    rca - usb cables

    my computer has firewire, usb, ps2, vga, and parallel connections, but no svideo! im aware of the usb/svideo/rca connecters, but i'm looking for something for under $65. is there anything that will connect to any of these jacks that has rca av terminals for around $20 or $30? is there a circuit...

    car battery tap

    that's an idea. probably too much for me though. how small do you think such a cooling system can get?

    Airplane

    why the necessity for complete automation? i know radios can be expensive, but i'm thinking of building a small plane and using the conrols from one of those mini rc cars. they only cost $10 (even though the range is only 50') and they're great for experimentation, small size, indoor flying, and...

    car battery tap

    the module cannot be moved; the car would not run properly, if at all. i'm just looking for 5° here. i know there is alot of ambient heat i'll have to deal with, but if it doesn't work all i have to do is remove it. it's sort of a last option, ya know? what if i made an epoxy enclosure around...

    New in your chat, Basic Question: How to...??

    take the number off of your tranny and type it into any search engine. you'll find data sheet links easily that will answer most of your q's. there are also data sheet sites, but i don't know them off hand.

    ohm's law

    i want to limit the current for a dc circuit, but my book is confusing concerning ohm's law. it leads me to two different equations. it's a 12 volt, 4 amp device. anyway, it's volts/ohms = current right? 12 v/4 ohms = 3 amps ??????? please help clear...

    ionizer

    for this ladder will i need caps that will exceed the value of the final output voltage? what should the diodes be rated at?

    ionizer

    i'd like to make an ionizer so i don't have to spend $400 for one at sharper image. still, i'd like mine to be modeled on their version since it's apparently so good. (is it?) i'm thinking 10k epoxy transformer. i also heard stainless steel is best for attracting airborne objects. ideas?

    car battery tap

    im is ignition module in my 95 sable. it is tucked into the engine and mounted on the distributor where it gets very hot and when it overheats it causes the car to stall. ostensibly, it cannot be moved so i want to hook up a pj to the im. naturally, it would only operate when the car is on, but...

    car battery tap

    i'm going with the peltier junction under the hood for the im. i have a junction that apparently operates at 12v, 4 amps; is this a significant draw on a 650 cca car battery? what i need to know is how to hook it up. where do i connect the wires and should i use caps and resistors? thanks

    ignition module

    the ignition module in my car (according to some people) malfunctions due to very high engine heat (and module age). i don't know what's in the module (surely just some ic's), but when it does overheat the car stalls. the car starts when it cools off. if this is the case will an ic resume...

    solar booster for ac line

    i was thinking about placing an inverter (and some circuitry) on a solar cell and sending that ac juice directly into an electrical appliance (like a lamp). the cell would probably only produce about 30v at a couple amps. i got the idea that i could hook it up right to the appliance cord and it...
