Arduino 24V Digital Input Hat
Fernandez May 10,2026
An Arduino Uno industrial input shield designed to connect 24V industrial automation signals directly to Arduino-based projects. It converts 24VDC digital inputs from PLCs, proximity sensors, limit switches, push buttons, and other industrial sensors into safe Arduino-compatible 5V logic levels. This makes it easy to use an Arduino Uno for industrial monitoring, automation prototyping, machine testing, control panels, data logging, and educational PLC training systems without unsafe wiring or bu...

PathFinder
Arnov sharma May 07,2026
Greetings Fellow Travellers, and welcome back.This is PathFinder, a DIY digital map device powered by the UNIHIKER M10, designed to help you find your way.I go on rides in mountain areas near my hometown, and there, I frequently get no signal in some areas. Relying completely on Google Maps is a no-no; sometimes, due to data issues, maps are not loaded completely, and this can be a nightmare if you are stranded.This could all be sorted if we had a physical map and some navigation skills. I ...

PS5 Controller
Copeland May 05,2026
Hi everybody  I worked on this PS5 controller for a month. Please cut me some slack I am only 14 so still learning. Anyways, here is the direction for assembling. First let me list all the components and then we will get into how to assemble it. Note - you need a USB C cable to connect the PS5 to the computer.PS5 Replacement Joystick: https://amzn.to/4vIzbDGVertical Pushbutton: PCB SMT Parts Library & Component Sourcing Now for these they are pretty rare so you can't...

Home Internet Router Rebooter
Hallen May 02,2026
Our broadband Internet router will occasionally drop off the Internet. This is easily solved by power cycling the router. This isn't really a big deal when we're at home but it has happened a few times now when we're away on holiday. Again, not usually a problem but we now have a few, ahem, "smart" plugs for turning lights on/off and some RING cameras - these all stop working.This device is quite simple.It utilises an ESP32-C3-Zero development board to connect to WiFi and periodically ping well-...

DIY Shortwave Propagation Monitor - Measure Ionosphere Conditions
Pavleski Apr 30,2026
 Shortwave Propagation is the way radio waves in the 3 to 30 MHz range travel from point A to point B, using the ionosphere as a mirror. The ionosphere is a layer of the atmosphere full of charged particles (ions). The quality of the signal depends on how "dense" this layer is.  This is affected by several factors such as Solar activity (the most important factor), time of day (day or night), seasons, and others. In this project I will present you a very simple way to measure the ...

Drone Detection
Bandini Apr 27,2026
Drone Detection SystemAs part of a symposium presentation, I decided to build several drone detection prototypes using different approaches: image-based detection, audio, and radio frequency.For image-based detection, my initial idea was to train a machine learning model and deploy it on a dedicated Linux board with a camera array. Instead, I chose a simpler and more engaging approach that attendees could easily replicate—even without much maker experience.SenseCAP WatcherSenseCAP Watcher is an ...

Electronic Fish Feeder
silicioslab Apr 24,2026
Never forget to feed your fish again and with the right amount, at the right time.Regular feeding is one of the most important factors for the health and growth of fish, whether in home aquariums or larger breeding systems. However, maintaining this consistency manually is not always practical, especially in busy routines or during periods of absence.With this in mind, this project presents an automatic feeder developed with 3D printing, designed to be simple, efficient, and accessible. Using a ...
