MSX Revival on an ESP32-S3 Shows How Far Tiny Hardware Can Be Pushed
A compact microcontroller driving VGA while emulating a classic home-computer platform is a neat technical marker: embedded chips are now powerful enough to host surprisingly complete retro systems.
When a Tiny Controller Meets Ultrasound, the Lab Gets Cheaper
A Pico-driven acoustic demo is not a security incident, but it does show how low-cost hardware is making precise signal experiments easier to build, repeat, and study.
How a Small Demo Turns Hardware Limits Into the Main Event
A Pi Pico showcase built around the RP2350 and Linus Akesson’s “Sum Ergo Demonstrato” is a reminder that constrained hardware can make ordinary engineering look extraordinary.
A Pocket Build That Blurs the Line Between Toy and Tiny Computer
An STM32 handheld with OpenGL and “all the classics” is a neat hardware milestone, but the most revealing detail is that its core is described as a microprocessor, not a microcontroller.
A Budget Display Board, a Memory Boost, and the Thin Line Between Gadget and Game Machine
A compact CYD project with boosted PSRAM shows how small hardware changes can shift a cheap board into a much more ambitious role, even when the build details stay sparse.
Qualcomm’s QCC74x Enters a Busy Corner of the Wireless Chip Market
The QCC74x is being discussed in the same breath as Espressif’s ESP32 line, a comparison that puts connectivity, developer appeal, and embedded security into the same frame.
How an 8-Bit Microcontroller Turned into a Web Service
An AVR board serving web pages is a useful reminder that once even tiny hardware speaks HTTP, it inherits the discipline, and the exposure, of any networked service.
A Cookie That Runs on Code: Inside a Tiny ESP32 Maker Build
A playful e-fortune cookie project turns a familiar snack wrapper into a compact lesson in how small embedded builds blend hardware, software, and delight.
Inside the Tiny Add-On That Gives a Classic ZX Spectrum Game a New Map
A retro hardware project built around Atic Atac shows how modern microcontrollers can extend 1980s home computers without changing what made them iconic.
When a Tiny Chip Becomes the Front Door: The ESP32 VPN Experiment
A home-network tunnel on an ESP32 is technically possible, but the real security story is how much trust a microcontroller can carry before memory, firmware, and routing limits start to matter.
The Card That Refuses to Be Just a Card
A maker-built computer pushes the ID-1 form factor to its physical edge, turning thickness, flex, and power budget into the real engineering battleground.
When the Crowd Flips the Switch: How Twitch Chat Took Over a Living Room Lightshow
An enterprising coder invites the internet to control his home’s LEDs, blurring the line between entertainment, hacking, and remote access.
Sleep or Die: The Power Battle Inside Your Battery-Powered Gadgets
As the race for greener devices heats up, hackers and engineers are rethinking how microcontrollers sleep-and who really controls the on/off switch.
Reanimating the Arduino: KernelUNO Brings a Taste of OS to the Underdog Board
Can a humble microcontroller from yesteryear handle its own operating system? A new project pushes the Arduino Uno beyond its limits.
Silent Signals: How NFC Unlocks Battery-Free Wake-Up Calls for MCUs
A hacker’s ingenious use of Near Field Communication could reshape how microcontrollers conserve energy-and when they wake up.
