CPU grill?

I recently decided to make a mini-grill (similar to the gas/charcoal ones found around the site), but I want to be able to do it with electricity. My plan is to overheat a CPU with a heatsink attached and allow the actual heatsink to be the grill. The only trouble is that I can't figure out from the pinout which pins I have to supply power to. Could anyone give me an indication as to which pins they are? Also, any other advice would be appreciated. =) CPU Pinout: http://download.intel.com/design/Pentium4/datashts/29864312.pdf

CPU architecture idea/concept? Answered

I don't know much about CPUs or computers for that matter, but why hasn't anyone got the idea to take a multicore CPU architecture, and stagger the clock frequency of each core and have one shared cache memory between them all in the center so that the 4 cores can run one thread of machine code super fast? I'd imagine the reason we don't see clock frequencies greater than 4GHz is a problem with getting silicon to switch at those frequencies (maybe internal parasitic inductive and capacitive effects at the silicon level?) hence why multicore processors have become a thing? The problem I see with multicore CPUs is that programs need to be written in such a way so they can take advantage of parallel processing threads, and some tasks simply do not lend themselves well to parallel processing. Also, what is it about a CPU that determines the performance? It can't be just clock frequency(s) and the number of CPU cores, surely it has to do with some architecture and instruction-set stuff, but what exactly?

Custom uber simple OS?

After playing in the world of arduino for a while I have become curious if it is possible to use a common cpu, motherboard ect. To do the same thing as with a small microprocessor. Could one for example load the arduino bootloader to a cpu or just write to it with serial in order to use it for purposes similar to arduino and picaxe.  I know its a weird and wasteful idea but im just curious if it is even possible with modern electronics. I dont think it would be hard to find a junked old desktop and even if it was 1 mhz (much more likely to be 1 ghz) it would be extremely fast. Could you imagine an arduino with that clock speed! You could measure the length of pulses much smaller and you would be able to potentially handle 32 bit and maybe even 64 bit operations. Just a curious thought I had, could it be done and what would you do with such a system

How a CPU is born

    While doing some research, I saw a link that said "How CPUs Are Made: From Sand to Silicon". Mildly intrigued and not knowing anything about how they are made, I clicked and went to the page and read.     The article briefly runs through a highly abridged series of steps in the making of what eventually turns out to be an Intel i7 processor. It starts off with the raw materials (SiO2, e.g., sand) and how they turn it into monstrous (about 220 pounds!), essentially pure, silicon ingots from which wafers are made. and many steps later the processors are boxed up and ready for store shelves.

CPU Overheating? Answered

I have an Acer Aspire x1700 that I am trying to fix. I have replaced the 220w psu with a Seasonic 250w because this model is known to have bad power supplies (it wouldn't power on at all with the original psu). I also replaced the original thermal paste since I removed the heatsink/fan to clean it. When I got everything back in and plugged it in, no power. I read that the graphics card (Nvidia Geforce G100) can sometimes fail and cause the pc to not power on. I removed that and turned it on. This time it had power and booted normally to the Windows desktop. After about a minute the cpu fan became very loud, like a jet taking off, then it completly shut down. Could I have not applied the thermal paste properly and it was overheating?

How can I build a simple computer around a retro cpu like the Z80?

I am interested in building a small computer and had previously opted to build a very minimal computer out of discrete components (think 4- bit). Due to cost constraints and my skill level in electronics I don't think I can do this at the current time. So, I have opted to try building a small computer with a pre-built retro cpu. First, my two goals: <>I do not want a computer with extra capabilities like serial output or the ability to drive a display. I want a "bare bone" computer. This entails a dip switch input and led indicating output. I would also like the option to switch to some sort of latching system for the inputs and outputs so my computer can control and be controlled by peripherals as my skill level increases. <>Ideally I would like to have as few chips as possible. I was initially planning to use a Z80 as the cpu because wikipedia says it had the need for less supporting ic's than its predecessors. Also, there is a lot of documentation out there on the cpu. You may be asking why I am asking for advice then but the truth is because the Z80 computer building tutorials I have found all involve a screen and are more complex than I can manage. If there is another processor that is easier to work with, please tell me! As best I can figure, for my basic computer I would need: the processor, a ram chip, a rom chip, 8 latches for the input and for the output (for an 8 bit processor), an 8 switch dip switch, a clock, and an 8 led display. Are there any other chips I am missing (buffers or the like)? Also, how can a program be written to the cpu? My thoughts on this were that the very first address of the rom section would have instructions to read say bit 1 and bit 2 of the input. It would keep doing this if both were low. When bit 1 goes high it triggers the cpu to jump to a section of rom which performs a loop where it reads the input->stores it in a certain memory address allocated to storing programs-> increments this memory address by 1->reads and stores the next input. If it read a bit 2 initially it would jump to the memory address where program starts. All in all this seems like a very bad way to program, what is the best way to program? I am fairly certain that some startup program will need to be written to the first address of memory in the rom. Thanks for your help.

Printing scale for repurposed meter

I am doing a project to repurpose a Westinghouse KX-241 switchboard meter as a CPU process meter for my PC.  To to this I will have to make a new scale for the meter.  Here is the type of meter in question: http://www.allsbrookelectric.com/media/0e/a20792a12cc1c0e3dc7d2f_m.JPG The scale on the meter I have does not match the scale I need, which is 0 to 100 (percent).  This is a simple task: Just remove the scale from the meter, scan it, and modify the image as necessary with Corel Draw.  Then print the new scale on glossy paper and adhere it to the top of the meter scale.  Simple.  Except, if you notice in the picture, the scale of the meter is not all flat.  The outer edge of the scale where the lines are is angled outward.  If I try to apply a printed scale to this, the printed scale will have creases where the paper negotiates the angled portion.  Any ideas of how I can manage this without creases?

CPU: Multiplier vs. Bus Speed? Answered

Hi. I have been overclocking my new cpu (AMD Phenom II X2 550 BE) and I was all excited about having an unlocked multiplier, because of the Black Edition, yet I can't even stably change it! I was told that you should up the CPU bus speed as much as you can while leaving the CPU stable, then move on to the multiplier. Yet after I get to the stable bus speed (235) I can't up the multiplier even one notch. It is currently 15.5. This was the stock multiplier. My question is, is it worth it to lower the bus speed so I can stably increase the multiplier. And is there a way to stably increase the multiplier even after you max out the bus speed that I am obviously not doing? Thanks in advance.
