2018

Hey All,

I almost didn’t blog for the whole year. To be truthful, it’s been hard to write this past year. Lots of amazing wonderful things have happened to me in 2018, but I’m exhausted. And this blog was easy to overlook. I want to write again, but at my own pace. I’m going to try to start again.

That said…. BEING A FATHER IS AWESOME! I have an amazing little mini me who is 20 months old and is just so much fun. He has made me grow in ways I never even knew imaginable.

Maker Faire Orlando 2018

My friend Jacob and I worked on an awesome project for Maker Faire Orlando this year, and I am so proud to say we won Maker of Merit! It is a deep honor to me to win that award. And of course it’s Raspberry Pi related 😀

We made a 4096 LED pixel framebuffer display powered by the Raspberry Pi!

LED Display playing a clone of Snake
Prototype at the Orlando Science Center

How it works?

We are using P10 LED panels as the basis for the screen. P10 means a 10mm dot pitch, so 10mm between each LED. They range from 3 – 10mm. The panels also usually come in a size of 16 x 32, but luckily they are daisy chainable!

The Raspberry Pi can even handle upto 32 of them in 3 chains! For our purposes we only used 8 16×32 panels in one chain.

8 P10 Panels, daisychained to an Adafruit LED matrix bonnet, connected to a Raspberry Pi 3b+, with power distributed via a CFOL Distro 8 board.

The above picture may look complicated, but it’s not that bad.

8 P10 panels are daisy chained together using a standard HUB75 cable (it’s like an smaller IDE cable).

The panels are mounted together with the orange and red 3D printed brackets.

The first panel is connected to a Raspberry Pi 3B+ via an Adafruit LED matrix bonnet.

The power for the panels and the Pi comes from a 10amp DC supply, which plugs into the bonnet. The bonnet powers the Pi, and has two screw terminals for the voltage output. The +/- screw terminals connect to a CFOL Distro 8 PCB (in the center of the board) which takes the input and breaks it out to 8 screw terminals. We only need 4 since each cable powers two panels, but it gives us room to expand.

After that we use https://github.com/adafruit/rpi-fb-matrix to copy whats on the HDMI framebuffer out onto the LED matrix!

and Voila! You now have a giant low resolution display!

Many thanks to Adafruit for making such a great beginner tutorial that we could jump from, and building a great bonnet for the Pi!

Happy Making and a Happy New Year! Here’s to a wonderful 2019 everyone!

End of 2016

Hey All,

It’s the last day of 2016.  What. a. year.

  • Finding out I’m going to be a Dad in 2017.  We just found out it’s going to be a BOY!!!! I’m so excited, and terrified, and excited.
  • K and I just got back from New York City.  We wanted to do one last big adventure before our next big adventure is born 🙂
  • We’ve been working on the PiPlay Advance handheld.  We think he have it down now.
  • Maker Faire Orlando was amazing!
  • I ran for Florida House of Representatives, and while I didn’t win, I received 31% of the vote!!!
  • I was able to hire a very talented student in our department as a full timer after he graduated!
  • I spoke at InstructureCon in Colorado, did a CanvasLive webinar for a bunch of schools, and spoke at the Online Learning Consortium conference here in Orlando.

I haven’t updated as much, and every Friday I look at the clock and miss the post.  So I’m hoping to do better at that again.

Thanks for reading!

Have a wonderful 2017!

Friday Post: 2015!!!!

Hey All,

Happy New Year!!! 2014 was an amazing year for me:

  • Got contracted to write a second book (almost done)
  • Ran a successful Kickstarter
  • Had YTD 64,000 downloads of PiPlay
  • Spoke at PyCon, Computers in Libraries, and EDUCAUSE conferences
  • Participated in Orlando Maker Faire
  • Was able to hire the very talented Elizabeth Williams to be part of my team at work
  • Developed software that is helping 60,000 students
  • Added a very cute and very annoying kitten to our family
  • Learned a few new technologies that I had been putting off
  • Watched my wife get a great new job
  • Watching my friends start families
  • Made some new friends

Not to say everything has been great, but the good has totally outweighed the bad.  I have to thank all of my readers as well.  I couldn’t have done without you all.  Thank you!

Amiibos

So I’ve been hit by the Amiibo bug.  I started cutting out these stands for my collection.

PiPlay

The next version of PiPlay is really coming along.

You can see our game listing screen now shows a lot more info.  We are also moving a lot of our configs into SQLite DB files for faster retrieval.  This is going to be an awesome release!

Happy 2015 everyone!
