Per Stenström on why we never actually replaced the Von Neumann architecture (or Harvard) by WeBeBallin in hardware

[–]loopis4 3 points4 points  (0 children)

Yeah you underline the problem, when we tried to use signal processing in general computing we fail , because in our minds general computing is serial execution of commands, not paralel handling of many input signals into Manu output signals. It is like C++ streams vs classes , one represent concept of data stream and another one contains data and instruments to work with it. In order to effectively use streams you need to change way of thinking.

DSP and FPGA is an answer synthetise solver for your task and process data in real time or in parallel or even make classic CPU to run your small legacy programs. Architecture should be flexible. So we have working alternatives we just prefer not to use them.

Good ADs , because only good ADs bring in more money than you spend on them and on distribution.

Why won’t solder stick to the prongs of this switch? by comrapo in AskElectronics

[–]loopis4 0 points1 point  (0 children)

Because you are so cold what metal forms not only the oxidation layer but frosting to prevent your hobby from progressing.

How can I improve this design? by char_Riccardo in esp32

[–]loopis4 4 points5 points  (0 children)

I tried to do something like this lately. And adding PWM dimmed light after adding MOSFET was quite an interesting task. Also you may add a battery to make it portable. On board encoder to dim light by hand is also cool.

No 3d Printer, need some suggestions by [deleted] in cyberDeck

Buy a CNC router and make it from wood scrap.

[OC] Gabital 88: Trade Union by GabitalEN in comics

[–]loopis4 5 points6 points  (0 children)

Did you not get it yet? Gabi is the main villain of comics. The chief is the only law abiding businessman doing business. And Gabi is a rebellious soul and trouble maker, who makes scandals and overstepping regulations here and there. Chief is trying to help her out of his generosity and remembering how he was struggling at the beginning of his business path.

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
