Making, baking, and (un-)breaking things in Southeast Michigan.

Maybe it’s the caffeine…

I just had an interesting idea:

You all know that random number generators are not truely random, as they generally get their input from something that could theoretically be predicted (temperature, radio background noise, etc).

I think it would be interesting to see if a person could be used as a random number generator. The data could be fairly easily gathered by sitting a person down at a speech recognition device that will respond to ‘one’ and ‘zero’ or ‘yes’ and ‘no’, recording them as bits in a key. If the person were to rattle off 1024 yes/no or one/zero answers, then you would have a 1k key. My presumption is that if you told a person to randomly pick one of the possible answers, they would tend to get fairly random after a while. But, it would be interesting to see. Standard tools for analyzing randomness of data could be used to see just how truely random the person is. It wouldn’t be hard to collect a number of high-bit samples from an individual, nor would it be difficult to collect samples from any number of people, allowing for proper analysis of a human-based random number generator. It’d also be an especially geeky way to generate PGP/GPG keys.

Also, WeatherBug says that it is 0°F outside right now. I’d confirm this, as about an hour ago I was buying gas somewhere in the 9 Mile and Woodward area and I was just standing there, shaking, being amazed at the stillness of Ferndale and how crisp and dry everything seemed. At those temperatures snow is almost like gravel. It’s no longer slippery, it’s almost like the dirt on a freshly plowed country road, crunchy, blowing in bizarre egg-dipping-oil-like patterns across the highway.

Ah hah!

Ahh… So I finally found information on the weird fenced in hazardous waste area that borders Riverbends Park and Waldon Lakes (or Waldon Ponds or whatnot) Park in Shelby Township: http://www.epa.gov/R5Super/npl/michigan/MID067340711.htm

There were oil lagoons!!!

UPDATE: Scratch that. This is the place I’m thinking of: http://www.epa.gov/R5Super/npl/michigan/MID980410823.htm. Note the water treatment plant… That’s right in the back of the Waldon Lakes park. Unfortunately the park is all fenced in, so I can’t get to the rest of the recreation area.

Hurray!

Yay! I *FINALLY* have a functioning laser printer at home. See, in 1995 my parents got me a LaserJet 5L for Christmas. The thing always worked fine. It prints great, everything, but after a while it developed the typical LaserJet 5L/6L feed problem, much like they all did. It turns out that there is a place called fixyourownprinter.com which sells kits and instructions for fixing common printer problems. So, $30 and about half an hour’s worth of work later, my printer works fine. Woo! I also threw in a spare toner cartridge I’d had since 1996/1997 and physically cleaned the printer up a bit, and now it’s like new.

HDD for PS2

Okay, so I did it. I put a hard drive in my PS2. And guess what? Nothing happened. The disk spun up and there would be occasional activity on the IDE bus, but nothing beyond that. I was hoping there’d at least be a new menu option or something that showed up. Oh well…

Just FYI in case anyone feels like playing with it, a Quantum 840MB disk fit in there perfectly. I would have tried something bigger, but that is all I had to play with. See the previous post for information on the Maxtor disk.

PS2 HDD

Hrm… So I got a Playstation 2 network adapter. The curious thing is, it seems that there are connectors for an IDE hard drive as part of the adapter. It doesn’t fit a Western Digital hard drive that I have, but maybe another? Possibly Quantum… They seem to make a lot of disks for OEM applications like Tivos, etc.

UPDATE: This picture make it look like a Maxtor disk along with a bit of hardware to mount the drive more securely. I just need to see if I have a Maxtor disk around anywhere…

UPDATE PART DEUX: Okay, I should do a little more digging next time. The PS2 Linux dmesg output from this page indicates the following:

PlayStation 2 IDE DMA driver
hda: Maxtor 4D040H2, ATA DISK drive
ide0 at 0xb4000040-0xb4000047,0xb400005c on irq 41
hda: Maxtor 4D040H2, 38146MB w/2048kB Cache, CHS=4863/255/63, (U)DMA

So… Yeah. It is a Maxtor. And since the PS2 Linux kit ships with the same network adapter, all I need to do is find one of these drives. Or any old Maxtor. I wonder what the machine will look like then… Or how the disk needs to be formatted for games to support it… It’d be nice to have the QCast Tuner also support playing from a local disk. It’d be nice to be able to play off of both the network and the local disk. Or imagine if there was support to rip audio right into the local disk… Mmm… I wonder how fast the PS2 would actually be at doing audio compression?

Nixie Tube Clock

Well, I just pretty much let the auction evaporate at $125 for the clock. I think what I’m going to end up doing is building this clock right here. There’s a couple of reasons for this… A) I’d really like to actually build my own clock, I just hope I do a good job soldering and such. I’ll probably have to practice beforehand on some old motherboards or kits or something. B) I’d like a clock where you can see at least some of the circuitry. C) This clock listed here is built to sync off of the WWVB transmissions, much like a few of the other clocks in my house. This is a GREAT feature. D) This clock uses huge Z5680M 100mm high tubes (50mm numbers) which will be nice from reading across the bedroom. I’d also be able to finish the base in a color which would better match my bedroom, where the clock will live.

So… Yeah. No clock for me tonight. It’s probably better for my pocketbook, anyway. Oh, I just checked and the auction jumped to $154.25 at the last minute. So, it’s good that I didn’t bid. Oh well, I’ll build one eventually. Maybe after this current computer job that I’m working on for my dentist. That job is paying about $500 and is for upgrading three computers. That extra $500 should pay off my CC. Maybe with whatever is left over I’ll get the necessary stuff for the nixie clock. While I want to work on the bed, I need to wait for it to get a little warmer out. This would be a good winter project.

Nixie

So I want a Nixie tube clock… Here’s the problem. There are some really nice clocks up on eBay, likely to go for the same price as it would cost me to build a clock. The question is, how soon would I be able to build a clock? I’d love the warmth of a nixie clock in my bedroom, but should I wait and build one and hope I do it right, or spend the same amount for a nice looking, finished, functional clock?

Local News Sucks

Gee. WDIV / Channel 4 just had an aweful story about war driving. What a load of garbage. Hey, guess what? You just learned more about war driving from this post. Yep, that’s how detailed it was. I’ve captured it and I’ll upload it somewhere later. I screwed up and made PCM audio, so I have to rip that out, redo it as MP3 and readd it. Aww, screw it. I’ll just up it now. It’ll be at http://www.nuxx.net/files/wardrive.zip once it’s done uploading. Feel free to take it. It’s ~58MB, though.
