So I assume, you want design your own electronics.

onkyOP•5/15/24, 2:00 PM

As per Nyquist criterion, your sampling frequency must be twice of measuring frequency, so your signal is 70 MHz, so fsample must be 140MHz, in this case you need ADC with 250Ms/s atleast, and depends on your measuring instrument memory you will have to transfer the measured data to larger memory multiple times in 16 mins as DSOs does not have large memory, this changes with resolution of ADC. Lower resolution lower data.

Hey Guys,

I am currently working on a side project, where I images and text via nfc and display it on E-paper display. I am currently using arduino and pervasive epaper display. But I am not able to display png images. What image format should i use to transfer images via nfc?

Hi Devs, I want to share with you my experiment today, so my friend wanted to print a pcb with the fastes way possible, with high quality, and we didn't want to use Ink and iron method, so I came up with thus idea, to cut adhesive warp with plotter machine and remove the excess then apply it to copper board then pure the solution... And this was the result,
what do you think about it

techielew•5/19/24, 4:22 AM

Interesting. My background is covering the embedded and IOT spaces so not a ton of experience in chip design but must say I’m surprised there aren’t at least a couple courses starting to introduce those concepts yet. @Navadeep wrote a blog a couple months ago about hardware design with AI/ML tools, and while that was at the PCB level it may include some foundational concepts that would be beneficial. I’ll see if I can find it in the morning (I’m in US).

techielew•5/19/24, 5:19 AM

Probably the same reasons you don't see a lot of Bluetooth or Wi-Fi. Lots of high-density environments with lots of noise and interference.

Accur4te•5/19/24, 12:33 PM

yeah but how much it can affect for example , the range of esp32 c3 dev board with pcb antenna gives 100m of range in an open field ( more than generic rf modules ) . IF we were able to fit high end external antenna to esp32c3 ( custom board ) and used it in a industrial setting , how much range we can get , on an approx like any estimates you can give ?

techielew•5/19/24, 12:40 PM

That’s really difficult to answer without knowing more about the environment. The problem is interference (EMI, physical obstructions, etc) in the environment.

techielew•5/19/24, 12:44 PM

In addition to interference, how crowded is the spectrum, etc. There is a reason there are all sorts of specialized protocols and technologies for industrial environments.

What sort of data are you looking to send? Check out some of the 802.15.4 options like Wireless HART and Zigbee. @accur4te

Accur4te•5/19/24, 2:15 PM

the data is sensor reading (rs485) . I was looking forward to send readings of the multiple sensors to a single gateway using espnow and then upload it to the cloud from the gateway @techielew
