AUTOMATING HAND SANITIZER — IF YOU CAN FIND ANY

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 cache, you have to touch the bottle so you could cross-contaminate with other users. Public pla ...

ROBOT FIGHTS FIRE WITH IR

Fighting fire with robots may take jobs away from humans, but it can also save lives. [Mell Bell Electronics] has built a (supervised) kid-friendly version of a firefighting robot that extinguishes flames by chasing them down and blowing them out. This hyper-vigilant robot is always on the lookout for fire, and doesn’t waste movement on anything else. As soon as it detects the presence of a flame, it center ...

Simple Automated Point to Point Model Railroad Running Two Trains

Arduino microcontrollers are a great way of automating model railroad layouts due to their low-cost availability, open-source hardware and software and a large community to help you. For model railroads, Arduino microcontrollers can prove to be a great resource for automating their layouts in a simple and cost-effective way. This project is such an example of automation of a multi-point model railroad layou ...

GRAVITY-DEFYING WATER DROPLET FOUNTAIN GETS AN UPGRADE

When we last saw [isaac879]’s levitating RGB time fountain, it was made of wood which meant that it would absorb water and didn’t really show off the effect very well. His new version solves this problem with an acrylic case, new PCB and an updated circuit. Like the original, this project drops water past strobing RGB LEDs creating an illusion of levitating, undulating colored water droplets. The pump at th ...

Ultrasonic Mapmaker Using Arduino and MatLab

Vision is one of the most exciting senses you can endow on your robot. The ability to perceive obstacles allows a robot to make an educated decision regarding further movements. However, it is also not the easiest senses to implement for a few reasons. Firstly, vision can be abstracted to a two-dimensional vector when it comes to computing, as opposed to a single dimensional scalar such as, say, temperature ...

A SIMPLE AUGER PET FEEDER

Pet feeders are a popular maker project. One can speculate that this shows the great self-confidence common to the maker set, who are willing to trust their own work to keep their animal companions alive for many days at a a time. [Darren Tarbard] is one such maker, who put together this simple auger build. The project consists of a hopper for dry pet food, into which a screw auger is inserted. Both parts a ...

DIY Smart Follow Me Drone With Camera (Arduino Based)

Drones are very popular toys and tools these days. You can find professional and even beginner drones and flying gadgets in the market. I have four drones (quadcopters and hexcopters), because I love everything that flies, but the 200th flight isn't so interesting and starts to be boring, so I decided that I will build my own drone with some extra feutures. I like to program Arduino and design circuits and ...
