I am wanting to try my hand at making my first NIXIE TUBE type project.
I do not want to buy a clock kit or anything... I have a few ideas for a project.. but want to get/understand the essentials..
Im thinking for my first project..
I'll use 2 nixie tubes... not sure the specific model, as there are many on Ebay.. but some smaller sized tubes x 2.
these will be attached atop a wooden based.. where the arduino standalone circuit will be housed.
Id like to attach a simple temperature sensor.. and give the arduino the sensor output... and have it power/change the display of the nixie tubes to reflect the temp. (rounded to nearest whole number is fine)
I have never used a Nixie Tube before.. nor have I messed with such high voltage project (a bit scary..but non-the-less Im moving forward with it)
Form what I gather.. I'll need
tubes x 2 driver chip(s) power supply Arduino public software library (I guess this is based on the driver chip of choice?) enclosure/housing..etc
So to try and research things a bit.. here are the components I have found & plan on using.. (based on feedback form here of course) :)
1.) The NIXIE TUBES: (or similar) http://www.ebay.com/itm/NIXIE-TUBE-IN-16-4-pieces-Ukraine-Used-/310397567340?pt=LH_DefaultDomain_0&hash=item484523016c
2.) POWER SUPPLY: (not sure what one is best..or how many nixie tubes I can drive with each one? just one? multiple? what decides that.. the output pads available?..or can multiple tubes share an output if enough current is there to support more tubes being used?) a.) http://www.ebay.com/itm/260957785804?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 ---this one looks ot have 2 180v+ outputs.. (as well as 12v and 5v...can run Aruidno off it too then?) not sure WHY the two outputs.. means only 2 tubes can be used then? Also has a barrel jack.. which Im sure will be used with walwart..but really not a big concern... can solder on my own for correct placement in the wooden base..etc
b.) http://www.ebay.com/itm/320831452311?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 --- this is small.. love the size... not sure how many tubes I can run off it though? (min input V is 2v?? can I run this one off the Arduino then? no wall-wart.. using the same 7.4Li-Ion pack as Arduino?)
c.) http://www.ebay.com/itm/320831453118?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 same as above I think..but breadboard friendly??
d.) http://www.ebay.com/itm/260921320989?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 --- just another version I found while surfing around..
3.) DRIVER CHIPS: (not sure what ones to pick..or if it makes a difference.. but since I'll be replying on a public library..unless its a simple as turning on/off a digital pin or something..never used a BCD to Decimal driver before....... I'll need to make sure whatever library people use,.. matches the chip(s) I get/use.. is it 1 chip per nixie tube?)
these seem to be original/authentic Russian 74141 chips? not sure if these are better?
b.) http://www.ebay.com/itm/260480090130?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 these are the 'replacement' 74141 chips.. the K155ID1 chips...
4.) Arduino.. I'll be using an Arduino Duemilanove 2009 board for testing/prototyping my circuit/project.. then move to some other tiny, DIY, minimal/standalone Arduino circuit to fit the footprint of the base the tubes will sit on.
-- not sure if a BCD to Decimal driver chip is easy to use?.. Or if there is some sort of public library available for use, specific to Nixie Tube projects.. or just a library that one uses to talk/communicate to BCD to Decimal driver type chips?
Id like to hear you feedback, experiences.. and if my potential stuff above Im planning on buying is what is needed?
For bonus points or fun discussion/learning...
What are the differences in driving/running a VFD type of tube vs. a nixie type tube?
(was wanting to make a calendar/date stamp out of this one)
Second bonus question: http://www.ebay.com/itm/150655466241?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
dig it.. looks nice.. but how does it 'work'? How many leads come otu of it? how do you determine the size/length/height of the bar graph? more voltage to it? analog? (doubtful)
(would be nice to have this as a standalone or coupled with the temp project I want to do above.. just for more of a visual)
