GinoBot programmable robot teaches you coding engineering and more

GinoBot programmable robot teaches you coding, engineering and more

The development team at Engino have created a new compact educational robot in the form of the aptly named GinoBot, enabling users to learn more about programming, engineering, 3D printing and more. “GinoBot integrates science, technology, engineering, and mathematics into the latest programmable robot”. The small GinoBot robot includes third-party hardware support for the likes of […]

ECG PROJECT WITH ALL THE MESSY SAFETY DETAILS

ECG PROJECT WITH ALL THE MESSY SAFETY DETAILS

We’ve seen a number of heart rate monitoring projects on Hackaday, but [Peter’s] electrocardiography (ECG) Instructable really caught out attention. If you’ve followed Hackaday for any period of time, you’re probably already somewhat familiar with the hardware needed to record the ECG. First, you need a high input impedance instrumentation amplifier to pick up the millivolt

A 50 CNC

A $50 CNC

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

CLEVER GAS MIXER GETS JUST THE RIGHT BLEND FOR HOMEBREW LASER TUBES

CLEVER GAS MIXER GETS JUST THE RIGHT BLEND FOR HOMEBREW LASER TUBES

[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

INDIAN MAKERS RESPOND TO THE COVID 19 PANDEMIC BY PRODUCING OXYGEN CONCENTRATORS

INDIAN MAKERS RESPOND TO THE COVID-19 PANDEMIC BY PRODUCING OXYGEN CONCENTRATORS

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

ARDUINO MKR MAKES NESPRESSO MONITORING EASY

ARDUINO MKR MAKES NESPRESSO MONITORING EASY

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

BUILD YOUR OWN BLUETOOTH NOTIFICATION TICKER

BUILD YOUR OWN BLUETOOTH NOTIFICATION TICKER

Stock tickers were telegraph-based machines from the 19th century, and quickly fell by the wayside with the advent of computer replacements from the 1960s onwards. However, there’s something charming about small machines that deliver us paper strips of information – as demonstrated by this notification ticker from [DIYprojects] (Russian language, Google Translate link). The heart of the build
