Set up Octoprint on my 3D printer using my Hack Club purchased Raspberry Pi Zero 2 W!! This was a great project, and had a little bit of everything! Summary:
• Designed and printed T-Slot extrusion attached holders for the raspberry pi and my USB camera for print monitoring (majority of the work)
• Set up some electronics to use a relay to turn the printer on and off via the raspi
• Set up octoprint itself, with various helpful plugins
• Integrated Octoeverywhere to access it from outside my home, and partnered that with the Octopod app on my phone
Overall, I'm super proud of how it turned out! You can check out my STL files and a couple pictures at the github: github.com/LandonBayer/PrinterFiles
Here's another for y'all: wokwi.com/projects/404030077368880129
GitHub: github.com/LandonBayer/FilamentScaleESP
This is a ESP32 based 3D printer filament scale to determine (roughly) how much filament is left on the spool. It automatically calculates the weight left in grams, percentage of the spool used, and displays on the LED bar graph a visual of how much remains. The 4 digit display is a simple scale for any other objects being measured.
Finished my bin project! Check it out here: wokwi.com/projects/403968266615030785 or here: github.com/LandonBayer/BinRoomSensor/commit/5cc5ff84bb750486837644a467b4645277d64b60
This is a Raspberry Pi Pico based Temperature and Humidity display that uses a combination of a motion sensor, photo resistor and IR remote/receiver to add some helpful "automations". The motion sensor turns on the display when it detects movement, but the photo resistor makes sure it stays off during the night unless you use the IR remote to turn it on in the dark. This way, it won't disrupt your sleep or work at night with accidental triggers of the motion sensor!
I'd like to showcase two little PCB's I made the last couple days. First is my redesigned 7-40V to 5V regulator, which I had to remake after following a tutorial so that JLC could assemble it. That has since gotten the Onboard grant and is on the way! I also made a USB A or C input to 3 USB A and 1 USB C output hub, very roughly following Hack Club's USB Hub tutorial. I had to change out almost every header component multiple times to make it work, so I really hope it does. That project is pending approval by Onboard.

Hub: github.com/hackclub/OnBoard/pull/830
I made a 24V to 5V low emi PCB using Kicad! To be clear, I followed a tutorial on it, but I have never used the software before and had some fun with it overall. Unfortunately, I can't order it with assembly as the components aren't available with JLCPCB. Now I'm redesigning it myself to use components they can assemble. Check it out here: github.com/LandonBayer/OldBuckConverter.git
Finally finished the cadvent!!! The parts got much harder as I went, so I started doing about 4 parts for hour and ended with barely 2 😭 but we got it done

I didn't finish the last part because the drawing was really bad and unrealistic in competition. There was no reason to invest tons of time to figure it out with a part like that. Otherwise, all of them were done exactly right as far as I can tell, and my document can be used as a sort of solution for anyone else working on it!
I've been grinding the 2023-24 FRC Cadvent challenges a bit, and I thought I'd do a scrapbook post since I'm about halfway (11/25 done). These have been an awesome challenge to test my abilities to interpret drawings and generally understand how to use cad most effectively. Check out the Github post (with the onshape link on it) here: github.com/LandonBayer/Cadvent-Uploads.git
I made a goofy little 3D printed hammer with the core of a mini CIM motor inside (don’t worry, it was broken). It’s a goofy project, but I actually put kinda a lot of time and effort into it so I home y’all enjoy!! Unfortunately, I spent a bit working on a little build and test video but it won't upload 😞 Once I get it up somehow I'll attach it here for reviewers. For now, here's the github: github.com/LandonBayer/Mini-CIM-Core-3D-Printed-Hammer.git
I soldered together a little circuit board and controller on a PCB that buzzes and flashes when it detects a high or low temperature (set when powered on). It was a fun little project to practice and used up all of my solder 🤣
Here in the pictures you can see my horrid set up, but it got the job done. In the video I set the high close to room temp and breathe on the probe to increase the temp and demonstrate the capabilities.
In the long term, I’m thinking of a way to add this to the coolant system on our cnc router for my FRC team to alert us when it’s getting to warm and should be switched
I sometimes hurt my nails a bit getting the starting lines of 3D prints off or the raft (if that's the right word), and I've seen some scrapers online, so I decided to make my own! I generally made up the shape similarly to other ones, but added some nice fillets and imprinted the 3D model of my robotics team's logo into it for a bit of decoration. I also created an easy-to-print mounting mechanism that slides into the aluminum extrusion at the top of my Ender 3 V2 Neo. In my slicer, I gave the front end of the scraper a 100% infill to ensure it stays strong for many uses in the future.
