At one time, telegrams were the primary means of high-speed, long-distance communications. They were the email of their day and, like any widely used service, customs and rules grew up around them. A 1928 booklet by Nelson E. Ross titled How To Write Telegrams Properly details some of those rules and conventions. Not solely about writing telegrams, it also serves as a historical snapshot of telegraph services in 1928. The many topics covered include:
How to Save Words
Tolls – How Computed
Extra Words and Their Avoidance
Collect Cards and Their Uses
Messages for Persons on Trains
How to Send Money by Telegraph
“Telegraphic Shopping” Service
The range of telegraph services available at the time was quite impressive. I knew it was possible to send money by telegraph (think Western Union), but I never knew that telegram delivery was possible to a person on a train. Similarly, I had never heard of “Telegraphic Shopping,” seemingly a 1920′s e-commerce prototype providing a way to buy any “standardized article from a locomotive to a paper or pins.” I wonder how far that idea developed.
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.
