24 alternatives to I designed my own 3D printer motherboard
3D printing is such a fascinating field of technology, so a couple months ago, I decided to take a deep dive and learn how they actually work! This took me to one of my very first PCB projects, a small, cheap, 3D printer motherboard. While it's not the most cutting edge board, I learned a lot and I fully documented my process designing it (https://github.com/KaiPereira/Cheetah-MX4-Mini/blob/master/J...), so other people can learn from my mistakes! It runs off of an STM32H743 MCU, has 4 TMC stepsticks with UART/SPI configurations,…
This is a custom-designed 3D printer motherboard built around an STM32H743 microcontroller in a compact 80x90mm form factor. It features four stepper motor drivers with UART/SPI configuration, thermistor and fan ports… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Prices are shown for the 1 we have checked on their own sites, 1 of them free or with a free tier.

Here's a "behind-the-scenes" look at my development of a cool sensor during my PhD (electrical engineering). This sensor is only about 1/3 of my total research for my degree and took about a year. I've been on HN for a while now and I've seen my fair share of posts about the woes of pursuing a PhD. Now that I'm done with mine I wanna share some anecdotal evidence that doing a PhD can actually be enjoyable (not necessarily easy) and also be doable in 3 years. When I started I knew I didn't want to work on something that would never leave the lab or languish in a dissertation PDF no one…

Motherboard▲388I started working on my ideas a few months ago. I've shipped 4 apps so far. I love my numbers, so every morning I'd go through the payments dashboard, analytics, bug reports, feature requests, and everything else for each app. I wished for a single place to view it all, so I built Motherboard. It runs locally in the browser and tracks any visible data point from any website with just a click. A single dashboard for everything. Life's good.

A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to…

Hey Hackers. This is a project I solo-developed that turns completed PCB assemblies into an easy to use boardview with some accompanying boardscans. There are lots of easier and better ways of doing this, but this is an experimentation to do it as cheaply as possible, with the highest quality and lowest chance of errors. The technical details are in the link. Most public boardviews are almost entirely the result of industrial espionage, other than a few encrypted subscription based software platforms that provide extensive access. The process output is released as donationware, as my main…

I bet you didn't knew you can use modelling clay (as opposed to 3d printing) to make nice devices by hand :)

Hey guys, A couple weeks ago, I was in Shenzhen, China for a hackathon and on the first day, we all used the one-day PCB fabrication to make PCB badges to wear during the event. I decided to go a little crazy and make some cool 3D alchemical-cosmological badges. It's 3 PCB's stacked on-top of each other that's connected using testpoints on each board. The innerboard has a 10 cent CH32V003 MCU that powers the WS2812B neopixels on the outer rings using the testpoints and shines through using exposed soldermask. If you have any questions about how the design works, feel free to let me know!

Hi! My name is Ben, and I recently updated my audio dev board "Sonatino" after receiving a lot of good feedback from the initial launch a year ago. I began working on this after building a few projects that required audio capabilities. I was getting tired of wiring up external DACs and amplifiers to ESP32 boards, so I decided to look for a more compact, integrated solution. The available options either had larger footprints, non-standard connectors, or features that I didn't typically need for my projects. That's when I started working on a custom PCB that could be a sort of "audio swiss…
