I'll add my 2 cents to what I want in a meter. A true RMS meter, that goes into the RF range. Linear Technologies use to make a chip that helped do that: http://www.linear.com/product/LT1088 Unfortunately, its been discontinued, but the concept still applies. How you implement the greater

[neonixie-l] OT: Rant - eBay Sucks ! Shipping Calculator

I've been having a little (losing) battle with eBay lately, on about international shipping. I've been shorted on 4 transactions, in the last month. Their customer service reps are totally ignorant of their own policies. In the modern age, that, sadly, seems to be the norm. I've made 4 calls.

[neonixie-l] Re: New clock kit in the making

Now that's a neat concept ! Someone talked about using neon bargraphs (IN9 or IN13) to make an analog clock, but I don't recall actually seeing one. Or maybe I did, and just forgot. Anyways, nicely done ! One of the bad things about getting old is the memory going. On the plus side, I can get

[neonixie-l] Re: Dekatron Experiments

Oh, yes, its a timing issue. It works fine with the guides detached. Its just more of a curiosity. Flipping the guide pins does make it switch to K1. I'll have to analyze my circuit timing more closely to discover the actual mechanism details. The reset is issued at the same time as the flip.

Well, those who know me, know that I have attraction to dekatrons. Here's some of my latest tinkering. A long while back I designed a 4000 CMOS base pendulum circuit. It used a 4017 counter, and a 4013 flip-flop. I revisited that circuit, and came up with one that just uses on 4518 dual
