Re: Audio Frequency Counter Recommendation

Yes, I have one too. But aren't most of these 3-1/2 or 4-1/2 digits? I'm hoping for 5 digits, with a 1Hz resolution, if that's possible. In other words I would like 12,345Hz to show up that way, not as 12.3 with a 1K multiplier.<p>Any ideas?

Re: Audio Frequency Counter Recommendation

An interesting idea, but I was hoping for something a little handier (more portable) to use on the bench. My electronics shop is in the basement, while the computers are on the second story of the house, so that idea probably won't work well for me (although it does sound inexpensive). In any event,...

Audio Frequency Counter Recommendation

Would anyone care to recommend an audio frequency counter? I almost never work with circuits beyond 30KHz or so, so the fancy RF types are overkill for what I need. A five digit affair would be great, with 1Hz resolution if such a beast is available.<p>I don't mind building my own if anyone wants to...

Re: use midi to generate on off logic signals

Back in October 1997, I had a construction article published in Nuts & Volts on how to build a homebrew MIDI drum controller. Shortly thereafter, I discovered that the exact same circuit board could be used with some jumpers in place of capacitors, etc., to implement an 8-channel on-off controller f...

Re: Where are the LM566?

The NE566 is currently available from Midwest Analog Products. You might note that it was featured in the November issue of N & V, in my Clangora analog hi-hat cymbal project. I love the chip.
