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.
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.
