I Love Michigan’s Scanner Law

I love what is known as Michigan’s Scanner Law. In short, this law states that if one is charged more than the stickered price for an item rung up via a computer scanning a bar code, one is legally eligable to be refunded the overcharged amount plus ten times the overcharged amount, with a cap of $5 on this surplus. In this case I went in to Office Max to check the price on a Logitech LX8 mouse. It was marked as $29.99, so I purchased it. As expected, it rang up for the normal price of $39.99 and the cashier didn’t notice the stickered price.

After a quick walk out of the store then back in I returned to the cashier and asked her about the difference, which she promptly refunded. I had to remind her about the aforementioned Michigan Scanner Law, but doing so resulted in a manager being called over and my receiving an extra $5 cash. Thus, what’s normally a $39.99 MSRP mouse ($49.99 at Office Depot) was obtained for $26.79.

The last time I took advantage of this I obtained a large quantity of 2GB SD (20 or so) cards from Micro Center, most of which were marked $5.99. I was charged $6.99 per card, and upon visiting the customer service desk I was refunded $1/card. When I reminded the cashier of the scanner law she simply re-rang all the cards at $1.99/ea, essentially a $5 penalty per item. When multiple items have their price adjusted the store must correct the price on all and refund the difference, but they are only obligated to pay the 10x penalty once, but if Micro Center wanted to do otherwise, I was not going to go out of my way to correct them.

My NiteRider TriNewt Is Broken

Tonight was a perfect night for a ride. Beautiful clear skies, upper 50s, and a light breeze greeted us as we rode from my house to River Bends Park to poke around the new limestone path and some unofficial single track. Not long after entering the park we even ran into some other people we knew who were out enjoying the same trails.

Heading back into the woods things were going well, until I ducked some overgrown brush and caught my head light. While I stayed on the bike, my NiteRider TriNewt stayed with the brush for a bit, breaking off the mount and apparently stretching the cable to uselessness. I was then left holding a non-working head light, roughly two miles into overgrown single track trails which were frequently bench cut along ponds. Thankfully the two people I was with rode behind me, so I was able to see well enough to make it out, even if some of those points involved ensuring that the front wheel was pointed at the narrow, dark shadow in front of me.

Once we made it back to the wider limestone / paved paths in River Bends things were much easier, and I was generally able to ride along next to people, using overflow light to see by. We were then able to finish up a nice loop, totaling ~17 miles. I’m quite lucky that I wasn’t out alone tonight, as a broken light six miles from home on trails would have meant lots of walking and not-safe riding.

Tomorrow I’ll try contacting NiteRider about getting the light fixed. Per their warranty website this should cost $30 in bench time, plus a new cable and light mount. I opened up the light briefly to check for broken solder points, but everything looked fine, so I suspect the cable. Since the cable and its strain relief is not something I can easily remold myself, I think I’ll just pay them to do it. Hopefully I can have it back quickly. Until then I will probably be using a borrowed HID, which should be interesting. There’s a reason why people are moving in droves to LEDs for bike headlights.

CO2!

Danielle brought me a box 1/3 full of dry ice today, as it was left over from a shipment they received at the lab. Thus far I’ve placed it in water, put it in soapy water to make a bubble tower, drowned it in apple juice (and drank the juice), and lowered burning magnesium into a sink full of CO2. The magnesium sputters a bit before going out, and the juice tasted nicely acidic with a bit of carbonation. Now to figure out what else to do with it.

It’s being stored in a foam box, in a cardboard box, on the front porch. I imagine there will be plenty left to play with tomorrow after work. Now to think of things to do. Ice cream is an option, although I’m not sure of that one yet…

Tarkan Akdam’s iFlash iPod Compact Flash Adapter (mk II)

I use my iPod daily, both in the car and at work for listening to music. I’d also recently come across a nice little PCB made by Tarkan Akdam called the iFlash iPod Compact Flash Adapter (mk II) which allows one to replace the 1.8″ hard drive in their iPod with a CompactFlash card. This card is a very nice, basic design, and can be purchased for a very reasonable price directly from the person who came up with it.

Since the hard drive in my iPod will eventually fail, I wanted to replace with flash before this happened and sell the working disk on eBay. A few months back I’d purchased one of Tarkan’s adapters for Ā£14.50 (US$24.45, at the time) and kept it sitting on the shelf, waiting for a good time to do the replacement. Seeing that a 32GB Kingston CompactFlash card could be purchased for roughly $76.25 from Newegg I figured that now was the time, cashed in some change at a Coinstar machine, and ordered the card. (I was originally going to purchase it with an fee-less Amazon gift card from Coinstar, but the machine couldn’t issue one and thus did fee-less change counting. I then made the purchase from Newegg, who had faster free shipping.)

I’d also considered replacing the battery at the same time, but as I still get great battery life out of my iPod, I couldn’t see the need. Opening the iPod is easy enough, so when the time comes to replace that, I’ll do so.

The 32GB CF card arrived yesterday, and since I’m home watching Danielle as she recovers from having her wisdom teeth removed, I set to work today installing it. Opening the iPod was easily accomplished using one of Danielle’s guitar picks, and after disconnecting the flexible PCB cables and removing two little gray plastic spacers, the compact flash adapter was placed in the iPod frame, where the foam rubber cusions made for a nicely snug fit. After closing the iPod it presented me with a screen indicating that it needed to be connected to a computer for restoration, which puts the OS back on it. After doing so, the flash conversion was complete.

Since there is no longer a need to wait for the disk to spin up, the UI is much more responsive now. Battery life should also be improved greatly, as flash takes less power to run. The only current downside is that the iPod now feels off balance. Previously it’d felt very evenly weighted; solid and firm, but not overly heavy. Now the top of the device, where the battery is, feels a bit heavier than the bottom. Thankfully this shouldn’t matter for me, as most of the time my iPod is sitting on a desk or in a car mount.

Later tonight I’ll post an eBay auction for the old hard drive from the iPod, a Toshiba MK3008GAL 1.8″ 30GB hard disk. I hope that it’ll fetch $20 or $30, to offset the cost of the flash adapter and card. Now, here’s to hoping this iPod has another three years of life left in the rest of it.

ATI Radeon 4870 Flashed For Mac Pro (MacPro1,1)

I’d occasionally been considering picking up a new video card for my Mac Pro (MacPro1,1) to replace my NVIDIA GeForce 7300 GT, but the new ones are very expensive. Typically there are ways to flash PC video cards with Mac-compatible (OF or EFI) firmware, but reliable methods and card versions aren’t always the easiest to find. However, last week I was looking into it and all the pieces came into place, with good flashing instructions and firmware available and a relatively cheap, compatible card appearing on eBay.

First, I ordered two power cables from ATI, Power Cable for RadeonĀ® X1900 MAC G5 Edition. These cables allow one to get PCIe 6-pin power connectors from the Mac Pro mainboard. Most modern video cards require more power than the slot can provide, so these connectors are generally connected directly to a PC’s power supply to provide the extra needs. As Macs tend not to have extra connectors just hanging around in the case, Apple provided the power connectors right on the main board. These cables thus plug right into the main board (Picture) up near the SATA connectors, then connect right to the back of the video card (Picture).

Next I purchased a Sapphire 512MB ATI Radeon HD 4870 from eBay with a winning bid of $110 (Auction Mirror). This shipped quite quickly, and arrived in great shape with all the original retail box items, which was a pleasant surprise.

After getting the card and the cables, it was time to install it and flash it. To do this I followed Alexandre Boeglin’s article entitled How to flash a PC 4870 for a Mac Pro, using only Mac OS X. I’ll recap the steps that I performed here:

· Acquire the iMac Graphics FW Update 1.0.2 and use Pacifist to extract ATIFacelessFlash.app and ATIROMFlasher.kext from it. This will be used as an OS X native ATI video card flasher for doing the firmware update.
· Acquire the appropriate firmware. I used sapp-512-4870.rom from this MacRumors: Forums post. If you don’t have a 512MB Sapphire ATI Radeon HD 4870 you will likely need to find another or make your own firmware image.
· Remove all the .ROM files in .../ATIFacelessFlash.app/Contents/Resources and put your .ROM file in there.
· Ensure that ATIROMFlasher.kext will load. The command sudo kextutil -nt ATIROMFlasher.kext is useful for this, and you’ll likely have to do sudo chown -R root:wheel ATIROMFlasher.kext and sudo chmod -R 644 ATIROMFlasher.kext to get it loading.
· Once the .kext is loading and ATIFacelessFlash.app is prepped, shut off the computer, move your old video card up one slot, and install the new one in Slot 1 as shown in this picture.
· Boot the computer with the monitor connected to your old video card. Load the kernel extension for the flashing (sudo kextload ATIROMFlasher.kext), then run the flash utility: sudo open ATIFacelessFlash.app.
· Shut down your computer, pull the old card, and boot up with the monitor connected to the new one. Everything should work great, and you should now have an ATI Radeon HD 4870 for Mac.

After the flashing is done, System Info showed the following under Graphics/Displays:

ATI Radeon HD 4870:
  Chipset Model: ATI Radeon HD 4870
  Type: GPU
  Bus: PCIe
  Slot: Slot-1
  PCIe Lane Width: x16
  VRAM (Total): 512 MB
  Vendor: ATI (0x1002)
  Device ID: 0x9440
  Revision ID: 0x0000
  ROM Revision: 113-B7710C-176
  EFI Driver Version: 01.00.318

Now that the upgrade is done I can run Google Earth with all the quality settings turned up. I also did a quick compare with two graphics benchmarks, CINEBENCH and OpenMark. With the old card on CINEBENCH I got a score of 3380, and with the new one 5427. Under OpenMark, which seems to test OpenGL, I went from a score of 8520 to 22579.

Having a fan the new card is slightly louder than I’d like, but I was a bit spoiled before with the old fanless card. I’ll try and investigate a way to quiet this one down, but all things said it is still quite quiet. If it ends up being a bit much I can always sell the card with its Mac firmware upgrade for at least as much as I paid.

If you’d like to see a few more pictures, they are all available in this album entitied ATI Radeon HD 4870 in Mac Pro.

New Hooks In Closet

After yesterday’s wood shaping, some paint, and $24 in hooks my closet has eight new points from which to hang clothing. This all started when Danielle wanted more places to hang hoodies in my closet. Finding a suitable blank space of wall, some spare poplar from work being done around my sister’s house, and suitable hooks at Home Depot I set to work on things.

At $3.99/ea the hooks were a bit pricey, and my can of pure white paint had rusted so I had to buy a new one, but I’m quite content with how it all came out. It fits the space needed and with the hooks screwed into the poplar and the board hanging off of the drywall with toggle bolts it’s quite solid.

River Bends Trail Closed?

Tonight I fitted my bike with a 185mm front rotor (Avid G2 Clean Sweep; upgrade from 160mm), so I set out towards River Bends to try both it and a new (to me) CamelBak Podium bike bottle. For some reason both the paved and dirt paths through River Bends were closed off, leaving me no place to go. I continued on past the closed sign on the paved path for a bit, but just as my light was illuminating some heavy machinery I heard a loud CLUNK come from it, similar to a door latch, so I turned and headed back. I’ll try and remember to call tomorrow and see if I can get some information about the construction.

Being only a few miles into my ride I considered heading up to Stony Creek for some night time single track riding, but as it was getting late (just before 9pm) I instead headed over to downtown Utica, over to Clinton River Park, through the park’s paved path to Clinton River Road, out to Schoenherr, 19 Mile to Hayes, then back home.

During this time it seems that the rotor has begun bedding in and starting to work better. Due to its larger diameter I’ve found that I get an occasional rubbing / chirping sound when turning tight corners. So far it seems that this will work out well, and hopefully it won’t fade as fast during extended bits of downhill stuff, which is a problem I was particularly noticing while riding the North Country Trail (NCT) over Labor Day.

The CamelBak Podium bottle also worked out very well. I’ve been having a problem with HEED, my preferred electrolyte / sugary drink while riding, leaking out of bottles and getting on my frame. Even worse, when on the NCT enough spilled that it dried on the shifter cable guide, sticking the cable in place, and making shifting very difficult.

After reading a bit of Fat Cyclist’s blog I’d found that he particularly liked these bottles, so I’d wanted to give one a try. Due to a series of interesting circumstances I ended up with a barely-used one yesterday while cleaning up the trail, and I decided to take it home, wash it out, and use it. While I only took a short ride on relatively smooth surfaces (save for a few curbs and potholes and hopping random things), I had no problems with leakage. Liquid flowed quite rapidly through it when squeezed, and it fit snugly in my bottle holder. The wider-than-my-other-bottles neck also made pouring in a scoop of powdered HEED very easy. I think I might have to get another one of these.

If you’re interested, here’s a few cycling-related photos from the past week or two:

· Fern-lined downhill part of the NCT. Riding up this was terribly hard.
· More fern-liked trail along the NCT, this time in a nice stand of trees.
· Inside of the tent where I slept over Labor Day at my grandparents’ house.
· Bob trying to hit me in the golf cart that we had for setting up the Addison Oaks race last Friday.
· Cones, set up to divide the two-way paved path and bridge connecting the single track with the start/finish line.
· A very dirty Rob with a bent-up hand and scraped arm after a fall on one of the very last turns at Addison Oaks during the race.

Bus Pirate v2.go LEDs (and other Moblog Photos)

Today I finally got to poking around with the Hack A Day Bus Pirate v2.go. It’s a a nice little debugging tool which shows up as a 115.2k serial terminal via USB, and allows one to send and receive a bunch of different serial protocols to devices for testing. However, the LEDs on it are far, far, far brighter than they need to be. At my normally-lit desk in a normally-lit office, they are glaring. I’m going to consider replacing them next time I place an order from Mouser or Digi-Key.

Here’s some other recent moblog photos:

· Toadstools on the mountain bike trails at Bald Mountain South Unit.
· This morning’s coffee is made in a moka.
· Bloody nose pickings wiped on the mounting bracket for a urinal partition in one of the bathrooms at work.
· My sister’s dog Molly laying on the back porch at my parent’s house.
· Joy’s mom’s fruit Extra Easy Fruit Cobbler recipe.

Fox 32 F100 RLC on 2008 Specialized Rockhopper M4 Frame

While Danielle was off with two of the other people on her Breast Cancer 3-Day team walking ~16 miles, I spent most of Sunday working on my bike. After the very muddy Tree Farm Relay the day before my bike needed to be washed, and I had a new fork to fit.

For the first time I actually disassembled the entire bike, removing everything except for the bottom bracket, front derailleur, and derailleur hanger. Everything was then thoroughly cleaned, greased as needed, and put back together. At the same time as this a Cane Creek S-3 headset and the new-to-me Fox 32 F100 RLC fork were installed.

The undamaged Avid Clean Sweep G2 rotor (from leftover from the replacement of the brakes post-comically bad ride) was also fitted to the front in place of the roundagon that came with the BB7 and I’d fitted in July of last year. I’ve heard that they tend to stop better than the smoother roundagons, and after some brake clogging problems during the race, I figure it’s worth trying.

The steerer tube on the new fork was just a little bit longer than my old one, but I figured it was best to leave it be and just throw a spacer on top of the stem. As seen here it’s really not too bad looking, even with the particularly tall Niner YAWYD stem cap. I’m not sure I care for the carbon fiber look either, but I don’t think it’s terribly noticeable. Still, I can only hope that in a few years the Asian manufactures will do the world a favor and start using opaque epoxies when working with CF.

The shifter cables were replaced, time was spent adjusting the fork to both factory defaults and a reasonable sag for my weight (100psi, for reference), and a few test rides around the neighborhood were taken. Now to get out and do some single track riding and test it out. Hopefully this will happen tomorrow.

Here’s all of the pictures taken of my bike today, in case you want to see how it now looks:

· My bike, a once-was 2008 Specialized Rockhopper Disc, after being cleaned up and fitted with a 2008 Fox RLC fork and Cane Creek S3 headset. (Note the terrible crank / downtube positioning. This is awful composition.)
· Detail of the Cane Creek S3 headset and carbon fiber spacers. Since the steerer tube is a bit long and I didn’t want to cut it, the top cap sticks up a bit.
· 2008 Fox 32 F100 RLC fork and Cane Creek S3 headset installed on my 2008 Rockhopper Disc.
· Clean rear drivetrain after disassembly and chain replacement. The mud from the Tree Farm Relay required that everything receive particular attention.
