A Computer the Size of a Home: ECHO IV from 1966 #Retrocomputing
This year we celebrate the 50th anniversary of a home computer built and operated more than a decade before ‘official’ home computers arrived on the scene. Yes, before the ‘trinity’ of the Apple II, the Commodore PET and the Radio Shack TRS-80–all introduced in 1977—Jim Sutherland, a quiet engineer and family man in Pittsburgh, was building a computer system on his own for his family. Sutherland configured this new computer system to control many aspects of his home with his wife and children as active users. It truly was a home computer—that is, the house itself was part of the computer and its use was integrated into the family’s daily routines.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
