Introduction I’m in the process of building a long range FPV plane (article to come eventually) and one part of the radio link that always fascinated me was the antenna tracker. This setup will utilize a highly directional antenna for the telemetry link but the problem is the plane will always be changing locations. How can we make sure the antenna is always pointed at the right location? The solution is to use the plane location data from the telemetry log and compare it with the location of our antenna.
Introduction I’m back and Happy 2023! It certainly has been a while. I’ve recently been attempting to do more low level learning and discovered a way to keep myself interested long enough to actually learn something by hacking one of my favorite games. Megaman Legends was a ps1 and n64 game that was also released in Japan on pc. Unfortunately the game is only in Japanese and fullscreen only. This is an effort to fix some of these quality of life issues in the game while also learning the basics of game hacking in general.
Introduction I run a few Minecraft servers for my Discord and utilize a plugin called Dynmap. This plugin allows players to view the world map in their browser and see where other players are at. Dynmap takes the minecraft world file and renders tiles for the web app and stores them on disk. I recently discovered that Dynmap “supports” writing its map render files to a mysql database which I thought was pretty cool.
Introduction I want to say first off that the weather station has been running for over a year and a half now with zero intervention on my part 🎉. This is not to say though that everything has been smooth sailing. I’ve actually had more issues with the API/Database side of things which is what this post is going to address. Ok, so the content of this post won’t actually address any problems (It most definitely will create several more) but I like to convince myself I am being productive.
Introduction Ohh boy its been a minute but progress is being made! This post will be a little longer than the others and also picture heavy, you’ve been warned! We last left off assembling the battery and testing. The battery has been finished and the BMS (Battery Management System) wired up and installed. Additionally most of the electronics have been mounted, ballast system fleshed out, and a fancy cover for everything printed.
Introduction Around sometime in 2019 I was doing a lot of projects with the raspberry pi and got to thinking to myself; how hard would it be to make my own from scratch? I considered myself fairly competent with electrical theory (for a hobbyist) and had some experience in pcb fabrication. So I got to researching if any others had attempted similar feats. I quickly stummbled upon George Hiulliards linux powered business card and became so inspired I decided to give it a go myself (His write up can be found here https://www.
Introduction If you read part 1 the rov has a frame, motors, and a housing for the electronics. The next issue to address is the power supply. I’ve been looking at doing a battery based on the 18650 cell for some time and finallly found a cheap supplier for 18650 cells. I grabbed a bunch of modem batteries from https://batteryhookup.com/ and got to work.
Battery Design The ESC’s (Electronic Speed Controllers) for the thrusters are rated for 11.
Introduction First post of 2021! So its been a while since the last post on the blog and I’ve started on a few new projects. One of them is something I’ve wanted to do since I was a kid and that is build a proper ROV. With the advent of the raspberry pi and easy access to code the past few years this project was something that seemed more feasible than before and I decided to dive in head first (pun intended).
Introduction ⛈️ We made it on Hackaday! https://hackaday.com/2020/07/13/solar-weather-station-listens-for-lightning/
First Post of 2020! Its been a while but I have been working on quite a few projects lately. Out of all the projects I’m working on, the one I’m most excited for is reviving my solar powered weather station. This was something I started back in 2017 but after some hardware failures (due to lightning strikes) I lost interest in continuing the project.
Introduction This all started with a discord bot I was building for friends. I was thinking of neat features to add when I found someone post a “star field” in another discord server. I thought it would be fun to have a algorithm that could generate random star fields on demand. Achieving this was fairly simple but got me thinking, is it possible to force the algorithm to generate a star field from a seed value?
