My TV has this output, this isn't my photo. What speak stuff do I need to have a line for this?

Dang, this was so cool back in the day. Sadly it's going in the garbage now. I got this around 2011 when watching TV on your phone was actually difficult. It was very hard to find what you wanted to watch and even if you did find a stream it was usually low quality and disconnected alot. This was called a sling box (not to be confused with sling TV service). This box hooked directly to your cable box. You could launch the app anywhere and get all the same channels with a builtin digital program guide. No monthly fee, you just had to purchase the box for around 250. Only issue was if someone was actually at home watching TV they would have to watch whatever channel I was watching lol. They discontinued the box in 2022 so it is no more. Other than the guide, the box seems to be doing all the legwork on my end so they shouldn't have flipped the off switch. I assume it must have cheaper than deleting the guide our. .I miss you old friend.

I bought this venturer portable dvd player (PVS1262) at goodwill today. The screen works and I can get my CDs to play so I don’t think it’s a mechanics problem. When I try and get a DVD to play it says “no valid disc”. It’s a Canadian dvd player and I’m in the US so it shouldn’t be a region issue, I also checked the parental ratings so that’s not it. Wondering if y’all have any ideas or solutions?

Device for demonstrating the properties of electron beams in school physics classes.

The gas-discharge tube contains a hydrogen generator and electron gun.

The device is based on the principle of interaction between the electron beam of the gas-discharge tube and the homogeneous magnetic field created by the Helmholtz coils. A beam of electrons is created in the gas-discharge tube by means of the electron gun. Its brightness, magnitude, and shape are controlled by the "Anode" and "Focus" knobs. The position of the electron beam relative to the magnetic field lines can be changed by rotating the gas-discharge tube around its axis. The magnitude of the magnetic field can be adjusted by changing the supply voltage of the coils.

Hi! I recently turned back on my Toshiba tecra m4 after it had a fatal hdd failure and I lost my data. I am looking to put windows back on it but when I go to bios or a different setting manager it starts to glitch like insanity! Is the ram bad or am I cooked!
