What better way to announce the availability of the Portenta Vision Shield LoRa than at The Things Conference 2021 – a global showcase for all the top-notch LoRaWAN products and services. The LoRa® module option of the Portenta Vision Shield is specifically designed for edge ML applications, enabling low-power, long distance communication over LoRa® wireless

Kids have wonderful imaginations, and to help students at a primary school have a super time, creator “palladin” was asked to construct a console for them to use. The device features a variety of lights and sci-fi additions, including glowing “reactor” tubes that diffuse light using hair gel and a “memory bank” that emits flashing patterns for

Christopher Getschmann wanted a wall-sized map of the world. He soon realized, however, that it’s tough to actually buy such a map that’s both beautiful and detailed enough to satisfy his cartographic tastes. While many would simply move on to the next “thing,” Getschmann instead took things into his own hands, and built a pen

Whether granting access to public transit or restricting unauthorized personnel in buildings, NFC card readers can be extremely useful. Although most might not consider how they work – and simply happy getting through a turnstile – there’s a lot going on behind the scenes. In his video, Daniel Raines shows off a pair of prototype

While it’s hard to beat analog instruments for instantaneous automotive feedback, Finnish electrical engineering student Jussi Ristiniemi also wanted a digital speed readout on his 2002 Audi TT. His particular model normally uses the car’s controller area network (CAN) to transmit the radio station or CD track to the uppermost section of the digital display.

If you live in a house with stairs and have to traipse up and down at night, it’s best to have some sort of light that guides you. Although a cell phone can work just fine, or you could likely activate bright overhead lighting, creator MagicManu devised an automatic and progressive solution to illuminate his

If you’ve ever wanted to wind balls of yarn, then look no further than this automated machine from Mr Innovative. The YouTuber’s DIY device is powered by an Arduino Nano and an A4988 stepper driver, spinning up a round conglomeration of yarn via a NEMA17 motor and a timing belt. The ball is wound on

‘Raspberry and chips,’ not something you’d like to eat but in the world of silicon it’s actually a great combination. Eben Upton recently shared with us Raspberry Pi’s exciting vision for a revolutionary product that they were working on: a microcontroller, the RP2040, based on Raspberry Pi silicon. The news was both disruptive and exciting

The Coanda effect, as you may or may not know, is what causes flowing air to follow a convex surface. In his latest video, James Bruton shows how the concept can used as a sort of inverted ping pong ball waterfall or staircase. His 3D-printed rig pushes balls up from one fan stage to another,

Creator DuctTapeMechanic loves sports and electronics, so for a recent project he decided to combine his two passions by hacking a speed bag to keep track of his punches. As shown in the video below, the first step was to get it physically set up, modding an old metal bed frame into a support structure.
