We once saw a Romeo and Juliet production where the two families were modern-day mob families with 3-piece suits and pistols. If they made King Richard III set in this week, the famous line might be: “Hand sanitizer, hand sanitizer, my kingdom for hand sanitizer!” Even if you have a supply stashed in your prepper […]

Rk Clean Air is a gas responded device that is capable of monitoring gas leakage, smoke, and carbon monoxide leakage in the home. According to the National Fire Protection Association, “Three of every five home fire deaths resulted from fires in homes with no smoke alarms (38%) or no working smoke alarms (21%) and the death rate

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs have meant cheap supplies and sometimes even free as you gut old PCs found in the dumpster. [OneMarcFifty] decided to make a
ANOTHER PC POWER SUPPLY PROJECT Continue Reading
What’s up my friends, welcome back. What I want, is the aluminum block below to have let’s say, exactly 100 degrees. I’ll control the real temperature using a K type thermocouple. To read the data I’ll use the MAX66 75 breakout module and control the PID algorithm with and Arduino. Finally, to apply power we

Over the weekend the official Arduino Day 2020 livestream took place providing oversight of what you can expect from the Arduino platform in the near future. If you are unable to attend to catch up on the news will be pleased to know the stream is now available via YouTube view at your leisure. Check

Unless you happen to be from Finland, this is just an all too familiar situation: you’re stuck in an inescapable situation with this one person who is really more of an acquaintance than a friend, and neither of you knows who should say something in hopes of keeping a conversation going. Awkward silence is inevitable,

Just when we think we’ve peeped all the cool baby keebs out there, another think comes along. This bad boy built by [andyclymer] can be configured three different ways, depending on what kind of control you’re after. As designed, the PCB can be used as a six-switch macro keyboard, or a rotary encoder with two switches,
BABY KEYBOARD IS REALLY THREE BOARDS Continue Reading
As the Arduino blog explains “making your own medical equipment isn’t normally advisable” Johnny Lee has published a project two GitHub exploring how to transform a CPAP machine into a ventilator. Although this device “has in no way been evaluated or approved for medical use, but it does provide a starting point for experimentation”. In
DIY Arduino open source ventilator Continue Reading
Hi guys, welcome to today’s tutorial. In this tutorial we will look at how to use the TCS230 color sensor with Arduino. To demonstrate the ability of the color sensor, we will build a color detector system capable of detecting the color in front of the sensor and displaying that color on a TFT Display.
Color Detector Using TCS230 Color sensor and Arduino Continue Reading
The ARM series of processors are an industry standard of sorts for a vast array of applications. Virtually anything requiring good power or heat management, or any embedded system which needs more computing power than an 8-bit microcontroller is a place where an ARM is likely found. While they do appear in various personal computers
