A UK maker has transformed a collection of discarded disposable vapes into a functional car. Chris Doel, the man behind a number of projects that recycle vape batteries, has recently installed his 500-cell lithium pack in a small electric vehicle and driven it on public roads.

Kiran Patil, an aerospace engineer from Bangalore, India, is receiving a lot of attention for the small arcade game he made in his studio. Patil’s device has officially been recognized by Guinness World Records as “the world’s smallest arcade machine.” The compact box is only 24.85mm tall, 15.25mm long, and 15.1mm wide, making it smaller than a regular AA battery.
Liquid oxygen is used in rockets and treated with care in laboratories, but it’s not something that people think about in everyday life. Except for one maker who was interested as to why this was the case, so he decided to make some at home and examine what makes people so cautious about it.
Matthew Perks has truly outdone himself with his new invention, a highly portable powerhouse surrounded by one of the world’s brightest LEDs. The device, known as the LED supernova, takes 1.5 kilowatts of power and converts it into a dangerously eye-searing 120,000 lumens, all in a compact box weighing only 25 kg and remaining (amazingly) portable.
In the early 1990s, handheld gaming was booming, and two absolute titans ruled the roost: Nintendo’s Game Boy and SEGA’s Game Gear. These two were extremely expensive, typically costing more than $100 each ($225 today), so only young gamers with deep pockets could get in on the action. Then the Hartung Game Master appeared unexpectedly from Germany.
A Scholastic Book Fair cash register appears for sale on eBay, and Michael MJD simply wants to get his hands on it for a closer look. It turns out to be a PAX E500 POS terminal that Scholastic had customized for their traveling sales events. These devices would process orders for books, posters, pencils, and anything else was piled up in those brief, generally chaotic classroom installations.
Fletcher Heisler was beaten by chess hustlers in the park, so he wanted revenge, but regular practice wasn’t cutting it. So he reasoned, “Maybe I need some negative reinforcement,” thus taser chess was born, or a chessboard that would literally penalize you for making blunders by delivering an electric shock.
JVC’s W-VHS VCR made a splash in the analog tape world when it debuted in 1993, and with good cause. Engineers at the business decided to go all out on the tried-and-true VHS cassette casing, upgrading the tape and devising some ingenious ways to load high definition video onto it a few years before digital formats truly took hold. From the outside, the product appeared to be any ordinary VCR, but, surprise, under the hood, it is managing signals far beyond the capabilities of a standard VHS.
A roll of Scotch tape can do some truly unexpected things, such as completely replacing a camera lens. Maker okooptics puts this to the test in a recent project, transforming an ordinary sensor into a functioning camera using only Scotch tape, smart rigging, and some math after the fact.

A cassette tape squeezes a snapshot and then spits it out in an altered state. Jordan Blanchard, the mastermind behind this project, calls it the Digital-Analog Tape Picture Camera. It’s a handheld device that digitally captures still images, converts them to sound, saves them to standard cassette tapes, and then allows you to view them.
