Video on oscilloscope

[@dio492j]

I'm glad I found this 7 years later

[@DiamondSaberYT]

Oh yea

[@touhoudelivery3831]

Same feeling

"So, how's the testing going, Joe- what's that?" - "what's what?" "That, on the oscilloscope" - "oh yeah, that..." "so, what is it?" - "touhou"

[@ajemajh]

of course this is the first thing i would play on this

[@badassman5562]

Literaly the first videogame was played on this kind of machine

[@szprink]

i thinked only Chuck Norris can play videos on oscilloscope...

[@photogeek100]

+Miles Prower Well, Chuck Norris can play video on anything (shovels, toasters, etc), I am not anywhere near to be that cool.

[@dallase1]

Why would Chuck Norris play video games? He's no t a computer nerd or video gamer, he's a martial arts master.

Good Apple!

Is there really a need of such high frequency OPamp ? I cannot really get the AD8031. I do however have plenty of slow OPamps like LM324. At worst I can get the AD8032 (basically 2xAD8031) which is available in some internet stores. What kind of frequency do I need for such opamp ? I may browse some sources to find one that is better available.

[@photogeek100]

TV signal bandwidth is a few MHz, so you should select a pretty quick opamp to handle this frequency. I just happened to have AD8031. As you mentioned, AD8032 should work just fine. I am not sure where are you located, but I would recommend www.findchips.com/search/AD8031 to check electronic components cost and availability. Looks like AD8031 costs about $3 USD and readily available from multiple online vendors.

[@Pawelr98]

I can get LM833 or NE5532 each below 1USD in my local electronics store. Both are 10MHz opamps which should do for PAL or NTSC signal. My oscilloscope is C1-107 (S1-107) which is 1992 russian portable-ish CRT oscilloscope with a bandwidth of 5MHz(it should be able to go bit higher than that). Got it for around 45USD as my first scope.I'm located in Poland.

[@photogeek100]

Both op amps should work just fine. I am somehow familiar with C1-107, but does it support X/Y mode? Otherwise you have to modify the schematic a little to manipulate the main trace, instead of doing a full X/Y scan.

[@Pawelr98]

It does have X/Y mode. There's X input on the side of oscilloscope. I just have to flip the switch and the X input changes from timebase to external input. By applying DC voltage I was able to move the dot left/right depending on voltage level. I also think there's Z input. It's not directly marked but by analysing bloc diagram from technical documentation I came to conclusion that it may have Z input. There are two inputs marked by "0.5-5V" and "5-50V" as well as a switch. Bloc chain leads to Z control module.

[@photogeek100]

Nice! With brightness control the picture should look a lot better, like an actual TV.

HOW

[@a_naotenhonome780]

Nice

[@DanilaSample]

looks like fake. any prooves?

[@photogeek100]

How about schematic and circuit explanation? Is it good enough prove? boris0.blogspot.com/2013/09/video-on-oscilloscope.html
