Just wanted to pass along kudos for a well-made kit and also great documentation. What fun for this amateur electronics enthusiast who misses the old electronics from bygone days...


Just wanted to let you know that my husband absolutely loves the nixy tube clock you made. It is really beautiful.
Thanks again!


Hi Peter,

I absolutely LOVE your creations.... I just saw them for the 1st time today...
I live in a loft, my decor is Speakeasy Chic/Steampunk, I would love to have one of your creations...  I like metal, vintage, wood, things like that, I don't care for that girlie fru fru stuff------ugh!  I just had to write you, your items rock!
Best Regards,


I'm writing to thank you for a superior tube clock kit -- the kit was a pleasure to assemble and works quite nicely.

Thanks for such a great design!


Hi Peter:

I received the clock today and had it built and repackaged to mail to my dad as a gift by the end of the evening.  Thank again for a fun project.  Your design and kit are very well done.  She worked like a charm right away.  Very cool!


I just wanted to let you know that I received my large lichtenburg figure w/stand and I love it.  I have been looking at them for years and I and glad I finally purchased one. 

Thanks and have a great Christmas!!

Take care,


I just received the 6 tube IN-14 clock and it's awesome. I found your website by accident, was fascinated by what I saw and knew that I had to have one. I'll be ordering one for myself soon; this one is going to my father who is a steel plant manager with a background in engineering - he is gonna love it. Thanks again! -Doug


We collected our IN-14 Nixie Clock today and have now got it up and running.  It is an absolutely beautiful and the auto-dim function will be a god send.

Thanks for the prompt service and also the stunning clock now sat on our sideboard.

Karen and Giles W.







Dear Peter,
I just received my Nixie clock. It is absolutely amazing. I have never seen these tubes in real life and they are even cooler than I imagined. The clock is beautifully designed. I will be sure to talk this up with my friends. I hope you have plenty of tube inventory!
Thank you

arrived in perfect working order...absolutely beautiful.

I'll send a larger gush letter later with pictures.

Thank you so much!


Peter, I must say this is absolutely the coolest thing I have ever owned in my life. I got the "naked" version (tubes and PC Board) and it is just fantastic. Thanks very very much and I will certainly be spreading the good word for you.

Hi Peter, I was a bit nervous ordering a clock kit, but just wanted to write and let you know, the assembly went totally smoothly, and I am loving my new clock! The phase transitions the digits go through has to be seen to be believed - it's amazing...

Anyway, I wanted to thank you for offering these amazing clocks and kits. Your instructions were very clear and put me at ease (it's been a while since I've picked up a soldering iron). I'll be telling all kinds of people about your great products!



Peter, the clock arrived promptly and my compliments on your wonderful work,,,It's beautiful! Thank you for the pleasure of doing business with someone who exceeds today's expectations both in service and in quality. Now how do I convince my wife I need ANOTHER one??!!

Bill B.

Received my clock today and I just wanted to say that it's even better than I expected! Thank you very much!


I received my clock today as a gift from close friends.  I thought I should share with you my thank you email, feel free to use any or all of it as a testimonial.  I am so thrilled, I ordered another one already, for a friend who came over tonight & fell in love with it.  You are a true craftsman.

Hi Peter,
Just a wee e mail to say thank you so much for all your help with the clock, my boyfriend is absolutely delighted with the it and he asked me to pass on his thanks too, (clear instructions, excellent packaging and very high quality parts and great fun to assemble).
best wishes and Happy Easter
Lisa :)

"I am overwhelmed.  This is the most wonderful, beautiful present I could ever have imagined.  It's like you downloaded my subconscious mind and filtered through the mess to find one true desire.  And there I was, the guy that thought he didn't need or want anything.

Anyway, these pictures certainly don't do it justice, but I've been staring at it hypnotically for a while and I thought I should immortalize it in photo form in case I wake up and it was all a golden dream.  It's actually much more intricately programmable that one might imagine at first glance.  I've set it to dim during the wee hours, and reawaken in the morning.  I'm kind of torn, but it most probably will come with me to the studio, since that's where I spend most of my waking hours. Plus of course I want to show it off.

So... thank you thank you thank you.  This was truly a wonderful surprise and an amazingly generous gift.  I hope you will get one for yourselves, if you haven't already, because I don't think you'll be able to live without one once you've seen it in person."

Hi Peter
The clock arrived to me in NZ in perfect condition.
It looks real cool!
Haven't had a chance to set it up but I'll do that this weekend.
But I got a 500ma PSU, fired it up and it works just fine!
Cheers again

Hello Peter,

I received my clock last week and just love it. It appropriately and proudly sits next to my tube hi-fi gear.  Your quality clock already getting noticed by visitors !!  Sincerely, Tom S

Peter :

Received the clock today.  It's beautiful.  You did a good job.  This is my first Nixie clock and I hope to collect a few more.  May be a good Christmas present to someone that appreciates it.


Hi Peter,

Just wanted to let you know the clock works fine. I was able to complete it in about three hours following your well documented instructions. Your kit reminds me of the kits I use to get from Heathkit, very professionally done and easy to assemble. Its really neat looking and functional!

Thanks again,
John W.

Peter - the two tube clocks arrived yesterday in perfect order - great packaging!

I set mine up immediately - no problem whatsoever - it looks wonderful in my office.

And the other went off to my stockbroker to add to his collection.  He gushes over it.

Well done - you deserve kudos and an A plus!

Cheers from Vancouver.


Just wanted to fire a note to let you know the clock arrived well wrapped and in perfect condition.  I'm extremely impressed by the quality of the clock, and everyone I've shown it to -- techies and non-techies alike -- loves it.  Keep up the great work!


Mr. Jensen;

I just wanted to let you know that I received my tube clock yesterday via priority mail. Thank you for such fast service! I set it in my workplace this morning and it has already elicited a number of “Oh, wow!” comments. Several engineers have asked where I got it and where they could obtain one. I’ll be sure to send them to your web site.

I first saw your nixie tube clocks at the Dayton Hamvention in 2006. I decided then that I had to have one, eventually. Thanks you for making such a wonderful product! 73,

Dwayne S.


Just received my clock and it's WONDERFUL.

I remember back when I was a kid (in the mid 70's) and I had a military surplus frequency counter that was nixie tube powered.

That was a long time ago.

I'm going to enjoy this very much!

Hi, just a quick line to let you know I really love my Nixie clock. The kit was well documented, it worked first time, and watching time go by has never been this much fun! - Matthijs

The clock arrived yesterday (July 5) in perfect condition.
My husband loves his nixie clock anniversary present though I think I like it even more. It's a unique combination of functional art and mid-century history.
Thank you, Peter.

I received your kit several days ago and immediately opened it. What I found astounded me; the kit was incredibly well organized, all parts were in the inventory and the tubes securely packaged. The board and artwork are first rate, the instructions clear and concise! And a personal letter from the Maker.

I placed the kit aside and came back to it earlier this evening and began to assemble it. I fully expected to run into some kind of problem (major/minor, your choice) and am very happy to report that the assembly went very smoothly. Your instructions for soldering SMD parts worked exactly as described.

More importantly as soon as power was applied to the clock it began to count upward! Ahhh the sweet smell (or lack thereof) success hung heavy in the air!

Most impressed was my 20 year old son that has been introduced to some seriously ‘old school’ technology. He will be getting one of these clocks for Christmas.

If I might make one suggestion: include a small length of plastic tubing that can be cut and placed over the neon light leads. This can act as a spacer / support for the relatively fragile leads and can help prevent short circuits in case the neon’s get twisted up.

I’m looking forward to your next kit!

Best regards,

Chris S.

Good job with the clock, it looks great.

All the best,
Simon L

Hello Mr Jensen.  I just wanted to let you know the kit made it and everything looks fantastic.  You even included solder!  I'm very much looking forward to putting it together.  It's for my roommate... I think she's going to love it!

Finished the kit two minutes ago, plugged it in, and works perfectly. What a fun kit for us old timers. As a journalist for UPI, our photo department had a similar timer on their electronic transmission board. I have loved the Nixie tubes ever since. Just wanted to let you know I am delighted.


Hi Peter,

Just wanted to say that I received the desk clock and it works beautifully!! I thank you very much for it and appreciate all the questions you answered for me before the purchase.

I have sent positive feedback on Ebay for you.

Thank You Very Much,
Brian H


I just wanted to write to let you know how pleased I am with the nixie desk clock kit that I purchased from you last week after reading about them in the latest issue of "Make" magazine.  The delivery was prompt, the kit complete, and the instructions were exceptionally clear and thorough.  It showed up last night on my doorstep, and I had a great time this morning putting it all together.  The assembled clock looks fabulous and works flawlessly!!
I'll definitely be giving out at least one or two kits as Christmas gifts this year.

Thank you!
Kevin J

This is a wonderfully anachronistic (pun intended) visit back to the hi-tech of my earliest recollections.  Since I am a guitarist and play mostly through tube amplifiers (old and new), this is perfect for my home studio!

Hi Peter,

Your little Nixe type clock really works great.  I always wanted one since I saw my first non-military digital clock in a furniture store in Bremen, Germany in 1966.  It was a work of art or maybe even a piece of furniture! It used smaller tubes to indicate the seconds and it was built into a fancy wooden box.  I don't remember what it cost but I remember it was too much to spend from what Uncle Sam was paying me back then.  Anyway I told myself that it probably wouldn't have worked on our 60 Hz line frequency if I brought it back to the states. So thanks to you, I finally have something I wanted for 40 years!

I have to tell you that at first I was a bit unhappy with the weird (Russian?) #5 but after watching it for a few hours I got used to it, and I now think it gives the clock some character!  It's telling you that it's not an LED or LCD display your looking at!

Currently, the clock is living on top of my computer's CPU in my computer/Ham Radio room.  I also happy to see that it doesn't seem to add too much to the RF noise around my Ham Shack so it looks like your clock won't cause any problems with the FCC!

Thanks again,

John M.

So I just received the clock today, and this is one the coolest things
I have ever seen, I'm very pleased with it and proud to display it, I
wanted to thank you for the extremely fast shipping and for the great
clock, and when people ask where I got it I will refer them to your
website, once again thank you very much have a great day...

Hello Mr. Jensen,

Just wanted to let you know I received the Nixie and am positively thrilled with it!  My husband has already asked if I would give it to him.  Guess I'll be ordering another one later in the year when his birthday rolls around.  Thanks for the superb transaction.  It was my pleasure to leave positive feedback for you at Ebay.

Best regards,
Rejeana M.

Dear Peter

I just purchased your black powder nixie clock. It
is wonderful and it is really nice to know that it was
made by someone who truly values his craft. I did
want to ask if you plan to see replacement nixie tubes
or recommend a supplier. I'd like to pick up a set
just to be sure for the future.

Thank you again for your great service and product.
I promise to spread the word about your site.


Hi Peter,   Thought I'd give you an update on my new clock you sent…

Got it today after work.  Plugged it in and set the time…

Thank you for a great clock,  its just fantastic…  how long does
It take before you stop staring at it..  ;-)

Just an excellent implementation of " old and new " technologies



I received your clock kit today.  It was very easy; it only took a couple of hours, and worked great.  The only problem is that I think I need stronger bifocals after mounting the high voltage driverJ.  I do think the display is better without one of the 33K resistor, maybe in a future version of the clock you can make the brightness variable.

You have me hooked on nixie clocks, now I will have to find more kits to build.

Thanks for putting out a great kit, I really enjoyed it.  The personal letter with the kit was a nice touch also.
