Retrotechtacular: First laser transmitter built 50 years ago

helium-neon-laser-transmitter

Most of the time we feature hokey film footage in our Retrotechtacular series, but we think this hack is as cool today as it was fifty years ago. [Clint] wrote in to tell us about Operation Red Line. It was an experiment performed May 3rd and 4th, 1963, which means the 50th anniversary just passed a few weeks ago. … Read the rest

A clock made out of some very weird tubes

If you’re like [Richard], you’ve got a few really rare components lying around. Maybe it’s a very weird micro or a really tiny CRT, but eventually you’ve got to build something with these parts. When [Richard] decided to put some ITS1A neon display tubes to use, he fell back to the old standby – a really awesome clock.

Neon binary clock

[Josiah] said ‘no’ to LEDs and instead used blue-phosphor neon lamps to build this binary clock. The ATmega328 inside uses three 8-bit shift registers to control the display. Each lamp needs a high-voltage NPN transistor in order to switch on the 150V necessary for proper illumination. A simple circuit was used to pull a 60 Hz clock signal out … Read the rest

A bright way to cycle

Want to be visible when cycling at night? [Neon Dean] came up with this possible solution, which he cruised on at Nuit Blanche. Its a bicycle with neon lights mounted on every surface possible. [Dean], who gave a similar treatment to his car, explained how it worked. All of the tubes take their power from a 12VDC battery he Read the rest

Toronto embraces 4-letter words

This year was not the first in which the City Hall of Toronto was lit up in a unique way. However, it was the first time that the government building was used to project 4-letter words. Brainchild of [D.A. Therrien], the 4LWM represents something that he imagined for a long time. [Therrien] built the huge sign in Scottsdale, Arizona, … Read the rest

Nixie Plasma ball

This one came out over a year ago and we missed it. [Daqq] has made a plasma ball out of a nixie tube.  All that was required was the transformer from a cold cathode meant for computers and a nixie tube. He did have to do a tiny bit of modification to the power supply, which you can see … Read the rest

Neon light Christmas tree

gpugh_topshoptree081

Everyone always complains about the Christmas season coming earlier and earlier, but we think when we can have Christmas trees like the one pictured above, it’s not such a bad thing. Created by English fashion designer [Gareth Pugh], the tree features sixty white neon tubes, and is supported by a freestanding metal rod. It reminds us of the light … Read the rest
