I see the location nearest me is also advertising a job opening for a multitalented person who can do all sorts of things and who has experience.  Wages 11 to 14 dollars an hour, d.o.e.! But the skill set they say they want is worth 40 dollars an hour at least.

well the drive to and from would really honk ... but consider this if it makes sense:  i believe you would get your membership for free if you worked there.  you would really be an asset to teaching i am sure of that.  so you could teach a little and get paid (granted not a heck of a lot) and do research with some of the most expensive equipment around at a bargain.  just my two cents - love your work and would love to see you have the tools you need to carry on and educate us more!!

love your videos!!  you are one of the reasons i got interested going down this path ... still don't understand half of what your saying most of the time but it will come ;)

Well, thank you for that kind word. If I lived within a 10 minute drive from the place I would actually consider applying for the position, and I believe that I am indeed fully qualified according to what they listed in the "job description" (if a bit "over the hill" in terms of age). But I don't. I live, as I said, about 120 miles away and the road between me and there is both truly frightening to drive on and goes through a major city with huge traffic jams with no alternate route that is reasonable. For example, it takes only slightly over an hour and 15 minutes to get from my location to the edge of the city in question... then it can take another -full hour- of stop-and-go traffic on the "freeway" to get through that city and make it the extra 30 miles or so to the location of the shop. Making the drive on a daily basis is simply out of the question for me, and that kind of relocation on a permanent basis is impossible at this point in my life.

I am happy that you watch and enjoy my videos, and I am happy to explain further anything that you don't understand about them. I always respond to comments on the videos, so just ask your question in the comments to any particular video and I'll do my best to explain anything you don't understand.

Tinsel
there was A show on the TV about a similar facility taking root across the country .
In this particular show they were referring to a fellow that would freelance for the group
as an operator ?[charge small fees]


However...
Lets get your stuff back !!
If I do indeed go North to the GDS test ,I will make every effort to Get Your stuff back this way.


I would actually consider Just  "doing it"  if I found a time window...


You do a lot here ....


thx

Yes, if you do wind up going to Toronto for the GDS testing, if you could spend a day or two packing and arranging shipping somehow that would solve a big problem for me. If you can let me know when your travel plans are finalized I can get permission from the owners of the lab for you to visit and they can point out my stuff to you and probably help with packing and such. They aren't interested in helping beyond that, I think. (They do tend to take some days off during the winter holidays though, which might be a problem if your visit is really going to be in mid or late December.) The lab is located within a stone's throw of the Pearson Int'l Airport.
I don't know how much it will cost, though, and as you know I am out of funds totally. However there are three Curta calculators in the stuff and I am willing to part with two of them (an early Type 1 and a later Type II)  and they together are worth over two thousand dollars. I'd like to keep the one Type II that I had fully repaired and refurbished by Jack Christianson at TimeWise, but I could even be persuaded to part with that one if absolutely necessary. It is a rare early black Type II and should be worth 1500 dollars just by itself. But I sure would like to keep it if possible.
The stuff consists of a complete Sherline "miniature machine shop" lathe and milling machine with digital readouts and most every other addon in the Sherline catalog, a fullsize 3-layer Kennedy rollaround toolbox stuffed with tooling and calipers and dial indicators etc. for the shop, some test equipment like power supplies, an oscilloscope or two, some meters and other stuff like that, and including several of my constructions like all the VanDeGraaff machines, the Dirod, and so on. I can't remember if the Nord Lead digital analog synthesizer is still there or not; there may be a few items that my old landlord still has in storage, a few blocks away from the lab. When I left Canada the last time I was seriously ill and could not make any arrangements, I actually thought I was dying and could barely handle getting myself out. Unfortunately I didn't die   ;) , so the mess is still there, and I can't clean it up myself, I need outside help. It's a pretty big job and I have no way of compensating or paying for it other than by selling or offering the Curtas.  I'd guess it would be about two standard forklift pallets full of stuff in boxes, and I think that the lab would donate the pallets and help to box the stuff up and secure it. I have no idea about Customs duties; most of the stuff is actually made in the USA like the Sherline stuff and the Kennedy boxes but a lot of the tooling is from all over the place. It's a complicated problem.
Thanks for even considering it; if it doesn't work out or you decide it's too much trouble or expense I fully understand.

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.

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."

lol That's pretty funny.  I think the 401 in Toronto is the busiest and greatest superhighway in the world!  It's more like 12 to 14 lanes.  It just shows you the economic prowess of Toronto that it's reaching it's capacity(?).  (I haven't really checked this information.)  If you are a native Texan I supposed I shouldn't be surprised about the "Canadian Igloo" talk but it's not Siberia!  Actually since the mid 1980s some winters can be quite tolerable.

You gotta still give the planners in the 1960s that designed the 401 a lot of credit.  When it's not at full capacity it's a fast and safe road.

Some digging:

Busiest highway
 
Highway 401 – the Macdonald–Cartier Freeway has volumes surpassing an average of 500,000 vehicles per day in some sections of Toronto as of 2006, giving Highway 401 the distinction of being North America’s busiest highway.
 This surpasses the Santa Monica Freeway in Los Angeles, and several Interstate freeways in Houston, Texas.
  King’s Highway 401 is the primary through route across Southern, Central and Eastern Ontario. Since the highway’s completion in the late 1960s, Highway 401 has evolved from being a convenient bypass to a vital economic corridor.
 Today the stretch of Highway 401 that passes through the Greater Toronto Area ranges from 6 to 18 lanes, and the stretch between Highway 403 and Brock Road in Pickering is thought to be the world’s longest continuous stretch of highway having 10 or more lanes.

Well
Having spent My entire life in NYC area dealing with a population the size of all Canada
in just these few north eastern states,I can assure you I can redefine "traffic" and "crazy drivers".
I have easily driven over one million miles on these whacky roads..


that being said,  between myself and Toronto they are expecting a 5 foot snowfall "Today?"


Five feet in One storm ,   Buffalo NY.....
Yeeesh I don't know how those folks can live with that Lake effect storm system??


thankfully I am far enuff east to miss its vast reach,although the Subaru AWD does Laugh in its face
and having driven most of my life with only rear wheel drive ,the AWD "RUU" feels like a tank in the snow.[rigging a plow for it this year]


@TinMan
@DogOne
do you want me to extend a formal invitation to Bedini ,Lindemann and Aaron for a "representative Entry"into the contest.
A gentleman's invitation ?


I did ask one fellow at a thread there for some info on their "self running Motors" [he is investigating]
and I absolutely do NOT want to get into any Claims discussions here.
I just want to "formally"Invite them... with a yes or no RSVP?
is that OK?
lets keep it very friendly .


I will clear it with Russ too.


thx
Chet
