Component Organizer source code released

A while back we posted about an app, Component Organizer, that helps you organize datasheets, and app notes connected to various parts you may be interested in. Yesterday Msr let us know that he has released the source code. You can download it at github. He also added a tutorial to help contributors get started. […]

Dual-tone multi-frequency signal generator and detector

Robots wrote a open source Dual-Tone Multi-Frequency signal generator and detector for his STM32 based development board. The code is available via github. DTMF generator is based on AVR314 appnote, and the detector is my practice in signal processing using “Goertzel algorithm”. Everything is written for integer/fixedpoint arithmetics. (no floats at all)… Generator generates signal […]

Visualize and analyzing serial data in real time

SerialChart is an open source Windows app for charting incoming data over the serial port in real time. The incoming data should be in CSV format, with each point on a separate line. The first value in the data stream should be the horizontal coordinate, a comma, then the vertical coordinates and a line feed. […]

HOW-TO: Open Source USB stack for PIC microcontrollers

This guide shows how to configure and customize the latest version of the JTR-Honken open source USB stack for PIC microcontrollers. The demo will run on most USB-enabled projects from Dangerous Prototypes. Be sure to check the wiki for the latest documentation and downloads. Many PIC microcontrollers have USB hardware. We use some of these […]

#Twatch clock grabs time from network

David turned the Twitter streaming #Twatch into clock that pull time from a SNTP network server. The coding is done, and it’s available for download. David also included documentation in the download package, as well as on his blog. The zip file has complete source, firmware, and a PowerShell module for using the LCD emulation. […]

#Twatch turned into a SNTP clock

David modified his #Twatch firmware to display time collected from a custom GPS-NTP  server. He provided full documentation for his modifications, as well as the source code. While the #twatch is not the ideal display I envisioned, it was an excellent first try on my part. I had to make some simplifications due to the lack […]

MCHCK – a small ARM Cortex M3 development board

Small form factor board, with a STM32L151 ARM Cortex M3 for around 5 dollars. This is the target of the MCHCK development board. The board was designed to be cheap enough so that you can develop a project with it, and not have to re-purpose it for the next project, but get a new one […]

Open source solar data acquisition system PCBs

Arup got some PCBs made by Seeed of the open-source data acquisition system he designed. The system uses solar panels, and rechargeable batteries for power. An ATmega32 microcontroller reads, and stores data onto a SD flash card. Data ca also be viewed via a character LCD. Via the forum.

SenseMote wireless sensors and actuators via Arduino

SenseMote is an alternative firmware for the Ciseco XRF CC1110 module. It enables you to build wireless sensors and actuators via an Arduino-like sketch language. I believe that the gateway, the “sensehub”, has a lower BOM cost than Nanode or any other open source wireless gateways and has more flexibility due to the CC1100-style radio. […]

USB development board with a custom scriptable language

SigLab is an open source USB development board that takes commands from a small program that runs Python-like scripts. The hardware is basically a PIC18F2550 breakout board, but the firmware makes it easy to get started using the familiar desktop scripting language. SigLab is a combination of open hardware and FOSS (free and open source […]

512K SRAM memory module with 13 pin interface

An open source 512K SRAM memory module for adding extra ram to your project: I have designed a very simple PCB module that allows access to 512KBytes of Static RAM.  It is compatible with any microcontroller with at least 13 free digital IO pins and the ability to run from a 3.3v or 5v supply. […]

Bus Pirate mentioned in Bruce Perens open hardware lecture

Bruce Perens, the author of the Open Source Definition, and co-founder of the Open Source Initiative,  held a lecture on the topic of “The State Of Open Source, And Introducing Open Hardware”. He mentions the Bus Pirate and our CPLD breakouts as positive examples of open hardware. The Gadget Factory’s Papilio One FPGA development board […]

KTechlab IDE: Open source software for microcontroller simulation

KTechlab is an open source microcontroller simulation and development application. It features circuit simulation, firmware development, a C compiler, and a flash programmer. So far it supports only old PIC16F84 uCs. KTechLab is a an IDE for microcontrollers and electronics. It supports circuit simulation, program development for microcontrollers and simulating the programmed microcontroller together with its […]

Open source SMT pick and place machine

Ever get tired of fiddling with tiny surface mount components using tweezers and a magnifying glass? The OpenPnP project that aims to be your sweet relief: OpenPnP is a project to create the plans, prototype and software for a completely Open Source SMT pick and place machine that anyone can afford. I believe that with […]

7400 Competition: An ‘open source’ open source competition

The open 7400 logic competition is a collaborative, crowd sourced, open source competition. We started with a few prizes, but we crowd sourced our way to 20 sponsors and $1000s of dollars of swag. Judging guidelines, categories, and artwork were contributed by the community. Rules and materials are all open source, use then to get […]

PixelController: Universal OpenSource light control solution

Pix­el­Con­troller is a real time video/VJ gen­er­a­tor and mixer with open source soft­ware developed by Michael. It generates images on a color matrix, as seen above on his PixelInvader panels. It supports many standards like Art-Net, Mini-DMX, LPD6803, and Seeedstudio’s Rain­bow­duino. Via the contact form.

Editorial: Our friend Microchip and open source

Microchip jumped into open source last spring with the chipKIT Arduino-compatible development boards and open compiler/IDE. They wanted to tap the existing tutorials, enthusiasm, and customer base of Arduino community, and they were going to play nice with open source. A review of the chipKIT situation today is disappointing. The compiler still replies on closed […]
