Testing the TK Tar Baby

[poynt99]

My guess is (and I posted this also back some time ago) was that Rosemary made an error, and mixed up the model numbers of the FG and the scope. The scope they used is a LeCroy 324 WaveJet.

So the GFG part may be correct.

Here is reference to that discussion back in January.

That's a "discussion"? I remember it well. You posted a picture showing that you can even read enough of the model number in the video demo to see that it is an IsoTek GFG8216 FG. Yet Rosemary Ainslie replied with this:

But we would then need to pretend that we were using an  -   Instek GFG-8216A.  Our model is - in fact a IsoTech GFG 324.

And that was the end of her "refutation" of your posted photograph.

So, the mystery remains. Could Ainslie be WRONG about something? Could she have made ERRORS that stand uncorrected?

WHERE is there any reference anywhere in the world, other than in Ainslie's paper, to the IsoTech GFG 324? I need to see the schematic of the unit they actually used, so I can see why it can't supply current to the circuit when every other FG in the world could do so.

Yes, I remember that part too. But she said,

Isn't this a denial of error and a proclamation that the GFG 324 designation is correct?

So, since Ainslie ALWAYS corrects errors and typos as soon as they are pointed out to her.... what gives? Either there IS such a FG as the IsoTech GFG324 and we are just too stupid to be able to find it on the internet (and she is too stubborn to post a link or a photograph or a manual reference or a store that carries them for sale).... OR..... somebody is lying AGAIN.


And if something so clear and easy to check as the model number of an instrument is... WRONG... in her "papers".... what does that say about the many uncheckable pieces of DATA that she has posted, like those scope shots that have incorrect captions?

Is Channel 1 really displaying an integral in this picture? How is that done, on the LeCroy that can only do one math trace, when the math trace is doing a straight multiplication? Is the caption in error? The NUMBERS in the scope's parameters box are a computed integral... but the trace shows no such thing, and an integral _value_ , not a trace, shown in this way is more garbage out from the Ainslie scoposcopy sandbox.

MileHigh - I missed this post of yours.I find this so amusing.  The MIB indeed.  I don't think anyone in their right mind would assume that any of you are MIB.  All I'm claiming is that there's a mission to deny any evidence of OVER UNITY.  And that mission does NOT rely on scientific argument.
I'm not sure that any of us want to know your identity MileHigh.  I certainly don't.  I quite enjoy your posts - as a rule.  Latterly they've become rather too transparently partial.  But as a rule they're quite clever.  And they usually have artistic merit.  And I have no intention of exposing picowatt's identify.  I've been cautioned against using their actual names.  But it'll come out in the wash.  That's for sure.
This is rich.  MileHigh the excessively responsible poster who also strictly follows forum guidelines - is threatening to report me to Stefan?  For what?  For defending my corner?  My character?  My competence?  And that defense is 'disgusting' as you put it?  You - of all people?  Trying to justify some elevated moral high ground?  Good gracious MileHigh.  I'm not sure that's an attitude that you can project in the face of your own slanderous accusations against me and your own general forum deportment.   And you think it's perfectly in order for picowatt to infer and imply  my lack of intellectual competence - to compare it to the competence of under sixes - and that he may do so without my 'defense' of those insinuations?  I must just sit back and allow this 'opinion' to be suggested as a 'fact'?  So yes.  Feel free to complain to Stefan.  Then I will remind him of your own slanderous comments and picowatt's.  And then let any fair minded person tell me if I'm expected to say nothing in the face of that slander.  If picowatt actually takes the trouble to teach under sixes the art of soldering - then I'll eat my hat.  I NEVER implied that I believed him.  I think it would stretch the credulity of the most utterly naive.  But there you go.  Clearly he's convinced you.

My Dear Rosemary,

As for stretching the "credulity of the most utterly naive", are you speaking of yourself?

Children between 3 and 6 years of age, are to me, at the most precious period of their life.  They are like little sponges for knowledge, so bright eyed and innocent.  They are in awe of the world around them and are always full of questions, trying to figure it all out.

Just as you will not accept how your circuit operates, you apparently cannot understand how children of that age group can possibly be taught to solder.  Possibly at that age, you may not have been able to be taught how to do so, but all that I have had the very great pleasure with which to do so, had no problem at all.  There was one minor burn, but two days later even she was back at it.  How else can a child learn what "hot" is anyway?

The circuit was a simple two transistor siren circuit.  I would premount the little speaker, the toggle switch, the pushbutton and 9V battery holder onto a 2" by 6" piece of perfboard.  Back then we used flea clips for mounting parts.  I would pre-install the fleaclips, crimp the components to the clips, and crimp and loop the backside busswire connections.  Any one who has done perfboard work in this fashion fully understands the process.  The transistors were TO39 packaged 2N2102 and 2N4036 which I always had plenty of, and the rest of the parts came from Radio Shack, which back then sold under the Archer brand (ring a bell to any old guys?).   

All that would remain is to solder the top side parts to the flea clips, and then flip the board and solder the buss wire to the flea clip tails.  At the kitchen table I would set up my TC202 Weller to the right and the perfboard was held on a PCB stand in the center.  A spool of solder was to the left.  I would have the kids, one at a time obviously, sit on my lap with our arms alongside each so if a burn event looked possible, I could snatch the iron.

Now, all the child has to do is remove the iron from stand with right hand, wipe the tip the on sponge, tin the tip with the solder held in left hand, touch the tip to a preselected joint, apply solder to the joint, return the iron to the holder and then sit back and admire their accomplishment with a big grin from them, and praise from me.  There were maybe 50 connections or less in total to solder, and it took several days to finish the task for most, one joint at a time, several joints per session.  Once completed, they could turn on the toggle switch and when they pressed the pushbutton, the siren would wail with an increasing pitch for the duration of the button press.  Releasing the button would cause the pitch to decrease until the oscillator stopped.  Very simple.

After I did this with one child, the neighbor kids were in envy and I asked if they wanted to give it a go, and they did.  The small monetary cost and time spent, was, I felt, a worthy investment in sparking the imagination of a child at that age, and instilling the sense of accomplishment that they were so proud of.  As much as they enjoyed their accomplishment, it was more a joy for me to see them running around the neighborhood annoying all with sirens.  They, on their own, discovered they could touch various points on the board and modulate the siren and were simply amazed at the sounds they could make.

I would suggest anyone with a skill in any field, take the time to share it.  I've seen 5 year olds help Daddys change oil, and operate a grease gun.  And they, as well, are always grinning from ear to ear with their new found sense of accomplishment and smudges of grease on their face.     

I honestly cannot grasp how you find it so unbelievable that a child can be taught to do the simple steps outlined above required to solder.  Possibly it is more an assessment of your capabilities at that age.  Possibly you had no one that bothered to take the time with you.  I don't know, and personally, I don't care.  It was one of the more enjoyable times in my life, and the "likes of you" cannot in any way diminish those memories. 

So, move along, find some other gibberish wth which to fill this otherwise interesting thread.  I have no further desire to engage with you at any level.

And if you are going to eat a hat, I prefer that you do so with a leather or possibly felt hat.  Something very dry and chewy.

Good for you, PW !!

What you describe is very similar to what happened to me. I was one of those little kids ! Well, I was a little bit older, I think, but the neighbor across the street did something very similar for the kids in our neighborhood. He was packaging and selling little electronic kits, among which was a crystal radio. He showed me a lot of stuff that I still remember today. Who could have thought that simply putting a loose loudspeaker (for my one-tube radio) into a box could improve the sound so much? My father especially was amazed.
