Amirhossein Kazemipour, Hehui Zheng, and Robert Katzschmann of ETH Zurich’s Soft Robotics Lab began with a commercial WUJI right hand with five fingers designed for grabbing. They put a Raspberry Pi, an IMU, and a battery to its back, resulting in a package weighing 818 grams and operating without a cable. Twenty powered joints remained factory standard, four on each finger, with different lengths and a thumb positioned to one side. Lift one finger to step, and a support point disappears.
BOSGAME E5 Mini PC, priced at $186.99 with promotion code: 5400U45 (was $340), keeps showing up in deal threads because a machine this small almost never arrives with two 2.5-gigabit Ethernet ports, three 4K outputs, and a licensed copy of Windows 11 Pro for less than $300. Inside is a 15 watt laptop processor, a Ryzen 3 5400U with 4 cores and 8 threads to get the work done.
A 2019 Ford EcoSport Titanium left Ford as a short compact crossover with four wheels, Titanium trim, and a naturally aspirated 2.0-liter Duratec four-cylinder rated at 166 horsepower and 149 pound-feet. Prior ownership later sliced the body open behind the rear doors, welded in an extra rear section plus an auxiliary subframe, and added a third axle so six matching 17-inch alloy wheels now sit on Firestone WeatherGrip tires. Black paint and thin white pinstripes cover the longer sides, filler panels close the gaps, and a roof-mounted wing sits over the stretch. A side-swinging rear gate still opens onto cargo space lined in gray deep-pile carpet.
You already know how a cube is supposed to behave. Toss one onto a table and it tumbles, bounces, and settles on a face. That expectation is the reason this build exists. A maker who posts as The Tinkering Techie spent a few weeks packing motors, a reaction wheel, and a spring piston into a five inch black cube so it could do the opposite. It sits on a small foot, fires that foot, flies, rights itself in the air, and comes down on an edge, then it stays there.
Phones aren’t the best journals because most people open one to save a sentence, and then the original thought is lost, buried beneath a feed of other thoughts. Paper pads avoid this unless they disappear inside a bag or require a second round of typing. Mirza, better known as Mirza Makes, became dissatisfied with both outcomes and spent one small project transforming a brief parts list into a distraction-free machine whose sole purpose is to take notes.
