Jason Fagone at the San Francisco Chronicle details the story of the team who worked months to resurrect the distinctive voice of physicist Stephen Hawking from the long-out of date CallText 5010 boards and firmware.
It is interesting to see the entire process unfold – emulating the chips and the mysterious firmware, the hard work done by Eric Dorsey and his team.
You can also get a first-hand account of the process from Peter Benie on his website. This includes the disposition of the project and code.
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.
