60's Scratch Build Nostalgia Neon Blinky Tree!!!
🕑 Added 2020-12-31 23:18:30 +0000 UTCAnother retro build project that was popular back in the 1960's because you could build it completely with cheap Cold War surplus parts - and in keeping this tradition I used ONLY stuff that I had in stock in my bins to build this relaxation oscillator tree. I packed this video with all the info you could want, (and more) and hopefully I answer all the questions you'd want to ask... so Enjoy!

beautiful solder work, first rate stuff and the wire angles are cool too
You are amazing Fran! 👍 The blinking lights reminds me of the lights blinking on the robot dome head in the TV show Lost In Space🛸.
Aaah, lovely - wondered what that thing was in the other video :)
Great Joe
Oh man, there's probably a huge number of ways to mess with this circuit. I'm guessing that for us Euro folk, we might have to put in dropper capacitor in series before the diodes, since 250 rectified goes up to 350. I also wonder what'd happen if this circuit had no filter caps for the supply rails, if that'd make the blinking slow down a bit.

That's beautiful! I would love something like that, with a slower blink rate. Very nice Fran. 😃
A wonderful build Fran. Happy New Year!

Thanks Fran, what a great little project, happy New Year.

Our line voltage is 245 volts here in the UK so roughly 346 volts dc- scary thought. but a fantastic build - thanks Fran and All the best wishes for the new year.

The craftsmanship of how you bent every lead of every component so perfectly blows me away! And such clean soldering too! Techno-art using vintage components. I never would have thought of that. You know, of course, you now have to assemble your own vacuum tubes! I'm sure you can figure out glass blowing and maybe you can make your own display tube where others left off? Great creativity to finish off this horrible year! 2021 will be "The Year of Fran"! Keep feeding us your great investigations AND art projects!

Nice "old-school" build Fran. Loved the glass dome to display it, too. Thanks for sharing.

Wow. Saving the best video of the year for last! Engineers are taught to calculate everything to the last digit, and then simulate it, before starting the build. Doing this kind of "whatever" construction really shows how art, science and whim can come together in creative, powerful (and fun!) ways. Here's to FranLab in 2021!

Cool!

Build and learn! For a neon tree I yearn!

I love it. A piece of functioning electronic art built from spare components, what better way to start a new year?
