    Also musst du eins machen. Ozonwasser ist groartig.

    Useful thing to make from a stepper motor...

    Need two smoothing caps and two bridge rectifiers. Wire the two main coils in series after rectification and add a smoothing cap to each to double the voltage.
    Will give give about 20W . Enough for some proper LED's.

    Thanks for the post, heard about it but so far avoided it due to the amount of time i am going to spend if i get started on this.
    Its super exiting to see material sciences falling into place. It becoming possible to construct the things scientist was dreaming about.
    They knew that Li batteries was inefficient for what they could produce for years.

    Re: Electronics

    I love this kind of stuff and always think about what I could use the motors, etc when I'm throwing out a machine. Never have the time to try and experiment with any of these parts.

    I just got back into building electronic kits found online. AM/FM radio, mini LED Xmas tree, calculator, etc.

    I built several Heathkits years ago when they were in business, 3 TV's, stereos, etc. I loved Heathkit and their unbuilt kits are worth a lot of money now. Nothing like the feeling you get when you turn on something you built and it actually works.

    The below videos show fully visible factual undeniable vortex function of the magnetic fields of the universe.

    The gentlemen in the above video series is stating the actual operational facts of physical reality, from the micro to the macro. The guy is so close to knowing the real truth its uncanny, his observations are just shy of the full facts.

    Re: Electronics

    I'm looking for a good supply source for motion control items.
    I would like to start building my laser an router CNC machine.
    Its just a normal X,Y,Z gantry system. 1200x1200 or there abouts.

    Off the top of my head I'm looking for the following parts.:

    ---------------- Parts List -------------------
    3 x Nema 23, 34 hybrid stepper motors.
    3 x by stepper driver IC boards.
    3 x 8amp power supplies for stepper motors
    1 x PC breakout controller IC board with USB or ethernet interfacing.
    1 x Mach4 or TurboCAD software to suite PC breakout IC board.
    4x 1200mm linear rails an flat linear bearings.
    2x 20dia x 300 s/s rails an liner bearings.
    1 x 300mm leadsrew and lead bearing....
    2 x Bearings to suit 20dia leadscrew.
    1 x Laser head an Spindle motor.
    .
    .
    .
    etc....

    I'm looking at Importing the above items, but they want to much for each separate item $1200. Its cheaper to buy a whole machine ready made $600. The ready-made machine is bench top in size. I could buy the ready-made machine and use it as parts to build the bigger size machine.
