Homo sapiens to Homo Ludens

A long, long time ago a bright ape figured out that by climbing down from the trees he could more easily master his life, and that of others……Homo sapiens wanted something else, and better. He started to play. Homo ludens was born!

Homo sapiens to Homo Ludens

  • Homo ludens radiactivus – amateur radio
  • Homo ludens radiohistoricus my antique radio collection
  • Homo ludens electronicus – electronic projects
  • Homo ludens aeromodellisticus – model airplanes

Transformers and coils: This is not a building project, but a short and concise lesson in how to design electromagnetic parts. It’s much simpler than what you may expect!

Thermal design: A short course in keeping electronic parts adequately cool.

A 40 meter SSB QRP transceiver

“This transceiver was conceived as a power-efficient, small, lighweight unit to be carried in the backpack, along with antenna and battery, for use during trekking and mountaineering trips. It had to be reasonably rugged and reliable, and perform well. Furthermore, I wanted it to solve all the problems the old DSB transceivers had, such as frequency instability, distorted modulation, lack of sensitivity and selectivity, and others.”

Evolution of The SmartWatch

This post was made in relation to the TI Chronos and Casio watches, The early Smartwatches.

This is not a HandHeld Gizmo but a Gizmo that Holds your Hand. Gadgets that Cling to the Body. Wearable Wireless Computers. The first Smart Wristwatch according to my knowledge was created by Casio. It was not as smart as the chaps below, but had many functions including a calculator and calender,

Release of databank telephone number storage wristwatch CD-40

January 1984 – “Casio released watches with various advanced features, including a calculator function (C-80 released in 1980), and a dictionary function (T-1500 Walking Dictionary released in 1982). The company wanted to see the wristwatch evolve from a simple device for telling time to an information device on the wrist.”

“This watch further advanced the concept of an information device on the wrist, and became a major hit product, selling a record total of six million units in the five years after its release.”

A smartwatch or smart watch is a computerized wristwatch with functionality that is enhanced beyond timekeeping, and is often comparable to a personal digital assistant (PDA) device

eZ430-Chronos wireless watch - TI

When i saw this i remember my High School friend, he had built an advanced DIY Wrist Watch with LED Display and Radio, there was a temperature display too. A Gizmo WristWatch around 1980!

This Gizmo got many students wildly interested in Electronics. He also developed a Learning Kit ‘Chip Chap’ for 555. An Innovative Education Kit Developer Dynam was making it..

Here is one such Temperature, Wireless, USB Data Logger Watch Development Tool. But for an entirely New Generation.
