    Making 100 leds flash?

    Righto, think I have a good understanding of this now and guessing nothing much is changed in the whole circuit/schematics other than the mosfets, Think I may be able to do this soon as I buy the parts.

    Making 100 leds flash?

    I still don't fully know the terms but I was looking at this type of wiring for the leds (photo below) and I was wantting power 50x2 leds but dropped it to 40x2 leds

    Making 100 leds flash?

    for whole thing 2.4amp for each set of leds Im wantting to use 1.2 amp each led is 30mA. Is this going be a problem? and thanks for the tip about telling the type of channel

    Making 100 leds flash?

    If I could use that set up for the mosfets for this project. The Q1 would be a N channel mosfet? and Q2 would be the P channel mosfet you said in your last post? And these would be alright to use? N channel mosfet, http://www.digikey.com/product-search/en?vendor=0&keywords=fqpf13n06l P...

    Making 100 leds flash?

    Yes I was using another user name but I forgot the password for it and the password for the email used for it. Sorry I didn't point it out sooner I know them schematics were for the high power led. I was asking if I could use the transistors/mosfet I used to make that one to make this project...

    Making 100 leds flash?

    You should recognize it, you were the one that drew it up for me. Sorry about the late reply been in classes all week. Anyway I'm bit confused about what you said with adding another N channel mosfet in to the circuit. You talking about just adding another one in there hooked in with the one I...

    Making 100 leds flash?

    Seem the (Image 2.4) would cost the less to do, and using that calculator shown below that image 2.4 it said I could power 50 of them 12x4 with 47ohm resistors and 2 extra with 270ohm. Now I'm powering 100 leds it shouldn't mater because only one side of the set of 50 leds will be on. Then...

    Making 100 leds flash?

    Alright, thanks I'll re-read over the tutorial few times and look at them links for the calculations you were talking about steve. But there one problem I have thats going put hold on this whole thing, and thats my power supply. Its going be my car/cigarette lighter because I'm making this thing...

    Making 100 leds flash?

    Ok, So would this be right then with hooking them all up? (See photo below) and only thing have to do is find out the resistor need for the strings and add up the mA/Amps being pulled by them and see if the transistor will be enough to make it work?

    Making 100 leds flash?

    I really don't know anything other than the two transistors I've already have :p Also I took look at the "Got a question about driving LEDs? "and the part about (Image 2.4) "The fourth method is to put multiple strings in paralle" That would be the method I would be using to power all of these...

    Making 100 leds flash?

    Im trying to make two sets of 50 leds flash back and forth between each other using a 555 timer chip. I have made two leds flash back and forth between each other so far using these schematics shown at bottom of the page. Sorry its not like most schematics out there. I drew it up best I can so I...
