Adding dependent jars to your OpenShift Maven repo – take 2

Looking at my last post when I last did this, it’s been a year since I last deployed something to OpenShift with my own custom dependent jars 🙂 And looks like some of the paths might have changed since last time, but the approach is still the same.

What worked for me this time:

mvn install:install-file -DgeneratePom=true 
  -Dfile=../../jar-file-name-inc-version-number.jar 
  -DgroupId=your-group-id -DartifactId=artifact-name 
  -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar

Looks like the relative path to where the jar gets copied to in your remote account changed slightly since last time.

The odd thing is I still ran into issues with my prebuild script file losing it’s executable flag, and it never seems to run as part of my build, but I can run it manually my ssh’ing into my account and just running it by hand.

Wiring an Adafruit i2c LCD Pi Plate to an Arduino

I have an Adafruit i2c 2 line LCD Pi Plate that I’ve used for projects with my Raspberry Pi. It has a block of header pins that slot down onto the GPIO pins on the Pi. It seems that it’s pretty similar to other LCDs for the Arduino, so with some reading around and experimenting, it does wire up and work perfectly with the Arduino too. This post gave the me starting point for what pins wired to where.

In summary, this is how I wired it up – the Raspberry Pi pin references are the pin names that the Pi Plate would normally connect to, and which Arduino pins I connected them to:

Pi Plate Pin -> Arduino Pin

Pin2 -> 5v

Pin6/grnd -> grnd

Pin3 -> A4/SDA

Pin5 -> A5/SCL

The Adafruit LCD Arduino library works with the LCD Pi Plate without any other changes.

Success! Packet Radio via the International Space Station

I think this was my third or fourth attempt, but I just successfully bounced a packet off of the ISS as it passed over this evening – if I understand this right, the red highlighted message is my message as I received it coming back from RS0SS (the callsign for the packet digipeater on the ISS):

Amateur Radio Packet via the International Space Station (update 2)

On yesterday’s pass I realized too late that the AGWTerminal software doesn’t send unproto packets needed to send packets via the ISS. I’ve now downloaded UISS, got it sent up and checked into the Sacramento Valley Sunday evening packet net, so looks like everything is good to go.

On this evening’s pass, I started sending my cq unproto packets, but looks like I wasn’t heard. I’m wondering after reading around that my ‘via’ value should be ARISS and not RS0ISS that I was using. Apparently your via should be ARISS, but the packets recevied from the digipeater on the ISS will come from RS0ISS. So, will give it another try on the next pass at a good time.

Here’s the packets I received this evening:
