Like so many of us, [pgsanchez] has been bitten by the flight simulator bug. It’s a malady that can only be treated, but never cured — and like so many hobbies, it has a nasty tendency to spawn more hobbies. A software developer by trade, [pgsanchez] is also adept with Arduino and electronics, and his […]

Since the 1980s, we’ve seen innumerable attempts to revolutionize the way we interact with computers. Since the advent of keyboards and mice, we’ve seen everything from magic wands to electric gloves, with [Deemo Chen]’s project fitting into the latter category. The build takes on a cyberpunk aesthetic, with addressable LEDs installed along each digit. The various

When you think of high-throughput ptychographic cytometry (wait, you do think about high throughput ptychographic cytometry, right?) does it bring to mind something you can hack together from an old Blu-ray player, an Arduino, and, er, some blood? Apparently so for [Shaowei Jiang] and some of his buddies in this ACS Sensors Article. For those of you who

We’re used to seeing the Raspberry Pi crop up in a wide range of the projects we show you here, but it’s fair to say that they usually feature some sort of operating system. There’s another way to use a Pi, more akin to using a microcontroller such as the Arduino: by programming it directly,

The Raspberry Pi, although first intended as an inexpensive single-board computer for use in education, is now ubiquitous in electronics communities. Its low price as well as Linux platform and accessible GPIO make it useful in many places outside the classroom. But, if you want to abandon the ease-of-use in favor of an even lower

Input devices consisting of optical readers for punched paper tape have been around since the earliest days of computing, so why stop now? [Jürgen]’s Paper Tape Reader project connects to any modern computer over USB, acting like a serial communications device. Thanks to the device’s automatic calibration, it works with a variety of paper materials. As for

Drawing on walls is fine for children, but adults tend to get bored quickly with such antics. Even more so when they realize who is responsible for cleaning up afterwards. Instead, consider delegating those duties to a friendly helper by the name of Fumik, as [engineer2you] has done. Fumik, who looks like a cute little jellyfish,

[Görg Pflug] wrote in with his really nice graphics library. It’s got multiple layers, two text consoles, greyscale, internal halftoning, and sprites. It can pull off a number of classic graphics tricks and demos. Oh yeah, and did we mention it runs on a freaking ATtiny85 and an I2C OLED screen?! This is an amazing piece of work

Coin-operated machines have a longer history than you might think. Ancient temples used them to dispense, for example, holy water to the faithful in return for their coins. Old payphones rang a bell when you inserted a coin so the operator knew you paid. Old pinball machines had a wire to catch things with holes
COIN ACCEPTORS ARE HIGHER-TECH THAN YOU THINK Continue Reading
