    Hi! You did good and very powerful bridge, but for the wiper motor, I think that you can put less powerful tranzistory.Ya will collect bridge from what is at hand, the rest shop.Ya asked you a schematic diagram of the bridge, in the photo is not clear where to connect provod.S respect Ivan

    you seems like trying hard in typing ... try again .:thumbs


    With my respect too Ivan ... In the first post, I said that you can use whatever you like N-MOSFET ... and then here provided you with how to change, calculate and to be convinced with your choices ...
    If you can read schismatics "which is in the AN file" ... get what you want from the copper layer .


    And we all use Google translation ... I don't understand these red words ? ... no Google equivalent translations ... Is there any other words can be used ?

    If any of you are having a difficult time remembering the resistor color code and constantly needing to look at a chart here is a tip to help you remember it. Using a catchy sentence whose words first letter corresponds to the first letter for each color in the code is much easier to remember. My electronics instructor was taught electronics by the United States Navy so keep that in mind when I tell you the sentence he taught us in class. You can make up a sentence of you own if you don’t like his but I have not forgotten it in 30 years. He taught us, “[deleted by admin]”. That corresponds to Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Grey, and White. And that corresponds to 0,1,2,3,4,5,6,7,8,9.

    My dear @BlazinH please forget these bad words from your bad teacher ... What if I told you that Google gave me Rude translation words in your post !! :mad: ... Not acceptable please ... and It is a bad thing to live with for 30 years ... that corresponds to nothing but to accept that "[deleted by admin]" as part of OUR concepts of life ...

    Do you know what www means for this site ? Does every one speak English ? Is all members are male ? Is the whole world is following the same stander for every thing ?
    try to give a solution that a close exact mach for every one's WW needs and doesn't offend any one's feelings ... Like, print the picture and cover it it like a credit card in your wallet or add it as a sticker in the back of your DMM ...

    Hey Yobuddy, have you found a local source for the copper disks? I have a sheet of 1/4" copper out in the shop. I could probably run it through the CNC and make half a dozen or so. I am thinking of trying this project out as well (considering the cheap Chinese drivers that I am planning on using for my 6DoF).

    EDIT: By the way, I cleaned up the PDF file generously supplied by Abdo Tahan and created a vector art file suitable for CNC cutting for the copper disks in case anyone else has access to a machine. Here is the vector art file (in EPS let me know if you want it in another format):

    A couple of cnc'ed disks would be great buddy!
    Let me know if you CNC a few buddy!
    thx @Historiker

    Arg...I ran a test run yesterday. I think I need to learn more about milling copper. It was a disaster. The drilling (using Pecking) was fine, but the milling portion had multiple errors. I used settings recommended by various CNC/Milling forums but I must be doing something wrong. I have milled aluminum and brass successfully on the CNC before, I did not think that copper would be so difficult, lol.

    Sorry to get your (and my) hopes up.

    I started ordering parts for Abdo_tahan's h-bridge but I need help

    what is the difference other than price

    MOSFET, N-Channel International Rectifier IRF3205 N-Channel Gehäuseart TO-220AB I (D) 110 AU (DS) 55 V price 3.66 euro

    MOSFET (HEXFET / FETKY) International Rectifier IRF3205Z N-Channel Gehäuseart TO-220AB I (D) 110 AU (DS) 55 V Price 1.73

    I'm a little confused :))

    what do you say

    sincerely,
    postsol

    Nice peace ... I see it is a better version you may use ... Keep up the good efforts ... good job my friend:thumbs

    I'm almost done ...

    Hi every one ...I'm sorry for not having much time reserved for fast forward steps in this version update but I guess you'll understand ... So, 5 days or so I've finished the two boards assembling ... here is the latest pictures ...

    2014-01-16 07.08.51.jpg 2014-01-16 08.04.04.jpg 2014-01-16 14.20.30.jpg 2014-01-16 14.21.19.jpg 2014-01-16 14.22.19.jpg 2014-01-16 14.23.24.jpg 2014-01-16 14.25.24.jpg 2014-01-16 14.25.43.jpg 2014-01-16 14.26.08.jpg 2014-01-16 14.26.25.jpg 2014-01-16 14.26.50.jpg 2014-01-16 14.27.21.jpg images.jpg PCBA-Euro-Type-Screw-Terminal-Block-Connector.jpg Terminal-Block-Flat-Base-Type-PA8H-PA12H-.jpg
    I'm going to use this kind of white terminals to firmly tight the thick cables that is intended to be used for the motor and battery power supply ... the 5pin TC will be for attaching the 5wire cable coming from the SimAxe or the Arduino board ...
    cables will go in and out through the space between boards ...

    2014-01-18 06.07.24.jpg 2014-01-18 06.11.05.jpg 2014-01-18 06.16.20.jpg
    I used an old scanner lens to give me a good picture but I guess it has a small view angle:grin
    I'll try to get one of these sku_244994_1.jpg for my mobile phone .

    --------------------------------------------------------------------------------------------------------------------------------
    Yesterday I finished making the copper disk and I want to share how it's made ? ...
    first I found a supplier that can sell copper by kilograms ... I bought 15cm of a 6.5cm solid yellow copper rod ... that weighed 4.3Kg
    2014-01-08 15.09.07.jpg
    went to a lathe to cut the rod into 4mm slices ... gave me a total of 15 disks ... with a 3cm rod left over due to the lathe hub inside holding distance.
    total cost till no for 15 disks are 450LE /7 " Dollar exchange rate " /15 =4.28 USD for each disk ...:p

    used a sharp tool to mark where to cut and drill ... I can see the + marks scratches so you can too .:)
    2014-01-22 17.30.07.jpg 2014-01-22 18.11.03.jpg 2014-01-22 20.13.25.jpg 2014-01-22 20.16.20.jpg
    And gave it a good sanding and some polishing buff to a mirror shine ... I like that so I have to wipe out my fingerprints every time I touch it ... to be like I didn't do it :D

    And will continue soldering the MOSFET's as soon as I get some of the white stuff " heat compound " ...

    also found these types of cooling fans ... See how the aluminum core fan gets the biggest heat sink and is considered a bad cooling fan in computer world ...

    I guess when machining copper the brawn or reddish material it starts to accumulate and becomes like a sticky gum on the machining tool ... when machining Brass [ copper alloy with zinc ] the yellow material it is way much easier to machine and with the same performance of copper row material .

    tip : Bronze is a copper and tin alloy ... much harder

    I mill copper with coolant and a sharp carbide 4 fluted endmill. you need to fiddle with your feeds and speeds to get it cutting properly, it's a pain to mill.
