Collaborate Disseminate
Microcontroller dev boards are wonderfully useful items, in testament to which most of us maintain an ample collection of the things. But dragging one out to do a simple job …read more Continue reading USB Dongle Brings Python-Controlled GPIO to the Desktop
The ESP32 has been a go-to microcontroller platform for a while now, thanks to its versatile capabilities, integrated Wi-Fi and Bluetooth connectivity, and low power consumption. It’s ideal for a …read more Continue reading Spying on the ESP32’s GPIO
When it comes to design decisions, we’re often advised to “think outside the box.” It’s generally good advice, if a bit abstract — it could really mean anything. But it …read more Continue reading Odd Inputs and Peculiar Peripherals: RoenDi Smart Knob Thinks Outside the Box
Like many Hackaday readers, [Steven Stallion] has had his eyes on the replica PDP-11 created by [Oscar Vermeulen] for some time now, and this summer he finally got the opportunity …read more Continue reading Upgrade Board Adds GPIO Pins To Your Replica PDP-11
When the first Raspberry Pi rolled off the production line back in 2012 it sported a 26-pin expansion header that seemed to conceal endless possibilities. A later upgrade to the …read more Continue reading Run Out Of GPIO On Your Pi? Don’t Despair!
Although protocols like I2C and SPI are great for communicating between embedded devices and their peripherals, it can be a pain to interface these low-level digital interfaces to a PC. …read more Continue reading Bridging the PC and Embedded Worlds with Pico and Python
The good news it that you can now buy a pretty decent laptop that’s based around the Raspberry Pi Compute Module (CM). The bad news is that it was conceived before anyone knew the interface was going to change for the new CM4, so it doesn’t have any of the …read more

By and large, the Raspberry Pi is a computer that eschews legacy interfaces. Primarily relying on SD cards for storage and USB ports for further expansion, magnetic hard drives are a rare sight. However, [Manawyrm] decided that some 40-pin goodness was in order, and set to making a PATA IDE …read more

We love the simplicity of Arduino for focused tasks, we love how Raspberry Pi GPIO pins open a doorway to a wide world of peripherals, and we love the software ecosystem of Intel’s x86 instruction set. It’s great that some products manage to combine all of them together into a …read more

We’d wager most hackers are familiar with FTDI as the manufacturer of the gold standard USB-UART interfaces. Before parts like the ultra cheap CH340 and CP2102 became common, if you needed to turn a USB cable into a TTL UART device, “an FTDI” (probably an FT232RL) was the way to …read more
