We emulate the TDG series remote controls using the GSM Shield. It’s not been long since we presented our GSM shield for GSM/GPRS modules SIMCom, QUECTEL, FIBOCOM etc. that was born to be incorporated in Arduino-based projects involving cellular connectivity; now it’s time to move on to the first practical application, which in this case…
Over the last few months we’ve all been forced to communicate online rather than in person. As a student, most of my lectures turned into Zoom meetings, and the same happened to my tutoring hours. In the next few weeks, many students of all ages will go back to their schools or universities but many…
This instructable explains how to make an anemometer from an Arduino Uno R3, two VL6180X laser distance modules, and a section of plastic drain pipe or similar. Processing3 is used to display the wind speed and wind direction. The wind direction is independent of the pipe dimensions. The sensitivity to wind speed depends on the…
This is an interactive Christmas diorama which, when you press a button/switch, lights up with Christmas colors and music! More info
It is normal that school is challenging and, at times, deeply so! But sometimes things really do get out of control, and students, unable to communicate to their teachers and advisors how they are feeling, can fall over the edge. It is at this point–when students are burnt out, sleep deprived, and even physically…
Lasers have always intrigued me. I have two Helium-Neon Lasers (gas discharge, not solid state), one red the other green. I also have several laser pointers. I like lasers. Several years ago I came across an instructable that showed that you could take the narrow beam of a laser and spread it out into…
This interactive table light fixture was inspired by the work of famous mid-century designer, Gerrit Rietveld. Each panel is touch-activated and is independent from one another, allowing for endless color possibilities. Have fun making and playing with it! More info
Mathematical relations and patterns are found all around us in our daily lives as well as in nature. These patterns can range from simple to complicated and harmonious to chaotic. No matter what type of pattern we encounter, these geometric figures have intrigued so much that and we have developed a fond appreciation of…
Every music practitioner desires a stage, but not everyone has a stage, and not everyone likes to participate in that kind of public stage. I want to create a new experience for music lovers. Whether it is practicing musical instruments, karaoke, or playing music, the stage will change different effects according to the rhythm….
Motion detector based on the Doppler effect, made by combining a specific sensor with a circuit that amplifies the output signal. Now the devices used in presence and movement detection systems, to be combined with automations for opening doors and turnstiles but also with anti-theft and anti-intrusion systems, stand out passive infrared radars (otherwise called…
It solves the problem of pitch loss that can trouble 3D printers and which, especially in large printers that require many hours to print parts, can mean huge losses of time and money. In previous posts we presented a stepper motor driver, which we named MotorFish, whose special feature is to work in closed loop…
Let’s describe the firmware of the stepper motor feedback controller and test it on the 3D printer. (Read the first post) In the limits of non-retroactive stepper motor control is that in applications for the drive of machines, CNC milling machines or 3D printers, the positioning can be affected by an error that makes it…
