Have you ever looked at a small development board like an Arduino or an ESP8266 board and thought you’d like one with just a few different features? Well, [Kai] has put out a fantastic guide on how to make an RP2040 dev board that’s all your own. Development boards are super useful for prototyping a […]
Breadboards are great, but as the world moves more and more to having SMD as a standard, prototyping straight PCBs is becoming more common. If you’re mailing off to China for your PCBs, it’s shockingly quick for what it is, but a one-week turnaround is not “rapid prototyping”. [Stephen Hawes] has been on a quest […]
Sometimes when you’re making a PCB that you plan on programming over USB, but you only plan on plugging in a couple of times, it would be nice to make that connection without another BOM item. Over on GitHub [AnasMalas] has released a PCB edge USB-C connection symbol/footprint to do just that! This isn’t the […]
In the past week, a few forum and Reddit threads have popped up, with people stating that JLCPCB has emailed them with a notice, saying their accounts are set up for terminations after an assessment by JLCPCB’s “Risk Control Team”. Reasons given are vague, the terminations are non-appealable, and if you’re planning a JLCPCB order […]
A business card is a convenient way to share your contact information, but it’s unfortunately prone to being thrown away or forgotten. PCB business cards try to get around this problem, but while impressive, most won’t keep the recipient engaged for a very long time. [Cole Olsen]’s macro pad business card, on the other hand, […]
Here at Hackaday HQ, we all have opinions about the way we like to do things. And no surprise, this extends to the way we like to lay out circuits in schematics. So when we were discussing our own takes on this piece on suggested schematic standards, it was maybe more surprising how much we […]
If you’ve ever lost gear to lightning or power spikes, you know what a pain they are. Out in rural Arkansas, where [vinthewrench] lives, the grid is more chaos than comfort – especially when storms hit. So, he dug into the problem after watching a cheap AC-DC module quite literally melt down. The full story, […]
Facing the horrifying realization that he’s going to graduate soon, EE student [Colin Jackson] AKA [Electronics Guy] needed a business card. Not just any business card: a PCB business card. Not just any PCB business card: a PCB business card that can play pong. [Colin] was heavily inspired by the card [Ben Eater] was handing […]
