Using hardware I2C on an ESP32? Do you need to connect multiple I2C devices with the same address? Normally, you wouldn’t be able to do that without extra parts, but …read more Continue reading Avoid I2C Address Conflicts On ESP32 By Pin Muxing
A few days ago, KiCad 8 was released, and it’s a straight upgrade to any PCB designer’s quality of life. There’s a blog post as usual, and, this year, there’s …read more Continue reading KiCad 8 Makes Your Life Better Without Caveats
Ethernet is ubiquitous, fast, and simple. You only need two diffpairs (four wires) to establish a 100Mbit link, the hardware is everywhere, you can do Ethernet over long distances easily, …read more Continue reading Ethernet For Hackers: The Very Basics
Flexible cables and flex PCBs are wonderful. You could choose to carefully make a cable bundle out of ten wires and try to squish them to have a thin footprint …read more Continue reading Friendly Flexible Circuits: The Cables
We started with figuring out HID descriptors a week ago, and I’ve shown you how to send raw HID packets using a MicroPython fork. We do still have the task …read more Continue reading Human-Interfacing Devices: Packing for the Descriptor Heist
Today, we’ll build our own input devices. And they will be easy to create and write firmware for, they will work perfectly, and they will be cross-platform. We can do …read more Continue reading Human-Interfacing Devices: The Descriptor Heist
You might have seen old display panels, from 3″ to 10″, with 40-pin FFC connectors where every pin seems to be used for some data signal. We call these displays …read more Continue reading Displays We Love Hacking: Parallel RGB
Throughout the last few years’ time, I’ve been seeing sparks of an eternal discussion here and there. It’s a nuanced one, but if I could summarize, it’s about different feature …read more Continue reading Ask Hackaday: What About Imperfect Features?
We often use linear regulators in our designs. They are cheap and simple – you put the regulator chip itself on the board, add two capacitors, and get a voltage. …read more Continue reading Switching Regulators For Dummies
Intel ME, AMT, SMT, V-Pro… All of these acronyms are kind of intimidating, all we know about them is that they are tied to remote control technologies rooted deep in …read more Continue reading Enabling Intel AMT For BIOS-over-WiFi
