Aber mein grösstes Elektronik LERN- Problem ist ,das ich in meinen sehr langen BENUTZER Computer Leben,die damaligen Z80 Home-Computer als minderwertige wie auch langweilige "Computer" angesehen habe,und deshalb MICH auch NUR bessere 6502 Home Computer da interessiert haben wie C64 oder später Amiga,die eben mehr Grafik und Sound den Benutzer "präsentiert" haben anstatt Z 80 computer wie CPC als PC Clone,oder die langsamen MSX 1 oder 2 Computer,die auch in den 90er Jahren in Deutschland ziemlich rar wie sündhaft teuer gewesen sind... LERNING by DOING ??? Dumme Konstruktions-Fehler will ich hier nicht bezahlen... Nein,ich will hier nicht einen teuren wie dummen "4 Chip Z80" Bausatz bei Ebay z.b. da kaufen ,da ich diesen LERN-BAU-KASTEN ich da ziemlich mangelhaft wie super dumm finde: Der ATMEGA der mit seinen nur 8 Bit Port der direkt am Z80 Datenport anschlossen ist also ein nur "BYTE für BYTE" übertragung ,anstatt gleich per eigenen schnellen ATMEGA "DMA" aufs ganze vorhandene "RAM" mit einigen billigen 74LS373 "Latch" 50 cents "Chips" ,da den langsamen CMOS "Z80" benutzt für höhere BYTE der Daten "Zieladresse." ja, nur weil der "justforfun" z80 entwickler an diesen dummen vielleicht "50 cent" 8 bit- latch 373 chips gespart hat,aber für sein ABER "nur 4 Chip BILLIG System" da gleich eine sehr teure "CMOS" DELUXE Z80 VERSION ABER vorraussetzt !! Ach,ja ich würde hier so gerne diesen alten Z80 "SEGA MASTER SYSTEM" wie auch jeden so ähnlichen Z80 System als "MSX 1" wie 2 System gleich einen superschnelle "CPU turbokarte" per da den NACHFOLGER per CPU "Z180" verpassen samt einen modernen ATMEGA als I/o controller der sofort "moderne" Anno 2000 Geräte wie SD KARTEN oder PS/2 Keyboards,MAUS sowie einen topmodernen "SPI PORT" für modernen ADDON Hardware z.b. MP3 player da möglich machen würde samt einen "PICO PI" als neuen "VRAM" CONTROLLER ,um hier die lausigen nur 16 KB VRAM massiv zu erweiteren z.b. bei so uralten Computer wie CPC, TI99 oder MSX1,Colecovision oder das Sega MASTERSYSTEM. Nur leider fehlen hier die passenden HIGH IQ FACHEXPERTEN für diese sinnvolle AUFGABE!🤔

Wo sind die vielen kreativen Hardware entwickler die hier uralte Computer so "modding" wollen ? Die da eben da einen neuen spottbilligen nur 5 Dollar "PICO PI 2" dafür nehmen ,auch IHN als preiswertes "RETRO CHIP "REPLACEMenT" für 50 jahre uralte rare teure TI99,C64,CPC,MSX 1/2 oder SEGA MASTER SYSTEM Videochips aber mit mehr möglicher GRAFIK LEISTUNG dann benutzen werden und dabei sollte auch nicht den modernen DVI oder HDMI Anschluss nicht vergessen werden ,wenigstens ein altmodischen "Video out"!

    I've been waiting for this since the last video. But this seems a bit complicated. I've looked into writing my own java app and found a serial port library that supports arduino and all the common USB to serial converters. Didn't have the time to test it yet, but just having one app with integrated serial communication seems much simpler than writing python code, having to wrap it up into an app and then using a second app to do serial over tcp.

    Somewhat more involved than using a web UI on a phone, but the IP socket connection would definitely be more responsive than HTTP. But TBH the wired USB connection is kind of a downside - this would really be more appealing if it talked to the controller via radio like ESP-Now or PainlessMesh.

    • @DoctorVolt

      It depends on your project whether a wired USB or wireless connection is better. If you run an IP socket directly on an ESP, the app can also communicate over wireless without any issues.

    to me it seems just pointless that a lot of people in the comments compare a rpi with a smartphone. it is just they are made for different things. rpi is a lot more accessible platform to develop on, just because it was made for it. its made in a way that beginners can actually start to use linux and do some cool electronic stuff. using a smartphone is not the best way to prototype something, probably 90% of the time a rpi is just better because of its built in capabilities, like having gpio exposed and running an actual linux distro. and i say this as a linux programmer, that has experience with android too. probably you won't start your first blinking led writing an android app...but with a python script or something else . anyway, this is a cool project, keep it going

    2:07 Shorting the LED to turn it off is not a good design practice, because current is always flowing even when the LED is off. A better approach is to instead connect the LED cathode to the transistor's collector, and let the transistor pulls down the LED to turn it on. In this manner current flows only when the LED is on.

    Interesting microscope. It is better than usual optical microscopes. Because it can create 3D images. I think it is possible to modify the program so that the result will not be a 2D picture, but a 3D model that can be rotated in a 3D editor (to show the 3D structure of the material). The most interesting objects for scanning are insects, a fly's head, dragonflies.

      @@DoctorVolt thanks brother. I don't like the idea of not having the source code. I don't think I can bear the idea of my app having more elements in it than I intend for it to have ya know... Don't know what else they'd be putting in it. I kinda feel the same about this packager you speak of.. until I know how it works precisely. But I guess I'll just have to yolo!. Because I'm not very educated on programming and stuff.

      @@DoctorVolt Your videos are something I have been recommended to watch multiple times, and I'd just play and gloss over your vids as nothing more than entertainment or just to occupy only for passing time. But recently I've been learning these fields, electrical/semiconductors, programming, architecture, and whatnot. And I'm loving to revisit your vids, now that I can actually grasp them better gradually. Thank you! You are awesome!

    Can u explain why u coded "bool pressed = !digitalRead(INPUT_PIN)"? Why did u assign the negated pin state?

    • @DoctorVolt

      Because the input pin is configured as "INPUT_PULLUP". That means that the input level at the pin is zero when the button is pressed. So I inverted it to get a "one".
