I saw a video today of an ESP32 build of an oscilloscope. It looked like a fairly simple project. Has anyone here tried to build an oscilloscope with an Arduino or an ESP32?
I saw one on Amazon a year ago when I was looking to upgrade to new tech from an *old* tetronix..I saw a video today of an ESP32 build of an oscilloscope. It looked like a fairly simple project. Has anyone here tried to build an oscilloscope with an Arduino or an ESP32?
Yeah, I've seen kits on Amazon and Ali Express, which is actually what made me wonder if there were any Arduino ro esp32 projects that I could build. I did find an esp32 project for one, but all of the esp32s that I have don't have enough I/O pins to build one, and I was trying to see if I could build one with the parts I have lying around. I have an Arduino mega, which has plenty of available I/O pins, but I haven't found any code to build one with an Arduino.I saw one on Amazon a year ago when I was looking to upgrade to new tech from an *old* tetronix..

Eventually, I'll probably end up buying one, but I know that I am going to want a multi-channel scope with all of the bells and whistles, and I can't really justify that for as much as I would probably use the thing. Back in the early 90s, I worked as a broadcast engineer, and we had some really nice scopes that cost in the 10s of thousands of dollars (even back then). For what I need today, I could probably get by with a single-channel scope with a 5" screen, but I know I would end up splurging on something that I didn't really need.
And, oh by the way, if you picked up that Owon SDS7102V for $250, you got a really good deal.
I'lll probably end up with something similar, but I don't need it now. I may end up buying one of those kits just to have something to play around with in the mean time.Actually, thinking back it may have been purchased around February 2022. But yeah it was a good deal even then.
The guy had five, and had sold 2. I read the feedback of the two people that bought it and they were very happy. I posted the link somewhere on this forum, and soon the other two were gone. Mine does not have the internal battery, and had no carrying case. It may be part of why it was lower...... works great, defaults to auto and just figures it out fast.
What do you mean by this?If you get a cheapo, don't forget your DC block. I've read about some that didn't handle oopsie DC well.
