vapor's method may work if the current is constant but usually isn't a very good solution. You can probably find a voltage regulator that will take in 5v and output 3.3v, searching at digikey found several that you would want. I'm sure radioshack would have something that will work as well

It would be possible to design one, and send it off to a pcb shop to get it fabricated. That would cost a little bit of money. If you wanted them to soldier everything on for you it would be even more. Just doing it yourself with wirewrap may be possible but it would be quite difficult to get...

buffers are used for two things in chips: 1. To create delay (usually used to fix hold time) 2. To increase drive strength of a signal. As mentioned earlier because the clock is distributed to 1000s of flops in the design the clock path is usually a tree to distribute a good clock signal to all...

Thanks for the responses. I have several specific needs. My input voltage is somewhere between 9 and 16 volts. I have two 470uF 16v panasonic F package VS capacitors on it in parallel. It then goes to a 5v linear voltage regulator I have 1(more capacitance in other areas) 1000uF 6V panasonic F...

Can someone explain to me about the values a capacitor has? I'm building a board and trying to decide what capacitors to use. I'm interested in how uF and ESR relate and what kind of things I should be looking for in a capacitor. I need capictors both for power supply filtering and to go off a...

As someone mentioned the best way is to keep your case positively pressured. To do this have higher inflow then outflow (more fans or higher speed fans) Then you just filter the inflow. The cheapest easiest way to do this is to take some old nylons and put them right before the fan. I did...

Here is their website: http://www.systemc.org/ I'm not sure if its free I haven't really investigated using it. I really hate system C as a language for synthesis but it is good for high level architectural modelings. I think some major companies do use it, most likely for architecture...

I've never had a problem synthesizing verilog to gatelevel or fpga level. As long as you write proper code you shouldn't have to do very much except size up a few gates to get it to run faster. Generally the private sector uses verilog and the government projects use VHDL. My first processor...

didn't mean to post this here.

I think glide looks better on ut then either d3d or opengl. UT was designed for glide first. I've never found a glide wrapper that looks good on UT though so good luck. Your best option is to get a voodoo2 sli and run 800 or 1024 also I play competitively so I have most of the pretty stuff...

you mean like something that takes a 12v cigarette lighter thing to your laptop? I think my laptop takes 18v in, so you theoretically just need a good step up circuit. The problem might be that laptops are fairly sensitve to input power (at least I think so, or they wouldn't have the expensive...

yeah the hc12 is pretty good, we just want something more around 100mips.

Yeah I would definitely go with pic chips for a cheap easy microcontroller. I just don't know where to buy any of the stuff, because the lab I work in already has it. You can also do in circuit programming, but it is slightly more complex, but makes it nice that you don't have to remove the...

I looked at the ZILOG and they seem to be a little slow, same with AMD =/ It looks like I might use the ARM, although I wanted to avoid it at all costs. I found a few other neat ones, TI has a nice DSP that might work, and ubicom is making the IP2022 which seems like it is also pretty good. As...

Do you have any other suggestions on processors? Both the rabbit and arm seem like you have to do a lot of off chip development like adding in RAM and ROM. Pics/STAMPs are definitely way too slow. Unfortuneately power is a huge issue, so getting a single board computer probably isn't ideal...
