Google celebrates the 155th birthday of Heinrich Rudolf Hertz

Google Doodle Hertz Symbol

Today’s animated Google Doodle celebrates Heinrich Rudolf Hertz, the German physicist on what would have been his 155th birthday. His experiments with electromagnetic waves led to the creation of the wireless telegraph and the radio. Hertz showed that electricity can be transmitted via electromagnetic waves.

You may wonder why his last name sounds so familiar. That is because Hertz’s name later became the term used for radio and electrical frequencies. Think of hertz (Hz), kilohertz (kHz) and megahertz (MHz). In 1933, long after his death, the Hertz officially became part of the metric system.

Google’s animated doodle is an homage to Hertz’s contributions to physics. The wavy animation, which is in Google’s trademark colors of red, blue, yellow and green, is in recognition of the German physicist’s work with electromagnetic waves. Very fitting!

Great deal on copper plated circuit boards!

copper perf boardReady to do some circuit work? Have any new projects that you need perf boards for? We received a shipment of copper plated circuit boards that are ‘nearly perfect’ – that is to say that they are identical to the regular perf boards that we normally stock except that they were poorly scored and separated by the manufacturer resulting in some unusable mounting holes.

We’re selling them in batches of 10 for $5.00. That’s only $0.50 for each perf board. It’s a great deal and they won’t last at that price.
