[neonixie-l] Question on Russian IN-14 kit

2011-11-25 Thread Dylan Distasio
Hi all- I picked up a Russian nixie tube kit on eBay which I just received. It's got 6 IN-14s, each wired to a separate PCB with a 74141 on each board. I'm not sure if anyone on list has built one of these before, but I wondered if anyone has any tips for controlling all 6 digits for a clock

I just use the brute force method of using a 40 pin DIL PIC. Nice and easy. Nigel. - Original Message - From: Dylan Distasio To: neonixie-l@googlegroups.com Sent: Friday, November 25, 2011 3:37 PM Subject: [neonixie-l] Question on Russian IN-14 kit Hi all- I picked

Thanks for the comments. It might be a good exercise for me to wire up a PIC or something similar. I've been looking for a project to do some actual perfboarding versus a kit PCB, and it would let me do some PIC programming which I haven't done yet. One other question if you actually have built

And just one question. I checked the shipping prices from Mouser and Digi-key. They were both between $100 and $120 for a single item. Is it always like this (I am in Europe). In Europe, you'd likely do better ordering from RS, Farnell, or even Jaycar or Futurlec. - John -- You

In Denmark, you can buy from RS being a private customer, but you need to do it online if is't not in stock locally. We have a local warehouse in Copenhagen, and if it's in stock there you can pick it up at the counter and pay by cash, but if it's not in stock, you'll have to order it online

Measured 54.7mV. I guess that is fine. I can't measure the voltage between the base and the emitter on Q2 yet. Don't want to put in another FET and burn it like the other 3. I want it to be the last thing. Making too big of a deal over the FET. Unless you're really cranking out some current
