So, last night we made the totally irrational and silly (and awesome) snap decision to make a homebrew PCB for this controller. I spend quite a while laying it out, minimizing traces on the top to connections we can make with wire if we don’t see dual layer homebrew working out. I completed the first [...]
As I mentioned in my previous post, I’ve been working no this controller for the K2CC balloon launch. I’ve made some more progress this week, with final integration of all the sensors in to the same set of firmware, and the first of the weird bugs cropping up. As it’s pretty late, I’m not going [...]
One of the biggest projects my schools amateur radio club, K2CC, has taken on this semester is launching a High-Altitude Weather Balloon to capture photos and sensor data from altitudes as high as 20 miles. I have been working with a team of people to design, build and program a microcontroller powered instrument pack. Over [...]
I got my first QSL card in the mail the other day, and I just managed to open it up and take a look! Take a look for yourselves:
Backstory For the last two years or so, I’ve been working on K2CC‘s D-STAR Repeater and Gateway system. One of the main projects on the plate is making a 1.2GHz digital data network based around ICOM radios to link up local emergency services and hospitals, so that in the event of a weather emergency they [...]
Backstory Back in 2008, K2CC was planning on putting up a motorized satellite tracking tower that would point various direction antennas at a satellite and follow it through the sky for operating satellites down in the shack. As part of this plan, K2CC had a panel made with several feed-line connectors, 15 to be exact. [...]
So there’s been some progress on the D-STAR Heat Map project, Phil has refined his mapping algorithm a bit, and Shaun has attempted to use some GIS tools to generate a different kind of map. All in all, both attempts came out well, but we’ll probably be going with Shaun’s technique. However, the processing that [...]
Well, since I was writing the projects page I thought I’d write a quick post detailing the latest developments on my projects. This pertains to Mini-DMX, The DSTAR Heat-map and my mixer mostly. Mini-DMX I’ve got the rest of the layout drawn up on my little perfboard planning sheet. After my break this weekend when [...]
