Case change for GPS data logger

Ragtop · 2012-04-09 08:25

Ok. not much of a project, just changing cases, but I don't remember putting this project up here so in the process of
changing it over I thought I would go over the details of this GPS data logger that writes a KML track file to use with Google Earth.

My casing skills may not be stellar, but they are improved from where I started. I have got to work with the table saw and sander, as I am now trying to squeeze
all the electronics into the lid of the new case.

Did I say "Not much of a project"? A month ago?

I ran into a snag as I butchered my microSD adapter, but finally got all the hardware
working again and hope to go over some software updates in the next video.

Umm, video of me editing my program makes my past videos seem as exciting as Bourne Identity in comparison.

So until I get finished with that here is a kml file that it kicked out today and a clip of it on Google Earth. Didn't get
good readings with the GPS as I had unit in pants pocket. Usually does better in backpack.

Thomas,

How are your regulating the voltage in your logger?

I had a GPS logger that was working pretty well until I added a switching regulator in order to use the battery power more efficiently. The switching regulator seriously interfered with the GPS reception.

A had a similar problem when I tried to use a LCD with a backlight. The backlight voltage booster, interfered with the GPS signal.

Apparently there are ways of shield these noisy items but I haven't learned how to do it yet.

I did purchase some copper tape from SparkFun in hopes of making a metal cage for the noisy items. I haven't tried using it yet.

With a 3.3v zener diode. The 3.7v lipo battery didn't give me any drop-out room for a regulator. Used it for a year like that without a problem on the Propeller Proto Board bypassing the regs on it.

Does make me wonder if I could get more interference now from the other components as I now have everything crammed together. Copper tape going on the wish list.

I got my 3d models for the hiker, bike, and car from various free places to get 3d studio max .3ds models online and then imported them into Google's Sketchup and exported them as .dae files.
I store the .dae files in the main directory of the micro SD card that I write the tracks to. The flag pole for when the placemark button is pressed I made in 3d studio max.

Ragtop, Nice setup, I really like the portability of the case you are using. I have a similar setup in a Polycase VM-36 enclosure that uses a Gadget Gangster USB (non-uSD) board (prototype predecessor to the Gadget Gangster PP-USB), the same GPS, and the uOLED-128-G1 display. After seeing this, I think I will change to a PP-USB board to add uSD, and then do some KML logging as well. Do you have the code you are using posted anywhere?

On a side note, if you wanted to reduce your size a bit more, you could take one of my M44D40+ modules and my micro-microSD adapter to get a PCB footprint about the size of a DIP40 chip.

OMG, I would have room for all sorts of stuff using your M44D40+ board.

Code is coming soon. It is really nasty, but working. With the change, I wanted to fix some of the things I was doing.
1. Now it checks to see if file exist, so as not to overwrite previous tracks.
2. It now closes and appends to file, which gives me a better chance to recover data if something crashes. I was leaving file open for the whole write
3. Not a fix, but added a new placemark function for the the added button that plants the flag.

I am working on the last addition. I wanted a larger clock as I am using this for video and the small time numbers on the animation slider don't show up. So I am overlaying a flip-number clock
to the bottom right of the window.

Got a lot of movement considering it sit on my computer desk the whole time, but the clock overlay is working!

This is a zip file of the four models and clock number images. They need to be in main directory of micro SD or if you move the track files to hard drive, you need to copy these files to the same directory.

Ragtop · 2012-05-20 06:44

This is the zip file for my prop program and all the included objects.

Only problem with a custom build of a case that you have one of is breaking said case. I broke the hinge that I have been able to fix with a zip tie (third line of defense behind duct tape and hot glue).

But it got me searching the internet for the cases and I finally found a source for them. Beach floats

I still got to find a place to just get a few.

Duane Degn · 2012-05-23 08:49

Thomas,

Sorry to hear about the broken case. It's a pain when something like that happens.

I found a place on ebay that will sell just one. I think $12.50 shipped is a bit excessive.

I just requested a quote from the place you linked to for unprinted totes. I also asked if they'd sell just 100.

If I buy some, I'll sell you part of my order if you want.

Ragtop · 2012-05-23 11:33

Yeah, now knowing what to call them, I found this one for ~10 which is a bit high. http://www.ebay.com/itm/120689791985?_trksid=p5197.c0.m619#ht_1082wt_1135

I think I might could get a used otter box for that range which would be a stronger box.

Getting a few of these at around the wholesale price would be great!

If you have an REI store nearby, check them out. They have a pretty good selection in a few different departments in their stores for waterproof cases.

Ragtop · 2012-06-26 18:18

Not sure if it is the same size, but it looks like the same case. Electronic Goldmine is giving them away for free with 25 dollar order.

Ragtop,

I was trying to compile the code you posted on 5-20-2012, but I get an error on line 295. Tried it with PropTool and BST.

Thanks!

Jim

PS Nice Work on all the extras!

Duane Degn · 2012-07-11 10:27

Thomas, I don't suppose I could talk you into making another video showing off your completed project?

I'd really like to see how it turned out.

BTW, after you mentioned OtterBoxes, I ordered a several different sizes. They're really nice little water tight boxes. I might move my GPS project into the smallest one.

That should be method call mainprogram. I must of not saved it after changing it.

@Ragtop

Kinda what if figured. I had replace main2 with main program before and it complied correctly.

Now to build the hardware!

Thanks!

Video of the datalogger in action. Promised this one a while back but haven't been
getting out to put it to use, so was waiting on next 24 hour scenario paintball game
to do this video.

TMAC1 · 2012-10-02 06:11

or you could try aluminum foil, I think that works too (plus it's cheaper)

Ragtop · 2012-10-02 09:41

I goofed up the last video. The device doesn't make a video it makes an animated KML file for Google Earth.
I convert that to video using a screen capture program called FastStone.
