You don't happen to have any documentation of what those "dots" mean, do you (if there was even any kind of standard)? I have a bunch of salvaged transistors whose only markings aside from EBC is

I've seen shorted numbers in a IN-14 and a IN-4. I believe the IN-14 was also between 5 and 6. - Michael Sangster --- In NEONIXIE-L@..., michail1@... wrote:

Or not. Best datasheet ever: http://www.national.com/rap/files/datasheet.pdf http://www.national.com/rap/Story/WOMorigin.html

Datasheets contain the basic reference on particular components. Its how we sift out candidates for certain applications, and refer to details on parts already used. Depending on the part, a datasheet

Sorry about this, but I made an error when I said that the binary input pins of the 74141 are 2,3,6,7. They are not 2,3,6,7 !!! Consulting the data sheet, they are actually 3,4,6,7 Where Q1 = pin 3 Q2

Not difficult at all - Jan Wuesten is your friend... http://www.die-wuestens.de/eindex.htm Select the section on "nixies"... Nick

Hmmm, interesting indeed. 10 pc price from Newark in down to $120. And the lead time while long, is shorter then for some Atmel processors that I'm low on. What's the situation with ZM1350s these

Hello - That is a nice collection. Is that flat 7-segment tube the neo5000? I have a few and I've been trying to identify them for a while. Do you know where I can find any data sheets on these?

The 74141 (like all DIP ics) has a notch in the center of the package at the "top", which is between pins 1 and 16. Some ics have a dot near pin 1. With the ic facing so that the pins are pointing

Greetings, Does anyone have interest in Vishay plasma displays? http://www.vishay.com/displays/plasma/ The 1x4 char, 16segment, 2x1" char PD-04A200 gets my attention: Also, 1x16 char, 14 seg.,

I have been looking for quite some time for these. Haven't seen them on ebay either. Are they harder to find than the B-7971? Michail

Heh, funny you should mention that. I found this just the other day: http://us.cactii.net/~bb/propclock/ He claims he got about 600mW this way. Should be easy to find discarded video players right

First of all, simplify your circuit for troubleshooting. Get that stamp out of there, and use four plain SPST dip switches with 2.2K pullup resistors on each of the binary input pins of the 74141 to

I love mechanical stuff that you can look at. I can watch 'Rube Goldberg' mechanisms all day ! At the start, lets put the idea on the table, and worry about implementation details later. The wilder

I don't know about everyone else, but while I understand a fair bit of it by now, I don't consider myself "fully equipped"! I still puzzle things out, try things out on breadboards, try to figure out

quite right "union jack " sounds so much better DLW
