FINALLY, A DIFFERENTLY USELESS MACHINE

Traditionally, the useless machine is a simple one that invites passersby to switch it on. When they do, the machine somehow, some way, turns itself off; usually with a finger or finger-like object that comes out from the box in what feels like an annoyed fashion. Honestly, that’s probably part of what drives people to turn them on over and over again. But [Bart Blankendaal] has managed to turn the useless ...

CONTROLLING A BROKEN SUPER NINTENDO WITH MIDI

A Super Nintendo that has trouble showing sprites doesn’t make for a very good game system. As it turns out, Super Mario World is a lot less fun when the titular hero is invisible. So it’s no surprise that [jwotto] ended up tossing this partially functional SNES into the parts bin a few years back. But he recently came up with a project that may actually benefit from its unusual graphical issues; turning th ...

How to Build Your Own Anemometer Using Reed Switches, Hall Effect Sensor and Some Scraps on Nodemcu.

In this post, we will learn How to Build Your Own Anemometer Using Reed Switches, Hall Effect Sensor and Some Scraps on Nodemcu. Since I started with the studies of Arduino and the Maker Culture I have liked to build useful devices using junk and scrap pieces such as bottle caps, pieces of PVC, drink cans, etc. I love to give a second life to any piece or any material. A large part of the materials used her ...

PLAY A GAME OF MULTIMETER

There are many different single board computers that are general purpose, but there’s another breed targeted at specific applications. One such is the Clockworkpi, a handheld Game Boy-style games console, which may be aimed at gamers but has just as much ability to do all the usual SBC stuff. It’s something [UncannyFlanigan] has demonstrated, by turning the Clockworkpi into a multimeter. And it’s not just a ...

AN ARDUINO CONTROLLER FOR HOT AIR HANDLES

In general, the cost of electronic components and the tools used to fiddle with them have been dropping steadily over the last decade or so. But there will always be bargain-hunting hackers who are looking to get things even cheaper. Case in point, hot air rework stations. You can pick up one of the common 858D stations for as little as $40 USD, but that didn’t keep [MakerBR] from creating an Arduino contro ...

3D-PRINTED FLIGHT CONTROLS USE MAGNETS FOR ENHANCED FLIGHT SIMULATOR 2020 EXPERIENCE

We have seen quite a few DIY joystick designs that use Hall effect sensors, but [Akaki]’s controller designs (YouTube video, embedded below) really make the most of 3D printing to avoid the need for any other type of fabrication. He’s been busy using them to enhance his Microsoft Flight Simulator 2020 experience, and shares not just his joystick design, but makes it a three-pack with designs for throttle an ...

EASY-TO-USE MUSIC PLAYER RELIES ON RFID

Microwaves used to be simple to use. Set the dial for the desired time, and hit start. Then, everything went digital and the average microwave now takes between four and six button presses in precise order just to start heating. Music players have gone down a similar path, and those that grew up in the era of vinyl records can find modern digital media simply too hard to work with. To solve this problem, [a ...

OVER-ENGINEERED SINGLE BUTTON TIMER

Feature creep is typically something to be avoided, since watching a relatively simple project balloon into a rat’s nest of complexity often leads to ineffective, or even abandoned, projects. On the other hand, if you can maintain a tight focus, it’s not always a bad thing. [cbm80Amiga] shows us how to drill down and add specific features in this single-button timer without losing focus on what the original ...
