The compass motor is balanced fairly well so it doesn't make to many waves. When the kicker servo swings out the weight the centripetal inertia drives the boat to the left of the screen (north). Stay tuned:)

Magnetic inertial thrust is demonstrated in this video. The magnet spins the armature of the motor when turned by a separate small electric motor in phase with Earth's magnetic field. A servo swings a weight out and back at the same point in the rotation distancing the center of mass from the center of compass torque. Stay tuned:)

The armature of this statorless motor or compass motor is made of acrylic. Acrylic is a little challenging to work with so it was a learning curve. Gorilla Super glue was used to bond the acrylic parts and they were cut with a razor saw. The holes in the disc were drilled with a special bit made for acrylic. A hand drill was used but a pocket jig with some clamps was used to keep the holes straight. Please subscribe. Stay tuned:) Tips appreciated: https://gofund.me/dc5c9c1d

The whole motor turns around the powerful magnet while the magnet stays pointing north. Stay tuned:)

This is the best one yet. It uses 16 @ 3/4 inch diameter by 1/4 inch N52 neo magnets and has bearings. Wow! It didn't seem possible at first but is pretty fast at 160 RPM. Also it is scalable. It goes faster with bigger magnets. Stay tuned:)

Not exactly efficient or free energy but pretty cool this neodymium magnet motor relies on the Earth and a small electric motor to spin the magnets. Stay tuned:)

It does 130 RPM top speed and looks looks more like a motor now. It still wobbles because the armature is a little out of balance so that is something to improve in the future. Stay tuned:)

If you are into electronics kits and you haven't tried out basic surface mounts you are missing all the fun. It may look daunting at first but with flux and a little practice you can do it. As you may notice in the video getting the QFP44's lined up perfectly is very important and worth taking your time with until they are just so. Also pay attention to the orientation/polarity of the component placement. What the video doesn't show is that we put one of the QFP44's on facing the wrong direction, removed it (with a soldering iron trick) and soldered it back in place correctly. Stay tuned:)

The magnet is a powerful compass that can make the boat turn! The compass stay pointing North while the electric motor rotates! #physics #magnet #torque #spin #experiment

Practice, practice, practice... Stay tuned:)

The first patent for the gyrocompass was in 1885. How did they keep this quiet for so long? Stay tuned:)

"Practice makes perfect." Well better at least. I have come a long way and still learning. My first TH soldering kit about 4 years ago didn't work and now I am doing SMD soldering! Lessons learned: 1) use flux more often 2) take frequent breaks only doing a few components at a time 3) use thin solder 4) apply tip of soldering iron to pad long enough to let the solder flow onto the component without overheating the component. 5) use less solder Stay tuned:)

Just another SMD easier kit with Thru Hole also soldering build. Stay tuned:)

A nice kit with a quality PCB. It's a great toy once it's assembled. The LEDs and resistors are 3mm and the pads on the PCB are small at about 1.5mm and also pre-tinned. We are trying to solder under a microscope and it is taking some getting used to. Our hands normally don't shake quite this much but are extended toward the position where the microscope ends up. We will have to adjust this so the forearms can be almost parallel to the chest and get steadier results. Stay tuned:)

It's hard to find an inexpensive electric gyroscope so the investment in the Gyrobot toy many years ago seems to have some additional value. The top of the armature is attached to the wooden hoop with a fishing swivel so it is free to rotate. In effect the motor pushes against the gyroscope and make the whole thing turn. Stay tuned:)

This is a good beginner to intermediate soldering kit. In this video, part 2, the main PCB is assembled and the lamp assembly is completed. Stay tuned:)

Some fun with the Magnetic Levitator toy. There are some possibilities with the pendulum such as making it longer or designing it such that it was in the center of the levitator to eliminate wobble. Also it swings for a number more minutes if started from a higher angle. Consider that a pendulum is very much like a gyroscope in that it will tend to swing in one plane. Stay tuned:)

Learning how to solder and check work with a microscope. Stay tuned:)

Plugable Digital Microscope works well with Android tablet and USB OTG connector. I will be using it in soldering. Use cameraFi2 app from playstore and you should have no trouble. The stand is good quality and holds microscope in place well. I have had the suction cup attached for days now without it coming loose. Stay tuned.

There are fishing swivels as bearings on the top and the bottom of the armature holding it to the wooden hoop. Some friction from the rotating armature through the bearings/swivels makes the boat turn a little bit but not nearly as fast as the statorless motor turns and it could be counteracted by a number of methods in theory. But we'll cross that bridge when we get to it. For now we see an Earth magnetic field permanent magnet statorless motor propelling a little aluminum pan boat at about 2-3 inches per minute South. (And the direction can be changed by repositioning the weight and altering the timing on the statorless motor) This is pretty amazing in my book. Stay tuned:)

Arduino Nano digital pin 3 isn't always PWM on knock off brands so was the case with this. After rewiring to digital pin 5 PWM worked but not well with the boost converter. So at 5 volts the maximum speed the N20 motor will turn the magnets is 300RPM and that is what it does in this video. But it runs so much more smoothly and quietly than it did before where it was using a method of starting and stopping the motor in the sketch/program for short intervals. It will still do 300 RPM with 4 less of the N42 half inch diameter neo magnets. Stay tuned:)

We get the Earth Field Permanent Magnet Statorless Motor to turn 400 RPM. The n20 gear motor we are using to turn the magnet cannot go faster than that under load. Stay tuned:)

Earth field permanent magnet statorless motor. It gets up to 360 RPM with some more magnets added to the stack. Now the magnet bouncing up and down becomes a problem. The magnet jumps because the Earth's magnetic north is at an angle down. Stay tuned:)
