Cablecams are a lot of fun, but they’re not inexpensive, even if you need just something small for your action camera. There are commercial solutions out there, like the Wiral Lite, but they’re pretty expensive for what they are. Perhaps even more so than the camera you’re mounting to it. When Kasper at MAKESOME was asked by his friend […]

One of the disadvantages of having cheap WiFi-capable boards like those based on the ESP32 is that you have to update them. If you have even a few in every room of your house, it can be a pain to pull them out and connect them to a cable for programming. Over the air programming […]

[Ivan] seems to enjoy making 3D printed vehicles with tracks. His latest one uses 50 servo motors to draw patterns in the sand at the beach. You can see it work in the video below. Well, more accurately you can see it not work and then work as the first iteration didn’t go exactly as planned. An […]

This instructable explains how to make a tilt compensated compass using an Arduino UNO R3, an LCD display, and an IvenSense MPU-9250 multi-chip-module that contains an MPU-6050 accelerometer / gyro and an AK8963 magnetometer within the same package. The LCD simultaneously displays the Heading, (P)itch, and (R)oll. The heading accuracy is within 2 degrees depending […]

This is a version 2.0 of one of my first forays into Arduino and DIY MIDI programming. I’ve developed my skills in prototyping and design so I thought it would be a good demonstration of process and progression. With a more informed design process I recycled the buttons from my first attempt and set off […]

Liquids or other objects appear colored because theyreflect or transmit certain colors and in turn swallow (absorb) others. With a so-called photometer, those colors (wavelengths) can be determined, which are absorbed by liquids. The basic principle is simple: with a LED of a certain color you first shine through a cuvette filled with water or […]

This Arduino based digital clock is synchronized by the 60Hz power line. It has a simple and inexpensive common anode 4 digit 7 segment display which shows hours and minutes. It uses a cross over detector to detect when the incoming 60Hz sine wave crosses the zero voltage point and derives a 60 Hz square […]

Where won’t they put a TV these days? We’ve even seen one creeping behind semi-transparent mirror film in the ladies’ room of a sports bar, though that one didn’t last long. Up until that moment, we had never wished so hard for a TV-B-Gone, especially one as small and powerful as this DIY version by [Shane]. […]

Today the official Arduino development team have rolled out a new update to the Arduino CLI, adding some new exciting features in version 0.11.0. New features include Command-line completion, External programmer support and Internationalization and localization support (i18n). “Finally, the autocompletion feature has landed! With this functionality, the program automatically fills in partially typed commands […]

Cheap 433 MHz wireless switches are a tempting way to enter the world of home automation, but without dedicated hardware, they can be less easy to control from a PC. That’s the position [TheStaticTurtle] was in, so the solution was obvious. Build a USB 433 MHz transceiver. At the computer end is a CH340 USB-to-serial chip […]
