    Just a quick check of my circuit

    Im not helping with your circuit, but just a comment about keyboards today - why do the keys always lock each other from turning on, seems like such a dodgy design, that everyone takes as the norm today. how crud are the keyboards we use!?!??

    New idea for oscillator

    I think you guys actually understood what i said to some degree due to what you replied, so ill keep my boasting to myself, whats the use of giving good ideas away. :)

    New idea for oscillator

    In your definition what is it?

    Accuracy Component Tester.

    1% error sounds really great until your talking about pico amps, then its 0.00001% accuracy required i think.

    New idea for oscillator

    Ive just got this crazy idea, where I was thinking an oscillator pretty much is a capacitor, in a loop with another capacitor (with a controlled voltage of course.), and back and forth it goes pinging off its transistors. I was wondering, it seems like it would be a lot of work, but if u...

    Small solar power constant charge to charge a big capacitor.

    You discharge it on a second loop with your "on switch relay", in the loop its in with the solar panel its in its non discharging state - it should just fill up- and wont give any electrons off until the second loop is actually closed, then it will neutralize. I think its another feature of...

    Small solar power constant charge to charge a big capacitor.

    Thanks for replies. wouldnt charging with a capacitor be better than a battery, because there is no reverse to the charging current in the system?

    Small solar power constant charge to charge a big capacitor.

    Is there any way to do this, say to charge the capacitor even on cloudy days, As far as I can think, the small charge will reach voltage equalization with the capacitor and itll just block too early. But I bet there is an easy way to do this, because its such a common thing going on...

    simple resistance calculation exercise

    Another way to do it, thats kinda still a bitch to do... Is to just draw each loop from the battery separately, and then complete the resistance calc of each loop, then add them up to get your amps - for all locations on the circuit. (where the loops overlap, you have to count all loops go...

    Is a motor also a dynamo?

    I should experiment more then, getting more efficiency is probably possible since im only sitting at a dribbly ~ 6% output watts to input watts with what ive got now. plenty of room for improvement.

    Fruity loops track

    Clipping it off at different ranges I get different vocal characteristics.

    Is a motor also a dynamo?

    yep, its working. thanks that last tip was the one.

    Is a motor also a dynamo?

    holy **** your right!!! haha, ill try again!

    Is a motor also a dynamo?

    Its probably useless saying it, but they were smoking out of my VPS. I guess ud get more if you could spin more than one, but one did not work at all.

    Is a motor also a dynamo?

    Yes shucks. :)

    Is a motor also a dynamo?

    Yes, i might go get myself a multimetre - but it should be enough to light the leds, especially if i hammer the back of the motor with watts right? I got no response at all, gets me superstitious. Just one last question - the output is dc from a dc motor, because of the commutator right?

    Is a motor also a dynamo?

    yeh sorry, meant leds. yes they are parallel, opposite polarities. (im actually quite experienced, ive done many experiments by now. but it all still confuses me.) red and yellow. red one could be damaged, but it still works with a 9v battery, theres about half the life of the battery left...

    Is a motor also a dynamo?

    geeze, no need to be so rude! what the hell is a sand groper? 1) they have a magnetics to them, they constantly stick to things. 2) not sure, they are small hobby motors. i had the power supply flat tack for a little bit. 3) havent got a multimetre. 4) i had back to back diodes - so current...

    Is a motor also a dynamo?

    I tried soldering (ed: the shafts) two motors together and connecting an led to one of them, and powering the other, but I didnt get the led to light up. I read this thing on faradays law which said you can rotate inside a magnetic field to get a current, but it didnt work two motors...
