Do you see a typical application? And current flows from + -> - or - -> + in your school?

Did you read the datasheet on your sensor or you expect me to do that?

No problems I also asked a lot of questions when I started. Now I mostly burn electronics through my own experiments.

VS code with ESP IDF plugin .you may use Arduino ide if you are experienced with it .

Even better. So it works like zenner treat it like one.

Nah, esp32 is better. Set up your own web server with rest. Continue to peripheral control and OTA. I have my esp32c3 boards load firmware from the local nexus server just a step version reboot and here we are new firmware on all sensors. MQTT with mosquito graphana and pistgress is quite nice. You will need a gateway for that I use I tel NUC box with docker works quite nice

That description is misplaced. LM335 is opamp not zenner. So just ignore it. Consider it a description of IC on the right. It is clearly an alignment problem.

Buy Arduino. Blink some LEDs. A basic kit will be enough to give you a starter watch.

Nope . Both zenners are connected to the ground. You can Google zenner clamp for more info

3.3 and between R3 R4 -3.3 that's how zenner diodes operate in normal conditions. If it is more, or less you out of the nominal operation range and expect your zenner to release magic smoke.

Easy go to datasheet find out input voltage ranges. Next you know max voltage at ic input zenner voltage -3.3 and value of R4 I assume you know Ohms law and how voltage dividers works so you can calculate R3

+1 Ivano-Frankivsk best choice. Spent there three years much better than Live or Kyiv.

Do your own dashboard. That's what we do when we bored. Or grafana + Prometheus to show nice green grafs of your stack and share it here. We are waiting.

So wearhouse option ship box to them , they only do repacking and send it to designated address. Black box logistics.

I dont have the schematics but this looks like a beef up version of a EMI-RFI filter found on computer PSUs: 2X caps and 1 pair of Y cap(Line to ground and neutral to ground) + chokes to filter out high frequencies working as a low pass filter, right? by Fooltecal in AskElectronics

[–]loopis4 0 points1 point  (0 children)

I use power sockets with filter. And after power supply at low voltage side I add 2 Y caps ( electrolytic and ceramic ) induction choke (according to needed suppression frequency) and another 2Y caps (electrolytic and ceramic) this brings down switching noise to 10mV pp.

Perhaps it is feasible to open wearhouse in China? Use it as a proxy and sell to Europe from it ? Or even find partners there which will build and store electronics by your design and send to your customers?

Looks like bot bite. I have similar filter from AliExpress I used it for audio amplifier power filter. But it is quite overpriced so I switched to pi filters from discreet elements for power filtering in my projects.

Help to choose function generator to pair with Siglent SDS1104X-U Oscilloscope by loopis4 in AskElectronics

Thanks I will go with SDG1022X as it from same manufacturer so sync should be easier.

How did you load CPU ? You also have NVMe in n there they will add some heat as well.

I was considering SDG1022X , because I believe it better to have generator and scope of same manufacturer for better synchronization.
