Q: How can I set my clock so it will switch automatically between date and time?

A: Press button 1 five times to get to the Time/Mode, which will display each for 10 seconds.
For clarification: When all tubes are off, it is in "Blank/Rs232 mode". Then if you push button 1 once, the clock will be switched to "Time Mode". Push again to set it to "Alarm 1 Mode", then "Alarm 2 Mode", then "Date Mode" and finally "Time/Date mode".


Q: I heard the smaller nixie clocks do not have a long life span, is this true?

A: I have several of these clocks that are still up and running after years of use. Nothing will last forever, but with the right construction the smaller clocks do have a good life span.

 

Q: Can my clock run on car battery power for use in a vehicle?

A: No, unfortunately these clocks were not designed to be used on any sort of battery.

 

Q: What are some software suggestions for my IN-12 Nixie Counter to display data from my PC?

A: Any program which can send ASCII symbols to a serial com port. A simple terminal program such as Windows Hyper Terminal works well for that. Also there is a script for Linux which sends data to the clock every time your web server gets a page hit, if this is what you are looking for.

 

Q: What is the proper voltage I should use for my clock/device?

A: IN-12 clock         - power adapter 9v, min 300mA
   IN-12 clock/counter - power adapter 9v, min 250mA
   IN-18 clock         - power adapter 12v, min 250mA
   IN-17 clock         - power adapter 9v,  min 250mA
   IV-18 clock         - power adapter 9v, min 150mA
   IN-18 digital clock - power adapter 9v or 12v, min 150mA

 

Q: Can I get an upgrade on my clocks PIC with new firmware?

A: Yes, it is possible to get an upgrade. If you have a 16F882 microcontroller, we have to upgrade it to 16F883, which has more memory. It will cost £10. If your clock already has 16F883, the software upgrade is free. However, the delivery charge is not exempt on either.

 

Q: How long will shipping take?

A: Shipping time always varies. However as a guideline these are the average shipping times:

   UK:        1-2 days

   Europe:    3-5 days

   Australia: 1-2 weeks

   Japan:     1-2 weeks

   Hong Kong:     5-7 days

   USA: 1-2 weeks

 

 

Q: Will my clock come assembled and ready?

A: Yes, when you receive the clock it will be fully functional. However, there are 2 things you should have on your own, whether you are an international customer or not:

  •    wall plug 9v DC regulated power adaptor
  •    case/enclosure for the clock

 

Q: Are the tubes on the clock removable and/or replaceable?

A: They are socketed, not soldered on, so very easy to replace if needed.


Q: Will my nixie tube be hazardously hot if left on?

A: If running constantly the tube will only be slightly warm so there's no hazard to touch it or for it to be placed near other objects. However it is not advised to be placed by open fire or heaters.

 

Q: Is it possible to replace the tubes from the in-18 model with smaller ones? And is it possible to replace the tubes from the in-12 model with upstanding ones?


A: Yes, it is possible to replace tubes with smaller one, but you have to wire your tubes manually, as your tube pins layout and size will be different from IN-18 tube
For IN-12 clock the answer is the same, you have to manually wire and solder new tubes, as this clock has been designed for IN-12 tubes only.
 


Q: Do you supply any of the tube clocks as a self assembly kit?

A: Yes, almost all my clocks are available in self assembly kit.
The kit price is £5-7 less than assembled clock.

 

Q: Can you tell me how many volts these thing need to light. Do they need any sort of inverter Etc to work.
 
A: Nixies use high voltage. They need around 150-170 volts to strike, and then maintain around 120-140 volts or so across the tube while running.
I am selling the switch mode power supply module to provide around 180V DC to drive the nixies.
Please search for the ebay item number: 260385003973


 
Q: Some of the Mullard nixies need 250V DC. Can your convertors output this with a resistor swap?

A: It could run up to 300V , but you need to change resistor and output filter capacitor, as it's currently 1uF x 250V.
Plus you have to supply minimum 12V DC to this power module, if you need output voltages higher than 200V.
 



Q: You mention custom made Clocks, What can You make Me with these Tube's, and how much am I looking at if You have the Time? I was actually thinking of getting some IN-1's, and asking about this, but since You have these and they're pretty close to size, I figured just to go with these.

A:
Custom design usually cost 200-500 USD depends on complexity of the device.
IN-4 clock is in my future designs list, but I do not know yet, when I'll start it.
If you need just one IN-4 clock, I am afraid you have to wait when it's done or try to find it somewhere else.
If you would like to buy several IN-4 clocks, I can put this design on my priority list and it would not cost you any extra money, just normal clock price, as I sell it on my web site.
I have no plan to design clock on IN-1 tubes.

 

Q: I need a power supply in the range of 140 to 150 Volts DC approx 5mA for a IN-13 nixie. Can I tweak the output voltage with this module? Is this module regulated? Which controller have you used?
 
A: Yes, this module is regulated and has stable output voltage.
If you need 140-150 volts, it's easy and you need to replace just one resistor. 
You can get up to 15mA output on 150V, so 5mA is  not a problem at all.

 

Q: I just purchased one of your awesome IN-12 Nixie clocks and I have a question about adding external buttons--I assume I use "momentary on" push buttons, is that correct?

A: Yes, you have to use momentary on buttons like on keyboard. I use Tactile Switch, which is widely available to buy. If you install buttons more than 5-7 cm away from PCB, I would recommend you to use screened/shielded cable.

 

Q: I recently bought your clock kit via ebay, and it is running OK, But what can I adjust with the trim cap, or how should it bet set?

A: To setup clock just find User Manual on my web site, DO NOT adjust trim capacitor! As it's just used to calibrate your clock for best accuracy.

 

Q: I was wondering if this nixie clock comes with a case to hold the pcb board. I really like this one but I fear that dust would get on the board and cause the clock to malfunction over the years.

A: This clock does not come with a case yet, and I am working on it, but not sure when it will be available.
I have a few my clocks running without cases for years and it works fine, so dust does not affect clock functionality at all, unless you going to use it in some very dusty and wet conditions ( like workshops, garages and etc.), but I do not recommend it. Just use soft brush once per month/year and it will be OK...


Q: But how do you tell the time with just 1 digit to know the hh/mm ect and is it really very accurate?
 
A: Please have a look at short movie, where can see how clock displays 4 digits time on one digit display.
Link to watch short movie:
http://www.kosbo.com/img/in4clock1d/time.mpg
I use crystal (not 50/60Hz mains frequency as my competitors do)  for clock generator, plus I calibrate every clock I sell, so accuracy is good.

 

Q: I put the clock together but it didn't work I did not see a display,
I want to know do i have to program the micro-controller, if the maxim 6891 is bad what other chip could i used as substitute or just give me an idea of what the possible problems might be why this clock is not working.

A: This clock kit has been assembled lots of time and I have never had faulty components in kit yet. Microcontroller has been programmed, so you do not need reprogram it again.
In most cases the fault come from wrong assembling - wrong polarity on diodes and capacitors, wrong chips position, some solder pads were not soldered, or there is shortcut somewhere between close pads. Please double check it all. It is difficult to help you as I have little information from you as you only  said it does not work and that's it.  I assume you have voltmeter and understand  circuit diagram, the next step after checking what I said above, is to measure voltages on the circuit in accordance to circuit diagram. Please let me know what voltage you have got in your clock, so we can think of what we can do next.

 

Q: Do I need a computer to let the clock work?

A: No, you do not need computer to keep clock running. Connection to PC is just extra feature allowing your to display some data from PC on the clock display.

 

Q: Is it possible to let the digits fade in/out?

A: Sorry, digits are not fading in/out in this sw release, but this feature in the future plan.

 

Q: Do you have power supply's for your clocks?

A: I usually do USA, UK, European Power adapters.

 

Q: Approximately how long they can be without wall current, without losing the time?

A: Clock will run on backup battery for about 2 days, it will keep time, but will not display it.

 

Q: Is it possible not to put the seconds tubes in?

A: You can remove seconds tubes, but it's not recommended as in date display mode and in setup mode all 6 digits are used.

 

Q: Would a magnetic field affect the clock?

A: Magnetic field can affect clock, but it depends on how strong and what direction this field is applied.

 

Q: Does this clock come with any housing and USA power adapter? Are IN18 nixie tubes new?
 
A: Clock is selling as a kit, it fully operational, but it does not have enclosure nor power adapter. IN-18 tubes are new (never been used), but from old stock (were stored somewhere in stocks for years). Nixie tubes are not in manufacture any more.
  
Q: I'm thinking of making a case for the electronics with the "tubes" protruding through the top, would this require some cooling slots to the rear and would it require a clear cover of some type over the "tubes" for protection?
 
A: A few holes in the bottom plate of your clock case and small gaps between tubes and case will be enough for electronics cooling.
Tubes are made of glass, so it's quite easy to break, but depends on when and how you are going to use this clock, you might or might not need extra protection for tubes.
 

Q: Can the tubes be replaced if they fail?

A: IV-11 tube are soldered on the board, so it is possible to replace, but not easy.

 

Q: One of your clocks is a lot more expensive than other clocks is there difference in quality?

A: More expensive Nixie clock is IN-18 Clock. The quality of my clocks are always on the top level, but this clock costs much more because IN-18 tubes are very demanded, beautiful, rare and  expensive...
