Raspberry Pi Kubernetes Cluster

Raspberry Pi Kubernetes Cluster
I figured now the perfect time for me to explore the lightweight Kubernetes project k3s. The documentation was really solid, plus I found Alex Ortner’s Medium blog post very helpful. I dusted of a Raspberry Pi 4, and three Raspberry Pi 3’s for this setup. I’m still in the mists of my kubernetes journey, but I wanted to share some of the early primitives, and some of the notes I’ve written for myself.

DIY Friendly Laser Cutter

DIY Friendly Laser Cutter
Its' been a little over 3 months since I’ve got my hands on the Creality Laser Falcon 10W, and have to say I’m thoroughly impressed. By this point I’ve been 3D printing for just over 5 years, and my second machine is still hands down my favorite 3D printer, I recommend it to anyone that ask about the hobby. The Creality’s Ender 3 Pro, and its open platform has brought me and my family loads of joy, and for that reason I jumped on the Laser Falcon as soon as it was announced.

Deciphering Nostr and it's private keys

I’ve heard of https://nostr.com for about a year, but not until recently have I experimenting with it. This post consists of my rough notes as I progressed to sending a nostr message. If you are interested in a bare minimum way to post events to nostr, read on. Generate a new private key $ openssl ecparam -name secp256k1 -genkey -out ec-priv.pem The output here as the file extension notes is PEM:

Raspberry Pi Pico Wireless & CircuitPython

Was lucky enough to get my hands on a couple Raspberry Pi Pico W recently, and just finished up initial exploration. I started with a by flashing the CircuitPython .UT2 to the pico, like always Adafruit has a phenomenal write up on just that. Next I added copied in modules from the 8.x bundle, simply toss the following into your pico’s /lib/ directory: $ ls -1 /Volumes/CIRCUITPY boot_out.txt code.py lib $ ls -1 /Volumes/CIRCUITPY/lib/ adafruit_httpserver.

Raspberry Pi Pico and 433MHz Data Radio

Raspberry Pi Pico and 433MHz Data Radio
Well its been a minute since I’ve toyed around with electronics, but a $4 Raspberry Pi Pico board arriving in the mail changed that. This board packs a boat load of utility for $4, just check out the data sheet and check out all them I2C and SPI pins! I dusted off the last components I tinkered with, along with a handful of wires. After a couple days of tinkering, I ended up with a 433MHz radio packet receiver.

Diablo RPG Style Inventory System in Unity

This weekend felt like a good time to tackle something new. After successfully prototyping a 3D Disc Golf Game , and then a Game of Life-Simulation , I wanted to explore more of the user interface side. I decided to build an Inventory management system, also decided it best to create a new project, this way I can build the Inventory as a re-usable module for more than one project.

A Game of Life in Unity

Took a little break from my Disc Golf Game to do a bit of AI programming in Unity . What I ended up with was a simple Game of Life with rabbits trying to survive. Each rabbit has a growing hunger and thirst which if not addressed will result in death. The population is also broken into male and female rabbits which can reproduce. Check out a couple minutes of the simulation running at realtime speed:

3D Disc Golf Game in Unity Part 2

Put a little bit more effort into my Unity Disc Golf game. I’ve now got ambient sounds and footstep, plus throwing is much easier with only a single click input.

3D Disc Golf Game in Unity

Still working with Unity and Blender, now I’m use some of the knowledge I’ve gained to construct a physics based disc golf game. At the moment I have 3 settings that effect the disc in flight ( fade , lift and power ), these settings can be seen at the lower corner of the screen, and can be changed using keyboard inputs. My thought is to use these as thresholds on different disc, then implement some sort of click game on each throw.
