Tinsel
One way or the other, we'll make it happen!


You can take that to the bank.....[the promise]


Chet
PS
Just to be clear ..
The offer would be for actual out of pocket expense ,door to door !
Also anyone that can offer help [Fuel Lodging Etc]
contact me at
ChetKremens@gmail.com


and Tinsel
I have all experience from Customs to whatever...?
there are no strings attached ,EVER...

Chet,

There are hundreds of people that have benefitted from TinselKoala's unselfish generosity.
Its time for builders, posters and lurkers alike to step up and do the right thing.

Contact me privately here, with a name and address to mail you a money order.

Count me in for $100.

Is there anyone else reading here that would care to contribute to this project ?

Boss
Thats what it takes....


Nothing but grattitude here,and a promise...


I will not take one cent more than the cost of the "project" actual costs, no fee from me.
we'll figure it out.
Thx

PS
Nor will I except a cent until all details have  been worked out with TinselKoala and involved parties.


I will except good faith  pledges  ,this is not in any way a vacation ,It will be a non stop Run from start to finish [sleeping in the vehicle if need be]


probably a 4000 mile run.....

Hi :Boss: long time no hear, I thought it might be you. I hope things are going well for you at last. Thanks for the nice comment, but there are probably just as many people or more, who might donate to a fund to _prevent_ me from retrieving my gear and being more active! Certainly I get more insults and disrespect here than the "average bear" gets.   

Chet, you are talking about driving with a trailer into the Toronto area in the coldest winter we've had in a while? Sleeping in your car? You could easily get buried in the snow, frozen to death on the highway. And who knows what will happen at the Customs entry point. I'd feel much better if the stuff could just be shipped directly from Toronto by a Customs broker/shipping company like Kuhn&Nagel. This might cost a bit more, but it will avoid you having to deal with all that snow and the terrible traffic along the Canadian 401 "freeway" which is the most ridiculous, traffic-congested road I have ever been on. Ten lanes, count'em, ten, in either direction (out near Pearson Airport anyhow) and even in good weather often bumper-to-bumper stop-and-go. They even have tow-trucks pre-positioned in clusters along that highway so that wrecks and stalls can be cleared quickly enough so that people don't freeze to death in their cars. But I just don't know what to expect, maybe the trailer idea is better after all, if the weather is good.
Fortunately there is a Motel 6 (my choice for travel accommodations) with reasonable rates a few miles west of the location at the intersection of Winston Churchill street and the 401. This is on the west side of Toronto, though, and the GDS location in Oshawa is beyond the east side of Toronto, at least an hour, probably more like 90 minutes, of drive time away.

We start at the bottom and work our way out  , from worst case to "best case" scenario..


The plan will Coalesce ....


"The Boss" is  honing one aspect ,a few more to sort out...


Don't sweat the details yet,The plan is still coming together!!

There is a much simpler dual-direction drive pulse motor.  It would be a variation on the MHOP.  The pick-up coil waveform has all of the information you need to make a dual-drive pulse motor.  There is a positive hump, then at TDC it transitions through zero volts (or your reference threshold for a single-supply design), and then there is the negative hump.  So you use one op-amp comparator to detect the positive hump and a second op-amp comparator to detect the negative hump.  Then you use the two op-amp outputs to control the H-bridge.  You can recover the spike energy, etc.

If you wanted to go really crazy you could add a "power-boost" to the H-Bridge.  When the comparators flip you trigger 555 monostables.  The monostable outputs go high when you first energize the coil for both the attraction pulse and for the repulsion pulse.  These signals control separate MOSFETs that gate separate higher voltage supplies.  The brief pulses of higher voltage kick current into the drive coil faster so that the "push" kicks in faster.  The current from the main supply voltage is shut off during the kicks using diodes, a.k.a. "diode logic."
