    Help required for Linear Power Supply build using LM317

    I did some research before making this circuit and people generally used higher value caps for power Lm317 based power supply. Most people use 10,000 micro F. Because with smaller caps, when the load is increased the ripples also increase. That is why I chose 4700micro F. I have seen people...

    Help required for Linear Power Supply build using LM317

    Sorry it's D2SBA60 . And I have connected the pot correct. It made the mistake when I was making the schematics.

    Help required for Linear Power Supply build using LM317

    Hi! I have been trying to build a liner power supply using LM317 voltage regulator but I am stuck.:mad::mad: Here's my schematic. All the values are also leveled on the schematic. Since, I was going to use this power supply to run a small DC fan I made so, I didn't bother to add extra caps...

    Disadvantage of several capacitors in parallel in a power supply?

    Hi! I am making a linear power supply. I don't have 10,000 μF cap but I have several 1000 μF caps. So, I thought I could add 10 of them in parallel to get 10, 000μF value. Will this cause any problem. This power supply is just for displaying in my class giving some basic demonstration like...

    How does an ATX power supply work?

    I was just trying to salvage usable parts. But now I have learned alot about SMPS and may be I'll be build one in coming future.

    How does an ATX power supply work?

    I was looking to build a bench power supply. So, I broke into an old ATX power supply to salvage parts. I found 3 power transistors [KSE13009L], and 3 schottky barrier rectifiers [S30D40C] but I didn't find any voltage regulators which I was hoping to find. I did find a packaged Bridge Rectifier...

    Replacement for a microcontroller

    Thanks...I looked at the data sheet...I would be really helpful..if you could help me implement it in my circuit!! I have never worked with this chip!! " The VCO requires one external capacitor C1 (between C1A and C1B) and one external resistor R1 (between R1 and GND) or two external resistors...

    Replacement for a microcontroller

    I had Lm386 laying around so i used it..the signal was really noisy but then i blasted that amp with caps..now its presentable..i will replace it!! i googled audio oscillator...and i found a video on youtube...will this circuit work?? will the signal maintain its form..this way??

    Replacement for a microcontroller

    hi! Thanks for the reply! I was thinking if I could send that signal though my microphone port on my pc...then write a app that would visualize it!! I mean..what my lm386 generates is just a signal right?? Similar to what my mic generates...if it is possible..it would fun :D ...i mean i could...

    Replacement for a microcontroller

    So...I am working on this ir heart rate monitor project...found it on the internet!! Its a really simple circuit...an ir emitter and a detector pair is used as a sensor...which is touched to your skin...it shines light up your skin and then reflected light is dected by the detector..this signal...
