Once upon a time, if you wanted to generate some waveforms, you needed to buy an expensive off-the-shelf function generator or whip up a big pile of analog electronics. Not so today, when you can grab a fast microcontroller off the shelf and have it squirt out whatever fancy waves you might desire. That’s just what […]

When we first saw [Maarten Tromp]’s article about a “momentary latching switch” for guitar effects pedals, we have to admit to being a bit confused. When it comes to push-button switches, “momentary” and “latching” seem to be at odds with each other, with different mechanisms inside the switch to turn one into the other. What gives?

It started with someone asking [James Bruton] about using a Möbius strip as a tank tread. He wasn’t sure what the point would be, but he was willing to make one and see what happened. Turns out it works reasonably well! The main design challenge was creating a tread system that would allow for the required

The Internet of Things (IoT) landscape is a dynamic and rapidly evolving field, with the Arduino Cloud platform standing as a key player. Recently, this platform has undergone a significant upgrade, a testament to Arduino’s commitment to fostering community-driven innovation. This upgrade, largely influenced by user feedback, has transformed the platform into a more intuitive, powerful, and user-friendly tool, making IoT
Arduino Cloud for IoT and more enhanced further from user feedback Continue Reading
Stream decks are cool and all, but they are essentially expensive, albeit sorta cool-looking macro pads. So why not try to make your own? You don’t necessarily have to start from scratch. It all started when [dj_doughy] found an extremely clicky num pad in a recycle pile. It was so clicky, in fact, that even though
NUM PAD REBORN AS STREAM DECK Continue Reading
What’s the worst part about packaging up a whole lot of the same basic thing? It might just be applying the various warning stickers to the outside of the shipping box. Luckily, [Mr Innovative] has built an open-source automatic sticker dispenser that does the peeling for you, while advancing the roll one at a time quite satisfyingly.

DIY e-bikes are often easy to spot. If they’re not built out of something insane like an old washing machine motor, the more subtle kits that are generally used still stand out when compared to a non-assisted bike. The motors tend to be hub- or mid-drive systems with visible wires leading to a bulky battery,

As fun as claw games are, the jaws are always disappointingly weak, and you usually end up with bupkis. What if the jaws were completely within your control? That’s the idea behind [Upside Down Labs]’ muscle-controlled servo claw game. While electromyography (EMG) is great for identifying neuro-muscular abnormalities and allows for amazing prosthetic limbs to work,
SERVO CLAW GAME PUTS YOUR MUSCLES TO THE TEST Continue Reading
Real flowers do it, and even the Beatles did it. [Robo Hub] now has a plastic sunflower that tracks the sun using, of course, an Arduino. It may not qualify as a real robot, but it does mimic a real sunflower. The electronics aren’t earth-shattering, of course. An Arduino, a light sensor, and a servo motor are

Have you ever imagined commanding a device solely with hand motions? Envision your phone wirelessly sending emojis to friends representing your hand gestures in real-time. This vision is now a reality! Using ST’s innovative multi-zone Time-of-Flight sensors, camera-free gesture recognition is possible. AI algorithms running on the low-power STM32 microcontroller identify hand poses with minimal
