load_switch_panel_4x2.kicad_pcb_gerber
Apr 11,2026
The load_switch module allows to control the the power supply of MCU periperals such as sensors, actors, GPS modules etc. in power sensitive applications.The core component is an ultra low leakage and quiescent current slew rate controlled high side switch with reverse blocking capability. The switch is a low on resistance p-channel MOSFET that supports continuous current up to 1.4 A. The operating voltage range is from 1.5 V to 5.5 V.This module allows connection via soldering half-hole edge pa...

DIY GSM GPS Location Tracker with Arduino
Joseph Apr 09,2026
Project OverviewThis project demonstrates how to build a simple and reliable location tracking system using an Arduino and a GSM module. The device retrieves GPS coordinates and sends them directly to your mobile phone via SMS. It’s ideal for basic tracking applications like vehicle monitoring, asset tracking, or personal safety.How It WorksThe system uses a GSM module (SIM800) to communicate over the cellular network. When triggered, it fetches location data (latitude and longitude) and sends i...

STEAM MACHINE Iota
Arnov sharma Apr 06,2026
Greetings everyone, and welcome back!Meet my version of the new Steam Machine.The build was inspired by the new Steam Machine that was supposed to launch, but got delayed due to the RAM crisis. I was actually planning to get one, but since I couldn’t, I decided to take matters into my own hands and build one from scratch.I’ve worked on a few Steam Machine–style projects using SBCs, so I already had a solid starting point.https://www.hackster.io/Arnov_Sharma_makes/bazzite-on-lattepanda-mu-setting...

Shaker Table Control PCB
Seiler Apr 06,2026
This shaker table was developed for the primary school for testing the stability of spaghetti/marshmellow towers, which the children build themself. The idea was that they learn about stable forms for structures like triangles and then a tower building competition was held. In the end every tower has to withstand different load cases generated by the shaker table to simulate an erthquake.I wanted to make this project available for everyone, so that also other schools could build this shaker tabl...

esp32 Midi Prodessor
Fischer Apr 06,2026
It’s an esp32 with 2 independent Midi IN- and 2 independent Midi OUTputs and a USB-host adapter. Incoming MIDI data (notes, CCs, MIDI Clock) can be routed and modulated. Every output can be modulated independently. As of firmware version 0.98 these are the available features per output:Route every input to every outputMerge MIDI data per outputModulate velocity:velocity passthru (no modulation)set to 63set to 100set to 127randomizerandomize around 100 (95..105)Modulate a note’s MIDI channel:pass...

Build a Long-Range Wireless Appliance Control System
Jain Apr 03,2026
Controlling electrical devices over long distances is often challenging, especially when internet connectivity is unreliable or unavailable. This project demonstrates a practical solution using LoRa communication, enabling you to operate appliances like lights and fans from a smartphone—even across large distances—without relying on Wi-Fi or complex networking.By combining LoRa with Bluetooth Low Energy (BLE) and a microcontroller such as Arduino Nano, this system creates a bridge between short-...

Programmable RGB Thermometer
Adhikari Mar 31,2026
Summer has been relentless this year. My passion for Bitcoin mining took a major hit due to the immense heat from my miners and the electricity costs required to keep them cool and running. There were times when the miners overheated so badly that I had to shut them down "manually" to prevent a fire hazard.To automate the shutdown and restart process and to enable remote temperature monitoring, I built an RGB thermometer with its own web interface that can control home appliances based on temper...

Bare Femto Development Board
Real Space Pro Mar 24,2026
I was thinking to myself....."what if I could have a cheap, tiny microcontroller that was open source?"And That's When it Struck me, The CH32V003 Series!These Boards Need Nothing But A Power Capacitor!So I studied them THOROUGHLY and Came Up with this design!it has 17 GPIO pins!and is only 7mm by 7mm !note: needs a WCH link E for programing through the swio pin
