I started working on a new project the other night. It took most of the night but the proof of concept looks promising. Take a look at the video below, follow the link to flickr to see it in HD.
Full source code is available for this thing on thingiverse . OpenSCAD has proven to be an easy to use and flexible tool, but at times I'm left scratching my head to figure out ways around its limitations. In this case I had two squares with rounded corners, their sizes and the corner radius for both squares are configurable. Now I wanted a square tube to join these two pieces together. My hope was that I could get it close enough with some fancy parameters piped into the OpenSCAD linear_extrude function. It seemed possible since there are some pretty fancy parameters regarding rotations and twists. After checking out the documentation it didn't look like there was anything that would be close. For this project I found a module by Felipe C. da S. Sanches to create squares with rounded corners . I'm sure there are many like it, but this was the first one I found and it worked as advertised. So made a little module using this which wraps around a rectangle for ...
For the past 18 months I've been tinkering with a terminal application that serves as an Algorand node frontend. I had a number of requirements in mind when choosing the technology: a full screen terminal application, works over ssh, extensible to allow it to evolve with different utilities and views of the system over time, be programmed with the Go programming language. In the past I've created these sorts of programs with bash, but it's not fun to manage terminal control characters and deal with re-drawing with bash. Using bash has always led my applications to be simplistic, typically never getting beyond simple spinners and progress bars. I knew about ncurses, but didn't want to lose the portability of bash -- some of these scripts were even POSIX compliant, and honestly I just didn't want to deal with low level interfaces and C bindings. Enter bubbletea . The team at Charm has built the tools I didn't even know I needed. There is an impressive array of d...
If this helped you, please consider downloading my FREE iPhone app " Hydrate Yourself "and leaving a review. There are a whole bunch of tutorials to create a Navigation Controller inside a TabBarController with XCode3. But there are a number of small changes in XCode4 which can trip up someone not familiar with them. So this guide is essentially an updated version of those other guides, designed to create the same simple demo using the new tool. 1. Create a new Project We are going to start with a Tab Bar Application, so go ahead and create a new project as usual. I'm calling mine Navigation Tab Bar. 2. Select the Tab Bar Click MainWindow.xib and you should see the integrated Interface Builder. On the left is a section called Objects, select the Tab Bar Controller. 3. Add the Navigation Controller On the right side of your screen click the Utilities box. This is new in XCode4 and should look familiar if you've been...
