No, a CD4511 can't drive a nixie (B7971 or any other) directly. You need to add those HV xstrs (MPSA42), with 42 base resistors (22K ea). You can substitute some old fashion SN75468 relay/lamp

Instead of buying a meter, how about making your own, 'old fashion' style LCR bridge, with a magic eye tube (to keep it somewhat on topic): http://img835.imageshack.us/i/cdbridge.jpg/ That will be a

I am using a Stamp to drive the binary pins on a 74141, I have the 74141 powered with +5V, and ground. I know my code is good (tested with LEDs, all checks out, the binary adds up and is timed

Besides my single-board IN17-based 7 digit, I did a HH:MM:SS:T display board with 8422s and one IN17 for tenths; This board is compatible with the same board I am working on.

Lovely little gadget, that meter is. Matter of factly, I love instruments in general, and how they are able to decypher things. One of my favorites is my digital caliper and I love to try to trick it

That's right, Dave, I've got my metric conversion mixed up, sheesh. 220,000 nH - not pH - amounts to 220 uH. On the other hand, the "224" inductor is indeed the size of a fingertip (the 'pinkie',

I "still" want the one for B7971 6,7,or 8 tube (So, 2x chained) Michail

Marco, The 224 is indeed 22 followed by four zeroes, or 220,000 of whatever unit the manufacturer decided to label the part with. Often that's nanoHenries. You can tell at a glance which of nH

Totally agree - your brain is the best test instrument you'll ever have. But if you want the fancy piece of equipment route, then get yourself one of these:

Or, if you don't have a RLC bridge you can do what I have done to measure hand wound coils. I use my function generator to drive a circuit at a known frequency and set up a voltage divider with the

Depends largely on the manufacturer. For a 220uh inductor, you'll commonly find it labeled 221 or 224, for 'uh' or 'nh', respectively. See if you can make out the maker of the part, and refer to their

Hello, I understand that I'm not answering your question, however, I believe my comment is relevant. One of the best investments I have made into my test bench was buying an LC-meter. I got a

Howdy. Here's a basic question about the labeling of inductors (those that resemble small electrolytic capacitors), commonly used in switching power supplies. I searched the web on the answer to this

So I don't bog my own thread down, I've PM'd Nick to ask about some preliminary design questions. Since there appears to be some interest, I'll make sure to update the thread as I get further along.

That's why I like Dekatrons: http://www.dailymotion.com/video/x7z7xo_time-bucket-first-single-dekatron-c_tech http://snipurl.com/103vmv

A standard 7 segment tube representation like a Russian IV-12 VFD, for example, displays a single center segment to form a block digits 2,3,4,5,8,9 -- Now imagine that same numbers on the 7971 which,

Can anyone tell me if the CD4511 can drive B7971 Nixie tubes directly or must I have each tube segment driven in addition with mpsa 42 HV transistors? I basically want to use the CD4511 in place of
