Open source PCB ruler
Hemal Chevli has designed this open source PCB ruler, that is available at Github: PCB ruler with different foot prints , SMD proto-typing area, tables, various AWG size holes and inches and cm scale.
OSUS – Open source USB Stack test board (Master)
Here’s another cool project by Mats the OSUS Master board: A long while ago I wrote about that I might make a series of boards for easier testing of the open USB stacks. Testing all different version of mcu’s and crystal speeds to make the right #defines and linker maps for the firmwares can be a […]
SquareWear 2.0 — an open source wearable Arduino
SquareWear 2.0, an open source wearable Arduino by Rayshobby: This is SquareWear 2.0, an open-source, wearable Arduino microcontroller board. This version measures 1.7″x1.7″ in size, and has built-in LIR2032 rechargeable Lithium coin battery. It also has a number of integrated components (see below). It is designed to be sewable: you can stich conductive threads through the […]
FarmBot founder Rory Aronson explains Precision Agriculture
Open Electronics posted an interview with Rory Aronson, FarmBot founder: If you have not yet discovered project Farmbot, this interview will be a revelation to you. The project in question, has the ambition to bring digitalization into one of the oldest processes in society, that of agriculture.
M-Stack open source USB stack for PIC microcontrollers
Here is an open source USB stack for PIC microcontrollers and DSPs. It features a dual LGPL and Apache licenses making it suitable for commercial open source projects. So far it only supports the HID device class. A USB device stack is the software necessary to drive the USB device peripheral hardware on a microcontroller […]
Chirp, a plant watering alarm
Miceuz of wemakethings made this Chirp, a soil moisture level sensor based on ATTINY44. When the plant dries out, it starts to chirp reminding you to water the plant: Chirp is a plant watering alarm – as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the […]
PCBmodE: Make your PCB a work of art
Saar of BoldPort developed an open source software for creating artistic and functional printed circuit boards, the PCBmodE: We wanted to create circuit boards that have curvey traces, meandering paths, and multiple soldermask layers, so we developed PCBmodE (say “PCB mode”), an open source Python software that unshackle us from the constraints imposed by traditional PCB […]
Prop Dev Stick REV 0B
Parker Dillmann of Longhorn Engineer posted an update on his Prop Dev Stick project: The Prop Dev Stick is a Parallax Propeller development platform that is designed to just plug into a computer like a USB thumb drive. The old design was just the Propeller MCU with no frills. This time around I added a micro […]
CERN supports KiCad development
Javier Serrano of CERN’s BE-CO-HT section has sent this message to the Developers list to help enhance Kicad: Introducing CERN BE-CO-HT As you know, the BE-CO-HT section at CERN has been contributing to Kicad for some time now. We see this involvement as a key part of our activities regarding Open Source Hardware. We are also […]
4 channel digital TV multiplexer and modulator
Always wanted to run your own TV station? Now you can. Here is a project that lets you encode 4 video and audio channels and broadcasts it on a set radio frequency. The schematic and board files are available for anyone wanting to build their own. The TV transmitter we present today generates a stream […]
TI launches real-time operating system
Texas Instruments has released a free real-time operating system (TI-RTOS) designed for their microcontroller range. They implemented TCP/IP and USB stacks, a FAT file system, and some device drivers. The TI-RTOS’s source code is released under a license that allows you to use their code as long as you use it on their devices and […]
ICDBNavigator Electronic parts organizer
Here’s an open source graphical electronic parts organizer written by WallaceIT, that is available at github. I’d like to share with you a graphical electronic parts organizer written by me in PHP/HTML/Javascript: it’s completely open source (MIT license) and hosted on github. Via the contact form.
Python module for transmitting and receiving infrared signals with an IR Toy
Crleblanc wrote a Python module for transmitting and receiving infrared signals with the IR Toy. It’s tested under Linux, Raspberry Pi, and is expected to work under Windows as well. It’s open source and hosted on the the Python Package Index (PyPI) linked above. I played around with the IR Toy python example and took […]
OpenBeacon – An open source active RFID project
OpenBeacon is a comprehensive open source platform for active RFID applications operating in the license free 2.4GHz ISM band. The project involves base station hardware, as well as active tag hardware. OpenBeacon is based on Open Source software and a very flexible and reprogrammable lowcost Open Source RFmodule. The firmware sources and hardware schematics are […]
An open source electron tube catalog
Here’s your daily retro fix. Electrontubes is an open source database of old school vacuum tubes (electron tubes). It features pinout, footprint, and some basic information about each part. This is an open source electrontube catalogue. Its database contents base type, pin-out and some parameters of components. This database is refreshing continuosly. If you are […]
Great Cow BASIC an open source BASIC IDE for AVRs and PICs
Great Cow BASIC is a set of open source BASIC programming tools for Microchip PIC and Atmel AVR microcontrollers: Great Cow BASIC has been written with three main aims – to remove the need for repetitive assembly commands, to produce efficient code, and to make it easy to take code written for one chip and […]
Arduino task scheduler
Brad shared an Arduino library he wrote schedules when specific functions will be executed. The code is open source and available on github. This library allows you to create a schedule queue of functions to be executed at specified times, on specified intervals. For example, say you’re trying to log some sensor data and update […]
Library for OLED displays using SSD1306 chipset
Library for OLED displays based on the SSD1306 chipset. It was developed for the PIC32 and PIC24 microcontrollers used on the ORbit16 development boards, but it should be easy to port any PIC24/32 project. I’ve uploaded a new library and a new demo for using the OLED display on ORbit16™. The kind of display used […]
Olimex discounts for open source developers
