Bus Pirate 3.5c is the next project we converted to a 3D model. This time we upgraded the rendering with Maxwell’s render plugin for SketchUp. The plugin is free for resolutions of up to 800×600. First select the materials (plastic, aluminum, lacquer) for your object from the preloaded library, then start the render. It creates […]

3D Model: CPLD development boards
This week we converted two of our CPLD development boards to SketchUp 3D models. These boards were designed to help with CPLD development. Both XC9572XL and XC2C64A CoolRunner II CPLDs are available. The models will be published in the Dangerous Prototypes 3D warehouse collection. They are also uploaded to our SVN. You can find them […]
3D Model: Web Platform 1.1a
We started building 3D models of our projects. The first design to be converted into the 3D realm is the Web Platform, our tiny web server based on a 16bit PIC mircocontroller. This was made possible by using the import/export script EagleUp. The models will be published in the Dangerous Prototypes 3D warehouse collection. They […]
Dangerous Prototypes 3D project models
We’ve started to build SketchUp 3D models of our projects. To automate the process we’re using the EagleUp export/import script. It builds a 3D model of the PCB and arranges models of components onto the board. Sounds simple right? It is pretty easy, but you still have to find or build models for all the […]
Gerber preview software and usage summary
We asked what things you check before sending gerbers to the board house, and what your favorite gerber viewer is. Here is a compilation of your responses: Problems with the footprint, the solder pad is sometimes buried by mask. Drills outside board or flipped. CAM didn’t export expected silkscreen layers. Evaluating not only whether a […]
App note: nRF24L01+ 2.4GHz wireless transceiver
The nRF24L01+ ICs are 2.4GHz transceivers that only need a few external parts. They’re controlled by a simple SPI protocol, and two extra pins. The IRQ pin signals when data is available and can be used to wake a microconroller with an interrupt. The CE pin is an input activates/deactivates the transceiver. 126 channels are […]
