Bringing Practical Pedagogy and Sustainable Enterprise to Makerspaces

This article by Will Holman ( @objectguerilla ) really resonated with me. Makerspaces really need all these things to help would-be makers develop their skills and create sustainable enterprises.

From https://placesjournal.org/article/makerspace-towards-a-new-civic-infrastructure/ :

The movement will need to embrace spaces that feature both traditional and advanced fabrication tools at affordable prices; that provide not only for tooling but also for assembly; that offer wrap-around business services for maker enterprises; that develop maker education into a rigorous pedagogy; and that help build a sustainable market for maker-made goods and services.

Got GPSD Working on the Raspberry Pi

Took just a little digging to find the correct commands to get my Arduino + Adafruit GPS based “clock” to talk to gpsd on the Raspberry Pi (the Arduino is powered and connected to a USB port on the Raspberry Pi.)  First, I did

sudo apt-get install gpsd
sudo apt-get install gpsd-clients
sudo dpkg-reconfigure gpsd

(using /dev/ttyACM0) when prompted and then

cgps

for the display below

XW-2E

Using CubicSDR, a rtl-sdr dongle and the tracking software I’m developing (and a nice Arrow II dual band yagi), I picked up the CW beacon for the recently launched XW-2E cubesat this morning (see the portion of the waterfall display circled in red

Hopefully Less Crashy Now

New firmware (thanks steveis), recalibrated, fixed some incorrect settings in the transmitter too.  Setup autolevel correctly this time.  Still waiting for replacement arm.  Soon.

First WX Image from NOAA-18

I received my first WX image from NOAA-18 as it passed overhead just a few moments ago.  I was alerted to the pass by the Raspberry Pi based ground station-in-a-box I’ve been working on (far left in the picture) and used the WXtoImg software (center) to decode the signal from my radio, piped through the sound card box I like to use.

This was with a simple 2m J Pole antenna, but I plan to build an eggbeater or maybe a helical antenna soon.  I need to build a pre-amp too I think.

Here’s a video of what it all sounded like

Here’s my final image:
