Quantified Backlash Drive for the PIE

The PIE.xx or PIExx is the newest iteration of the original PIE which was based on the work of Roy Thornson. This build is using the masses, or weights, from the PIE 4 series as they are the most advanced masses built to date with their “dead-blow” properties. It is using the “stacked” or “double-decker” design of the PIE 2 series for the smaller footprint and for the implementation of some new features. It is using the non-contact switches from the PIE 4 series as they are simple and inexpensive to interface with multiple speed controller designs.

The newest and most radical feature added to the mix is one I am calling the “Quantified Backlash Drive” or QBD.

The QBD: The QBD is a 2 input/output “jackshaft” that allows partial uncoupling of the two while ensuring the uncoupled halves stay within a specified range or have a specific backlash between them. The entire purpose of this is to allow the two rotating assemblies (“wheels”) to use separate drive motors each with its own separate SDC but not allow the two wheels to get out of their approximate 90 degree synchronized relative positions.

Premise: The need for the QBD stems from wanting to have additional pulses per revolution (ppr) which will make the end-user feel less pulsations because they are much closer together. Previous attempts at having more than 2 ppr yielded no stand-alone thrust. Using 4 ppr, thrust was measured as an aid to propulsion for a vehicle with a large enough mass to absorb much of the pulsations. When dropping the ppr to 2 ppr, self-propulsion was achieved without the need for as much overall vehicle mass. Note: Some overall mass is still required to absorb reversion pulses.

The reason for the lack of self-propulsion is the interaction of pulses and the requirements of the SDCs. The SDCs add more than a speed boost through part of each rotation, they add a momentary deceleration when the mass nears apex causing the mass to impact its stop with much more force. This is incredibly important and cannot be done if there are other masses needing to accelerate at the same time. This makes the SDC combined with the QBD a truly operational “acceleration and deceleration” mechanism!

The new Quantified Backlash Drive being set up.

The SDC & QBD Ready for Testing.

NEW PIE 6.0

As I have been posting here, I have been building the Trammel engine for over 2 years now. I have had some successes, and some failures, and right now I have to admit that I am a little “stuck”. In order to “pull back” a bit and shift focus slightly to a new PIE. The PIE 6.0 is using a lot of knowledge gained from building the Trammel. As before, the PIE 6.0 will be another “open source” project, so, here we go…

March 30, 2024 was the beginning of the PIE 6.0. The 6.0is bringing together multiple working designs of PIE, some of the parts reclaimed from earlier builds, and multiple bits of knowledge gained from the Trammel engine project.

The similarities: The 6.0 is using “dead-blow” weights, we need to refer to as “active masses”, and it is using the stacked “double-decker” design of the PIE 2 series. It will also be using the powerful little brush-type motor(s), speed controller(s), and SDCs (Speed Differential Controls).

The Differences: The 6.0 is planned to be using 2 motors and drive assemblies, one for each disc (“disc” is a more accurate description than “wheel”). There is a planned timing mechanism that will keep the discs working together while allowing them to also utilize the flexibility of the independent motors and SDCs. There is also a proposed frame pivot assembly, to be explained later.

The Need for Changes: The PIE design is a good example of something that works, but it isn’t readily accepted to be used “as-is” due to the prolific “pulsing” it produces. Previous efforts to improve the “feel” of thrust produced fell short of that goal, so efficiency and “harshness reduction” are the primary goals. There is still going to be noise, I am not focusing on that right now as it is much easier to control with simple modifications to gear designs and sound-deadening covers (hoods).

Stay tuned, we have a lot happening very quickly now, photos below!

PIE 5.0 Update & “Scientific Heresy”

The PIE 5.0 does work! It is not as good as I was hoping, but it does show just one more way this “impossible” propulsion becomes possible! The things learned by actually putting hands to work in the shop far outweigh the mainstream physics falsehoods still perpetrated in many (or most) of our “higher learning” institutions.

What I am about to say is considered “heresy” in the “religion of science”:

Science is supposed to be available to everyone.

Science is supposed to be FUN.

Scientific information is supposed to be openly available and shareable.

Science and physics are supposed to be shared and debatable among all of us, not just the PhD’s. PhD’s who unfortunately tend to believe what they were taught in their final years of education, which is that their Graduate Degree somehow makes them “better” than everyone else. Science is not supposed to discriminate, science (by definition) is to “observe” with an open mind, not “dismiss” with no regard to the idea of actually learning what is possible.

That said, the PIE 5.0 did work, but just not as well as I hoped but that is actually a large part of what makes testing it successful! Every test, every build, every experiment, every failure, every debate & every argument lost has taught me something and makes me who I am today!

Latest Test of the PIE 5.0

The data and understanding gained from development of all of the PIE versions (including the PIE 5.0) is now being poured liberally back into the Trammel Engine project with a renewed enthusiasm! That alone is worth the time spent planning, laying out, building, and testing! And as a bonus, it is “fun“!

More to come soon, please check back here for updates!

PIE 5.0 Becoming a Reality & 1st Picture

So the first successful test of the PIE 5.0 concept is in the books! Although it is only a bench test with one “wheel”, built on the PIE 4’s frame, and sitting on roll pipes, there is no doubt that there is strong forward thrust with reversion at a level of “little to none”.

Adding more weight will definitely increase thrust as seen in experiments completed. An increase of RPM may also increase thrust, but that has not been experimentally confirmed.

So, what is the big deal with the PIE 5.0? No sun gear! No planetary gears! No impact zones! No stops to get broken!

What does this serve to accomplish? Less noise! Less potentially damaging pounding! Longer thrust pulse duration! No need for a pivot point to swing the weight! Virtually no reversion!

The one thing I struggle with is the need to make this work public while also wanting to build a business around it. Conventional thought says that it needs to remain secret, while every fiber of my being screams “make it public”. With guidance from above, I have built this, & with that same guidance will come the reveal.

Below is a photo of the first tested prototype. Much continues to change so more details will be added as work progresses.

Updated Website & Upcoming PIE 5.0

11/9/2022

It has been a long summer of trying to balance my time in my workshop/lab and my career as a Parts Associate, now promoted to Supervisor. Sometimes I think that I must be doing a good job, but there are some difficult days when I think that I am the supervisor because nobody else wants the headaches…

Trammel Update: The Trammel Engine has been rebuilt over and over and now 99% of the internal motion is now working as expected. There are internal components I call con-rods (connecting rods) which only pull and never push, then there are push-rods which can only push and cannot pull. The con-rods are now of a very strong design and their length is adjustable. We had multiple con-rod failures until this design was implemented.

The problem appears to be with the push rods. It was originally thought that their purpose was more of “timing” between the lower halves of the motor, so they would only need to basically “take up slack” with a spring load. This now appears to be incorrect. It seems that they must actually provide a “hard stop” which only pushes but cannot pull. Springs will still be used, but more as an ant- rattling device (I think).

The constant trial runs and failures precipitating rebuilds and repairs have really taken their toll on me mentally… I need a freakin’ win for crying out loud! So I am now (on an opposite workbench) building a PIE 5.0! It is a culmination of PIE and Trammel knowledge gained over the last 3 years and preliminary tests are incredibly promising.

It is still an ugly “Frankenstein” of a machine, but I will post pictures as it becomes something to look at! The good news is that even though it is still in the earliest stage of development it is already making pounds of thrust (too bad NASA)! With one wheel! With one weight!

Sorry I don’t have pics yet of the PIE 5.0…

Our web site (http://stclairtech.tech) is revamped and rebuilt with new fresh graphics and a much nicer interface which is easy to navigate. I also have a page showing some pictures of UAPs (UFOs) over the St. Lawrence River on the US & Canadian border. The pics show black, odd-shaped objects in the air which might be explained away as birds or insects, but they are 100% real photos of objects which only show up on the digital camera! These are completely invisible to the naked eye! See these photos here: http://stclairtech.tech/UAPs/

Thanks for reading and following along… Talk to you again soon!

Trammel Testing, APEC, PIE Mini

It has been MONTHS since I updated here… A lot has happened in my life and in the shop! For those interested, I have switched gears in my professional life. Since the change is quite dramatic, I have been under some stress “getting in the groove”, but it is a needed change and I’m getting it all figured out.

The PIE X aka Trammel Engine is coming along. Inside it (still not ready to reveal too many details) are some components which were made too weak, but they have been rebuilt and replaced with much more robust pieces! I have experienced some intermittent thrust and have kept moving forward with this as much as possible. I also recently received a much-improved motor and speed controller which is now installed.

A Look at the New Motor
First Run Test

It has become quite evident that as I contact potential business partners and investors, I need a small and lightweight demonstration model which can be taken along to those meetings. With that in mind, I introduce the “PIE Mini”. The PIE Mini is a nearly complete, single weight, working, demo model which is really small and light with plastic gears and a hollow tube instead of a large “wheel”. It’s power source is a super cheap cordless screwdriver from Harbor Freight. Although it is intended to be a portable demonstration device.

I believe it will also be a design which could become the first model of a sellable working model for science minded people everywhere to experiment with.

There are a couple of videos of the PIE Mini on BitChute .

First Test on Wheels

I have also now run a live demo of the Mini at the APEC conference on Feb. 27, 2022. During this presentation I showed that the unit actually needs mass to operate and that is really it’s only environmental prerequisite. I should be posting that presentation on my BitChute and YouTube channels very soon. Until then, here is a link to it on the American Antigravity YouTube channel.

Part 1
Part 2

I want to thank Ross Small for joining the video conference with a presentation of his own. He is building a “linear thrust” machine in the hopes that it will be a helpful learning aid for everyone to better understand the mechanism of inertial propulsion. Some of those very principals are integral to the Trammel Engine, and have also got me thinking about other, future, design builds.

PIE X Gets a New Name – “The Trammel Engine”

November was a very busy month for Stclairtech R&D, and for the PIE X project!  

Ready For “Public” Testing

So much has been accomplished with the PIE X project it is mind boggling!!! The “backfire” issue has been resolved and there have been some very successful tests completed running with the electric motor.

Some of the highlights are:

The “backfire” problem is now well controlled with a minor design workaround. Future builds will take these backfire control requirements into account so that “workarounds” will be unnecessary.

The PIE X has earned itself a name of its own and is now known as the “Trammel Engine”. It is a name which is both literal and figurative. Literal because it has internals which resemble the operation of an ellipsograph, or “Trammel of Archimedes”, and is a figurative tongue-in-cheek reference to the same machine’s moniker of being a “do-nothing machine” since its purpose seemed nonsensical for the most part.

 The Trammel Engine (T-Engine or TE for short) is now running well enough to perform some rudimentary testing which has demonstrated true linear thrust. It has been measured thrusting upward with a weight scale with an averaged thrust of .7 lbs. and peaks ten-times that amount running at input speeds of no more than 350 RPM.

Unlike the earlier PIE systems based on Thornson technology the T-Engine does not seem to have a low-speed limitation, and it is creating more thrust as RPMs increase.

A few shareable facts (so far):

1- The TE has externally driven mechanical components which are driven via the electric motor(s) and cause overall rotation along with internal rotating components.

2- There are 3 major rotating component assemblies consisting of metal parts using ball-bearings for friction reduction.

3- Some of the pieces of the internal assemblies can be labeled with names resembling those of internal combustion engines. Pistons, connecting rods, camshaft-like parts, and flywheels are just some of those named components.

Overly simplistically stated, it uses something very similar in function to a lever pulling a load which is allowed to move past apex and “snap over center”. This over center, snapping, rotating assembly is moving masses, accelerating, decelerating, and recovering them 4 times per disc rotation.

The internal timing of these components, and the use of a “camshaft-like” sub-assembly is of utmost importance to eliminating the backfire issue!

There are several videos available on YouTube and BitChute, the latest of them (at this writing) is a 2-part set called “Trammel Engine Works Part 1” and “…Part 2”. Part one shows the test rig, and part two shows a “successful” test which ended abruptly when the fuse blew. It turned out that the fuse blew because one of the “connecting rods” broke. Here are those videos below.

Part 1
Part 2

The broken and damaged parts are now being replaced and repaired, there will be more tests to come very soon! And hopefully more can be revealed soon…

PIE 4.8 Re-Phased and then Switching to Co-Rotating Design Testing (2 Updates)

On 7/31/2021 the counter rotating PIE 4.8 was re-phased to have the planet gears synchronized (self-propulsion mode) but then one plant gear was removed from each wheel so that forward pulses will alternate from on side to the other. The non-functioning weights were fastened to the planet gear mounting holes to help balance the wheels a bit.

Results were very similar to having all the planet gears and weights in place and operational with road testing showing a 4% to 6% reduction of engine load at the standard speed of 55 MPH with little to no headwind.

I believe this poor performance may be due to the counter-rotating wheels. Previous testing has shown better thrust using co-rotational wheels (rotating in the same direction). It has been suggested that counter rotation might be needed for stability, especially in either an air or space (aerospace) vehicle, but co-rotation should be very possible with proper management using either air foils or gyroscopes. Co-rotation should still be quite manageable a with minimum amount of manipulation.

8/10/2021 Update

I have now rerouted the chain on the PIE 4.8 so now the Left and Right wheels both turn clockwise, and I have modified the ramp on one of the RH wheel’s weights for the direction change and timed the wheels for self-propulsion (synchronized). With just one weight on the right wheel and two weights on the left wheel I now see that it is a definite improvement over the counter rotating wheel setup!

The first noticeable difference between counter rotating and co-rotating is when counter rotating in this same configuration of 2 weights on left and one on the right the propulsion pulse was strong when a single weight pulsed and weak when two weights synchronously pulsed. With co-rotating wheels the propulsion pulse is strong when a single weight pulsed and doubles in strength when two weights pulse synchronously. In simple terms, the unit is stronger when co-rotational!

I need to put trolley wheels under it again to test properly on the bench, but the unit seems strong and is pulling itself (sliding forward) across the bench when running even without fine tuning the gear timing. Next, I will adjust the gear timing and modify the other weight for clockwise rotation so that I can complete this round of testing.

If there was lots of extra time to do extensive testing it would be best to build it with 4 wheels, two co-rotating and two countering them to be able to arrange them in different ways to record and study the results. I don’t feel it is necessary at this time as the testing I have done is more than adequate to demonstrate the workability of the PIE system.

I have discussed the origin of the SDC and the subsequent positive effects of its use, and when I was setting up the PIE 4.8 to co-rotate, I could visually see the point of heavier motor load in the PIE’s rotation. So I published a short video of this visually obvious effect demonstrating the position in rotation which needs the RPM boost using the Speed Differential Control (below).

More to come soon!!!

PIE 4.8 Changes to SDC and Issues on Latest Test Drive

New SDC Switch

It has been a very busy several weeks since I have had opportunity to update this blog. Work and life have been very busy and work on the PIE has been slow.

The re-phased PIE 4.8 has had the first road test completed with no SDC as the SDC micro switch is a continuous source of problems. The lever on the switch tends to break or get bent very easily and the roller wheel also tends to fall off frequently, so it was decided to use a “proximity switch” as a non-contact alternative. The switch chosen is a magnetic switch used for building security systems as a door/window open/close sensor. This is easily activated by mounting magnets instead of mechanical actuators and this works very well.

The PIE 4.8 second test drive was, however, less than outstanding. The re-phased PIE wheels and SDC “should” have yielded much better results than the previously phased tests when it was set up for “self-propulsion”, but the results were very disappointing as the engine load reduction was only in the 4% to 6% range.

I believe it has to do with the counter rotation of the wheels. The “zone of thrust” or “thrust zone” on a single wheel is rather wide as it pulls forward through a good 45 degrees of the rotation, by having the counter rotating wheel, the “thrust zone” is effectively narrowed but instead of “focusing” thrust, it only eliminates part of it.

The next steps to calculate the reason for such failure will be to adjust phasing back to synchronous and increase pulse torque by removing one weight from each wheel. The thrust will alternate between the CW and the CCW wheel, this should demonstrate the theory of the wide thrust angle vs. narrowing the zone.

Phased Back and Switched Down to Two Planet Gears

The non-functioning weight is being used as a balance weight. The planet gear that is not being used is removed and the weight is bolted to the wheel in its place which balances the wheels enough to keep it from tearing itself apart.

One Planet Gear Removed and the Weight Used for Balancing Wheel

If this works out, the plan is to reverse the rotation of one of the wheels and repeating tests with co-rotating wheels to increase thrust without narrowing the “thrust zone”.

Ready For Road Test Set #4

On a side note, I believe the thrust zone will automatically be much more condensed (thus stronger) with a different design. Perhaps the PIE X will accomplish this.

July Update: PIE 4.8, APEC Conference Presentation, Coming Soon – “PIE X” –

July Update:

I just realized that I have not updated this blog in a month, things have been pretty busy around here at Stclairtech R&D.

The PIE 4.8 is fully assembled and functional, I have put on an inertial propulsion presentation for the APEC conference, I have had to move part of our R&D lab to a new location, and actual construction of the PIE X is underway.

PIE 4.8 Testing:

The PIE 4.8 is running through a full gamut of tests where many things are being learned. It is also passing every test so far with very few technical problems.

It is installed in a road vehicle at this time. Below is a quick video getting ready to drive.

I have had smooth enough gearing that there has been no issue holding timing adjustments.

The counter rotating wheels has proven quite successful.

A pendulum type test has been performed successfully. I do not agree that this is truly the “gold standard” that agencies like NASA feel it is since it is easily manipulated. I went to great lengths to ensure accuracy, during which I discovered numerous things which could have skewed the results, reinforcing my belief that a more “foolproof” and “accurate” method needs to be developed. If the PIE did not “pulse” the pendulum test would be much more accurate! A video of the swinging pendulum test is below.

The SDC system works equally as well with 4 actuators allowing the 90-degree offset between wheels which works better as a hybrid design.

Test results will be fully posted here as soon as compiled properly!

APEC Conference:

I narrated a Power Point presentation at the APEC conference on June 26th 2021 regarding the PIE inertial propulsion system and its development from the beginning. The presentation covered development, successes, failures, and equally importantly that I am not trying to “prove” anything. My videos, this blog, presentations, in-person demonstrations, and all testing data is not an attempt to “prove” anything but is simply to “demonstrate” what has been found. What works and what doesn’t work, what is worth investigating and what to work around. A link to the APEC Website and to a video recording of the presentation is below.

Alternative Propulsion (APEC) website

Conference video from 06/26/2021. My part starts at about 3:46 but all are very well worth watching!

PIE X:

Although I have certain obligations to withhold some detailed information regarding the PIE X, I do want to touch on it briefly.

The geometric working design (like the Thornson design) has been presented to me as 2nd and 3rd hand information because the originator is “unavailable” (possibly deceased). There is almost no written information about this design, so much of it is being built from photos taken decades ago and drawings, diagrams, and notes from people who have held this information “in trust” for all these years.

A few details that I can share at this time, the PIE X plans will:

Be a chain driven, electric PIE.

Use 3 “wheels” which for this design will be known as “discs”.

Be able to be mounted in virtually any orientation.

Run at a slightly higher RPM.

Have less obvious “pulsing”.

Be built very heavy (sturdy), with experimental use in mind.

Not use (probably) an SDC control circuit.

Will have more moving parts than the earlier PIEs.

Is much more expensive to construct.

At this writing, the 3 discs are machined, welded, matched, and ready for paint and the framework is partially built and is ready for more components to be assembled. Most of the components have been procured but many of them require customization and there is still much to do!

I wish I could say more and share the PIE X build as openly as the previous builds, but it will be exciting to see if it works as we (my collaboration team and I) believe it will, the unit will be unveiled publicly for demonstrations!!

Until then, stay tuned for more info as it is able to be released!
