ChainringGen – making a chainring with open source software
Rich Olson writes: ChainringGen is an OpenSCAD script I wrote that can generate a bike chainring with any specifications you like. You can download ChainringGen here. You can control parameters like bolt-circle-diameter (BCD), number of bolt holes, number of teeth and other stuff. I primarily created ChainringGen because I thought designing / milling my own […]
openSAM: a 3D-printed open source camera stabilizer
OpenSAM by OHM – a 3D Printed Camera Stabilizer: Welcome to OpenSAM, our 3Dprinted self-built three Axis stabilizer. It is handheld and the entire mechanical construct is built using 3D printed parts. Brushless motors ensure the camera is stable and they can be controlled using a joystick. The design is developed by three engineering students […]
The CANable: a small USB to CAN adapter
Ethan of Protofusion writes: The CANable is a hardware clone of Eric Evenchick’s CANtact project, an open-hardware USB to CAN adapter compatible with socketcan. I took his design and reworked the hardware to be a bit more suitable for my personal needs, with a screw terminal instead of a DB9 connector and a much smaller PCB. […]
Developing a parallel detector for the Open Source CT 2
Peter of TricorderProject writes: I’ve been thinking about tomographic imaging a lot lately in between nursing sore fingers from learning how to hand-wind electromagnetic coils for my attempt at a small prepolarized coded-field MRI, and I thought I’d take a moment to share some progress. The open source computed tomography (CT) scanner that I put […]

TinyK20 open source ARM debug/universal board
Erich has posted an update on his open source ARM debug/universal board project. We wrote about it previously: After the proof of concept phase (see “Proof of Concept: Open Source ARM SWD Debug and General Purpose Board“), the first prototypes are ready I had the first prototypes of the board we have produced internally in my […]
Wavewatch, a soundcard oscilloscope and waveform generator
D4p0up shared his open source soundcard oscilloscope in the project log forum: Here is a tool that might help some of you in your DIY activities : WaveWatch, a soundcard oscilloscope 100% made with Processing. I’ve just released the 1.3 version, making it a very credible, user friendly and totally open source alternative to existing soundcard […]
Arduboy – card sized gaming
The final Arduboy, an Arduino gaming and learning project, came out yesterday. Kevin has been in Shenzhen arranging manufacturing for the last few months. He’s also been a staple at the neighborhood BBQ place and Hacker Camp after parties, some of us even got access to pre-release dev-kits. Of all the project builds I’ve witnessed […]
Proof of concept: Open source ARM SWD debug and general purpose board
Erich of MCUonEclipse writes: The Freescale FRDM boards are using a Kinetis K20 based circuit (see “OpenSDA on the Freedom KL25Z Board“): However, that firmware is not open: the K20 is secured and protected, so the firmware cannot be changed. Newer Freescale FRDM boards like FRDM-K22F2 and FRDM-K64F do have an open source bootloader and debug […]
