Making Making Making

Posted on by

I’ll be honest, I really keep thinking if I blog what I’m doing now then that will be it, and I won’t have any content for next week. Hah!

Every week just reminds me how many things I end up putting myself into so yeah, I just need to stop worrying about having content and just keep making content.

I’ve been trying to do YouTube videos and blah, it sucks. It’s super hard to create content like that for me. I’m getting better at it, but it just ain’t clicking lol.

What I did these past two weeks?

Well I did setup the Ikea Lack Rack!

This setup is a beast and is taking up so much room. I have no use for it anymore, but it felt good “completing” a task I had on my todo list for years.

New GBA Flash Carts!

So many years ago I tried to do some DMG and GBA homebrew development. I didn’t get far but I had always wanted a flash cart and to be able to run my own code on a Gameboy!

Well, in 2021 there are now homebrew flashing devices, because all of the pirated / reproduction games out there are actually just really cheap 16MB reflashable cartridges!

A secret santa sent me some games a while ago and a few of them ended up being pirated (The E and Nintendo logo are too thin!) carts. I picked up a GBXCart reader/writer and now I can flash my own games to the carts!

Raspberry Pi Press

I’ve had these books on my sights for a while now, but I just never bit the bullet. And to be honest, it’s been hard to be motivated to read lately. BUT I’m going to fix that. I’m going to read. My goal is to finish both of these books by the end of July.

Next week I’ll have some more new videos ready. Did something cool with my coworker on my CNC machine to help his D&D campaign, and one of the Kickstarters I backed delivered their console, so I hope to have an unboxing done by then.

Have a good week all!

Projects!

Posted on by

Hey All,

Last post I talked about completing projects…and I’ve got an update on my First Order Stormtrooper helmet!

99% done! I just need to do a little more touchups, paint the vent silver, and add the lenses!

Here’s what it looked like as I was touching it up:

Hopefully in another week or so I can finish it up!

Chip Coasters

Last week on Twitter I saw Eben Ubton and @jasoncoon_ talking about etching CPUs into slate coasters, so I had to try it myself.

I made a video of the creation and etching process. Hope you enjoy!

See y’all next week 🙂

2021 Obtainable Goals

Posted on by

Hey All,

So, I’ve been reflecting on the past year and the past month, the things I’ve made and the things I haven’t. I’ve come to the conclusion that for this year I only want to put my energy into projects I know how to complete or have the capability to do.

I know that sounds wishy washy but I have a TON of unfinished projects on my backburners, and I needed to tell myself I will NEVER finish those. So it’s time to move on, clear the clutter, and finish the projects I can finish, and start the projects I can complete 😀

On Deck To Complete

My First Order Stormtrooper helmet. I’ve been working on this thing since 2017. I love the look of the helmet, and I’ve printed about 4 different complete ones but they always never felt good enough. The finish wasn’t good. I didn’t know how to sand well enough, etc. Excuses.

Primed, badly sanded, sitting on my shelf…

I’ve had this dude sitting on my shelf for 6 months. I started this when the pandemic started, and then got discouraged after I saw the imperfections and mess ups. So this weekend I said screw it. I’m going to finish it, imperfections or not. I will use what I gain from this one to make the next helmet even better!

Here’s how the weekend went:

First coat of black spray paint!
Second coat!
Lots of trial and error with masking.
First coat of white over the masked elements.

I think I got pretty far! Painted black as a first coat, masked, then painted over white. I’m going to do the second coat tomorrow then expose the masked area.

My masking attempt is not great, but I can only just touch it up. Perfect is the enemy of good here. I also saw an awesome technique on how to make the eyes: Document folders! They are a great source of dark see through plastic. You cut it out and tape it to the inside of the helmet and BAM! Instant visor!

Stepmania Raspberry Pi Dance Pad.

This is something I have no idea how to finish yet, BUT I have an idea on where to start. Using FSRs works. The prototype works. But I want to build something nice. I think I am going to try to make some custom FSR PCBs and install them into 2020/1515 aluminum extrusion.

IKEA Lack Table Server Rack

I have an old xServe Mac 1U server, and a bunch of home lab equipment sitting in my garage. I’ve wanted to revamp my home network and move everything outside a shelf in my closet and “properly” set it all up.

I’m thinking of using the IKEA Lack Rack project as my base.

While this is definitely low priority for me, it would make me feel better having it all in some semblance of an organized mess.

2021 Maker Faire

I’m currently going through some thoughts and idea for what will hopefully be Maker Faire Orlando 2021. 2020 got shelved due to COVID, but I’m hopeful 2021 will be on.

I’m looking forward to tackling my projects this year, and hey, actually completing things.

Have a good week all!

IPS LCD Upgrade for a GBA SP

Posted on by

Hey All,

Well this has been a week! Here’s to hoping President Biden can usher in some new progressive policies and finally have a government that takes the Coronavirus Pandemic seriously. All I want is my vaccination ASAP!

Tryign to take my mind off everythign I’ve been throwing myself into lots of projects that I KNOW I can complete. One of those was to upgrade one of my older GBA SP AGS-001 consoles with an awesome IPS LCD screen.

The difference between the original frontlit screen versus the new one is night and day!

This is a time-lapse of me refurbishing and upgrading a beat up original Japanese imported GameBoy Advance that used a front-lit screen.

I take it apart, clean it all out, then replace the screen with a back-lit IPS LCD and new casing for the screen.

The actual hardware swap took less than an hour including soldering the LCD brightness control wire and then me messing up and forgetting to put in the hinge locking screw the first time around.

The screen (and new cases) are easily found on eBay – https://www.ebay.com/itm/V2-IPS-GBA-SP-Backlight-Backlit-LCD-For-Game-Boy-Advance-SP-Pre-cut-Shell-Case/184107831403 – That’s the one I used!

I also found some awesome shiny “silk” green PLA filament and printed this giant Bulbasaur!

It came out so great!

Finally, the Raspberry Pi Foundation released a new board! The Rasberry Pi Pico! Their first microcontroller!

I haven’t had much need for advanced microcontrollers like these, a regular Arduino is plenty for the little hobby projects I work on, but for $5, I’m definitely going to see if I can swap these in at some point.

Have a great week all!

Happy New Year! Hi 2021! Go Away 2020…

Posted on by

Hey all.

Happy New Year!

This year I resolve to blog once a week again. Every Friday I will post what I’m working on. I’ve become creative again (I think…) and I want to put out to the world what I’m working on.

Raspberry Pi StepMania Dance Pad

Right now I’m working on a CNC’d StepMania dance pad for the Raspberry Pi. I can’t wait to get it complete but so far we have the FSR’s working with the Arduino connected to the Pi.

LEGO

I’ve been building a few LEGO sets with my toddler these past few months. Mainly I build them and he does QA I should say 🙂 It’s so much fun watching him get better and better at putting stuff together. I love it!

3D Printing

Last print of 2020 was of course a Bulbasaur. My favorite starter Pokémon!

Image may contain: indoor

I backed Naomi Wu’s 3D PrintMill “infinite Z” printer on Kickstarter which should hopefully arrive in a few months. I know how many 3D printers have failed on Kickstarter before, but this is a collaboration between Naomi and Creality, and they already have the printer built, this is more of a way to how many they need to make for their factory. And I get that. It’s a great use of Kickstarter. I’m excited to buy vast amounts of filament for this thing!

Conveyor Belt 3D Printers : Creality CR-30 3DPrintMill

That’s it from me for this week. Here’s to an amazing 2021!

See ya next Friday!

StepMania on the Raspberry Pi 4!

Posted on by

For anyone that knows me, Dance Dance Revolution and StepMania were a large part of my life years ago. It’s how I lost a ton of weight.

6 years ago was my first attempt to get StepMania running on a Raspberry Pi…and it was a horrible experience.

Today I’m proud to say that StepMania runs GREAT on the Raspberry Pi 4!

I’ve hosted the shell script / step by step instructions on how to compile and run StepMania on your own Pi4 as a GitHub Gist:

Just run these commands in a terminal on the Desktop GUI version of Raspberry Pi OS and you will be up and playing StepMania in about an hour.

Enjoy!

Things I did in 2020

Posted on by

So, like my last post stated, I did some things while stuck at home.

My absolute favorite project was this:

I followed this guide (https://github.com/geaz/simplyRetro-D8) and built this awesome 3D printable desktop arcade cabinet. It of course uses a Raspberry Pi running RetroPi and uses an awesome readily available 4 x 3 LCD screen!

And of course my little guy helping me build and test it 😀

I got a small CNC machine in January and hadn’t had time to use it until recently but I have been having fun making some videos of it in action.

That’s a 3040T CNC Machine. You can find a lot of them on eBay and various other importing sites. More fun hobbies that involve turning one thing into another thing 🙂

On that note, I repurposed my 4k LED display for a lot of statements this year!

My house got egged for one of those statements. Worth it.

I edited and 3D Printed a mini Dreamcast case for the Raspberry Pi! Did you know you can play Dreamcast games at 60FPS on the Pi4 now? No? WELL YOU CAN! Using Redream it’s totally possible! You can download the case files here https://thingiverse.com/thing:4539273.

And we got a new kitten!

Say hi to Dash. Our Manx kitty. He’s kinda awesome.

If you’ve gotten to this part of the post, all I can say is thank you! It’s been a year. Please stay safe out there. Wear a mask. Keep on making. I’ve missed y’all!

2018

Posted on by

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!

Friday Post: PiPlay Portable funded :D

Posted on by

Hey All,

Thank you, to my backers, and supporters, for helping to fund the PiPlay Portable. I’m so excited to get to make this.

We just got the latest prototype boards in, as well as our stickers from StickerMule.  We were also able to get some polybags for real cheap (they are in beta, so why not!)

Also MegaCon is this weekend!  I finished making my Nintendo Switch Arcade Machine and made it an Ultra SF2 Machine.

Have a great weekend all!

PiPlay Portable – Last Day

Posted on by

Hey All,

This has been an exciting week.  The PiPlay Portable is fully funded, and we have less than 12 hours to go on the Kickstarter!


Sam has been growing so fast!  I love being a Dad.  It’s an experience I am so happy I get to have, and of course I have 3D scanned him and got him 3D printed…

 

I also won the Community Leadership award from IMS Global at the LILI conference.  I had no idea I was even nominated!!  I am really humbled by this.  Thank you IMS!
