Ever since I started designing PCBs, one thing I really struggled with is getting the real world parts I want to use into my design software, it's only recently that I got to a nice workflow with my tool of choice Autodesk Fusion, here is a tutorial on...

Modifying generic automatic cat feeders to much simpler web interface using ESP8266!
 | I got so fed up with the stupid interface on the front of my automatic cat feeders that I decided to make a web interface and use the ESP8266 to control them. They are very simple devices. Across two different brands of feeders I have they use the same internal mechanism, so this should work pretty universally across all generic-looking cat feeders... I was going to design a custom PCB but the circuit is so simple it was pointless and would've taken weeks to arrive. I cut the original wiring harness and crimped on JST-XH connectors to make it look somewhat professional. cat feeder from brand #1 wired to my board cat feeder from brand #2 wired to my board The prefboard I made (I made 3x of them) You can check out the code and some more images of the feeders and board (front/back/etc) here: [link] [comments] |

My latest Project: an RP2040 board called Nova
 | Hey everyone! I’m excited to share my latest project: a tiny, open-source RP2040-based board with an integrated addressable LED matrix. It’s built on a 4-layer PCB, and the LEDs are ultra-small (just 1mm x 1mm each), using WS2812 for full addressability. [link] [comments] |

My first inverter!
 | I started tinkering with transistors because it’s what I am mostly learning this semester. First I tried to control output using the PWM pin from my RPi. After that I got the idea of building an RC car and doing the input to the motor from scratch. My first working test is an H-bridge using 4 npn and 2 pnp transistors with modulation through the Q2 and Q4 npn. Right now I can generate a rectangular wave. The 2 LEDs are in opposite directions, so a positive voltage turns one and a negative the other. The This week I want to bring it to uni and test the sinusoidal generation and efficiency with the oscilloscope. [link] [comments] |
