Reliability of our nixie tubes – vacuum tightness

Customers often ask questions related to lifespan and reliability of our nixie tubes. We recently made a tube with serial number #3000, I think we now have representative sample of tubes to make some nice statistics. In following months, I will write several articles covering all the problematics.

Mid 2017 update

Recent 6 months were pretty busy, we now make much faster progress in development of our little nixie tube factory than anytime ever.

This blogpost is a summary of our successes and also problems we face to. Let’s take a look what’s been going on here:

Zen Nixie Clock

The Zen Nixie Clock is what has been making us really busy. Since summer 2016, we’ve shipped over 100 clocks and have received great feedback from customers. Apart from nixie tubes themselves, customers like minimalistic design and also electronic features of our clock (internet connectivity with automatic time synchronization, clock settings accessible from website, easy online update with new firmware etc..) and level of craftmanship. The Zen clock is now our main product and project which pays the bills.

Zen clock was also a complex lesson regarding to understanding of who is our customer, motivation to get the clock and most important – customer’s expectations! All these information are invaluable for our future creations.

We now ship 1-4 clocks every week, in a bit unpredictable pace. With 18 suppliers involved (just the clock, not counting the tubes!), issues (and delays) appears regularly.

We now have 34 orders for Zen clocks. We were shipping at lower pace than orders were coming, so I decided to stop taking new orders to catch up. I expect to finish all these orders in 3 months, then I would like to open orders again – stay tuned (http://www.daliborfarny.com/newsletter/)!

2016: Year in review

Year 2017 is here, right time to review year 2016. Year 2016 was about transformation from one-man-show to small company. And because business is about numbers, I decided I will share them with you. Maybe business people among you will have some notes to my decisions 😉

One year ago, I set myself a goal to arrange things in the company so that I can hire an employee to help me with the manual routine works on nixie tubes. I was working alone, with Karel, a pensioner, for small ad-hoc jobs. My wife Eva was helping me with administrative tasks (accounting, all the bureaucracy, etc..). And I urgently needed a help. This new employee should have been someone  who would step by step learn all the processes of cleaning and assembly of inner tube parts and would become a regular employee in long term perspective. During first months of 2016, we had approximately $5.000 monthly stable turnover, IMHO right time to hire first employee.


After some time, we found a skillful lady (Monika) for half-time job, she had experience with soldering and similar jobs. I offered a bit higher salary than common for manual job of this character. She was first employee and the last thing I would need is to lose her after training because someone else offered 20% more (economy is growing fast here, unemployment very low). In two months, she learned lot of operations from the nixie tube manufacture. The beginnings were tough, I was learning how to train, prepare the work, check the results and what to do when you run out of parts for assembly 😉 After few months, Monika was eventually able to work almost independently on me. I finally found this whole process worth all the struggle, I could start with new project – Zen Nixie Clock.

Zen Nixie clock – update #2

New updates regarding the Zen Nixie clock are here!

Aluminum parts surface finish

I just received first small batch of tube bases from Adruu, Netherlands based company specialised in surface treatments of aluminum parts. The results is amazing – uniform surface, very nice satin texture. The bases are bead blasted first, then bright dipped and eventually anodized to final color. Special thanks to Adruu’s commercial director Joran van Bussel for very very kind attitude in whole process of this order!

The bases will be available in Silver, Champagne gold and black finish. Case aluminum stand, nixie tube bases and colon tube bases will have the same matching finish.

The stand is made of aluminum, it sits on 8mm tall rubber feet. The cover is made of glass and protects the tubes against possible damage and also keep away dust.Zen nixie clock with case

The blog is back!

It has been almost two years since my last post on the blog. In 2014, I decided to switch to Facebook and add only short posts with photos. Facebook is great platform for sharing short posts and interact with people, but I found I miss writing more detailed posts. We are now working on several interesting projects which deserves to be described more in details, so I decided to revive the blog. Of course, I will not make posts daily, but it will definitely be more frequently than once per year 😉 Every post will be share on Facebook, so if you follow us on FB, you will not miss anything.
