Re: [neonixie-l] 74141 decimal place

[John Snow]

Right now, nothing, but I like wire up or breakout connections for later 
use.

It's less forward-planning and more not getting in my own way later.

Re: [neonixie-l] 74141 decimal place

[David Forbes]

The 74141 was created back in the Switch Age, when a rotary switch was used
to select which digit had the point.
What do you want to use the decimal point for?

[neonixie-l] Re: 74141 decimal place

[John Snow]

Great, that's what I thought it meant.

Now I'm tempted to skip having a decimal point, and avoid the extra hassle 
of an additional 74141 & 74HC595 to drive it.

[neonixie-l] Re: ZM1350 Footprint

[Paul Andrews]

I hadn't actually read the datasheet until now. I didn't realize that the 
tubes have a layer of transparent tin oxide deposited on the glass, which 
acts as the anode. I assume that explains the wonderful colors you get on 
these 'tubes' - like the colors on a soap bubble.

[neonixie-l] Re: 74141 decimal place

[Paul Andrews]

On most tubes, you only need an additional resistor on the decimal point if 
it can be turned on with no digit being turned on at the same time. If it 
is only ever on when a digit is on, you will not need an additional 
resistor. I have no idea why.

Of course, this also means that if you want to display the decimal point 
both with and without a digit being turned on, you will need two paths to 
ground for it.

But yes, if you use one 74141 for all the decimal points, you would only be 
able to display one at a time.

Re: [neonixie-l] 74141 decimal place

[Kevin A.]

You could add an MPSA42 for each extra decimal point. Or use a chip with
more outputs like any of the Microchip HV series (5522,5530,5523, etc).

[neonixie-l] 74141 decimal place

[John Snow]

I'm trying to use 74141 drivers (intentionally), they have enough outputs 
to drive 0-9 per tube; but not including a display point.

I'm hoping to use a seperate driver to drive the display points (with an 
approproate resistor to reduce the current from numerical display levels)

Will this mean I can only have one decimal point active at a time? 

I don't have the parts to breadboard yet, so stuck to theoretical.

Seems to be same tubes that have already been discussed here:
