Easy. These are the pulse actuators that prime the flux capacitor.
They look like genuine Mr Fusion parts and not the doc's protos.

guessing maybe vacuum caps or a specialty tube. i can't see the backside if there's another set of contacts or have reference to the actual size of them.

Post by: boB on March 12, 2013, 04:03:06 PM

I tend to agree with Niel.  vacuum variable capacitors ?

At first I was thinking what DGD was saying  (spark gap triggers) but looking
at the shafts, I would say caps.

IIiiiiii'm gonna go in another direction, and suggest some kind of magnetic actuator - a piston.

Yep me to as the shafts have holes in the end for a pin and they do not seem to be turned the same (Indicating they can turn)

VVC is the correct answer. Neil & boB will receive nothing for their efforts as promised. No salesman will call and no vinyl discs were harmed in order to bring you this tooney lunes presentation.

Post by: dgd on March 13, 2013, 03:48:44 PM
VVC?  I can see how this mistake occurs. These first appeared about 1985 in various devices. Initially purpose unknown, testing showed a variable capacitance based on a vacuum contained actuator.
It was only later discovered that this was in fact an ionic chamber with inertial damping, purpose unknown. When a Caltech intern, late for a review meeting with his professor, had the device on the front seat of his 1978 Porsche 911s, he was surprised to notice the device 'alive and profusely discharging energy like a miniature lightening storm', when he exceeded the speed limit to 88mph.

It's unfortunate that you posted these images.

If we're lucky, they've not been propagated across the internet yet and you can take them down. If Dr Emilio Lizardo sees these, then it's practically unavoidable that a new oscillation overthruster will be built, and we all know how that will end.

Please take these images down, and get these two remaining units to the nearest outpost of the Blue Blaze Irregulars, so they can be secured properly.

We're talking major baby bangs here, red lectroids , , bad news.

Lets make this one a little more difficult. Guessing the function is not going to be enough. Looking for model and manufacturer. Perhaps a clue? boB & Robin are indirectly connected somehow.
Title: Re: What is it?

Not manufactured by Outback or any company owned/operated by bob/Robin. Heavy on the "indirectly connected" angle. Pic taken with a bright light on the backside of board. A better shot here.

ok i'm stumped as i could guess at the function, but i couldn't say what the make and model is off hand. one possibility may be an equalizer, but i'm not sold on even that. now it's hard to tell, but if it has many inputs as the arrows could indicate then it could be a mixer.

Post by: boB on April 14, 2013, 03:01:05 AM
I have stared at this PCB for a while but I do not know what it is.   I can only guess a few things.

It is single sided and uses what looks like XR 4136 quad or the XR dual op-amps ?  1970's or
1980's vintage audio product of some sort I would guess.  I definitely recognize those DPST
pushbutton switches though.  Alps ?

Internal power supply with power switch just left of center on the front panel.

Eight --8-- pushbutton switches on the front ?  Hmmm...  Audio pre-amp select switches ??

Phase linear or Carver pre-amp ?  Or, if not that indirectly related, I'm not sure.

This is a good one !  This is a great game !

OK, wild guess.  I would have to lean in the direction of slightly newer than phase linear so that would
be Carver Corporation.

I was not real familiar with Carver Corp. products except for the mag amp cube so I'll guess,  Holographic preamp ?

Mickey and Trace? :)

OK, time to give it up! A ProSolo Autocross course map. All the dots represent pylons or traffic cones that define the course. Top center, two cars line up and stage for a drag style start for the first 200-300 feet then one car veers to the left side, the other to the right side and both navigate through the pylons as fast as possible. Laser lights at the start and finish just like the drags but with a lot of twists instead of just a 1/4 mile long straightaway.

After the finish the cars swap sides and do it all over again.

BUT, if you knock a cone over it's a 2 second penalty! Go off course, outside the defined path, it's a 10 second penalty! Low to medium speed precision racing...lots of fun! :) All kinds of car compete. Run what ya brung is the theme. Ex Cop car complete with spotlight? Sure! 700HP Nissan GT-R AWD? Yup. Corvettes, Miata's, Mustangs etc.

boB

A ring mic is used to check the ring gap. Depending on the application there is a minimum and maximum gap spec. .010-.020 for example.

Turn the big knob and the band closes or compress's the ring. Not a very common tool. Any competition engine built correctly will have each and every piston compression ring gapped to a very specific spec and matched for the cylinder it will be installed in. It's also very handy when rebuilding any engine to make sure the gaps are all within specs quickly.

Now I suppose you want to see pics of the "ring grinder" I have that removes small amounts of material from the ends of a ring to increase the gap? Old school is clamp the ring in a vise and carefully file the ends, install in cylinder without the piston and check gap with a feeler gauge. But hey, power tools are always more fun!  ;D

Some 7400 quad nand gates and wood have to look in my old TI data book for some of those

boB, 1972 is correct vintage.  :) Your nose is leading you in the right direction....but it's not CRT or a video game... :)
Very close..but off just slightly. A hint: Some are still in use today doing exactly what they were designed for. Certainly not obsolete by any means.

Credit to rossw for coming up with display/counter. Tecnodave got it spot on with frequency counter though.
On the readout what you see pictured is with no input to the counter.  A switch was added by previous owner that shows the 94.xxxx in one position and 00.000.0 in the other.

Have not connected it to any of my Heathkits yet to confirm it actually functions properly.  Should get around to that soon!

Generates Radio Frequency signals for testing and tuning receivers. I tuned two way radios including HF and VHF for bush planes, marine, early car phones , and land mobile two way such as law enforcement with this type of equipment back in the 60's and 70's
Booton was the industry standard for commercial, but amateurs and hobbyists often used the ones pictured. The B&K was made for for tuning early TV receivers but hobbyists adopted them for all sorts of developmental designs and repairs.

SR-71

You got it.  We recently were at the Evergreen Aviation Museum in OR where they have one on display (they also a full scale mock up of the X15).  It blows me away that this was built in the 1960s.  My dad worked on the electronics design of the plane's inertial navigation system.

Yup! I was there June of 2008 about a week or two after they had just opened the new space museum across the parking lot from the air museum. They were still hanging planes from the cranes etc. No pylons blocking off the SR-71 so I was able to get up close and personal to it.  :)

Not a projector, but after you'd shown a film you had to rewind it back onto the original spool to send back. Rather than wasting projector time, you'd load the despooled film and the original spool onto one of these to put it back!

I know, traffic cones are boring! We use the cones for racing and when new they are very soft and tear easily when hit. So they get to "cure" on the roof for a few months exposed to UV so they will last longer.  :) In Autocross racing the cones define the course and do get abused! Hitting cones results in a penalty so we try to avoid it.  ;D

Nope.

This unit contains a "blank" another "blank" another "blank and yet another "blank". It's function is to "blank" a stable "blank' compute and "blank" the resultant "blank" or "blank". By understanding what it does and how to use it will result in maximum satisfaction.


If the purpose of the "blank" is to "blank" the various "blanks" and a "blank" is used then the "blank" should be "blanked" or the "blank" removed to prevent the possibility of "blanking"

boB has it the closest by stepping outside the boX, and reading between the lines... :) After a quick search on Google I did discover boB was even closer than I thought. Good job boB! A big box of nothing headed your way.. :)

"Don Stoner and Pierre Goral formed a company called SGC (Stoner-Goral Communications) in 1972, which made Marine-band radios. Once again, Don’s single-sideband knowledge and savvy marketing skills helped lead marine radio out of the "Ancient Mariners" mode (AM) and into the world of SSB".

And this,
As the saying goes: "The rest is history", because Don decided to make a single-sideband radio for the enthusiast, desgined by the enthusiast! Setting up shop in the John Hancock building on Mercer Island in Washington, a tremendously well designed radio began to taken form. To begin with, the rig was designed as a Sideband ONLY transceiver from the ground up.

The what is it?

It's a Stoner PRO-10, Ten Meter SSB Ham Transceiver.

Title: Re: What is it?
Post by: boB on June 09, 2014, 07:47:08 PM

Not sure if Don was still with SGC when he started the Stoner line of SSB rigs in the late 70's. He had a PRO-40 11 meter rig, the PRO 80-10, eighty-10 meters and the PRO-10 shown here.

Don went silent key back in 99.

I notice a date code that makes it look like this was made (or repaired ?) in the early 1990s at least.

boB ,

Where is that date code, I don't see a Motorola service center code, but not all service was done at Motorola centers.

How do you get a four letter ham license ? Do you admit to being on the bands that long? My original ticket has a four number code (commercial RTO).

Ah yes,  right track, wrong station,   It's motorola's economy line of 150 MHz taxi cab class radio, not their top of line Motran as used in Law Enforcement, don't remember the name but I remember the product line. I bailed from communications about Adam Osborne time and went into computers when they were kits.

Not Motorola or taxi cab class radio. It is however a 12VDC unit. The large pill is rated 25 Watt output and the smaller one at 30 Watts output.

Am I right that it is a VHF transmitter, it does look more ham quality construction as the rules and regs for Amateur Radio Service are vastly looser than Commercial.
I only worked in commercial and have tinkered with ham radio but never got my lisence.

This one is a "what is it used for" as the image is of the entire unit. The manufacturers tag has been zapped in the pic because it states "exactly" what it "is" used for.

This should mess with boB just a bit since it was used by the local Telco for many years.... :) Closeup of tag shown added by Telco.

The problem with old farts is it can be difficult to get anything past them.  :)

"Switch controlled by fly ball governor to control motor speed" is exactly what it is!

An OSKO, Over Speed Kutoff Switch, on my 1800 RPM Onan 12.5KW genset. It is set to open at an overspeed of 2250-2300 RPM and shutdown the genset. Old school mechanical magnetic switch but very effective. It's mounted to the end of the rotor/armature and the engine speed is of course controlled by a flyball governor.  :)

Dave is piling up the buckets of "nothing". Giving Westbranch an equal amount of nothing as technically it is a set of points for a motor... :)

We used to use something similar to this to pre-heat the oil in our old Radial Engined DHC3 Beaver.  During the  coldest parts of winter, we'd drain the oil after a flight and then pre-heat it before the next one.  We sometimes used a heater like the one in the pic.  Sometimes, we'd just use the heater under the engine with a tarp or two to build a tent-like structure.

How do you explain the fact that several units I own made by the same company using identical heatsinks and connections have been trouble free and exibit none of the issues you state?

These units have been in continuous use by me for 11, 14, 17 and 19 years. Each unit has the covers removed for an annual inspection. Dust blown out and all connections checked etc. Not a single bad connection or any corrosion has ever been found.

All have been subjected to numerous thermal cycles and thousands of hours of troublefree service. Less than ten years life? Not even close based on my personal experience and that of many many others.

While on the grid all of my electronics have an APC Smart UPS between them and the wall outlets. My oldest still in use was made in 1995. Nothing but new batteries every 4-6 years has been required. The majority of mine were made in the late 90's in Rhode Island. 1 or 2 made in the last 10 years are offshore, Philippines.

The one pictured here is a 2008 unit made in India... :( But considering what I paid, $40 and it works + batts were replaced 2 years ago by the prior owner I can't complain too loud.

Model is a SUA2200RMXL. 2200VA/1980 Watts. 48VDC input with extended run capability using external batts. 120VAC output.

Does not compare to my Radian on any level except weight! Sucker is 130+ pounds with 40 of that the internal battery pack.

But for $40 I'll use it for something..... :)

OK, sounds good. Thanks for keeping me in mind.  :)

I went back to where I found the 2200XL to look for a 9631 card but no luck. But.....They had just put out a 3000XL with not 1 but 4 of the external battery packs. Checking the model tag showed it was made here! Rhode Island 2003. Struck a deal for a couple hundred bucks for everything including a step down transformer that was in the stack but from another setup as this 3000XL is 120V in and 120V out.

Batteries are tired as expected. It works fine otherwise except for one issue. Transformer buzz while inverting/on battery. Normal "Hum" that is heard from most if not all inverters/UPS units while inverting but this one is the only unit that has ever produced a sizzling bacon sound. It's not present when charging etc. Only when on battery. Does this with or without a load.

The 2200XL does not sizzle on battery, normal hum yes.

Have you come across this with any of your units? boB feel free to chime in too... :)

Video of it here: AC plugged and unplugged several times during video. No sizzle when on AC.

I had an APC that would buzz real loud when inverting.  We solved it by peeling back the wrapping on the transformer and pouring some thinned lacquer in the windings.  Quieted it right up.

Your sizzling sounds like a small corona arc somewhere. Turn off all the lights and see if you can see any glow.  Can you smell any ozone when it is running?

I had several of the 3000XL units at work. If batteries were not loaded into the bays in the UPS itself, they would sound like an engine about to throw a rod. The best I could find out, the battery housing parts would vibrate at a resonant freq. with the transformers.

The second thing is the transformers as phxmark said. Grainger stocks electric motor lacquer in a spray can.  That worked well, but the high VOC's in the can required proper ventilation.

Title: Re: What is it?

CubeSat it is! :)

From AMSAT's site: http://www.amsat.org/wordpress/wp-content/uploads/2013/06/FoxBrochure-6-14.pdf

Project Fox is AMSAT's answer to the satellite communities' growing interest in
CubeSats. A CubeSat is a small satellite based on a basic 4-inch (10cm) cube
shape. AMSAT is developing a family of these satellites to take advantage of
new launch opportunities that are now available for CubeSat educational and
scientific missions.
The first members of this new family are the Fox-1 satellites as shown in the
drawing below. These are currently being developed by our all-volunteer,
AMSAT engineering team. They will use 70cm for uplinks and 2 meters for
downlinks. Each satellite will be able to operate as both an FM analog repeater
and in digital data mode. The satellites are magnetically stabilized using a
permanent magnet and hysteresis rods.

Each face of the satellite has a pair of high-performance, space-rated solar
cells. These solar cells drive maximum-power-point-tracking, DC-to-DC
converters that will wring out as much power as possible from the cells. This
power is used to charge a 10 watt-hour NiCd battery. The power system can
provide a little over 2 watts continuously, even in eclipse, and quite a bit more
peak power if needed.
The antennas are spring-wire whips and the VHF one is shown in its stowed
position wrapped around the solar panel. The UHF antenna is on the opposite
face. After deployment in orbit, they will spring out in opposite directions. Each
antenna will operate as a dipole. On 70cm, the whip and the satellite body form
the dipole. On 2 meters, the whip is half of the dipole and both the satellite
body and the 70cm whip make up the other half. The whips are aligned with
the Z-axis of the satellite which is magnetically stabilized to help minimize
QSB

Although not going to the moon an orbit about 400 miles up is on the way...too the moon Alice, to the moon! As Ralph would say. My hint about Orange, June 1st and can't smell were way out in left field....."OSCAR" as in Oscar the grouch! He can't smell and was Orange his first year, then Green. June 1st is his birthday.....gotta get creative with you folks!

Thanks for the hint, but I didn't need it.  I've seen descriptions of these... for some reason I think maybe you wrote about them somewhere, sometime ago, in describing how to test individual cells in a flooded lead acid battery.

Title: Re: What is it?
Post by: tecnodave on August 18, 2015, 12:42:04 PM
Vt gets the cigar!


They are used to test the individual cell voltage! The pointed end is placed on the positive end and the side probe is inserted into the cell, the insulator button prevents shorting the plates so you are reading the voltage of the acid. The second cell is tested using both side probes and so on.
There will be a voltage offset on the first cell as follows:

Positive to first cell.               1.05 volt   !
First cell to second cell.          2.1   volt
Second cell to third cell          2.1   volt
Third cell to negative term.     1.05 volt
           Battery total.              6.3  volt

These were made by Sun Electric to use with an automovitive system. They plug into the VAT-28 generator/alternator/battery tester

I use them with a Snap-On VAT-40 analyzer.......8" high sensivity voltmeter and ammeter to evaluate batteries. These will show any variation in cell volts and used with a hydrometer provide a clear picture of battery capacity and probable life span

I bought a used set of Rolls Surette S-530 L-16 for $20. Headed to the scrap yard, they are now at full 400 ah capacity! All cells are at 1.265.  Not a bad use for a tool thought obsolete!  Did it with a kid in total manual mode! Doing sets every 30 minutes and walking the charge cycle at every step
Even doing the eq in bulk MPPT mode and setting the exact voltage and amperage I wanted at that moment..........I know , that is not how the kid was meant to be used but as a beta tester I will do stuff not in the books

Note, the Surette's were scrapped due to blown FET's in the C-40 controller. I bought the whole system as scrap.........Ah the power of diagnosis!

I can truthfully say it's not an AM/FM tuner, although it could be under certain circumstances. Right book, right chapter....wrong page. :) 5 digit display is correct. :) The original IBM PC keyboard used an 8048 microcontroller, as did some Korg and Roland synthesizers. But not a KB or Synth. boB and Mike are close enough to the fire to get their fingers very warm.....Hmmmm.....

A SIG or Air quality alert box for decoding alerts broadcast on AM/FM broadcast

I remember large industries having to have such decoding radios in the greater L.A. Basin about that time.  Air quality board could issue SIG alerts requiring certain industries to shut down. Also used for very heavy power users at peak power times to command a shutdown.

Yes Ryan has it  - was going from transformer to breakers.

Anyone want to take a guess at  the volt and amp ratings for it ?  Each copper conductor is about 1/4" thick by 2 inches .

Two different ratings for if it is mounted horizontally  like in the photo - or if it was mounted vertically instead.
Hint - the difference in those ratings is 250amps .

high voltage flyback transformer, and maybe a voltage doubler circuit with it.

Odd, no large caps visible, no high amp wiring.  hard to figure the end use, not high enough for a CRT.  Maybe for a image multiplier tube, but there are easier ways to get their HV.  the coarse winding on the right looks like it could be for tesla coil, but that would be really HV.   Maybe a high end photo flash, but no big cap for it.

That big coil I ~think~ is a current transformer.  I also think I see what might be a  spark gap inside heat shrink.
Not sure why a current transformer would be doing with a high voltage transformer though ?

Looks like maybe another sensor in there too in-between the coil and HV circuit ?

TJ,  you SURE I'm not excluded from this one ? I had to check my text twice !

This MIGHT be one of your trick questions and if so might be from some strange welder of yours.

BUT it looks very reminiscent of a television (PAL or NTSC ?) vertical interval or, if not to scale, a color burst on the left side followed by a horizontal sync tip and then a line of video followed by more sync and video but I don't see more color bursts.

Or maybe it is teletext ?

You are correct on the "type" of waveform, video. But the "trick" part is what does it represent? It is a legitimate waveform, and getting closer as you read this.  :)

Post by: boB on March 21, 2016, 04:41:57 PM
Well, since I don't see color bursts on the back porches of the horizontal lines on the right, it looks
to me like a single line of repeating info or white to  black to white (or moire pattern, etc) on the left followed by video lines which I can't tell what they are except for some random-ish luminance information for the start of a displayed screen.

Might be the first few lines (less equalizing pulses) of the vertical interval of  a screen.

I thought "text" at one point but text would be more "rectangular" because its' digital.
Looks like regular old video to me.  But that video on the left shaped like triangle waves is
what is stumping me at the moment.  However, the after the triangles, it goes to a gray-scale
value it looks like since the successive "video" or whatever goes below that line.
The back-porch just before the sync-tips arer is where the color burst would be, I think.
EXCEPT that the color burst is on a front porch, not a back porch.  Maybe it's backwards ?

If I saw a color burst on a porch then I would say that the triangle wave and then the short piece of
gray might be a portion of a color bar reference during vertical interval but no burst and weirdly
placed porch stumps me !

Maybe it's from an old video game ?  TV oscilloscope ?

Is this waveform RS-170A compatible ?

They DO use a single frequency during the start of a line for a "run in clock" to
sync the data that comes up after that within the line and I suppose it could
be part of a line and the data afterwards, but that clock is supposed to be
a sine-wave not a triangle wave and the succeeding lines  like like they contain
plain old video.

Not sure  if that is anything I've seen from Leave it To Beaver though ?

I did not have quite enough information to get that full picture.   And, there
was no color burst so am not sure what portion of the picture that was except
maybe the vertical interval which can not have that sometimes  UNLESS, maybe
your capture was severely bandwidth limited in which case only the chrominance
or low frequency luminance would be visible.  But the picture is obviously color.

The bottom-left looks like a vectorscope display, suggesting several colour bars (roughly equal length lines at roughly the same angle from each other - perhaps 10 colourbars?), plus a few other pure-colour areas.

Of course, Ross W's idea of a laserdisc is kind of plausible but I'll go with the train concept.

At least a position sensor because of the quadrant enumerators  -I,  I,   II,   etc...

Well actually a TX Linear but hey! Close enough. :) Slow project on the back burner. Found it this way...needs a total rewire as the "lamp cord" has gotta go!

A pair of MRF 154 RF Mosfets rated for 2MHz-100MHz. I'll be running it 1.8-30MHz. 1.2KW. :) 50VDC supply. Cabinet is a bit on the small side...might have to go bigger!

One pictured is not mine. I do have one in very close condition though. Along with the matching speaker. Works great! Soft warm sound much easier on the ears compared to modern solid state receivers. Long long overdue for recapping. Everything is original from 1938 but the old wax paper caps need to go before they "pop" on their own!

Speaker shown here is mine. :)

Here's my version of it.
It's 3 lumps of decent pipe I think about 1", a piece of 1/4" plate 2" wide. Welded two pipes to the plate side-by-side, drilled, tapped, used some high-tensile (fine pitch) bolts, welded handles on, and a 3rd piece of pipe that sits "inside" the grove made by the first two.

(http://house.albury.net.au/06dec2015/IMG_2155.jpg)

In use, it doesn't damage the mesh or pull on the verticals, and lets me get lots more tension than the hook style.

I'd say a ladle for smaller quantities of metals for casting.  Gold?  Silver?  For a bullet it would only be for one or two, not a batch.

#3 is a switch and resistor.  Which makes me think dash light dimmer, but that would be tied to headlights, not it's own switch.   So maybe a intermittent windshield wiper controller? 

#1 & 2 make me think of a reverb spring, so maybe it's a audio gadget.  I don't know how many cars had reverb units in them.

So for nothing better, I'll go Reverb.

Winner! Winner! Chicken Dinner!

Audio Reverb unit out of a 1965 Plymouth Satellite I owned in the late 70's early 80's. It actually worked fairly well as I recall. Plymouth long gone but I removed the reverb and kept it for hysterical insignificance. :)

I'd have thought that road vibration would have really messed up the reverb effect, but i guess if you are parked it's OK.

Nope. Worked great on the road. The 4 small mounting springs and the foam blocks dampened anything but the nastiest bumps. Even those I don't remember being an issue.

Reverb did actually cross my mind from one of the pictures cuz it looked kind of like a reverb tank in there.  I guess it was !

But what threw me was, 1) the switch.  Why such a big switch to turn on and off a reverb and 2) the TO-3 transistor.

a bank of power transistors on a heat spreader, that may attach to a heat sink underneath
not much visible in the way of IO connectors, 6 pin inline, and only 2 lugs for larger wires visible. Must be more ...
a couple big capacitors
3 big relays (where are their IO connections ? )
lots of discrete parts (transistors, chip resistors & chip caps)
Could be anything that handles some power and steering.

Ok, overhead shot of the board. On the left is the one in question from around 2017 if I'm reading the chip date codes correctly. The board on the right is an older version of it dated May 1994. Just a few minor changes....:)
