Which wire is which? Answered

Ok, I have this solar panel I was given, and a knex motor without a battery box, and In need to test which wire is positive and which is negative on the solar panel. I am no good at electronics, though I have done soldering before. I was wondering, how do I test to see which is positive an which is negative on the panel? I hope to join it to the motor to have a very powerful, eco-friendly solar model.

Which is better?

Well i was just wondering which do you think is better ask.com or google.com i know google is more popular but which one is overall better? ask.com:pros: Can see screen shot of website. shows pictures of the search item on the side. shows blogs on side. gives you suggestions. I thinks thats it now for google. google.com:pros: Most browsers have a little bar at the top for searching. Most popular searching site. Can't think of anymore.. ask.com:cons: Not very popular All i can think of. google.com:cons:doesn't have all that stuff that ask.com has. That seams to wrap it up. What do you think is better? Also if you have any thing to add on the pros and cons list post them here.

Which Processor?

Hello everyone. I'm new here and I have a quick question about processors. I'm working on a project that requires a device to take inputs piezo buzzer elements and trigger an LED. The catch is I need a programmable chip so I can have pre-set outputs on the LEDs. I'd need something that can be rewritten (like an EEPROM) I've been thinking abuot using a PIC or a BASIC Stamp but I'd though I'd do a bit of research first.

Which computer is better? Answered

Hey, I'm trying to figure out which computer I should buy. One is an HP Pavilion HPE H8 with an Intel i7 third generation quad core at 3.4Ghz. The other has an AMD FX100 Hex core processor at 3.5Ghz. It sounds like the AMD is the winner, but I just want to be sure. I plan on running games such as Battlefield 3, Crysis 2, Saints Row 3, Medal of Honor, Need for Speed World, and about 7 or 8 other smaller games. The computer with the AMD processor has 8GB RAM and the i7 processor has 10GB, both have 1TB sata 7200rpm HDD. Which is faster? Which will run best?

Which Components to use? Answered

I want to make a circuit that is powered by 220v ac. It consists of a cooling fan that requires 12v, 0.7a, a  PCB with 10 LEDs in parallel that requires 0.25a, 3.5v and a single led that requires 3.5v,0.025a. I know how to calculate resistor values but it would be better if you give the values. I want to know which diodes should I use to make the rectifier and should I use a capacitor? In short, I want to know  how to set up this circuit, what components to use and their value and power ratings.

Which rotary tool?

I recently got some money from the government for my good grades (YAY!) So now I can get myself a nice rotary tool. BUT I can't seem to make a decision! I have 2 brands in my sights Dremel (No specific model/kit in mind yet) Gyros (http://www.amazon.com/gp/product/B006ZEJA56/ref=ox_sc_act_title_1?ie=UTF8&m;=AXL381AZQM9Q1) And if it isn't a POS Northern Industrial (http://www.amazon.com/gp/product/B000JFO1TM/ref=ox_sc_act_title_2?ie=UTF8&m;=AF8EGQ3KRZQB6) I am leaning more towards Gyros as their attachments seem pretty good. Its also significantly cheaper than Dremel. Please give honest feedback. Thanks!
