GPS Conversion Utility

Saturday, December 27th, 2008

Last night I was preparing to load up a lot of GPS markers into the Garmen eTrex and Magellen Maestro 4040. The problem I had was that the Geocaching site only allowed me to download a LOC file of about 20 locations. With a 25 mile radius, this left me with almost 90 files to combine into one. On top of that, the Maestro doesn’t understand LOC files, and the eTrex didn’t come with software to import/export waypoints.

The software for the Maestro was able to understand GPX files. I created a utility to search for all LOC files within a folder, combine them, and save them to a GPX file. It took me a few tries before I got the format setup correct. Once it was all setup, I was sailing fine and saw all the points show up in my local area on the Maestro.

I then found some software called Expert GPS that claimed to work with the Garmin eTrex (but not with the Magellan Maestro). Much to my surprise, I was able to import the same GPX file and transfer the coordinates to the eTrex using the 30 day trial software. I had a limit of only 500 waypoints, so I had to cut the list pretty short. Switching between types of data to display continued to make the Expert GPS crash.

With both GPS devices in hand, my nephew and I headed out to find some treasure. We drove around into dead ends and discovered a bit of my neighborhood. When we got out to walk around, a police officer pulled up behind us with lights flashing. I was a bit confused until he started pointing to six guys driving around on ATV’s up by the power lines. I assume he thought we may have been with them at first. He got back in his car and we walked off.

We headed over to GCQVYX with the only information of “Lego Land Pearl Jam”. It didn’t make much sense. It took us over to the side of a local Wall-Mart. We saw a guard rail, some trees, and the pole to a road sign that must have been taken down recently. We spent about 20 minutes, but couldn’t find the whereabouts of the cache. We decided to head back and grabbed a bite to eat at Burger King.

Looking at the details after we got home, it appeared that the guard rail was the main thing we should have concentrated on, and to look for a micro cache. In turn, it would have led us to a second cache. I may return tomorrow to take a second look. There are a few problems with what we have available. First, the eTrex is often only good to about 20 feet at best (it’s old). Next, waypoints that I saw in the Magellan didn’t show up in the eTrex (500 limit). Maps of roads in the Magellan is severely out dated, or were just never entered. Even main streets are not present. And last – the lack of details. I may start looking into creating a lot of text files (one for each cache) and saving them to my phone. This way, we can look up the details in a text file when we arrive at each cache to get some clues and background information.

The optimal solution would be to just get a new GPS that can hold more waypoints, be a bit more accurate (within 3 feet), contain current maps, and allow me to import topographical, arial, and/or street maps of the area. Something like this would be around 300 to 600 dollars (ouch). Since I’m broke, I’ll make due with the toys I already have.

The case of the missing dime

Friday, December 26th, 2008

Money is tight at the moment so I went hunting around the house for loose change. I was interested to determine how accurate the Coinstar machines are, so I decided to count each denomination and record how much the grand total would be. I worked it out the the following.

Coin Inventory
Coin Quantity Value Weight
Quarter 274 $68.50 1,553.58 g
Dime 270 $27.00 612.36 g
Nickle 110 $5.50 550.00 g
Penny 649 $6.49 1622.50 g
Total 1303 $107.49 4338.44 g

That works out to roughly 4.3 kg and converts to just under 9.6 pounds. My nephew and I dumped all the coins into a bag and headed over to Wegmans to cash in/out. To get free coin counting, we looked at the different gift cards available, but did not find anything of interest. A gift card for the store we were in would have been perfect. We decided to get cash with a service charge of 8.9%.

All the numbers came up fine except for the dimes. It short changed me by 10 cents. My nephew had a dime with is spare change and threw it into the machine. With a service charge of 8.9%, we were able to get a coupon for 97.92. Great, I just paid eight cents for nothing since I’m getting 92 cents in change back. The cashier was a bit confused with our coupon. He entered it into the system, but the computer wouldn’t let him process it. I had noticed that the coupon stated that a manager signature was required. The manager who came by agreed with me and said that the cashier did everything correct.

When I got home, I started moving the original containers for each coin to the side of my desk. I noticed a rattling in one of the boxes and found the missing dime! I showed it to my nephew and he got a silly look on his face as I handed him the dime.

Traveling GPS

Wednesday, December 24th, 2008

Shortly after purchasing an SUV a couple years ago, I also purchased a Magellan Maestro 4040. This thing has been very handy with traveling directions. After playing with my Garmin eTrex tonight, I started looking at what I could do with the Maestro in regards to Geocaching. The benefit of course would be that it would help me better plan where I should park before walking into the woods. In addition, the map capabilities would help me greatly understand where I am. Even with a GPS, I have gotten very, very lost due to one-way traveling (steep slopes / deep rivers) only to find myself coming back to civilization very far from where I originally started out. A GPS with map software built in – priceless.

I couldn’t find a way to enter GPS coordinates accurately except by touching the map far enough from roads. I updated the firmware and still didn’t have much luck. I downloaded something from the manufacturer called VantagePoint, but it was incompatible with the hardware. Afterwards, I learned that the device was supposed to come with a disc that contained Magellan POI File Editor. I had no idea where the disc was, and the manufacturer wasn’t making it available either. I found a post that helped people to create a custom POI file for Magellan GPS in which it had linked to the Magellan POI File Editor. One of the links were broken, but the other actually downloaded a binary file.

I got the program running. At first, I was having trouble trying to figure out what type of format the longitude/latitude was supposed to be. After a few tries, I found that it expected mostly decimal, but only using unsigned numbers where N/S E/W would be used to indicate the sign instead. What a pain. Anyway, I got past that and the next step was figuring out where exactly I was supposed to save the new MGLN file. The correct location is G:\USR\CPOI\file.mgln, where “G” is the drive that it attached as to the operating system.

Once the file was loaded into memory, the trip planner created a route to the nearest place to the cache with a flag. Then a trail was routed from the flag to the target waypoint.

I think this will be very interesting to play with my nephew. He can use the Garmin eTrex GPS, and I’ll use the Magellan Maestro 4040. Once we get in really close, he can take over for more accuracy. The eTrex has a compass that can point to the waypoint and tell us how far we are by feet. The Magellan Maestro will simply tell us that we have arrived.

The Asphalt Mile

Wednesday, December 24th, 2008

Every now and then I talk a walk around the neighborhood to get some exercise. The fresh air helps a bit as well. I was curious as to how long the walk is in distance. It occured to me that I could probably use a GPS device to track a trek. I have a Garmon eTrex that I used to use for Geocaching a few years back. I discovered it’s whereabouts the other day when going through a few boxes in the back room.

The trip worked out to be 1.16 miles in length. It took me 24 minutes with a moving average of 2.9 miles per hour. Even my wife was a bit surprised at the distance. The two of us thought it was much shorter. It worked out that the back half of the trip turned out to be a greater distance then the first part.

The accuracy of the signals turned out to be between 18 and 32 feet due to the clouds covering the area. I wonder how much of an effect this has on the reported distance. The maximum speed reported was 10.6. On foot, I doubt I was moving this fast. I was casually walking the whole time. The big hill in the back half slowed me down even more.

Maybe I’ll start up my hunt again soon. I see a few new caches near my home. My geocache profile could use a little bit of updating. I still have a few bugs that I need to release into the wild. It would be something I could log into my Wii Fit as well.

Open Source Guitar Software

Wednesday, December 24th, 2008

I am still on a hunt to find useful programs to help guide me to learning how to play the guitar. Today I started going through open-source software for Guitars on SourceForge. I haven’t tried them all out, but these are the ones that interested me.

  • Absolute Guitar Trainer: Absolute Guitar Trainer (agtrainer) is the first interactive electric guitar trainer capable of recognizing the sound from the user’s music instrument (basically an electric guitar) and use it to estimate the user’s advancement.
  • CP Guitar Effect Proccessor: CP-GFX is simply a Cross Platform Guitar Effect Processor. The aim of the project is to create an extensible and easy to use program which is easy to port to different platforms an operating systems.
  • GNUitarra/Guitar helper: GNUitarra is a light-fast all-in-one helper for the guitar player. Has more than +4000 scale types, +60 chord types, +60 string instruments (i.e bass). Can automake solos, learning excersises, etc. Works even in a 386!
  • DGuitar: a Guitar Pro viewer, player: DGuitar is a Guitar Pro (*.GP4,*.GP3,GTP) viewer and player that works under Linux, MacOs, Solaris, BSD, Windows, or any other operating system with Java Runtime 1.4.X.
  • GNUitar: GNUitar is guitar effects software that allows you to use your PC as guitar processor. It includes the following effects: wah-wah, sustain, distortion, reverberator, echo, delay, tremolo, vibrato, and chorus/flanger.
  • Guitar Scale Assistant: Guitar Scale Assistant is a java based guitar application. This application allows guitarists to display, create, hear, and search for scales based on chords, progressions, note sequences, or names. A useful tool for guitarists at all levels.

Little Big Star

Tuesday, December 23rd, 2008

In my search to find computer programs that are interactive with “real” guitars (Guitarware?), I have found Guitar Rising, and GuitarGames.net. Today I just found another one that is free (for personal use) and available rite now called Little Big Star.

I downloaded the beta and quickly discovered that it wouldn’t run on a 64 bit operating system. The fix is simple and I left instructions with the author in how to fix the problem. Hopefully the next release will have the fix in place. As for everyone else who runs the application, I keep seeing good feedback. The visuals are starting to look like the actual Guitar Hero and Rock Band interfaces of the popular video game consoles. In fact, the software states that you can even hook up one of the video game guitar controllers and play with that instead of a real guitar if you like.

The software has a few problems with chords. This isn’t surprising since Guitar Rising has been delayed until 2009 for the same issues. (This is cutting-edge technology). One trick that the author is experimenting with is to dampen the guitar using a sock at the base of the strings so that the notes do not interfere with each other. It appears a bit odd to me, but then again – I don’t know much about guitars in general.

Hopefully Little Big Star and Guitar Rising will really help a lot of folks (including myself) to learn guitar. The author of Little Big Star is learning guitar as well and has identified some interesting techniques to help people learn songs. One mode is to wait for someone to play a note before advancing to the next note. Both games offer the ability to slow down the speed of the songs. This is really going to be an exciting time watching the technology jump from video game simulation to real-world teaching tools that are fun. Guitar Rising comes with songs, but LittleBigStar does not (to avoid copyright issues).

A trip to Guitar Center

Tuesday, December 23rd, 2008

I met my brother over at Guitar Center. We saw a few guitar kits. The website seems to have more choices then what we had seen on the site. Some kits appeared to have the same guitars as others. We saw slight differences in the guitar itself, but the price tag between two kits was over 100 dollars. I assume that it had something to do with the amp included. The expensive one had drums and loops built in so you could play along. It reminded me of how a lot of keyboards have similar features to start up a tune with a beat while you can play along.

I didn’t buy anything, but I have a better idea of what I am going to get. Fender appears to be the popular brand with these kits with their strat. It’s a pretty popular model in general. The only real options between them appear to be more of the amp included in the kits rather than features on the guitars themselves. I saw one with an extra coil pickup, and another had the same number, but laid out differently. That appears to be the physical difference that I could see. I’m leaning towards a metallic blue body.

Lucas came with an interest in keyboards but started leaning towards getting a guitar at the end. He’s been getting an education on guitars from a friend of his in regards to model shapes, materials, quality, etc.

We looked around and found a few other nick-knacks. The two of us left without any new guitars, but we now have a few plans and a better idea of how much to budget for a guitar.

More Guitar Research

Monday, December 22nd, 2008

I talked with my brother tonight about my interest in an electric guitar. Ebay is still selling the ones I found for 100 dollars. We saw that they were Bridgecraft guitars, model unknown. All Bridgecraft guitar reviews on Harmony Central turned out to be very bad. Some people complained about knobs, others said that the tension in the strings actually warped the neck.

I talked about a guitar I found at my local Sam’s club running for 200 dollars. We found the Starcaster Strat Electric Guitar Pack on the Sam’s club website. The brand was seemed to be “Starcaster”, but I had found that Fender also sells something by the same name on Amazon (180, vs Sams for 200) Fender Starcaster Strat Pack Electric Guitar with Amp and Accessories. The concern was that we were not sure of the brand of the guitar, or how “cheap” it was put together. After seeing the reviews from the Bridgecraft guitars, we were a bit put off. We also found a few cheaper value packs as well such as the Silvertone SS11 Electric Guitar & Amp Package (Amazon: 170, Sams Club: 140). Again, we lack knowledge in the quality of brands and materials.

Last, we looked at Guitar Center. We found a few value packs that included a guitar, amp, bag, strings, tuner, pics, etc. The prices seemed to range from 175 to 770 dollars. We were looking at the 200 dollar ones the most, but Lucas pointed out that Laguna Ultimate Rock Electric Guitar Pack with Line 6 Spider III 15W Amp would probably be more optimal for me. Money … anything that is reasonable for starting out seems to be a bit more expensive side then I preferred. The difference with getting guitars here is that guitar center is a more credible place to buy them. In addition, we agreed to meet tomorrow and take a look at the guitars in person. He mentioned that we would be able to pick them up and get a feel for the weight and length and may form different opinions.

I am still not ready to purchase a guitar just yet. I’m waiting for the money to be available before I go into it. However, the outlook doesn’t look great. I wanted to get a really cheap guitar to play around with. I don’t plan on forming a band, performing gigs, or going anywhere with it. This is primarily for me to simply play around as a hobby in my spare time. In addition, I don’t know if I’ll lose interest after a month. I tend to get more anxiouse as I see that this is going to cost more then I had planned. Lucas mentioned that I could also go the way of renting a guitar, or putting it on a credit card. I’d prefer to avoid introducing a new monthly bill to my budget at all costs.

The cheapest route appears to be bad in any way that I look at it. Even good used guitars are very expensive. It is hard to imagine why people would pay thousands of dollars for a guitar. Why is one $7,000 where another is $300? Is it simply brand recognition?

We had talked about the game that I had found, Guitar Rising. He appeared a bit interested in it as well. The games website still says that it will not be available until 2009. Lucas appears to think that BestBuy, or other stores with computer software (including Guitar Center) should be selling software with feedback as you play. I have searched, but the closest that I could come up with was software for editing sheet music or providing videos of music lessons. He also mentioned that the On-Demand channel for Comcast had free music lesson videos for Guitars. I was curious and looked it up. Sure enough there were a ton of them, all free to watch. Awesome!

My brother also has a friend who runs a pawn shop. Unfortunately, the guy is a guitar collector as well. Anything that comes through with a good deal, he picks up for himself. However, maybe he can pass on some advice for a beginner such as myself on what to look for.

Don’t fall for it

Friday, December 5th, 2008

You know, I am sick of people taking advantage of the financial hardships that people are going through. It has really made me skeptical of just about every scam I see on the net. I saw one advertised on the front page of MySpace – Kevin Gets Green (Just search for it on google). The guy touts that you could make a few thousand a month for just a few dollars to cover shipping and handling.

So, what are the flags to look for?

  • Money! Apparently the scam requires some form of payment before you learn what it is
  • No hints or description of what exactly he does
  • Comments/Testimonials without a comment form, timestamp, or link to authors of each comment. In other words, he probably just made up the testimonials himself.
  • Only one reply by the author with a link to a credit card scam
  • Author claims they are skeptical of other programs, but gives no reason why you shouldn’t be skeptical of them

So, I decided to click on his first link – google cash. Immediately I saw some small print on the page. The one dollar isn’t for shipping, it is for “processing”. Also, after 7 days, you will be billed 11.95 per month. After 14 days, another service (identity theft/fraud protection) will charge 4.95, and then after 21 days, it will charge 9.95 per month. Now isn’t that a sneaky? So here are the obvious red flags that I saw on the page:

  • one very loooong page that describes everything except what you do
  • A video (automatic playing) of a sales rep “feeling your pain” and looks like he is part of the page
  • Time limit of just a few hours before the offer is gone
  • More testimonials from people who don’t exist – interesting text at bottom though “*Results not typical.
    Individuals has been remunerated.” – which means, this guy has been paid to say this.
  • Any attempt to leave the page opens a message box asking you not to leave. In addition, a pretend telephone operator shows up in a chat window for you to talk with

I didn’t even bother looking at the link for government grants.
