Word clocks are a cool way to tell the time. While they could have probably been built back in the 1960s with a bunch of relays and bulbs, they really only came into their own in the LED-everything era. [Vatsal Agarwal] built one of his own, showcasing his maker credentials. It’s a build that relies on good woodworking practices from the ground up. Maple wood is used for the frame, cut and prepared on a mit ...

One of the more disappointing news stories of 2019 was the fire at the Notre Dame cathedral. Widely considered a building of great historical importance and architectural merit, it was heavily damaged and will take significant time and resources to repair. Fundamentally though, if you’re reading this, that’s probably someone else’s job. Instead, why not just build your own Notre Dame out of gingerbread at h ...

This project turns on and turns off a laser LED after every second. It can also monitor its own supply voltage level. The circuit can be extended for use as an audio-visual alarm system for security applications. Keyes KY-008 laser transmitter module is available at www.ebay.com. But there is a lot of confusion regarding this particular module; it is impossible to find its datasheet or any kind of related d ...

The YouTube channel DIY Builder has published and created a DIY Arduino laser engraver which is powered by an Arduino Nano development board and is fitted with a 200-250mW 650nm Laser Module. Check out the video below to learn more about the DIY Arduino laser engraver constructed using the innards from an old PC DVD player. A full list of all components has been provided enabling you to get everything ready ...

LAKE WALES Fla.—Graphene is easily grown with chemical vapor deposition (CVD) on copper foil, but a simple way of etching out the necessary circuit patterns and transferring them to a non-metallic substrate has eluded engineers. Now researchers at the University of Illinois (Urbana-Champaign) claim to have a one-step room temperature process for quickly patterning and transferring graphene circuits to flexi ...

So this Lazy Old Geek purchased a Laser Cross. I created a manual leveling Laser Cross to use for aligning stuff on my drill press: http://www.instructables.com/id/ManualLevelingLaserCross/ Well, being a Geek I decided to make an automated platform that adjusts automatically with an Arduino. Well, the picture may look a little scary but I’ll break it down into little bitty parts. Step 1: Parts Lists Parts L ...

Abstract Established and already commercialized energetic materials, such as those based on Ni/Al for joining, lack the adequate combination of high energy density and ductile reaction products. To join components, this combination is required for mechanically reliable bonds. In addition to the improvement of existing technologies, expansion into new fields of application can also be anticipated which trigg ...

[highlight bgcolor="ffbb00"]I have collected 2 methods to create laser range finder, one is very simple but for hobbiest the first one using arduino clock but it comes with errors. Its just to conceptulize how we can create range finder. The second one with the The 7558 and 7555 Series Rangefinder/Processor professional one. It uses already built kits we only have to use these to developer arduino based ran ...

About this project This is a Robot Arm with 5-axis range of motion allowing movements similar to assembly line robots. It was designed to offer the highest quality while remaining one of the most affordable robotic arms on the market. Three years ago, we created MandleBot, a 5-axis aluminum robotic arm currently being used in schools, robotics clubs, summer camps and even factories. We have enjoyed sharing ...

This project uses an Arduino, a pair of speakers, and a laser pointer to create a laser projector able to trace out designs in a dark room. To power it, I've cannibalized a PC ATX power supply capable of delivering plenty of current for the speakers. Most of this project was directly adapted from the excellent Arduino Laser Show with Full X-Y Control by Rich Olson / nothinglabs. Step 1: The Big Idea Laser p ...

For this dandy little project you'll need: Arduino - I'm using an Arduino Uno a 3 x 4 keypad a 16 x 2 LCD screen a laser module/sensor a light dependent resistor (LDR) a buzzer 3 x 220 ohm resistors 1 x 10K resistor 1 x 10k potentiometer (optional, it's to adjust the LCD screen brightness) an LED and a ton of wires! So, first thing I did was to get the LCD and keypad working together. For this I pretended t ...
