytic Annie Sarkeesian and his video series Tropes vs Women. (Just to note, it turns out that the content of Aniata's videos was pretty much fabricated in various ways - in other words, this entire mess was partially started by a woman whose defining work was entirely composed of lies, half-truths, omission of facts, and mo
