Friday Post: Even more 3D printing…

Hey All,

This has felt like one of the longest weeks of my life.  Had a couple meetings about Maker Faire Orlando, pushed out some software that 60,000 students will be using in a month. It’s super stressful.  Luckily it’s Friday and I can end up sleeping until Sunday :D

I was hoping to have some cool stuff to show this week about the 3D printing software, but of course at the last minute stuff wasn’t working.

My 3D printer is a Micro3D 3D printer.  It’s a small $300 3D printer that is only now just getting people to hack on it.  With 3D Printing, you usually have two steps from model to plastic.

The first step is to run your model (an .STL file) through a slicer.  There are many slicers out there, Cura, Simple3D, Slic3r, etc.  These literally slice your model into layers which are written out as Gcode.

Gcode is an industry standard for 3D Printing and CNC milling that can control extruders, X Y and Z axis motors, temperature controls, etc.  Everything your print will do is going to be from a line of gcode commands.

The printing portion is actually a program that reads the gcode and sends it to the printer to act out.

OctoPi

There is a really cool open source suite of tools called OctoPrint, that combines a gcode processor and a beautiful web frontend to manage your 3D Printer.  A Raspberry Pi distribution was made call OctoPi which allows you to control most 3D printers from your Pi!

Because the Micro3D is so new, support is just starting to come out for it and the gcode processors are a little iffy at the moment.  I was able to get OctoPi to talk to my printer and manually move the axis, but it could not process the gcode properly.  Bummer :(

I am sure this will be fixed in the coming weeks though.  I am really happy with this printer.

Be on the lookout for a new PiPlay image.  It’s been too long!

Friday Post: Make Magazine!

Hey All,

Happy Friday!

This week just flew by, but projects are going really well, and I am hoping to have a cool announcement in the next week or so.  In the meantime…

PiPlay was featured in Make Magazine!!!!!!!

I’m seriously fanboying over here.  To have my project featured in Make is like having a researcher’s paper featured in Science or Nature magazine.  I’m just blown away.

The article is about making a home arcade system and controlling the games with an Arduino Esplora.

Have a good weekend all!

Friday Post: Working Working Working

Hey All,

I feel like I have a ton on my plate and nothing to show….yet.  Working on PiPlay, our new remote controller system, an arcade game for Orlando IX, and an arcade machine for Maker Faire Orlando.  It’s going to be a rough couple of months :)

This weekend is Community Effort Orlando, an annual fighting game tournament held near the attractions.  I’ve never been to CEO, but I’m really looking forward to it.  Street Fighter V is going to be playable, as well as Tekken 7.  I’m also going to be able to play a lot of arcade games :D

Have a good weekend!

Friday Post: Happy 90th Birthday Grandma!

Hey All,

First off, Happy 90th Birthday to my Grandma B!!  Love ya!

It’s been a hectic few weeks.  The migration has gone pretty well.  I have some more stuff to move over, but I’m happy with it.  The server is so powerful.

Mark and I are going to be bringing up a new service for gamebox art soon to help with PiPlay.  I have also been hard at work on some electronics stuff, and Mark has been doing some cool coding.

I’m really looking forward to the next month.  I have been pulled in a lot of directions, took a few breaks, but I think I’m finding the right thing to move forward with.

I can’t wait for the next part of this ride.

Have a good weekend everyone!

Friday Post: PyCon 2015!

Hey All,

PyCon 2015 is over.  It was an amazing time in Montreal.  My coworker and I presented ProctorHub, the homegrown proctoring solution that we created for our university.

We met a lot of fellow educators, tons of fellow pythonistas, and learned a ton!

A PiPlay kit was also auctioned off during the PyLadies auction, where it brought in $200!

All of the talks are up on YouTube:

I’ve also picked up two of these nrf24l01+ Transceivers.

I have a neat project I’m working on involving a Raspberry Pi and an Arduino.  Hopefully I’ll have the prototype to show next week :D

Have a good weekend!

Friday Post: PyCon 2015, also Make!

Hey All,

So next week I will be in Montreal for the annual Python Software Foundation conference: PyCon.  My coworker and I will be presenting a project we developed at UCF that uses Django, AWS, and a bunch of other tools that allow us to help 60,000 students learn in a better environment.

Next Friday’s post will probably be late, depending on what the internet connection is like up there.

Also, Make featured PiPlay in their latest video!

Have a good weekend everyone!

Friday Post: PiPlay 0.8 Beta 9 Released!

Happy Friday Everyone!

 

I am proud to present the very latest version of PiPlay!  PiPlay 0.8 Beta 9!  I feel like this is the best release yet!

While this was mostly a bug fix and compatibility update, we do have one awesome new features implemented.  When you upload, drag and drop, ftp, or somehow copy a game file to the roms folder, our file watcher will pick that up, and automatically update the PiPlay Menu.  No more running the Rom Scraper, or getting popups about unscraped files.

Update now via the PiPlay Menu, or download the latest image!

 Changelog
  • Numerous bug fixes!
  • Updated to latest Raspbian
  • SQLite Backend
  • Webserver now a background process via supervisor
  • File Watcher automatically scans for game files and updates the PiPLAY menu
  • Raspberry Pi 2 comparability
  • Controller config updated
  • Moved more repos to GitHub
  • Master games list updated
  • Toggle menu item visibility (in beta mode still)

Have a good weekend everyone!

Late Friday Post: Pi Day!

Hey All!

Happy Pi Day!!!  Sorry about the late posting.  My internet has been acting up for the past two days.  Yay.

The past few days have been the Orlando FIRST Regional Robotics Competition hosted at UCF.  I am a FIRST Alumni from 2002, a member of Team 108 SigmaC@Ts.  It was so awesome to see the competition again after all these years.

PiPlay is coming along.  Fixed the bugs with the joysticks.  Working on improving more things.

Thanks!

Friday Post: PiPlay 8 Beta 8!

It’s now available on SourceForge!

Hey All,

PiPlay 8 Beta 8 is here!  Mark has put a huge amount of time into the new frontend code.   We have moved form YAML files to a SQLite database.  Many items have been sped up.  The web frontend now has a database administration section.

This is a huge update.  Probably the best I think we put out… but because of the Pi2, we have had to do a lot of extra testing, and may have missed some stuff.  Please please please let us know if something isn’t working, or if something slipped through the cracks.  I want this to be the best release ever!

This new image will work on the Pi2 and B, B+, A, and A+.  I have spent the past week pulling out hair trying to get everything to work.  I have had to remove Stella, the Atari 2600 emulator for the moment.  When I can get it working properly on the new kernel, I will add it back in.

The image is currently being uploaded to SourceForge, so in a few hours it should be available.

Thanks for your patience, and thanks to all the testers.  If you find any bugs (I’m sure there are some) let us know in the PiPlay forums.

Friday Post: Termboy

Hey All,

Happy Friday!

So I have had my Pi2 for a week, and I gotta say, it’s a great piece of kit.  PiPlay is coming along nicely.  Having some hiccups on the Pi2 that I need to fix before I do a full release.

TermBoy

With that being said, I saw on Hacker News today a port of a gameboy emulator to the Go language, that also only utilizes the console.  It’s called Termboy, and while it doesn’t run that fast on the Raspberry Pi, it’s still a neat little tech demo.

We first download the proper console font and install it:

wget http://kbd-project.org/download/kbd-2.0.2.tar.xz
tar xf kbd-2.0.2.tar.xz
sudo cp kbd-2.0.2/data/consolefonts/default8x16.psfu /usr/share/consolefonts/

Now we download the latest GoLang version (The apt-get version of Go is 2 years old)
[code]
wget https://storage.googleapis.com/golang/go1.4.1.src.tar.gz
tar xf go1.4.1.src.tar.gz

Set the path for where we want our Go packages to be downloaded

mkdir godownload
export GOPATH=/home/pi/go/godownload/

Build Go

cd go/src/
./make.bash

One that has completed, it’s time to download Termboy and build it.

cd ../bin/
./go get github.com/dobyrch/termboy-go

Now goto the bin folder where our newly built termboy executable resides, and run it like so:

cd ../godownload/bin/
./termboy-go /path/to/game.rom

More PiPlay news soon.  Promise!
