I recently shelled out around $900 and bought myself a Prusa i3 3D printer kit for rapid prototyping. Unfortunately, I spent quite some time getting the 'calibration' working. The RepRap wiki was very helpful in helping to calibrate. However, I was quite lucky and the supplier where I got my kit from actually provided me with … Continue reading 3D printing adventures →

It plays a song of your choice (or a random song) from a USB drive plugged into the side of the box. Personally, I prefer the Final Fantasy victory fanfares.

A few people in the community have come up with some interesting designs for a home … Continue reading Idea for TI-Nspire serial adapter →

Update: For a much more in-depth analysis of the problem, head over to Naked Security where Paul Ducklin explains the bug in much more detail. Gizmodo recently published an article about OS X Mountain Lion crashing when the text File:/// is typed into TextEdit, Spotlight, Mail or some other OS X apps. It's also reported … Continue reading File:/// crash in Mountain Lion workaround →

Status updates are now available from the wiki entry on Hackspire.

I've just begun a port of Linux to the TI-Nspire CX and I'm happy to say I have a minimal kernel booting successfully on the calculator! Here's the UART bootlog and you can see we actually make it to userland without crashing! The minimal port has support for the interrupt controller and the timer. UART … Continue reading Linux Kernel port to TI-Nspire CX →
