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.

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.

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.

A real guitar hero?

Sunday, November 30th, 2008

I had an acoustic guitar a good many years ago. I didn’t play it much because it simply made too much noise. I plucked it with my fingers to keep the sound down, but hey … ouch. I still want to play around as a hobby (not a rock star or anything). So I’ve been thinking about getting an electric guitar every now and then. Since the body is solid, the strings hardly make any sound. The popularity of these video games “Guitar Hero” and “Rock Band” has really started to spark my interest as well. I avoided the games simply because they are not real. I feel I would end up learning the wrong thing or some odd fingering techniques. So I started looking into a few things. For one, an electric guitar and an amp runs about 100 dollars on ebay. I’ll dig deeper to find something cheaper, but that looks like a starting point. The other thing that I found was something called Guitar Rising. Rather then using a plastic video game guitar controller, you plug in your electric guitar to the computer (or a microphone) and strum away. It looks like the same concept of the regular video games, except that you can actually learn something form it. Unfortunately, it’s not available yet. Go figure. However, it gives hope into learning how to play a guitar well, and having fun at the same time. Nice way to measure accuracy and stuffs. I also found a site, GuitarGames.net that helps with some simple guitar games.

Monkeying around with Tagging

Saturday, October 25th, 2008

At one time, all of my 3000+ MP3 and AAC files had been tagged with ratings, album artwork, categories, etc. This was mainly done using iTunes over a long period of time. I started looking around and found a better tool to take care of the tagging and quickly identify witch files are missing specific tags. MediaMonkey is my new hero. Forget about iTunes. This software has the ability to fetch artwork, track names, artist, label, year, etc. direct from Amazon. I have a choice of many different amazon sites to choose from as well (UK, Germany, Japan, etc.) which comes in handy for imports. The manageability of my music within the product is great. I’m able to view music by album, artist, Composer, Genre, Year, etc. The one that I love is the ability to list music without album artwork. I have about 1644 files left to tag. It also has the ability to rename the files on my computer and network drives according to a format that I specify. I prefer <Album Artist>\<Album>\<Track#> – <Title>. The software is free, but a paid version gets you a bit more features. I’m debating on getting the lifetime membership so I’ll be privy to all future updates. The one thing that it seems to be missing is the ability to detect (or even host) media servers on my network. At this time, only the PS3 and Windows Media Player are able to detect the media server. Who knows… maybe sometime in the future that capability will be available.

Back on ACID

Friday, October 24th, 2008

I started digging around in a few boxes hoping that I could find my CD case of software. I knew that my ACID loops were in there. If I could find them, Then I could start playing with the trial version of ACID Music Studio 7.0. The trial comes with no sounds at all to play with. It is practically useless. I found the software and even better – I found my old ACID 2.0 Music software. Woo Hoo! I spent forever and a day trying to figure out how to register it since the original developer had sold the software to Sony. The codes that I had turned out to be bogus when I tried to register with Sony. I finally found out that I could associate my old email account to reclaim the codes. It’s a good thing I reactivated that email address a few months ago. The thing keeps paying for itself over and over again. It sent an email out to my old email and then I was able to reclaim the old Acid software code. Woo Hoo! So now I get to start playing with loops and see if my interest is involved enough to actually upgrade to version 7 or not. At least this way I don’t have to worry about time limits and I can actually produce something too.

The delay of my little big planet

Wednesday, October 22nd, 2008

Today I discovered what the rest of the LBP fans probably know already. The game has been delayed not by the developers, but by the distributor – Sony. The problem boils down to one of the songs played in the background of the third planet. It refers to the Qur’an quoting passages from religious literature. I visited the songwriters myspace site and listened to the song in question, Tapha Niang. It begins with a peaceful instrumental. When it does get around to the lyrics, it sounded to me like something from Africa. In fact, the world with the song has a Safari theme to it and is called “Swingin Safari”.

I am not offended by the idea that the lyrics are there. However, Sony pulled the plug to avoid any legal issues with offending Muslims. There have been a few arguments from different viewpoints. Some people say that they would rather choose not to buy the game rather then to restrict the freedom of expression. However, business is business. The game is delayed until at least the 28th of October, and I’m seeing chatter that it may be delayed until the first week of November.

I just wanna have fun already.
