Prototype board for MCU modules and fits inside 100x68mm waterproof housing
GALOPAGO Jul 02,2022
PROTOTYPE BOARD FOR MCU MODULES AND FITS INSIDE 100x68mm WATERPROOF HOUSINGThis board can host MCU modules up to 20 pin per row in a double row configuration. The minimum separation between rows is 2.54 mm and the maximum separation between rows is 27.94 mm, so most common types of MCU modules are supported. The board is designed to fit inside a generic 100x68mm (advertized as Sonoff switch) waterproof enclosure.Find a complete project using this PCB: https://galopago.github.io/english/lora-sate...

Wearable Arduino Power Gripper
Mech-Dickel Robotics Jun 29,2022
ConceptWhile I was designing this mad gadget, I had in my mind a desire to create something with a really crazy mechanical sci-fi look that I could attach to my arm, that could grab objects and maybe crush them. :)MechanicsIn the picture below you can see all the mechanical parts I created for this project using only manual techniques, with simple tools and affordable materials.The main materials used in this project were PVC pipes and connections, high-impact polystyrene sheets and aluminum she...

Arduino Uno Mini LE Cube
Wiguna Jun 28,2022
I thought this would be a quick weekend circuit sculpture project. However, I underestimated how small the Arduino Uno Mini LE is.Glad I designed a PCB instead of bending the wires to plug into the Uno directly.Designing the soldering jig was a lot of fun. At this scale, a jig is essential.Wiring is straightforward. No extra chips were used to drive the cube.The Arduino drives sixteen Anodes (vertical pillars) via 1K resistors. Four common Cathodes (horizontal layers) chose which layer is active...

Real-time Food Quality Prediction
AlexMiller112 Jun 26,2022
With each passing year, the issue of food waste becomes more acute for the environment. A recent Food Waste Index Report by the United Nations Environment Program (UNEP) showed that, on average, consumers waste almost a billion tons of food per year (or 17 percent of all food purchased): https://www.unep.org/resources/report/unep-food-waste-index-report-2021The fact that people produce more food than they consume has significant negative consequences. For example, an estimated 8-10% of glob...

TinyML Monitoring Air Quality on 8-bit Microcontroller
AlexMiller112 Jun 26,2022
StoryI’d like to share my experiment on how to easily create your own tiny machine learning model and run inferences on a microcontroller to detect the concentration of various gases. I will illustrate the whole process with my example of detecting the concentration of benzene (С6H6(GT)) based on the concentration of other recorded compounds.To my mind, such simple solutions may contribute to improving the air pollution problem which now causes serious concerns. In fact, the World Health Organiz...

Detecting Unstable Electrical Grid with TinyML
AlexMiller112 Jun 26,2022
IntroductionElectricity is the heart of modern social and economic development. More and more countries strive to transfer to sustainable energy systems, which is quite a challenging process, as it causes increasingly unstable power generation and grid overloads. The unstable electrical grid can endanger people's lives and the safety of their property. This means that power systems should undergo timely monitoring and optimization, which AI and machine learning can easily handle.In fact, artific...

Tiny ML for Big Hearts on an 8-bit Microcontroller
AlexMiller112 Jun 26,2022
StoryIn the course of the pandemic, the interest in creating more innovative medical devices has run high, as recent years showed how unpredictable the situation in healthcare can be. Never before have we faced such an acute need for masks, ventilators, oxygen cylinders, and other must-have devices to conquer the pandemic.All this has become a trigger to develop devices that can work autonomously for a long time, without access to the internet or cloud, just on batteries with ultra-low power con...
