Hello Tidak,
Re; your comment Anyhow, I am wondering that American people, who
are so opposite against tax payment, is so strict in this matter...
It is one thing to be against taxes, and there are lots of reasons for
that, it is an entirely different matter to take a chance on going to
How does that work? Seems to me, the trouble (if any)
is for the receiver. Can't imagine that Dutch customs is going
to chase a Chinese seller by the name of Wu Ling, through the
woods of Guadong Qing Qing.
I once had a larger package sent to me, from China. Customs asked
me proof of payment,
Wait...what. That won't work. Needs an inverter or something. I
have some flip-flops that needs a use.
There are various ways to use a flip-flop to do this, depending on what kind of
flip-flops you have. If you have the kind with Q and not-Q outputs, just wire
each output to one of the
I'm using the same circuit but I have these resistor values: R1 = 33k,
R2 = 220k , R3 = 2.2k. I don't remember where I got those values from
originally. I'm sure I just copied them from someone else's schematic.
I guess the exact values are not all that critical, but I just

Hi Mike,
The spinner kit arrived today. Thanks for quick dispatch.
Quite complete kit, however I have to wait for the UF4007's and 1µF 400V
capacitors that are ordered at Mouser by a friends in San Jose
About the modification for the EZ10B rose me the question if the print is
suitable for the

I meant 1ms (one millisecond or 1*10^-3 seconds). Hope that clears it.
The difference was a factor of 1000
Your message implied that you were using 1us (1 microsecond = 1*10^-6)
of wait time.
But as

This is called an astable oscillator by the way.

Of course there are many in this group, including myself, who would
love to have one of those tubes. In all fairness, you should probably
place them on eBay, and then issue a 'shameless plug' (FS:) here. If
there any individuals that should get preference, I believe it would
be those who have
Oh, and off topic; why do I keep getting an error while trying to post

Thank you all for your time.

Thanks! Anyways, is there a place to get nixie tubes, other than ebay?
The prices are crazy there, and my budget doesn't allow that, due to
my age. (I'm 12, got into electronics at 8 or 9.) (IN-18, B-7971, or
B-7037) (Last 2 are super rare, but would be cool.)

If you set your sights a little lower, you'll find that there are still
some affordable nixies out there. Do a search for IN-12.
In my experience, although there are online stores that sell nixies,
most of them are more expensive than ebay. Although with ebay comes a
certain amount of risk, I
Yeah I know about Siemens. Its just that I have this bad habbit
writing ms as mS from college. You are actually the first ones to
notice this and got confused, so I guess I should stop doing that.
No confusion.
Actually Chris was querying your micro- versus milli- second.
No one was really
By going to ebay, you are already at the cheapest place. Can't buy
cheaper than the cheapest.
You may get lucky in a second hand store, but you would have to be very
lucky. Even old electronics store either don't exist, or they already know
of ebay - many basing their prices on ebay
Yeah, built the vellleman kit (ZM1336, appears to be similar to the
ZM1332. Nice tube, but small (13mm))
I found a source of NOS NL807 tubes for $20 each, compared to $250 for
NOS IN-18 tubes. Might resort to those.
(I can get the IN-18s, but no spares, for $240, I get 12 NL807s)
