Many years ago (September 2009) I made a simple bench power supply using an LT1083 7.5A linear regulator with adjustable output voltage designed to be used with a 19.5V 3.42A laptop power supply. It still works fine after years of abuse, but my choice of output power connectors was poor (3 pin headers, the sort …
Often used to make rugs, tufting is a process wherein a hollow needle is used to cram thread or yarn into fabric in some kind of pattern. This can be done by hand, with a gun, or with big machines. Some machines are set up to punch the same pattern quickly over and over again, …

The ESP32 has about 4MB of internal flash memory and since the data stored within the flash memory is retained even when power is recycled, it becomes super useful for applications where you need to keep certain amount of data even after power off. For today’s tutorial, we will learn how to read and write …
The Fallout series of games has a variety of ridiculous weapons, not least the Super Sledge — a rocket propelled sledgehammer that looks about as dangerous for the wielder as it does for the opponent. [JAIRUS OF ALL] decided he had to recreate this build in real life, risks be damned. Unwilling to go the …
Charlieplexing. Aside from being a fancy word it is a technique for driving multiple LEDs with relatively few pins on a microcontroller. It allows you to drive N*(N-1) LEDs with just N pins without requiring any additional hardware, making it a quick, cheap and easy way to add multiple LEDs to your arduino projects. Throughout …

There are many racing wheels on the market for the budding sim enthusiast. Unfortunately, lower end models tend to have a limited range of motion and ship with cheap plastic wheels that don’t feel good in the hand. As always, if what’s on the shelf doesn’t meet your needs, you can always build your own. [ilge]’s …
Microcontroller-based products sometimes require rotary switches. As many microcontrollers have an onboard ADC, it is easy to replace the rotary switch with a low cost potentiometer, when a rotary switch is too expensive or unavailable. Although digitizing a potentiometer setting to act like a switch requires only a few instructions, an immediate problem is that …
No longer will you have to pay hundreds of dollars for a heart rate monitor! The Smart Heart Monitor will be able to do all of your cardiac measuring needs for you! The Smart Heart Monitor measures the user’s heartbeat using an LED and a very sensitive photo-resistor attached to the user’s ear. A light …
While we’re still far away from returning to a pre-Corona everyday life, people seem to have accepted that toilet paper will neither magically cease to exist, nor become our new global currency. But back at the height of its madness, like most of us, [Jelle Vermandere] found himself in front of empty shelves, and the …

Back Story My brother has Funko POP figures that represent his characters that his friends play most often in video games. We thought that it would be cool if they had a display case that would have LEDs in it to represent their status on Steam. So with my previous experience with Arduino, Steam API, …
