Amazing Rubber Band Cars

Filed under: Uncategorized — admin @ 1:41 am

Kathy’s college roommate’s, Annelle’s, husband, Mike, has published a book: Amazing Rubber Band Cars.

During the past week I’ve been building one of the cars – a big one. More information to follow when time permits.

I sorted, and inventoried the 6085 Black Monarch’s Castle.

Thanks to peeron.com for the inventory list. I am missing a number of parts for this kit. So I have ordered a few of them to try out the Brick Link site and one of the vendor there named Pooh’s Corner.

Bought a Lego Mindstorm NXT

Today finally I won the bid on a Lego Mindstorm NXT robotic system on eBay.

I’ve been trying to get one for the past few weeks, but have been over bid time and again.

I week or so ago I bought a MiniPOV3 from Make magazine, Makezine. Yesterday I purchased a Weller WLC100 soldering iron, a Panavise Jr Model 201, a Z-TECH Helping Hands with Magnifier Model 53-003, some 60/40 rosin core solder and 5 ft. of .075 inch solder wick from Frys electronics.

MiniPOV3 circuit board in vise.
Today after doing some yard work, I put together my MiniPOV3 using the MiniPOV Instructables. I switched it on and it worked the first time. Neat. Next I downloaded the WinAVR development system. I attached the MinPOV3 to the serial port of my computer and reprogrammed it to say “I Love Kathy!”. Neat again. My plan is to learn more about the ATtiny2313V-10PU.

Weekend busys

Filed under: Uncategorized — admin @ 2:56 pm

Well I’m trying to keep myself busier on weekends.

I did my 7 mile morning run with my running class. I ran with a good crowd including Chris, Jay, Robert, Celeste, and Glenn. We chatted all the way which was nice. This class and my running continues until next February’s Austin Marathon. Wish me luck. I need it.

After arriving home I cleaned-up and then I added 1GB of RDRAM to my son Matthew’s old Dell Dimension 8100. I had purchased this memory on e-Bay last week. The memory was not cheap, but the machine is a 1.3 GHz Pentium 4 which is better than my old 800 MHz AMD Athlon that I had disk nuked a week or so ago. Next I installed Linux Fedora 7 on it, and I installed some work things (Cell Broadband Engine Software Development Kit) on it too. Now it’s ready to go and with the additional memory the machine is quite snappy so it was a worthwhile purchase.

I again continued to reduce Lego entropy. Earlier this week I sorted, and inventoried the 8854 Power Crane.

Thanks to peeron.com for the inventory list. I printed out a copy of the inventory and cut it up it into strips contains a related group of parts. For each group I put the cut up strip into a snack-size baggie, found and counted the parts into the baggie, and put the now filled and sealed baggie into a larger gallon-size baggie. For this kit I am missing only three parts. Now the question is: where can I get them?

Then I sorted the hundreds of miscellaneous parts (non-blocks or plates) into groups and put them into baggies. I really need several containers with little divided sections.

This might look messy and totally disorganized, but actually it isnt’t. Each bunch is a group of the same type of piece regardless of their color

Update: My friend Larry P. told me that you can get Lego blocks from bricklink.com. The site says “BrickLink.com is a premium venue for individuals and businesses from all around the world to buy and sell new, used and vintage LEGO® through fixed price and auction services.”

Reducing Lego Entropy

Filed under: Uncategorized — admin @ 2:35 am

I decided to sort three banker boxes of Lego blocks this weekend. These blocks were given to our children and had collected over the years. When they left home we bundled them up, and put them in the garage. Overall I consider this job a way to reduce the randomness of the “system”, that is, to reduce the entropy of the hundreds of mixed pieces into a more organized system. Based upon thermodynamics it always takes more energy to accomplish. Well it has been hours and I’m still doing it. So it sure has taken a lot of my energy and I’m still not done.

First I started on the miscellaneous bags of blocks. I sorted them into brick, plates, and special pieces. Then I sorted the bricks and plates into specific sizes, for example, 1×2, 1×3, 1×4, 1×6, 1×8, 1×10, 1×12, 2×2, 2×3, 2×4, and so on. I then packaged each group into their own ZipLoc bag ranging from massive gallon ones (for the 2×2, 2×3, and 2×4 bricks) to sandwich ones (for the 1×3, 1×4, and 1×6 bricks) to small snack ones (for the rest). I have yet to sort the special pieces further so they are just in five large ZipLoc bags for now.

We have four kits that were special and I like to keep them separate. There are now websites, for example, peeron.com and brickset.com that provide both the inventory and instructions of many of the Lego kits. The first kit I worked on saving is the 8865 Auto Chassis, the second will be the 8854 Power Crane, the third is a yet to be identified castle, and the fourth is another yet to be identified train. I printed out the inventory and began to sort the pieces. I slowly got the Auto Chassis under control. I cut up the inventory sheets and put the Lego pieces with their inventory slip into numerous ZipLoc bags. I also printed out the 38-page scanned instruction manual, punched holes in it and put it in a folder.
I’m going to leave the Power Crane, castle and train for another weekend. I’m pretty sure I have most of the Power Crane, but I am not so sure about the castle and train, because they were already broken apart and spread into many miscellaneous bags.
Update: Castle is 6085 Black Monarch’s Castle
Update: Train is 7720 Battery Train Set

Disk Nuking

Filed under: Uncategorized — admin @ 9:14 pm

Over the past few years I’ve been collecting old computers. Some have been mine and others have been my children’s. They have now gotten to a critical mass of four and I think it’s time to get rid of some of them.

Left to right: my cream-colored Gateway 300Mhz, Justin’s silver homebuilt from his college days, Matthew’s black Dell Dimension 8100 from his college days, my cream-colored homebuilt 800Mhz AMD Athlon
I’ve selected one (Matthew’s old desktop machine) to be my next Linux system (previously I was using my Athlon machine). However, Matthew’s machine only has 128MB of memory and is seriously strapped performance-wise because of it – for example, no X-windows. Yet it’s the best of the bunch since it has a 1.3GHz Pentium 4. The downside is that it requires PC800 RDRAM memory which is expensive. While doing other things I’ve been sitting on eBay today bidding on 1GB (2x512MB sticks) of memory for it.

Now I have to get rid of the the other three junk machines. So today I’m also sitting here running Darik’s Boot and Nuke program from a CD on the Athlon machine. Running this program is not just a simple minute or two process. So far a 40GB drive took about 3 hours whereas two 20GB drives took about an hour each. Right now I have started a 20GB drive, and have a 30 GB and a 6GB still to do. You have got to have patience doing this.

Lazy Labor Day Weekend

Filed under: Uncategorized — admin @ 8:45 pm

We spent the last two days in Wimberley, Texas at the Creekhaven Bed and Breakfast. We ate, watched DVDs in bed, shopped, slept in, and ate some more. Breakfast was a buffet each morning, and Sunday’s french toast was especially great (done as a casserole). Also this was the first Saturday of the month, so that meant it was Market Days in Wimberley. We spent a few hours there touring the hundreds of booths, but we were good and didn’t buy much “stuff”. Kathy got some small stitched pieces, and I bought a DVD. It was so nice to just spend a few days together, just us.
