Hey all,

 

My son wants to build this clock for his play room:

 

https://www.banggood.com/DIY-NB-...

 

THing is, I have been reading that most of the time the clocks come with a non-working tube or two and the Banggood response it to do a partial refund and on to the next sucker.

 

I have been looking around and I have found a few possible 'spares':

https://www.amazon.com/Retro-Seg...

 

https://www.ebay.com/itm/6x-IV-1...

 

https://www.ebay.com/itm/IV-11-2...

 

 

My question to the community, is has anyone ever been able to order the tubes, and from where if you have?

 

THis could be a cool project, but the disappoint factor is medium to high unless I have a couple backups.

 

Thanks

JIm

Hi Jim,

 

I've ordered a few Nixies off eBay and they were good.  I think it was a US seller who also had a driver board for them though; don't remember who it was.  I do think people have good luck ordering them from Russia though as they have a overstock of them.

 

Good luck!!

I do not have much trust in Banggood.

I've heared some stories of negative reviews simply being erased or not placed at all.

 

If you buy through Ebay or Aliexpress however, the placement of feedback is not in the hands of the seller and sellers are more inclined to resolve problems, at least upto the deadline of a transaction. After that they often do not even bother to respond.

At least Ali, but maybe also Ebay work in a way that they keep the money of the transaction on hold as long as you have not received your product or conflicts are ongoing. This is a big motivator for sellers to make their customers happy.

I agree that banggood is far from the most reliable place to purchase things.  But their prices on some stuff is worth the risk sometimes.

 

I will look at your other options

Looks cool.

The link above also leads to these, have a nifty 8 digit VFD display... wonder if you can update the MCU code  ?

 

https://www.aliexpress.com/item/...

and there are 4 digit nixie ones too..

I see Adafruit had a version, but no longer available..

Well, guess I'll stand up for Banggood Electronics.

 

I've purchased several of the little ARM based toy O'scope kits, lots of Nano's (clones), some Arduino type Shields of various types, and most recently a bunch of 8, 5, and single channel IR sensors for a little line following robot.

I've purchased some other items, PCB stand-offs, prototyping boards, scope probes, some mini and full sized breadboards, and some of those pre-fabbed M-to-M breadboard wires, digital LEDs, piezo's, PCB switches, etc.

 

I've never had any problems.

I do not have much trust in Banggood.

A few months ago a got a "Netflix" box from them, it started working great but then on some programs the video would break up, at times it would fix itself up but then break up again.

 

The box is only used during school holidays so that the grandchildren can watch their shows in the rumpus room instead of making a mess in other parts of the house. Unfortunately the problem seems to happen more during those programs. At times I would switch to U-tube and it would work OK there.

 

It seems to me that the box is not caching the video fast enough and just to be sure I had a good Internet link I run a fixed wire to the box instead of using Wi-Fi, the problem persisted and I complained to Banggood. After messing around around with their suggestions to fix it (and I knew that would not work) they are sending me a new box, see how that goes.

 

I've had other things falling apart and got free replacements so I'm getting very cautious buying stuff from them.

I am debating on ordering panels of WS2128 LED's for a project I am debating taking on.  Looking for alternate suppliers.

Jim, those fluorescent 7-segment displays pop fairly regularly on the bay; there are some there now on the UK site, from Russia, at a tenner for a dozen (though I think those may be a smaller size).

 

A seller who can be trusted, if he has them in stock, is Jan: http://www.die-wuestens.de/einde... (scroll down).

 

Personally, I prefer nixies but the type I like is getting to be made from unobtanium...

I lie nixies as well, but for a ten year old the voltage is a tad high for him to play with.

The  fluorescent 7-segment displays still have significant voltages ?

 

Adafruit says this, on their kit  :

" Before you start...
This kit generates a high voltage - 40V to 70VDC. Only persons who are competent at electronics assembly and understand the dangers of high voltages may attempt to assemble this kit! Safe assembly and operation of this kit is the users responsibility.

This information is provided 'as is'. No responsibility is accepted for any damage, injury or death as a result of assembling this kit or using the information therein."

Yes, I know that and I will be watching this carefully.  True Nixies did operate at a higher voltage level.

Another safer alternative would be to use a lower cost colour LCD display, and use nixie-image-fonts ? (older purists may be having heart attacks here.. ;)  )

eg  https://nextion.itead.cc/nextion-shop/  looks like a small MCU could manage a clock, with a suitable nixie or fluorescent image set in their flash ?

That takes the fun, and look away from the project for sure.

 

I'll stick with the tubes and see how it goes.  My son has been pretty good with not zapping himself with a C.O.P. snowball expeller.  And the COP generates Engine Ignition voltages so I think we should be ok with this.

As far as I know the power / current behind these display drivers is very unlikely to be very dangerous. It might give you a good scare and hurt a bit, but that's about it.

Just don't go charging big capacitors with those voltages and push them to your chest on a hot and sweaty day.

 

According to Wikipedia the orange Nixies need a few mA @ 170V 

https://en.wikipedia.org/wiki/Nixie_tube

 

Not too long ago I accidentally shorted a high quality low ESR 47mF 100V elco in an audio amplifier.

Loud bang, big sparks and another DDM probe ripe for the garbage bin and a dent in my pride, but no further damage.

It does make you think about wearing some eye protection for at least some of the electronics projects though.
