Make use of an ad hoc module by AMS in order to make a precious Arduino based tool. It will allow analysis of materials, including food and drink, through the spectrum obtained with a light stimulus and a sensor, and shown on the serial monitor. Spectrometry is an analysis technique that enables the identification…
“I built this costume for the Edmonton Comic Expo 2018, but also because I have kids, nieces, and nephews, and a costume like this scores mega points, doesn’t it?” This amazing creation requires both a child and an adult to make it work. The suit is beautifully designed by creator Gridlock Cosplay, and features an…
How To Mechatronics has come up with a bender that not only twists wire left and right, but can rotate to create three-dimensional shapes. The 3d wire bending machine is powered by an Arduino Nano, which controls three stepper motors for wire manipulation via DRV8825 driver boards. A servo motor is also implemented in order…
Maker Peter Balch has been able to turn an Arduino Nano into an oscilloscope the size of a matchbox. This oscilloscope costs the price of an Arduino Nano (£2 and a display (£3) plus a few pence for resistors. The simplest version of this device, which he calls the ArdOsc, displays data on a computer…
Last year I’ve made two door lock projects. One was the keypad project and the second one was an RFID door lock project each with a 3D printed case and a servo to open the door. Today I have a new one and probably the last door lock project on this channel. This is a…
The Shy Machine is a motion activated, sound reactive, environmentally adaptive and arduino-powered kinetic light sculpture. When it detects motion via a PIR sensor, the shell-like robot takes a reading of the ambient sound level using an internal microphone. If things are sufficiently quiet, it opens up using a stepper motor and lead screw, revealing…
If you need a DC Motor for your next project, you can obviously buy it or you can build it! In order to assist with the winding process for a self-built motor, on thingiverse you can find an innovative fixture with two stepper motors and an Arduino Nano for control. Component needed : Arduino nano…
While making a clock isn’t an uncommon hacker pursuit, this Arduino-controlled device uses a series of wires to both power and support the clock’s four digits from a bent brass frame. This gives it a decidedly web-like appearance, so much so that Andy Pugh – the maker – notes it’s reminiscent of the cobweb writing…
Split-flap displays show information using characters changed by an electric motor. This is exactly what “gabbapeople” has chosen to show the informations of its weather forecast station. I am a fan of the XOD visual programming environment. With the 0.22.0 version, XOD entered the Internet of things. So I have an excellent opportunity to create a…
“This is fun, makes me smile, and feels good.” Sometimes, the best robots are less functional and more emotional. If you agree these words, you should definitely build your own Hungry Robot using Arduino along with some open-source code and freely available 3D printing model files. All you need to build it is: 1 x…
Light painting: there’s something that never gets old about waving lights around in a long exposure photo. Whilst most light paintings are single shots, some artists painstakingly create frame-by-frame animations. This is pretty hard to do when moving a light around by hand: it’s mostly guesswork, as it’s difficult to see the results of your…
Smartwatches can keep us informed of incoming information at a glance, but responding still takes the use of another hand, potentially occupied by other tasks. But something is about to change thanks to the WrisText system. We present WrisText – a one-handed text entry technique for smartwatches using the joystick-like motion of the wrist. A user enters…
