Replace the Heating Coil of a Cosori CP158-AF Airfryer

Bild
Starting Situation  Air fryers are fantastic kitchen companions - until the day you make one of those rookie mistakes that leaves you staring at a melted mess. That's exactly what happened to me when I carelessly tossed in a food package without checking whether it was safe for high-heat cooking. The result? A thin layer of plastic fused stubbornly onto the heating coil, releasing an unpleasant smell with every use and, more importantly, raising real concerns about the safety of anything cooked inside.   Cleaning it off was not an option - once plastic bonds to a glowing-hot coil, no amount of scrubbing will fully remove it without risking damage to the element itself. So the only sensible fix was a full heating coil replacement. Replacement Heating Coil You can order a replacement on e.g. AliExpress => "Air Fryer Heating Element, 1700W 220-240V" => compare with your old coil if it complies with the specifications      Repair Instructions   Unopened D...

Connecting a Commodore 64 to the internet might sound like science fiction, but with today’s microcontrollers, it’s surprisingly simple.  Using a NodeMCU v3 ESP8266 and the open-source pastbytes modified  Zimodem firmware you can give your C64 full WiFi capability — letting you connect to BBSes , transfer files, and even chat online, all without a physical modem or phone line. NodeMCU v3 ESP8266 Flash the Firmware to the ESP8266 You need the esptool to write the Firmware (Zimodem) to the Microcontroller: Install in Python :  pip install esptool Command to flash the firmware:   python -m esptool -p COM_PORT write_flash 0x00000 .\zimodem\firmware.bin  Erase the ESP8266 NodeMCU Flash Hold the ESP8266 BOOT/FLASH button python -m esptool -p COM_PORT --chip esp8266 erase_flash When the “Erasing” process begins, you can release the “BOOT/FLASH” button  Build the Turbo56K Modem Userport Turbo56K Wifi Modem We just need to connect 5 signals: TX , RX , GND , RT...
