    LM317K regulator current problem

    I fond the answer, The vcc+ would come off the output of the lm317. But according to the data sheet of the LM301 the max input voltage is 22volts so how can it work if the LM317 is produceing 30 volts?                                     Thank You                                       gogo

    LM317K regulator current problem

    Hello   I have been looking at this circuit for awhile and the only thing I don't under stand about the LM301 is Pin 7 VCC which would be what. The output power of the LM317 or the input power.                                 Thanks                                 gogo

    Transistor BF 494

    Hello Staigen     Your right about the BF494< I checked mouser and they have it for 20 cents.         I check the data sheets on th 2SB1382 wow what a difference between it and the 2SK1382. The transistor Has SK under lined on top of the part number, So I am guessing that it was made by...

    Transistor BF 494

    Thanks audioguru             I will give a try. Right now I am in hot persuit of info on a power transister  SK  B1382. Just because I have one and I want to see what it can do. I hope that makes sense.                                     Thanks gogo

    I need help with a prototype design

    Hello     555 ic's have been around for a long time the 555 ic only cost about 30 to 50 cents , depends on were you buy it. Cheep but it dosen't have brains. A mcu dose, I don't think you want to go with that, Willian is right about using a Pic mcu for what you wnat a 14 pin pic could very...

    Hi Five for Radio Shack

    Hello         I'm am new to electronics, I read a lot off the web and have a little understanding. Lately I have been disasmebleing old printers for the stepper moters and stuff. Now I have a solder sucker one of those spring loaded ones, it works. But today I went to the big town were there is...

    Transistor BF 494

    Hello Mettula   I am new to electronics too and understanding the difference in transistors is a project all in its own. I found the data sheet for the BF494 and will post it. And try to come up with something for. Boy wish I could find data sheets for my collection or transistors.              ...

    High current H-Bridge

    Hello Kosoniscs   35amps wow, your talking 10 or 8 gage wire. A pcb couldln't handle that kind of current so you would have to build it in modules using isolators. I'm thinking three modules. One for the low curent comos controllers, second for chopping the curent, and third for relays to...

    Stepper motor controll

    Thanks for the replies.     I have been pulling out mostly unipolar steppers from 5volts to 30 volts. Some 1.5deg, 7.5deg steps.   The power supply I have my eye on is multivoltage +5, +12, and +40. Not sure how to use it yet but its nice, pulled out the 2amp transformer had a power switch ...

    Stepper motor controll

    I have a project in mind.     I would like to make a tester for stepper motors that I could but on my bench, Something that looks pro. The mcu would be a Pic 16f628a or 48a.     Need to have to Voltage output. One +5 volt for the Pic and Logic. Other 12 - 30 Volt for Motors ( would like...
