Twitter user @tom7 (Tom Murphy VII) has done some excellent reverse engineering of the Nintendo original (1984) NES console and its game cartridges. It turns out that you can use another computer to inject your own code into a classic system. Tom shows us how in great detail, using two models of the Raspberry Pi, in two videos:
Do you think plugging in modern computers to classic hardware is cool? Post in the comments!
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.
