My 3d printer broke :(
Okay so Im basically done with the designing part and now I’m actually doing the hardware, problem is my 3d printer decided to stop working or something. During a print, it just stopped extruding filament. I took apart the nozzle assembly and got the jammed filament out of the nozzle and put it back on print. Turns out the nozzle wasn’t secured enough and scratched the print bed + attacked me by ejecting a 3d print straight off the bed and into my face. I’ll try to troubleshoot this asap, but for now I’m going to do the software of my robotic arm. I’m planning on making a python app where u can use sliders to move the robots joints, and also an inverse kinematics part where the app gives you a cartesian coordinate and you have to solve and input the correct servo positions to move it to that coordinate.

FINAL FINAL devlog

Okay so I basically added all the macros to the hackpad, and made the oled screen and rotary encoder code. However, the rotary encoder doesn’t work irl because me being a genius accidentally soldered over the pads that the encoder was connected to and now one of the pin headers of the MCU isn’t soldered onto the seeduino bc of that. But with that aside, I got the macropad to work and its very functional.

ITS ASSEMBLED!

Soldered all of the keys, oled screen, and rotary encoder! Just waiting for the case to print and Im ready to ship. W project and a great intro to PCB design. Im lowkey a noob at soldering so I might’ve added too little or too much solder on each joint but the keyboard still works so lucky me ig? Im gonna ship once my case finishes printing so stay tuned

ARM #3

Redesigned the waist of the arm, started working on the gripper. This took way too long and I think its mostly because of me not knowing how to use onshape correctly (hey you learn along the way tho). Im going to work to get the gripper fully assembled and ready so I can put it on my arm as the end effector. After that, I can assemble it in CAD and start working on getting my parts ready IRL. I think designing it was easy, it was just very tedious. Software will definetaly be the hardest part of this project. Im aiming to make an App where you can control each servo’s motion using sliders. Additionally, you can give it a coordinate in a 3D plane and it’ll point to that exact spot. I plan to use processing to make that app.

ARM #2

Ok i have most of the joints designed but I’m lowkey worried about the bottom one since its kinda cantilevered but Imma redesign it if it causes a problem in the future. I have the servos all mounted to each joint and the next step is to create the gripper, which I will be doing next devlog. Its coming together all good but the real question is if it can hold up in real life.

ARM #01

Im making my first robotic arm and Im going to design all by myself. However I’m going to draw some inspo from other robotic arm designs too so it’s not entirely going to be off the dome. Currently I’ve been trying to figure out how to get my servo to fit in the base. I didn’t know it was this large (or maybe the cad model i downloaded had the wrong dimensions) I also made a custom servo horn thats basically a circular disk that can be screwed to the output shaft of the servo and then the outer M3 screws can be bolted into the base. I have no idea how Im going to be fastening each part of the arm into each other. Im pretty sure project will be needing a lot of redesigning. but trial and error is good so its whatever

Self balancing robot is a fail??
Okay so its been a long time since I’ve came back to this project to leave a devlog, but so far my self balancing robot looks like its failing. It doesn’t balance when I turn it on, and it could be due to a broken wheel or the fact that the motors are too weak. Another reason I think it might be falling is because I’m using a drill battery which is heavier than a normal one. On the software side, I don’t see any problems so I think this might be a hardware problem. Until further notice, I’m going to put this project on hold and come back to it later.

LAST (maybe) devlog of this project!
I finished the case, firmware, and PCB for this project! I’m pretty proud of what I accomplished and all the hurdles I had to get through. I probably redid my PCB like 5 times it was annoying lol. All I just need to do is complete the github repo, and then I can ship it and get my parts! I’m pretty excited to actually solder and get working on the hardware IRL. This is my first time actually something other than Arduino IDE for firmware so I’ll see how it goes when I’m flashing it onto my seeduino.

DevLog 2:

Since my microcontroller didn’t have enough pins, I decided to connect my switches in a matrix. This took longer than expected. After searching a few blogs on what this is, I got a grasp on it and succeeded in making it. This gave me the advatage of having more pins, which I used for the rotary encoder and the OLED display. BUT, as I open up the PCB checker thingy, I get hit with a lot of warnings, which I intend to fix next devlog. Otherwise, I feel pretty proud of myself for getting this much progress.

Creating the AEPad, a dedicated macropad for After Effects Users! This is my first time actually designing a PCB, so most of the time went towards actually going on the HackPad website and learning how to make the circuit board in the first place. This current version isn’t going to be the end product, since I’m thinking of adding a rotary encoder for volume control. The nine keys on the macropad will be in charge of keybinds I mostly use when video editing. Overall, this project could be pretty useful and save a lot of time when editing videos.

First Devlog on this project!

Im developing a self balancing robot that takes input from the MPU6050 component and feeds it into a PID loop that outputs motor speeds to the two TT motors on each side of the robot so that it can balance.

Currently, I don’t have a battery for this project but I am thinking about using a drill battery from my drill or buying a Lipo battery. If my drill battery seems too heavy and makes the balancing harder I’ll probably go with the Lipo battery.

Although there are a lot of tutorials on youtube on how to do this, I decided to not copy and paste the firmware from the tutorials onto Arduino IDE. I will however use them as reference for my own software. Im planning on using the PID library for this and also another library that simplifies driving the motors with the l238n motor driver.

This is a pretty simple project, but its a great way to learn how the PID control loop works. Im excited to use PID in more complex projects I will be making!
