This instructable describes how to make an ultrasonic “radar-style” display using an Arduino microcontroller, an ultrasonic sensor, and a small stepping motor. An optional sensor modification allows multiple objects to be detected with each ping. Construction is simple … all you need are two drills, a sharp knife, a pair of side-cutters , and a […]

Making ROBOT ARMs is very popular and fun among hobbyists,but it’s not that easy to control a ROBOT ARM. So today we’ll be making a robot arm that can be controlled using just your Android Smartphone or tablet. Good news is, you just need to program the Arduino, the App is already available to download […]

Monitoring an appliance with a microcontroller usually follows a well-worn path of diving inside and finding somewhere in the electrical circuitry that can be connected through some kind of interface to a microcontroller. For his Nespresso pod coffee machine, [Steadman] eschewed tearing into the device, and instead chose to monitor the sound it makes. A commodity […]

We’ve all spent the last year or more under the shadow of the COVID-19 pandemic, and though some of us may have been vaccinated or come through its various waves it remains far from over. One of the hardest-hit parts of the world at the moment is in India, where health services are struggling to […]

There’s no doubt that the RTL-SDR project has made radio hacking more accessible than ever, but there’s only so far you can go with a repurposed TV tuner. Obviously the biggest shortcoming is the fact that you can only listen to signals, and not transmit them. If you’re ready to reach out and touch someone, […]

[Lucas] over at Cranktown City on YouTube has been very busy lately, but despite current appearances, his latest project is not a welder. Rather, he built a very clever gas mixer for filling his homemade CO2 laser tubes, which only looks like a welding machine. (Video, embedded below.) We’ve been following [Lucas] on his journey to build […]

TerraDome is an indoor greenhouse for plants and tropical flowers shaped octagonal dome. It is driven by an Arduino Mega that regulates temperature and lighting through different sensors and an LCD display. It also has doors to the Jurassic Park (or Jurassic World) that opens when the temperature is too high in the greenhouse. Dimensions:50 […]

In this instructable, I will show you how to make an IR remote control system for a model train. You will then be able to control your trains while relaxing on your couch. So, let’s get started! Step 1: Collect All the Stuff! Here is the parts list for electronic components: An Arduino Mega An AF […]

In theory, there’s isn’t much to building a CNC machine. Hook a bit to a motor and move the motor around with some lead screws and stepper motors. Easy. But, of course, the devil is in the details. [DAZ] made a nice-looking and inexpensive rig that probably isn’t the most precise CNC in the world, but it […]

For many of us the passing of the floppy disk is unlamented, but there remains a corps of experimenters for whom the classic removable storage format still holds some fascination. The interface for a floppy drive might have required some complexity back in the days of 8-bit microcomputers, but even for today’s less accomplished microcontrollers […]
