If you enjoy watching skilled assembly of small mechanical systems with electronics to match, then make some time to watch [Max Imagination] transform a Hot Wheels car into a 1/64th …read more Continue reading Hot Wheel Car Becomes 1/64 Scale Micro RC Car, Complete With Camera
Some things are small and fragile enough that they cannot be held or touched by even the steadiest of hands. Such cases call for a micromanipulator, and [BYU CMR]’s DIY …read more Continue reading Micromanipulator Touches The Tiny Things, Cheaply
The PiPi Mherkin really, really can’t get much smaller. The diminutive keyboard design mounts directly to the Pi Pico responsible for driving it, has a similar footprint, and is only …read more Continue reading DIY Keyboard Can’t Get Much Smaller
You’ve probably heard of micro-drones, perhaps even nano-drones, but there research institutions that shrink these machines down to the size of insects. Leading from the [Wiss Institute For Biologically Inspired Engineering] at Harvard University, a team of researchers have developed a miniscule robot that — after a quick dip — literally explodes out of the water.
To assist with the take off, RoboBee has four buoyant outriggers to keep it near the water’s surface as it uses electrolysis to brew oxyhydrogen in its gas chamber. Once enough of the combustible gas has accumulated — pushing the robot’s wings out of …read more

[David Brown]’s entry for The Hackaday Prize is a design for a tool that normally exists only as an expensive piece of industrial equipment; out of the reach of normal experimenters, in other words. That tool is a 6-axis micro manipulator and is essentially a small robotic actuator that is capable of very small, very precise movements. It uses 3D printed parts and low-cost components.
The manipulator consists of six identical actuators, each consisting of a single piece of SLS 3D printed nylon with a custom PCB to control a motor and read positional feedback. The motor moves the central …read more

FPV drones are a fun but often costly hobby for beginners. Opting for a smaller drone will reduce the chance of damaging the drone when one invariably crashes and the smaller props are also a lot safer if there are any innocent bystanders. YouTuber and Instructables user [Constructed] wanted a cheap FPV capable drone that they could comfortably fly in-and-out of doors, so of course they built their own.
Once the drone’s frame was 3D printed, the most complex part about soldering four small-yet-powerful 8.5 mm motors to the Micro Scisky control board is ensuring that you attach …read more
The first of the BBC Micro Bits are slowly making their ways into hacker circulation, as is to be expected for any inexpensive educational gadget (see: Raspberry Pi). [Martin] was able to get his hands on one and created the “hello world” of LED displays: he created a playable game of snake that runs on this tiny board.
For those new to the scene, the Micro Bit is the latest in embedded ARM systems. It has a 23-pin connector for inputs and outputs, it has Bluetooth and USB connectivity, a wealth of sensors, and a 25-LED display. That’s small for …read more
