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the story of the team who worked months to resurrect the distinctive voice of physicist Stephen Hawking from the long-out of date CallText 5010 boards and firmware.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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
