Quick look at IRIG-B time signal - getting 1 pulse per second 

Mate please please keep these videos coming regular schedule as much as possible. You are great. Greatings from Turkey!

I really like the detail you go into with the technical problems you are facing and how you approach solving them. Keep up the good work!

OMG - seriously amigo, what kind of godamm genius are you??? I am in total shock!!

Dalibor, I have spent too many hours calibrating radio transmitters Ultra high stability oscillators to 1 part per billion. The time standard we used for that was a Ball Rubidium standard. For some lesser accuracy required equipment, we did use a GPS receiver with a 1pps output. One thing I learned and I can only speak to the particular GPS receiver we used. That without a gps input, things would eventually get a bit drifty if it didn’t see a bird for a while. I have been out of that part of the industry for 10 years now, so maybe what you have is stable without seeing satellites on startup. Just saying the output may be a little more stable with a GPS lock. My other thought would be playing with the scope triggering. Being a tech on the other side of the globe, speculating on what you are doing, without a lot more information is irresponsible on my part. So forgive me if what I mentioned is irrelevant. I can’t wait to see your solution. Please make sure you let us know how you solved the problem.

14?!? Whoa mama, that's a lot of Nixie tubes. Also, digging the video editing. :)

Splurging on a brand new RGA! Must be an interesting project :)

Zdravím Dalibore, co dodat? Vy jste nezmar a věřím že to vyřešíte. Přeju hodně úspěchů a už se těším na další videa.

Hi, if I look at the datasheet at 3:09, the "sinewaves" all start with a rising (positive) half-sine. In your oscilloscope-plots, 10:30, the first peak is *negative*. It leads me to think that the polarity of your isolation-transformer is inverted, so it is not a phase-shift, but rather a phase- _reversal_ . Perhaps swapping the polarity helps?

Where do you get the getter materials from? I want to try making triodes to learn how vacuum tube technology works.

Hi Dalibor, I really enjoy these videos, thanks for making them. Are you editing these videos yourself?

Bro I went to meet you. I am so inspired by you.

Awesome video!

Great video, I like the format! A small suggestion - maybe get help of a professional videographer and make an intro and outtro for channel videos? PS I was wondering - what is your educational background and what's your other business? Thanks.

Nepripada mi to az tak zlozite. V com bol vlastne cely problem - v tych 10us ze je to prilis malo na procesorove spracovanie?

The signal source is the Brandywine Communications GPS4, Time and Frequency Standard. www.brandywinecomm.com/products/42-products/commercial-gps-synchronized-clocks/83-gps-4-time-and-frequency-standard This product (2005) has been discontinued by Brandywine, replaced by a GPSDO product.

Hello there… I am looking to extract the 1 pod signal from IRIG B… do you have any source code for Arduino that might help. Thanks.

SWhat type of interface are you using? Like rs-485, re-232 etc?

Poptejte si v Gatemě projektový prototypový multipanel - pokud se vlezete celou sestavou desek s vlastní panelizací do jejich standartního technologického přířezu, je to mnohem levnější než běžný pool servis, ale s nepokovenou frézou vč. obrysů desek v ceně.
