One of the things we need to be able to do is receive the balloon's GPS transmission on a laptop to plot its location on a map. To do this we use a Radio Shack scanner to pickup the transmission and connect the scanner's audio output to the microphone input on the laptop. Next we use a program on the laptop called "AGE Packet Engine" to convert the audio input to digital APRS packets.<br /><br />Now this was all working back in November when we were set to launch but for some reason it was no longer working. After about about 90 minutes of fighting this program I finally noticed a blurb in the instructions that said "If all else fails, delete the port*.ini files and the agwpe.ini file in the AGWPE directory". That did the trick!! :) The instructions for this program are at <a href="http://www.kc2rlm.info/soundcardpacket/">http://www.kc2rlm.info/soundcardpacket/</a>. Now that this is working we can plot the balloon's location with another program called "AGW Tracker". AGWPE and AGW Tracker are both free and are available at <a href="http://www.sv2agw.com/downloads/">http://www.sv2agw.com/downloads/</a>. Here are the settings that we ended up using for AGWPE:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPbpbernLzZW1-Kzn6Gsdu2DL9kFrJtl210a316_L-Z96ywN-TqhGRT0Nav1p821OFLzTg-_YWoJqo0lsTO4CnmmmArc-3F453vf4UQhLrASXj5y6dHp3IPd4pWMg8modFKUF9tf-EZGM/s1600-h/agwpe_setup1.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPbpbernLzZW1-Kzn6Gsdu2DL9kFrJtl210a316_L-Z96ywN-TqhGRT0Nav1p821OFLzTg-_YWoJqo0lsTO4CnmmmArc-3F453vf4UQhLrASXj5y6dHp3IPd4pWMg8modFKUF9tf-EZGM/s320/agwpe_setup1.jpg" alt="" id="BLOGGER_PHOTO_ID_5232291094258917474" border="0" /></a><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgj1HUluuIBmevp8O3dQnBus6B_brD15LwiYgHpT0KqqIZ4g8HOOcaOAyxtMP8p90heh5-X4knpgy8hsfaydjJp4Jys_673zCHIemRdVdNqe2rr1YNDVc5KoswV349hgUyAYNHQdOotr08/s1600-h/agwpe_setup2.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgj1HUluuIBmevp8O3dQnBus6B_brD15LwiYgHpT0KqqIZ4g8HOOcaOAyxtMP8p90heh5-X4knpgy8hsfaydjJp4Jys_673zCHIemRdVdNqe2rr1YNDVc5KoswV349hgUyAYNHQdOotr08/s320/agwpe_setup2.jpg" alt="" id="BLOGGER_PHOTO_ID_5232291323908921762" border="0" /></a><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEim6_C_91tTN_hfCvQj9L4NpIy5UhJHb5BotLJlkWtkhc713vtzkJwmMC5YVSlUCVaHie2EHiX87LnL99yKvksWYlhusN0oFGOP_0UeO7JKbr13Je9_SaezwZYTXIlwy3UC8xCIqJtposI/s1600-h/agwpe_setup3.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEim6_C_91tTN_hfCvQj9L4NpIy5UhJHb5BotLJlkWtkhc713vtzkJwmMC5YVSlUCVaHie2EHiX87LnL99yKvksWYlhusN0oFGOP_0UeO7JKbr13Je9_SaezwZYTXIlwy3UC8xCIqJtposI/s320/agwpe_setup3.jpg" alt="" id="BLOGGER_PHOTO_ID_5232291435600085954" border="0" /></a>dwalton76http://www.blogger.com/profile/01231435969332456287noreply@blogger.com1tag:blogger.com,1999:blog-5480060546986548590.post-84560962967091634752008-08-08T18:36:00.003-04:002008-08-08T18:53:47.963-04:00New launch site<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgX9q6pWQcJDnGbKhExjsVTC3H4B_I2mGDQXbxu4JYAWu-NF4i5XdpwWJ-lej777BI4pryE7gMg_cQpP42QX5-_KKuilEX6DNNyEdWlO_9O3yf1Zqrf4S4S64Id-hJlkKd0kG6F66jGN78/s1600-h/balloon_track_aug_06_2008.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgX9q6pWQcJDnGbKhExjsVTC3H4B_I2mGDQXbxu4JYAWu-NF4i5XdpwWJ-lej777BI4pryE7gMg_cQpP42QX5-_KKuilEX6DNNyEdWlO_9O3yf1Zqrf4S4S64Id-hJlkKd0kG6F66jGN78/s320/balloon_track_aug_06_2008.jpg" alt="" id="BLOGGER_PHOTO_ID_5232279686719839522" border="0" /></a><br />After months and months of watching Balloon Track send our balloon to the East out to sea we're now seeing balloon projections heading West! We've decided to move our launch site from Asheboro to Pittsboro since that is closer to home and we're no longer worried about landing in the Atlantic. We have some friends with a farm near Pittsboro which will give us a nice open area to launch the balloon and clear the trees.dwalton76http://www.blogger.com/profile/01231435969332456287noreply@blogger.com0tag:blogger.com,1999:blog-5480060546986548590.post-91768349820426276142008-08-08T09:23:00.010-04:002008-08-08T18:31:41.533-04:00It's all greek to me... using digipeaters<p><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjz5UUAjdLKDJhimLlbQtVRg9zelrUgAU5ChCNKnTtkw7sFL1kw3qFo2buOx_2yAQKeKvl5qUHdw0oyS1dbf10AFEWyL9Ic13Vj223UglU0K-_uQa-5329DLxok0bIdFMgjWbd1wb8vgXU/s1600-h/WARPED_tinytrakscreenshot.jpg"><img id="BLOGGER_PHOTO_ID_5232146029895703474" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; CURSOR: hand" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjz5UUAjdLKDJhimLlbQtVRg9zelrUgAU5ChCNKnTtkw7sFL1kw3qFo2buOx_2yAQKeKvl5qUHdw0oyS1dbf10AFEWyL9Ic13Vj223UglU0K-_uQa-5329DLxok0bIdFMgjWbd1wb8vgXU/s320/WARPED_tinytrakscreenshot.jpg" border="0" /></a><br />So we're back in the swing of things and we are struggling to figure out how to make the GPS transmit in a safe way over digipeaters so that people who cannot come along on launch day can track us. Ideally the <a href="http://www.byonics.com/microtrak/mt300.php">Micro-Trak</a> will send out the coordinates, our callsign, and enough repeater parameters to not blast the world with our traffic, but maybe cover part of NC. If that works, then people can use <a href="http://www.findu.com/">http://www.findu.com</a> to track the balloon on launch day! We could not get this working on Wed night so I called up Britt, our friend and "real" ham enthusiast for help. It turns out that the APRS powerpoint we were reading is old and crusty and that the WIDE and RELAY parameters are no longer in use. Instead there is WIDE N-n. While I'm still trying to understand what it all means, the gist of it is that larger N and n #s mean you spam the whole world with your traffic (a bad thing). It looks like the recommended parameters for a balloon or "mobile" is WIDE1-1,WIDE2-1.<br /><br /><a href="http://www.aprs.org/fix14439.html">APRS "Fixing Digipeaters"</a> is a good reference. We'll keep checking to make sure that this is right but if the tinytrack sw and the APRS websites agree that's probably right. Would be good to get a better understanding of it for my own sake though. (and other future ballooners).<br /><br />Some examples of how to use FINDU's map-near.cgi. It displays position reports known to be near a given location, which may be specified as a lat/lon, callsign, or zipcode. </p><ul><li>CALLSIGN <a href="http://www.findu.com/cgi-bin/map-near.cgi?call=k4hg">http://www.findu.com/cgi-bin/map-near.cgi?call=k4hg</a> </li><li>ZIPCODE <a href="http://www.findu.com/cgi-bin/map-near.cgi?zip=27502">http://www.findu.com/cgi-bin/map-near.cgi?zip=27502</a> </li><li>LAT,LONG <a href="http://www.findu.com/cgi-bin/map-near.cgi?lat=24.5&lon=-81.2&cnt=20">http://www.findu.com/cgi-bin/map-near.cgi?lat=24.5&lon=-81.2&cnt=20</a> </li></ul>ARWhttp://www.blogger.com/profile/04743865559533522318noreply@blogger.com0tag:blogger.com,1999:blog-5480060546986548590.post-89759553343250448872008-07-28T09:00:00.002-04:002008-07-28T09:05:20.011-04:00Launch date set...August 31st<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhHnIgu4_z1f2Vk-3Mmpkrd_MivR7Xt43-Wbd165Rrvefh-vDqJxNrtzUBzI_bBF-uIIvrNzXEt-u95x1wAGmj8BlBXTN37kEVRCvTrmnm3_v0bebM7ZaP4B5nJSirbGnJH9BxYqqSlNZk/s1600-h/projected_path_07_27am.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhHnIgu4_z1f2Vk-3Mmpkrd_MivR7Xt43-Wbd165Rrvefh-vDqJxNrtzUBzI_bBF-uIIvrNzXEt-u95x1wAGmj8BlBXTN37kEVRCvTrmnm3_v0bebM7ZaP4B5nJSirbGnJH9BxYqqSlNZk/s320/projected_path_07_27am.jpg" alt="" id="BLOGGER_PHOTO_ID_5228049308210724258" border="0" /></a>We've been slack and haven't done much with our balloon project in a while but the winds are finally working with us so we're going to get going with this again.

That seems like a long way to try to keep up with a balloon when driving on random roads and through lots of small towns. Maybe our balloon will be very cooperative and stay directly over I-40 the whole way :) If this ends up being as good as the winds get then we'll have to think about having a launch crew in Asheboro and a chase crew somewhere East of I-95. <br /><br />We'll keep checking the projected flight path and hopefully we'll be able to do a launch sometime in April or May.dwalton76http://www.blogger.com/profile/01231435969332456287noreply@blogger.com1tag:blogger.com,1999:blog-5480060546986548590.post-24376217947822230682007-12-11T22:06:00.000-05:002007-12-11T19:06:59.395-05:00Stay tuned for further developments...Having caught up on my blog reading, I realized that we haven't posted in a month. Just wanted to give any readers of this blog a heads-up that we *probably* won't be launching in the near future. I haven't run any of the weather models myself (Daniel's been doing that, while I've been working on some basic air-density models and temperature measurement devices), but the winter winds in NC are likely to carry our balloon far out to sea.<br /><br />On the temperature front, I ordered some <a href="http://www.maxim-ic.com/products/ibutton/ibuttons/">iButtons</a> to log the temperature and humidity of the balloon box, just because we can. I ordered the Thermochron (tempearture only) and Hygrochron (temperature and relative humidity) from <a href="http://www.ibuttonlink.com/">iButtonlink</a>.

For now we've scrubbed the launch. I suddenly have a lot more sympathy for why NASA is always moving the shuttle launches.<br /><br />We've also decided that in hindsight, the parachute is too large. We don't need it to land like a feather - we just need the cooler and camera to survive. Our current payload estimate is 3lbs and our chute was rated for 3.5-8lbs (R7). We'll try to exchange the chute for a smaller one - maybe something in the 1.5-2.5lb (R3 or R4) range.

These numbers are needed in order for the tool below to calculate the balloon's flight path.</li><li><a href="http://www.eoss.org/wbaltrak/">Balloon Track for Windows</a> is a software package that will project the flight path for your balloon. You tell the tool where you want to launch from, the ascent rate, the burst altitude, the descent rate and the wind data for your launch date and it models when and where your balloon should land. This is designed to give you a rough idea of where your balloon will go so you can avoid things such as your local airport and large bodies of water...such as the Atlantic Ocean :) If you have <a href="http://www.microsoft.com/mappoint/products/2006/default.mspx">Microsoft MapPoint</a> installed you can generate an image of the projected flight path. The green line shows the flight of the balloon during ascent and the red line is for descent. This shows us landing close to the ocean so we'll have to head west for our launch.<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6V5tRH70YqjAivnpz-XVekIxQRd3D0tPGqblF1gAW40aKw8VTdqFDoPkjruUNbswLmwl-E6AMEgmEL25CwUKq7ekjQdMBbhMhoUzRnN2X1Vl6jOeSuk7IrlMddOhdxhAuisxzUNKichc/s1600-h/projected_path_11_05.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6V5tRH70YqjAivnpz-XVekIxQRd3D0tPGqblF1gAW40aKw8VTdqFDoPkjruUNbswLmwl-E6AMEgmEL25CwUKq7ekjQdMBbhMhoUzRnN2X1Vl6jOeSuk7IrlMddOhdxhAuisxzUNKichc/s320/projected_path_11_05.jpg" alt="" id="BLOGGER_PHOTO_ID_5129450854427417298" border="0" /></a> </li></ul><br /><span style="font-weight: bold;">Payload<br /><br /></span>Our payload is pretty simple, we don't have an onboard computer so the only software application we are using is for our camera. <a href="http://chdk.wikia.com/wiki/Main_Page">CHDK</a> is open-source 3rd party software that runs on several different digital cameras. We need to use CHDK to program our Canon A610 to take pictures on some set interval for an extended period of time. The default canon firmware has some time-lapse photography ability but it is limited to 100 pictures. We would like to take as many pictures as we can on a fully charged set of batteries thus the 3rd party software.<br /><br /><span style="font-weight: bold;">Chase Vehicle<br /></span><ul><li><a href="http://www.elcom.gr/sv2agw/agwpe.htm">AGW Packet Engine</a> - This is the software that listens to "line in" on your PC for the audio coming from your receiver.

Now we're working some on the mechanical engineering parts of the project: putting together the payload and connecting it to the balloon. A week ago Sunday, we made a trip to <a href="http://www.lowes.com/lowes/lkn?action=home">Lowe</a>'s to buy some of the nuts and bolts (literally) of the project. (When we figure out exactly what pieces end up as a part of the final project, we'll list them here.) We met at Dale's to work on building the payload.<br /><br />We got a medical-grade styrofoam cooler, which came in a box like this one that Erin is modeling for us.<br /><br />Dale and Alli drilled some holes into the cooler to push through two threaded metal rods, which were cut from a single 3-foot span. Unfortunately, the threads got crushed from being held in a vise to be cut, so we ended up breaking the rods and stopped for the day.Michellehttp://www.blogger.com/profile/08981368401994513822noreply@blogger.com0tag:blogger.com,1999:blog-5480060546986548590.post-81175125519631901332007-10-16T21:48:00.000-04:002007-10-17T06:58:40.225-04:00What's Your Vector, Victor?

These guys are working on a project to photograph a large geographic area following a natural disaster (think New Orleans the day after Hurricane Katrina). The logic is that it can take several days to reposition a satellite to photograph the disaster zone so why not use a high altitude balloon with a digital camera to do the job ASAP.<br /><br />They have developed a mechanical device to twist and tilt the camera so they can photograph a wider area than if they only snapped photos with the camera pointed straight down. The pictures are then stitched together to form one larger picture like so:<br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/5955/293/1600/pano1.jpg"><img style="cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjMdeEcyf80q2fSO4n2W0JXeJlA6wBUu3pcGjyZcN7vGwlK8WmB0VnolmYgFX4AvTMe0RjZwheG1VOOcK_WH1l6Qd7t0bbNHuN85z3hyphenhyphenb7nyzxwP7DulvnOoHwYk97s4pTHihz_RNP0no4/s320/pano1.jpg" alt="" id="BLOGGER_PHOTO_ID_5115267329432964514" border="0" /></a><br /><br /><br />It seems like a good idea.

We found several other balloon blogs but none of them gave much detail on how they did everything. We're going to try to document as much as we can so that hopefully someone can use this blog as a reference for their own balloon project. That said, here is a rough overview of how we think this will work. We're learning as we go though so I'm sure this will change.<br /><br /><ul><li>Ascent - This is the easy part (we think). We buy a <a href="http://www.kaymont.com/pages/sounding-balloons.cfm">weather balloon</a>,<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgE6NuhTRVcOPOhWRkXW6ciDGoCtwgVeaqHKnhWyF1QjE_DfGxsFuqN4P7gv1Yl_hrH9kNKKx92Le4JKtKhHT0A1ydDa0BWGK281xs6j3ZyTzeRuugVieEyh622ZdjcfjMYYpmtIrFNBqY/s1600-h/hindenburg.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgE6NuhTRVcOPOhWRkXW6ciDGoCtwgVeaqHKnhWyF1QjE_DfGxsFuqN4P7gv1Yl_hrH9kNKKx92Le4JKtKhHT0A1ydDa0BWGK281xs6j3ZyTzeRuugVieEyh622ZdjcfjMYYpmtIrFNBqY/s200/hindenburg.jpg" alt="" id="BLOGGER_PHOTO_ID_5114002659132788034" border="0" /></a> put our camera and other electronics gear in some sort of styrofoam box, attach the box to a parachute and attach the parachute to the weather balloon. Then we fill our balloon with enough <a href="http://en.wikipedia.org/wiki/Helium">Helium</a> to lift the payload (camera, styrofoam box, parachute, etc) plus 1 lb to 1.5 lbs of extra lift. Dale found a chart that shows what the ascent rate should be based on how much extra lift you have. I'll get that from him and will link it here. I found one balloon site where the group was using <a href="http://en.wikipedia.org/wiki/Hydrogen">Hydrogen</a> to provide lift. Didn't the Germans give that a try a few years ago? :) I like having eyebrows so I think we'll stick to Helium.</li><li>Descent - At some point the weather balloon will burst due to the expansion of the Helium. Of the other balloon project websites that we've read the highest launch was to 117k feet. That's pretty darn high if you stop and think about it! I know I'll be very happy if we get anywhere close to that. Anyway, once the balloon pops you need a parachute to get your payload back on the ground in one piece. <a href="http://www.the-rocketman.com/chutes.html">Parachutes from model rockets</a> seem to be the popular choice. We haven't ordered one yet because we don't know how much our payload is going to weigh.</li><li>Camera - Obviously we want something digital and we need a way for the camera to take pictures without any user intervention. The easiest thing to do is buy a camera that has an <a href="http://en.wikipedia.org/wiki/Intervalometer">intervalometer</a> feature which allows you to set the camera to take a picture every X seconds. The other option is to rig some sort of mechanical device to push the shutter button every X seconds. Dale has tracked down a free camera for Project-WARPED but it doesn't support invervalometer so we will have to rig a mechanical solution. Here's a great <a href="http://www.zardec.net.au/keith/lapse2.htm">website</a> for some more information on time lapse photography.</li><li>Tracking - This is the tricky part. If you launch a balloon to 100k feet and take lots of cool pictures you need a way to recover the camera when the balloon finally lands. We will be using <a href="http://en.wikipedia.org/wiki/Automatic_Position_Reporting_System">Automatic Position Reporting System</a> (APRS) to track the balloon's location. In a nutshell, APRS is implemented by using a GPS receiver that attaches to a RF transmitter which in turn transmits the GPS coordinates via <a href="http://www.tapr.org/pr_intro.html">packet radio</a> (this is why we needed our ham radio licenses). We will pick up the RF signal from our transmitter (the Micro-Trak 300) by using a RF scanner on the ground. The headphone output from the RF scanner feeds into a laptop's microphone input which decodes the data from the scanner into a digital format containing the GPS coordinates of the balloon. Doing this last part on the laptop is something we don't have working yet. The following powerpoint presentations have more detail on APRS and how it ties into ballooning:</li><ul><li><a href="http://project-warped.googlegroups.com/web/Intro_to_APRS.ppt?gda=y96by0IAAAASv2MddyBYN3XO4VrfY9AI3AnyJuIzjcknxEHsL7Z_dWG1qiJ7UbTIup-M2XPURDSPJbHFLP2t0nwS0NhNfz1Fj6g-1kuiDGocFuQOlPjFVQ">APRS Introduction</a></li><li><a href="http://project-warped.googlegroups.com/web/APRSballoons2.ppt?gda=VzYfg0IAAAASv2MddyBYN3XO4VrfY9AI3AnyJuIzjcknxEHsL7Z_dWG1qiJ7UbTIup-M2XPURDTXYkndS-yzgPu6XUWo1ulej6g-1kuiDGocFuQOlPjFVQ">APRS and Ballooning</a><br /></li></ul></ul>dwalton76http://www.blogger.com/profile/01231435969332456287noreply@blogger.com0tag:blogger.com,1999:blog-5480060546986548590.post-2378149958923140552007-09-17T10:32:00.000-04:002007-09-24T23:53:00.659-04:003 for 3 on ham radio licenses<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_LJ6wp7ToBO3B5ObcPFRtA1zdp1aaMH7EJwz3tjef_QfFUx2cXIZveTtLuQWDwSPd06DidxhP-5UxPIVgz9wrbFzinxbzq1qB_9MZvpl3OfnxEptrSxORX-tS7Flv3D8cL6ygoXqyhoA/s1600-h/Ham.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_LJ6wp7ToBO3B5ObcPFRtA1zdp1aaMH7EJwz3tjef_QfFUx2cXIZveTtLuQWDwSPd06DidxhP-5UxPIVgz9wrbFzinxbzq1qB_9MZvpl3OfnxEptrSxORX-tS7Flv3D8cL6ygoXqyhoA/s200/Ham.jpg" alt="" id="BLOGGER_PHOTO_ID_5113984620270144802" border="0" /></a>All three of us passed our ham radio license test on Saturday morning!! I was sitting next to Alli when I heard the test administrator whisper to her "congrats, you only missed two" so I just guessed "C" for all remaining questions on my test. We only needed one of us to pass anyway and I really had to pee so I figured why not :)<br /><br />We have to wait for our names to show up in the <a href="http://www.arrl.org/fcc/fcclook.php3">FCC database</a> before we are officially licensed. That's supposed to take about two weeks so it isn't the most efficient process in the world. Once that happens we'll be able to begin testing our GPS and the little radio that transmits the GPS coordinates over radio. In the meantime we're going to start working on some sort of payload box to hold the camera, radio, etc. That's all for now...dwalton76http://www.blogger.com/profile/01231435969332456287noreply@blogger.com1tag:blogger.com,1999:blog-5480060546986548590.post-41182386755494146662007-09-07T23:52:00.000-04:002007-09-24T23:51:26.297-04:00Why "Deathstar"?<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgdo_r-3U4UX8w90S6tClkMWVfKLFawHolYuHjgMFwvRqk_HGp4oNmB0uAz-NKwDjJemfgR28lZnXFJ7VDe5pJnh0soiwJoRJCKe6Z-b3GQdlQbDU81At4sCjQA7tI1WMzTKOIINuOUyj0/s1600-h/deathstar.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgdo_r-3U4UX8w90S6tClkMWVfKLFawHolYuHjgMFwvRqk_HGp4oNmB0uAz-NKwDjJemfgR28lZnXFJ7VDe5pJnh0soiwJoRJCKe6Z-b3GQdlQbDU81At4sCjQA7tI1WMzTKOIINuOUyj0/s200/deathstar.jpg" alt="" id="BLOGGER_PHOTO_ID_5113984139233807634" border="0" /></a><br /><div>What does the <a href="http://en.wikipedia.org/wiki/Deathstar">Galactic Empire's Deathstar</a> have to do with tying a digital camera to a balloon and floating it to 100,000 feet to take some cool pictures? Well to be honest with you....absolutely nothing. Alli came up with "Wolfpack Amateur Radio Photo Experiment" but WARPE doesn't sound nearly as cool as WARPED so we started brainstorming for a word that begins with D that we could somehow relate to cameras or balloons or amateur radio or space. Alli came up with Deathstar (can you detect a theme here with Dale and Daniel's lack of creativity?) and so "Wolfpack Amateur Radio Photo Experimental Deathstar" it is. BTW did you know that Warpe "is a municipality in the district of Nienburg, in Lower Saxony, Germany"? At least that is Wikipedia's take on Warpe.<br /><div><br />I feel like I should mention that this is my very first post in a blog ever!!

The test is 35 multiple choice questions and you have to get 26 correct to pass.

So this saturday the three amigos go to <a href="http://www.arrl.org/arrlvec/examsearch.phtml">take our exams</a>. Good thing we all have some electronics background, we already learned a lot of this.

We think we'll probably have to drive west to release the balloon to make sure that it doesn't end up in the Atlantic ocean.
