Time travel Tuesday #timetravel a look back at the Adafruit, maker, science, technology and engineering world


Road? Where we’re going, we don’t need roads. – Dr. Emmett Brown.
Here’s a look back at the maker world and beyond!

Eileen Collins, the first American woman to command a spaceship, turned 57 today. Happy birthday!


1872 – The First Patented + and – Machine that Printed Totals

US133188-0
In 1872, the first U.S. patent (#133,188) for an adding machine capable of printing totals and subtotals, called a “calculating machine,” was issued to E.D. Barbour of Boston, Mass. However, it was not practical to produce. As Mr. Barbour declared on his patent filing, though:

Be it known that I, EDMUND D. BARBOUB, of the city of Boston, county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Calculating-Machines; and I do declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which Figure 1 is a plan of case A and of device for moving the registering-slide; Fig. 2 is a section of device for moving the registeringslide; Fig. 3 is a section of case A on line a a of Fig. 1, and of the registering-slide on line Z) Z) of Fig. 4:; Fig. 4 is a plan of the registering-slide, Fig. 5 is an elevation of case A and front plate of the registering-slide on line 0 c of Figs. 3 and l; and Fig. (3 is an elevation of lever for carrying from one denomination to another.


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.
