I'm available for projects

I first kissed a girl at 7, and was made fun of more for that than for doing experiments.

The amps in old Tek scopes also go bad, and there's a market for replacing them too. I suggested years ago that somebody should make a DIP module to replace them. Today's standard op-amps could do it I bet.

A lot of Tek scopes use weirdly high supply voltages.

Did you complete the audio compressor/limiter you were working on for a bit? Mikek

Ummm, that may have been me. It is only a concept right ow but the principl e is that the microphone input is shunted by FETs. I want to lower the dist ortion of the microphone by actually damping the excursion of the diaphragm . I also said I want to set up a test fixture to prove that it actually doe s that. People said I am unlikely to be able to prove it, but I think I can .

Even if not, the thing is a bank of FETs variably shunting the input direct ly so it cannot be overloaded. I also intend on a few other features as wel l, but the FET shunting is the main thing about it.

I did post about it but could not find suitable FETs, but then it occurred to me to just use a bunch of them in parallel.

I think I can design the whole thing myself but not completely sure. If not I will probably give you a call. I have not even written it up ad presente d it to the money people. There is one component to this thing that is new, the rest of it is old technology but belongs there.

I can demonstrate the concept, but that means taking out one of my blank PC board and cutting up the copper with a Dremel and actually making that par t of it. I have to scrub the shit out of them because they have photoresist on them.

But I DO have a working HP339A which measures down to 0.0016 % THD+N. When I do the demonstration it will be on a video from start to finish. That wil l make sales. And I have the market at the my fingertips. I really should m ove faster on this but I am lazy. To be honest, I am tired of working perio d, I just want money. Then whatever I do is a hobby. That is IF I can get s omething like this of the ground. I hope it is not like the F-35.

But there is some shit I must do first just to prove the concept. First I n eed a design, and I do that on paper. Then I need to prder a bunch of FETs, then I have to get out the Dremel and and make this compressor, which is r eally not, it is a damper. I have looked at the FETs out there and determin ed that the best thing to do is to use about 12 of them per channel. Six pe r side of the XLR input.

But it is all analog, not a digital piece in it. And the final product will actually have a reverb tank like a guitar amp but will mix in to L-R, in o ther words in opposite polarity in the channels. Then there is the issue of equalization.

All analog, runs off a wall wart so there is no UL, and it is probably simp le enough I can have it built by one of those companies in Solon and can th en say "MADE IN USA". Get up0 a hundred bucks for a provisional patent JUST ON THE DAMPER CIRCUIT which should be easily prosecutable and leave the Ch inese out of it for a while and keep all the money here.

Later, we just let RSQ make it, which has everything made by Apex, wherever they are. By then the patent isn't worth shit, so just get them built chea per and make the money.

I would like to see a price point at about $250, and I am pretty sure the p eople in Solon can make them for $100. Later, we shift production to China or Korea via RSQ which we own half of and just forget patents and all that and make the money because we have the market.

By the time we lose the market for whatever reason, I will probably be dead . I am not healthy.

I'll call you if I need you, and that won't happen until the money people O K this, so it will be there. If they do not want to do it, then we talk a w hole different thing. I can find their competitors. I can deal with someone else. I can also finance this whole thing myself but I don't want to.

I'll know more about how tis is going to go in the next couple weeks. I thi nk they'll bite, and bankroll the thing. Why they bought into RSQ is a f*ck ing mystery. Maybe they're rich and this is just a hobby. If so, so what ? As long as they put out.

As I recall it was a personal project, you had ask a question here about it. I'm interested because I use an FM transmitter to transmit my internet radio audio around the house/yard. Some internet radio signals have high volume some have low, and sometimes it's different between programs*. I'd like to level this, without adjusting the transmitter input level each time I switch internet stations.

Did you ever listen to these radio shows as a youngster? Gunsmoke, William Conrad voices Matt Dillion, The Six Shooter with Jimmy Stewart, Dragnet with Jack Webb, Bold Venture staring Humphrey Bogart and Lauren Bacall, The Adventures of Philip Marlowe, Our Miss Brooks with Eve Arden, and of course The Shadow?

  • I often listen to Old Time Radio Programs, and there can be a level difference between shows.

Are there movies with dialog anymore?

What bugs me in the incessant need to have dialog-overpowering "background" music. ...Jim Thompson

No. LOL

My Grandfather used to bitch about that back in the 1960s or so. He also pr onounced "technicolor" with a long "I". Like "tek-nye-color". They have be en doing that for some time now, but it has gotten worse lately. Surround s ound makes it even worse actually, to the point where they had to add that center channel so you could even hear the dialog. I remember my system in t he early 1990s which was quadrophonic and I didn't have that problem.

Talk about a mess. I had the Advent 60" with the silver screen and the mirr or in front. Matarnz quad in strapped mode with the rears going through a S ansui, separate equalizers for front and rear, both bet and VHS set up to h e able to record both ways. Just the cables cost as much as a cheap new TV.

But watching Days Of Thunder the cars going around the track really did go around the speakers. On Star Trek when the Enterprise came at you and went off screen, the whoosh noise did move to the rear speakers.

But the dialog was loud enough to hear, plus these movies had a real plot. Not just special effects, which seem to be the trend now. Not that I would know. Hell, I got 20 or so movies on my PC I haven't watched. I might die f irst, but then whoever gets my stuff can watch them, if they can find them. I do not let Windows put my stuff where it wants, I make a new directory. Lately I've been using My Documents a little too much but I will get around to moving stuff out of there.

Also about this new media, some of it looks like they let an eight year old run the camera. Looks like pan and scan all the time but it isn't. That is how the idiots wanted it shot. I can't stand it.

And now, for example my Mother watches some TV. we have had the discussion about the fact that back when we only had five channels we had to sit down and talk about what to watch, like on a Friday night. Now we got 500 channe ls and there is nothing on that is worth a shit. She is down to watching re ality TV, she has been through all the Gordon Ramsay stuff and the Hoarders and is now on the ones where they flip houses.

No plot. No creativity unless you count their feng shui. But there is anoth er thing, who buys these expensive houses ad wants them already remodeled. I want the place old and I will pick out the stuff. I wonder how any people buy those houses and just tear half the shit out and do it their way.

Anything I would watch would be 20 years old or more. Like Outer Limits. Bo th the old and the new, they brought up interesting issues actually that pl ayed on the mid. Moral issues about what should be doe with certain technol ogy ad whatnot, but even the new series started in 1995. If you ever watche d Star Trek you know how they are, and most of them are 20 years old or mor e.

But now, I have burned through about everything I consider watching. I go t hrough the lists on hulu and there is nothing, even paid, that intrigues me at all. I went through a bunch of stuff on youtube, and believe me with th is older software I get really good video performance. It always nags me to update but no way, it works just fine. Kick it into full screen and it is like TV.

But there is nothing to watch. So what I do now is talk politics and get th rown off of websites.

People say that all the time, I must disagree. What are your interests? Plenty of science programing. Movies, pick your type, you can watch full length old and new movies, 10's of thousands. Detective shows, real life police dramas, comedies, cooking, I enjoyed the the guy that did the science of cooking, Alton Brown. Car shows, weight loss, I'm in awe of the 600lb people, how in the hell did they do that. Plastic surgery, history, omg, how much history can you take in. Poker, motorcycle and car racing, sports of all kinds, documentaries take your pick of topics, never ending. There's so much more and that's just on any number of streaming TV media players, heck you can even get cable and have more! On the other hand, if you have any kind of life, there's not enough time to watch all the TV you want to watch. Mikek
