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 ...

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 ...

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 ...

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 ...

If your plants could do with a little TLC you may be interested in a new add-on board unveiled by Adafruit this week in the form of the Bonsai Buckaroo plant care development board, which will soon be available to purchase directly from the Adafruit online store. Check out the quick overview video below to learn more about the small add-on designed for micro:bit or CLUE boards. ““Bolt it on with 5 screws to ...

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 ...

Comma.ai is a self-driving car startup founded by George Hotz, the American hacker known for unlocking the iPhone and the PlayStation 3. Comma AI who originally wanted to build self-driving car kit, canceled their initial project due to safety concerns from NHTSA but later open-source their project and has now launched a Panda, an On-Board Diagnostics (OBD) II adapter that is expected to expose a car sensor ...

Snekboard is an open hardware development board that’s designed to let you hook up to LEGO Power Functions motors and switches so you can build robots out of LEGO and control them with CircuitPython or the simpler Snek programming language. Measuring just 48 x 48 mm the same size as 6 x 6 LEGO studs the small yet powerful develop on board can be used to control a wide variety of different functions and is p ...

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 ...

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 ...

This instructable is the written version of my "Arduino : How To Control Stepper Motor via Bluetooth (with Smartphone)" In this project we will control a Stepper motor with a smartphone via bluetooth. My YouTube Channel First, you should see the following Instructable: How to Control a Stepper Motor With L293D Motor Driver Step 1: Tutorial https://youtu.be/EpLR4I9WYOU The Stepper motor used here is a rusty ...
