Puppet Mode Teddy Ruxpin @Raspberry_Pi #PiDay #RaspberryPi

Made by Donald Willingham  via hackster.io

My wife had a Teddy Ruxpin as a kid until it took a nose dive off of the top bunk of a bed. Shortly after, I ran across a hackaday reference to Tinkernut’s Teddy Ruxpin. She almost immediately order a pair of ‘not functioning’ Teddy Ruxpins off of ebay. One was a World of Wonder (Version 1 metal tape deck), and another was a later YES! Entertainment version. An audio cassette was included.

I followed the Tinkernut video for how to replace the servos. I used some Tower Pro SG90 servos. Ensure you save all the gears, as some of them need to be re-used. It might be nice to 3d-print replacement servo enclosures, but the hot glue is still doing it’s job.

Instead of using an Arduino to generate the PWM signals to the servos, I used ServoBlaster on a Raspberry Pi. I know there are PiHats that generate better hardware PWM signals, but doing it in software on a Pi 3 is sufficient here. Be sure to pay attention to the ServoBlaster’s output. Ensure you get the pin numbers and the GPIO numbers straight.

I hooked up a USB to Playstation 1-2 controller adapter, and an old Playstation controller. I wrote a perl script to read the joystick inputs, and map them to joystick outputs. Since the joystick has two analog X/Y sticks, I mapped one to the eyes, and the other to the mouth. The mouth is made up of two servos, so I just send the same value to both.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
