    A question about electrical Theory

    The one i saw had a digital screen. Buttons were used to adjust voltage. I suppose i could google a schematic. But i enjoy the discussion. I find it more informational sometimes to discuss things on here rather than read data sheets and schematics and just thinking by myself

    A question about electrical Theory

    Yes i see where youre going with this. I suppose a potentiometer of some kind could be involved. If there was one in the module itself this makes perfect sense. I understand about the lightbulb too. This is probably how they achieve different resistance in different coils.

    Fidget Spinner Generator :)

    Haha this is pretty cool. How much power can you generate?

    A question about electrical Theory

    I suppose the module itself could be pulling more current from the batteries.

    This is true... I was forgetting about resistance. V=I^2×r if im not mistaken?

    A question about electrical Theory

    No the ohms are an advertised value. Unlikely to change much.

    A question about electrical Theory

    Yeah I thought it didnt sound right. You can see by my last reply why I had the thought in the first place. Like i said i realise this isnt a real life scenario. Lets say on paper... 100 watt light, 10v , that gives us 10 amps. Take the same system and put in a 150 watt light. Would amperage or...

    A question about electrical Theory

    Take a va What sparked the thought is my co workers vape. It is adjusted in watts. So what i gather is when you increase power you are pulling more current. The voltage shouldnt vary much since the power source is a battery.

    A question about electrical Theory

    Im just curious here. This isnt anything im working on. I was sitting back thinking and it occured to me... I know Power=Voltage X Amperage and when either voltage or current is increased, so is the power. Now this may not be a real life scenario but if the power in a circuit is increase (not...

    That may be a little out of my reach haha. Very cool idea though

    Salvaged components

    I just salvaged a printer. What did you build with the motors and gears?

    Pickit 3 vs Arduino uno

    I can appreciate that. I agree with the baby steps. Sometimes i have to go back to basics just to do something im good at haha. But i find it hard to give up on things. Even after a month ill think of something in the middle of the night and have to go try it.

    Pickit 3 vs Arduino uno

    Good stuff to think about...I built a computer awhile ago and loaded it with Ubuntu. I have been considering loading windows 7 as a boot option. I guess this is a good reason to do it.

    Pickit 3 vs Arduino uno

    This was kind of the question. Start with a plug and play type of system? Or start with raw materials and learn all the ins and outs.?

    Pickit 3 vs Arduino uno

    Most definitely. But this is what i do. I find a challenge and i learn.

    Ill be using Linux. I heard Linux is very useful for programming.

    Pickit 3 vs Arduino uno

    160 usd is a little steep. I may have bought a chinese copy. I don't have any experience with embedded programming or using uC so i guess i will find out if its junk when it gets here. My comment was merely poking fun at a truth in the world today.
