Thank you!

I don't know if my circuit can be classified as a fly back system.
The hall sensor is triggered by a small magnet in the rotor to open the transistor in order to current pass through 2 two coils that will oppose the magnetic flux.
It's simple and effective.

looking good! the best thing is trying something new!  im still in a world of hurt, things just are not working for me. but i keep pushing ! :) ~Russ

Mine is a little behind schedule, but I got it running in the first approach.

I didn't measure the efficiency of the system yet.

Hope u guys enjoy!

the intro (26sec) is excluded....
so 3mins is totally belong to you.
still not enough time?

Ill try and edit some small parts out of the video so i can do 2 slides on the principle and the schematic.
think it will fit but gonna be hard hehehe

Hi All,

I have been putting together a playlist for all of the pmbo 2016 entries/updates.  If I've missed an entry or update video please let me know so I can add it.  https://www.youtube.com/playlist?list=PL4iGRzW04DY0PTZxIe8YKkwj_Z5ZUHqZG

Everyone is doing great work! :thumbsup2:
Just drove to work with mine running in the front window of the car.  Nearly made it all the way as it stopped when pulling into the driveway.  The last block was all shade. :cool:

Mnsman,
Great Job for making effort to compile it into a list!!!
i think more submission is coming in this few days
so hopefully keeping it updated list until the competition end

AcidByte
interesting design
just to highlight that your video is more than 3.26 mins length...
not sure will they accept or not...

to others,
it is fun building a Pulse Motor,
please submit early,
just incase...
u know....
anything could happen when you try to submit/upload....

GOOD LUCK!!!

when i get time i'll try and cut some more off.
somehow my computer doesnt like video editing. :)
thanks for the warning!

** used another computer/ cut some time of the 2 slides at the end. 3 minute 23 seconds with intro :)
reuploading!

it stops alloy :(
last week i was shuffling 1 amp back and forth.
24 hour run took the battery's down 1 volt (from 12.8 to 11.8)
all 4 batterys in parallel drawing 1 amp it was going down way faster.
so it is pretty efficient i guess.

this tesla switch i will be expirimenting alot more with from now on.
next stop is building a 6 switch 3 rotor commutator to get rid of the switching and diode losses. (this is the way to do it good)
it should be possible to reach the same effect with transistors but is a pain in the head to do so hehehe.
circuit should be tuned as close as possible to the charge/discharge rate the battery's like. (you might know battery's have there own resonant frequency).
once your on that resonant frequency it should stack electrons on the battery terminals like crazy.
but i could'nt get enough speed in the motor to get to that frequency.
this motor now tops at 175 hz switching speed. (rotor has 5 x north and 5x south magnets wich comes down to 35 RPS or 2100 RPM).

i read about some company have tried testing this principle aswell. and they said reaching above 400hz will give amazing power.
although they had succes i find it rather hard to get anywhere close to amazing power.
it just runs the battery's down wich i believe is due to the losses caused by the 6 transistors and 10 diodes in the system.
I wont give up just yet though hhehe

good stuff guys,

its getting close! i worked for like 4 hrs last night only to pain painstakingly wait for glue to dry and being impatient and breaking stuff lol

so at about 1am i let it dry... will see if i can finish it today! i sure hope so.

6 days left but ill be gone to the BEM over the weekend so i have like till Thursday!!! ouch!

making a video today so all is aware to make sure if your entering the contest that you post your final video in the final video thread...

good luck everyone! and its been cool to see  the hard work so far!

hi,

i do agree with high frequency and high voltage...
i do have a DIY generator with 36pole alt magnet at 600rpm...
the giving me impressive result...more exploration on that,
once done...will upload it in youtube.

commutator may cause higher friction...
can try use LDR as sensor ?(just a suggestion)
or keep the energy in capacitor 1st,
then divert it into 2channel (C1 to coil, C2 to battery , if extra)
i noob in the battery charging stuff...so i have no idea about it....

Good LUCK

i have some variations of the circuit aswell as a 555 controlled version.
i think i could figure something out using ldr's instead of trigger coils
got to make some changes to the rotor to make that posible.
i think i can shine a led under the rotor and cut drill some holes in the hdd disk (as the rotor is basicly sitting on the original aluminum hdd disk everything is still there).
then modify the casing a bit to place the ldr's underneath :)

also the principle uses a load of 0.8 ohms.
wich is almost like battery impedance.
maybe i can modify my 8 filer bedini coil to run from the bridge.
got to get some bigger transistors though
so tells me to match the load to that impedance and maybe this will already give some desired effects :)
gonna have a lot of expiriments with this one to come hehehe

the upside of the commutator would be hard on and hard off switching.
so no loss on diodes and transistors :)
some people i talked to about this principle all say commutator is the way to go.

would be a nice first print from the 3d printer i will be orderring

This is quick video preview of what I'm building. It's kind of a Window Motor on steroids.

One drive coil and 3 generator coils, if all goes well and get it made in time.
