Anyone working on SBC & BSD solution?

12-15-2001

I'm looking at building a Single Board Computer with some form of BSD or other *nix version that will support WEP cracking utils.

My goal is to make something small that I can dig a shallow hole and stick the computer in. I'll use an omni antenna to obtain the signal.

I'd obviously need a HD interface for the amount of data that I'd have to collect to crack WEP.

I'm thinking that once a specific amount of data is collected, say 2 gigs, it can emit a particual signal that I'd be listening for to alert me that it has collected enough data. Or maybe even it would crack as it collects so the minimal amount of time is used.

Well, that is a goal. Anyone else working on something similar?

that may be partially adapted to what you're trying to do.

That's the link. At the very least, it's a starting spot. Give it a shot. Perhaps someone else would be willing to design a wireless bridge for it (no easy task).

I'm looking at Celeron CPUs with USB, VGA/LCD, Serial, LAN, PCMCIA, IDE, and CF. I can't seem to find the PCMCIA and CF together.

But, here are a few sites that a google search for SBC turns up.

got the impression you were looking to roll your own from scratch.

Tron- any specific reason you are looking at an sbc computer versus a cheap used laptop instead? I have built 2 pc's based on sbc's, (because a good friend got two picmig sbc's for me free)and although they work great, the cost of these things is outrageous if you buy these boards new. The boards I have list for $500 each! I kicked around the idea of building a sbc computer for the truck for mp3's. After considering the cost of an lcd display and other hardware, I settled on a used pentium laptop with a new 20 gig hd instead. And you said you were going to bury it???????

How about an I-Opener? They're pretty easy to find, have most of what you want, and have hack links all over the 'net on how to add the rest. Best of all, if you ask nice, a lot of people will give them to you; when the company died the units instantly turned into large paperweights.

Let's see, add a HD and a USB 802.11b unit, throw it into a Pelican box [check local dive shops, you have plenty of those in FL :-) ], add an external antenna. Voila! You're ready to go dig that hole.

Hey, Now that I think about it, I believe I'll build one!

LOL Seriously. I want a compact unit about the size of 2 3.5" floppy drives. This would include the hard drive, NIC, battery, etc.

A laptop is just too big for my desires and I don't want a screen and keyboard stuck on the unit while it is out "in the field". Also, with a used laptop, I'd probably have to replace it's battery too which are way over priced.

I've considered using a SBC for several of my projects (MP3 player, etc), but cannot justify paying the (unreasonably high) prices charged for these boards.

Here's an alternative to a laptop-

A very small, cheap 'subnotebook'.

Tron- I understand you want the smallest possible package for the sbc. But my point is - what are you going to use to power this thing? If your plan is to leave it buried for days at a time, the size of the batteries needed will be far larger than any notebook pc. The size difference of batteries and sbc versus batteries and notebook will be insignificant. What type of battery / power supply do you plan to use? Please do not be offended, I am not trying to be a smart ass. I am just curious as to how you will assemble this thing. Thanks

How about a car battery, adapter and a laptop. I thought about just taking a whole car with a laptop in the trunk and a disconnected 12v battery to run it and just leaving it set someplace.....'course, that was when I though WEP could be cracked in a an afternoon of normal network traffic. Now that I hear you need a week of listening to audio 24x7, that makes it a little more difficult....that car sitting by a nearby road would probably have bottles through it's windows by then.

12-17-2001

Valid point with the battery and all question. However, a laptop will just require a much larger battery then a SBC regardless of how long I let it run.

As for the batteries I would use, I would use the Gel Cells that are used for alarm systems. I have 3 or 5 - 7Ah units that are about 4"x1.25"x2.5" that I use to use on my 486 laptop and other goodies.

My goal for size is 3.5"x5"x?" or there abouts. Weight is not a factor. To cut down on power requirements, the speed of the CPU isn't even important so a 386 or 486 would work. After all, I'm just capturing packets and writing them to disk.

Cool- post again if you get something assembled and running.

Tron,
You might want to check Circuit Cellar: www.circuitcellar.com and www.micromint.com. Back when CC was in the old Byte mag, Steve Ciarcia (sp?) used to have a lot of SBC projects. Seems to me that just after they became Circuit Cellar Ink (c. 1985), they had a "Data Logger" designed for remote location monitoring. An updated version might be ideal.

As far as battery power goes, the biggest load will be the HD motor. If you wrote to some sort of non-voliatle RAM disk, your power requirments drop pretty quickly. I think CCI had a lot of those type of circuits, too.

The problem with using NVRAM is that to capture enough WEP data is impossible. Cost/Capacity issue.

Not sure if this is exactly what your looking for, but you've got to admit they look very nice indeed :-)
