    Ortho,

    not sure I am ready to learn another program, still working on learning 123D design. it spits out an STL file... I have 3 slicers, slice3r, cura and matter slice, matter slice is the one that is making it sawtoothed. just got my tricklazer carbon fiber arms in today, so the machine comes apart and gets new delta arms and an LED light ring. my purpose originally for buying this thing was to do a window motor frame and make some genny coil spools and make hall sensor brackets and timing discs I could offer everyone here on the forum. those are the hardest parts to get... and a printed timing disc would hold the tiny rectangle neo mags perfectly and make window motors easier to build for everyone.

    perhaps we can collaborate on the drawings as that is my weak spot right now. if you are up to it we can start a new thread on 3D printed SG parts..

    I would say the device I have been enjoying the most is the Tesla Switch and the DVD it came on. you can do a screen capture, make the circuit board and have a running Circuit in no time. it works on a small scale. I found matched transistors really do help.

    a pic or arduino version would be more stable that an SG3524 version, I went thru 3 of them before I found one that worked correctly on both sides. JB has already told me it can be done with a pic chip, just trying to find the time to learn pic.

    I have been concentrating on my 3D printer for the last few weeks. learning 123D design, and relearning Gcode, which is what the printer uses, I learned it in my CNC machining days, a long time ago but the commands have not changed, they are slowly rising from the mist of my memory... I have a Delta printer so the X and Y go both ways pos and neg, you can have a code like G28 Z2 X100 -Y50 F5000 where Z zero is the print surface, there is no z negative, which is opposite most metal cnc programming...... and right now the radius steps are too big, need to get a different slicer program. currently all the arcs on my prints look a bit sawtoothed.


    anyway good to have you back you guys inspire me!! there are so many great experimenters here, one day I hope to meet all of you.

    Hey Tom. You're right the Tesla Switch is fun. I have one working on a PIC. Ran for a week before the batteries dropped below 12.0v. Will post details on the TS thread

    Hi Tom...I used to do a little gcode on a jewelers lathe....it's like programming in assembly language. Very powerful but so many lines of code!

    I did a test last night in openscad to see the difference with smoothing on and smoothing off to see the difference in the gcode produced by a slicer.

    The code for smoothing everything in the file is: $fn = 100;
    The part made was a simple cylinder and the code for that is: cylinder(r = 10, h = 5);
    That creates a cylinder with a radius of 10mm and a height or thickness of 5mm.

    With smoothing turned on the gcode was double in size. I looked at it using WinDiff and it is all about the every line of code you make a move with.

    If you use anything that can export .CSG (constructive solid geometry) files, openscad can import it and the smoothing command can be added to the beginning of the file.

    Don't know if this will help you now but perhaps in the future. Openscad is very easy to learn compared to gcode and it comes with example files you can load and examine each line and see quite easily what it does. I would say that among all the programming languages I know and have used, this on is by far the simplest. There is no type checking whatsoever...it is very straightforward and produces exact and beautiful results.

    Hello Tom, I've been resisting temptation on that printer thing. I still have a few computers laying around that have AutoCAD. SmartCam, and Solid Works on them. It's been probably two decades since I generated code from any of it though. The tesla switch sounds interesting but I'm working with Les Kraut right now trying to learn about Tesla coils. Since people started using the Slayer exciter type circuits it's really easy to get these things working. I even had some interesting results from running the Tesla coil setup from the stator motor and SSG circuit. I'm running my window motor from an AV plug receiving energy transmitted from the coil. I could probably post that video here since it's a window motor project. I'll talk to you guys later.

    Hello Tom,
    It's good to hear from you. It's also nice to be around old friends. I just wanted to say hello and see if I could get some inspirations or new ideas.
    Tanks Tom

    for any newbies, that's sarcasm. Dadhav has millions of views!

    My transparent motorcycle alum battery has finally settled to about 12V on the high side (that's right after a charge) and normally rests around 11.5 pretty cool no acid :-)

    Kind regards - Patrick A.
    Hi Patrick
    My battery was badly damaged before I converted it and wouldn't hold a charge. I use it all the time now. Mine doesn't have the power or capacity of a fresh new LAB but you probably noticed the impedance is really different from the LAB. I find that my motors and circuits with higher winds run much better with the alum battery.
    Take care.

    I just found this: http://www.energyscienceforum.com/at...9&d=1409348374 posted by you in the ferris wheel thread

    So I see that in the ferris wheel when the hub motor part is off there is no battery seen by the circuit,… and the problem that I have is that when the cap feeding my bedini-cole circuit is below the volts generated by the power coil the energy flows back through the transistors, so I just need a switch to isolate the cap until its voltage is higher than the generated by the power coils, and let it fire there like a big punch.

    Maybe the comparator cap dump circuit can do the job... SSG --> comparator --> bedini-cole -- > some thing else

    Tnx for the reply Patrick.

    I will have to find another way of doing this... (And I don't want to use relays...)

    just think of them as diodes not transistors.
    The same thing will happen with the SSG.

    Hello Guy, Patrick, Friends
    Funny you ask about the window motors. I couldn't think of any more ways to run my motors until the other day. I managed to run my steel rotor motor wirelessly from a Tesla coil. Well I add a ground if I want to get the best run. I run the coil from the alum motorcycle battery and use the Slayer exciter circuit for the coil. I'm running at about 11 volts and can get about 4-6 feet away from the coil with a one foot long antenna on the AV plug for running the half wave circuit for the window motor. I haven't been doing very much other than getting caught up on things that I've neglected over the last few years. Oh Ya, recovery from taking a beating on the UFO forum is still taking time too. Ha, LOL. I'll probably have a video posted next week if you're interested.
    Nice talking to you guys again.

    I have an issue with the idea about running a ssg circuit, and send the recovery to a cap that would be the source for a bedini-cole circuit in the same rotor.

    The SSG circuit in radiant mode tuned to 1 pulse per magnet would give me a RPM of aprox 3200. but with the secondary circuit in place (bedini-cole) the RPM went down to 2000+ , so I started to try things to see what was causing the RPM loss... After some tests, it seems that the bedini-cole circuit is causing drag even if it is not triggered, is that normal???
    Yes.

    Originally posted by AlvaroHN View Post
    I connected the SSG circuit to run the rotor and the output of the ssg was sent to a comparator. Then I placed again the bedini-cole circuit with an empty cap as power source and the drag started again, there is power been sent to the primary of the bedini-cole when the rotor is spinning, by normal induction (the output of the bedini-cole was not connected to anything) I don't know why this is happening since the power coil is isolated from the power source (empty cap) by the 2 transistors. Could this be happening because of the reverse breakdown of the transistors???

    Any advice?
