shhh! the baby is asleep, which means the parents are up hacking baby toys…we’re following/recreating the DEFCON 26 Teddy Ruxpin reverse-engineering talk by super-hacker team zenofex and Exploiteers to bring this now-no-longer-supported Teddy Ruxpin 2017 edition back to life and maybe create some custom content as well!
our first step? parse out the SNXROM file to replace the eye bitmap frames in a ‘story file’ using python and Pillow. we just replaced em all with this adafruit logo but you could use any 128×128 RGB drawings. now that we know that works, next we’ll be poking at the audio32 format to try and decode/encode custom audio. our poking and prodding is over at https://github.com/ladyada/Adafruit_Learning_System_Guides/tree/main/Teddy_Ruxpin

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
