    This is a great project, thanks for sharing! Trying to replicate it. I have a ESP-network related problem: programmed ESP with my SSID and Password from my cell phone provided network, got message" WiFi Connected" from the serial, but no response from the webpage (PC is connected to the same network). Tried to de-activate firewall with the same result. Could you provide any hint pls ?

    • @DoctorVolt

      Can you at least "ping" your ESP32? Maybe it didn't get an IP or there is some authentication problem.

    • @dk-fn2on
      @dk-fn2on 6 дней назад

      ​@@DoctorVolt Thank you! Actually the ping is quite unstable, from 0 lost to timed out. The wifi signal is strong. Ping statistics : Packets: Sent = 4, Received = 2, Lost = 2 (50% loss), Approximate round trip times in milli-seconds: Minimum = 208ms, Maximum = 211ms, Average = 209ms Tried different PCs in case, the same issue. (In case tried a demo of a simple webserver on ESP32, it is working fine) Could you give your guess where to dig pls?

    Ja, ich habe ein sehr grosse "Problem" mit diesen Only 16 KB VRAM "SEGA Mastersystem"! Da damals SEGA zu geizig gewesen ist ihren schönen neuen "System" da sofort 32 KB oder sofort 64kb "VRAM" dort einzubauen! Nein, es waren nur 16 dumme KILOBYTES als VRAM!!! 256 mal 240 pixel in 32 Farben aus 64 Farben ist zwar super GEIL ,aber nicht wenn das VDP "VRAM" von 16 KB RAM DA nicht ausreichend ist! eine neue NO-Limit "VRAM" Hardware Platine könnte sowas dummes sofort ändern ! Durch einen billigen "PI PICO" CHIP der in seinen eigenen Arbeitsspeicher dieses 16 KB "VRAM" FENSTER stark erweiterter kann ,und der Programmierer beliebige 3D Funktionen dort durchführen könnte,wie den MODE 7 bei einen SNES! Sowas als kleine billige ADD-ON Hardware "Platine" wäre natürlich bei bekannten Online Auktionen,ein schöne einfaches "Geschäft" alle für Hobby Mirco Elektronik BASTLER... DER echte "3D Turbo" für alle alten TI9928,9938/9958 Systeme wie auch einen SEGA MASTER SYSTEM!

  • @ruhrpottradio
    @ruhrpottradio 9 дней назад

    hallo doctor volt, ich finde dein projekt echt super und ich sehe du hast ein herz für alte RETRO COMPUTER ???! hier meine idee: Und es wäre auch sehr super wenn das sehr wenigen dumme "16 RAM VRAM" da mit einen schnellen PI PICO vielleicht "emuliert" werden könnte ??? ala eines c64 Kungfu oder gameboy flash... Sowas wie NO-Limit VRAM "Emulation" wäre da für alle alten RETRO Computer Systeme wie TI99,MSX 1,2 und das SEGA MASTER System DA super geil!!!! Besonders da so ein moderner "PI PICO" Chip kaum etwas kostet,okay plus einige handvoll level shifter chips für 30 cent... aber wir wissen ja alle ,das ein schneller DUALCORE "PI PICO" CHIP sogar dann die harte MATHE RECHNEN Arbeit als neuer SUPER FX "Co-Prozessor" für sogar 3D ,das VRAM "Doppel Buffering" und weitere sehr interessante "SUPER FX" EFFEKTE dann machen könnte...z.b. DATEN nachladen von SD karte dazu mehr eigenen PI PICO "SPI" RAM... NO LIMIT VRAM-wäre SUPER GEIL!! Besonders für mein sehr altes "RETRO" Lieblings System "Sega Master System" was da aber 32 Farben aus 64 Farben darstellen kann, wäre DASS die beste "TOP" HARDWARE Knaller IDEE!!! Auch wenn dann die beiden alten RAM Chips dann rausgenommen wie gesockelt werden müssen,ABER der Aufwand ist dann 100% wert,da aus den kleine 8 BIT SMS dann ein richtiges SNES wird!!! Sowas wie "SUPER FX VRAM " wäre auch eine super Hardware Erweiterung für alle o.g. nur 8 BIT RETRO Systeme ohne genügend "VRAM" Speicher wie auch CPU Rechnenpower.

      Die Idee klingt gut. Damit wäre vielleicht sogar Videowidergabe möglich, wenn nicht der VDP, sondern der Pi Pico selbst das emulierte DRAM beschreibt.

    Okay. Open questions: - What about soldering to some pads to turn the phone on and off? - What if the phone doesn't want constant voltage? Seems to be especially a problem when booting up but I also heard about devices where the percentage still decreases over time... I think the temperature contact(s) should somehow be taken care off... - What happens if somebody puts in a charger at the USB port while the phone is powered by constant voltage instead of by a battery? Will that just be fine?

    • @muellerhans
      @muellerhans 10 дней назад

      Ideally I would like to have a solution that allows to either connect some random battery (of the same type ofc to keep it simple...) or a power supply thus that a phone that stays at one place for the majority of time could also be taken with to somewhere if necessary.
