Limhes' ramblings

So, last week I ordered a freeDSP kit , assembled it and tried to program it on an Ubuntu machine using the freeUSBi programmer. I couldn't get this to work, so I switched from the freeUSBi programmer to an Arduino micro. Since I now finally got it to work, I'll share my experiences and what I find the easiest way to work with Linux and freeDSP. Hardware needed: A freeDSP classic board + power supply (for testing, I'm using a USB port's 5V supply) An Arduino micro Software needed: Arduino IDE (install the latest version from arduino.cc ) Virtualbox (install the latest version from virtualbox.org ) Install Windows 7 inside Virtualbox Install SigmaStudio inside Windows 7 (from analog.com ) Before getting started, please read the Getting started manual created by the freeDSP people. Most of the information I got from there, with some tweaks to get it working from Ubuntu. Step 1. Create a firmware (hex) file Boot Windows 7 inside Virtualbox, start Si...

This project outlines, without going into too much detail, how to build a small XZ robot based on Arduino Uno and Firgelli miniature linear actuators. The electronics and programming skills needed are low. Mechanical skills required (to build something sturdy) are average to okay, meaning, you have to be able to make something solid ;) (Note: this is an old project, so stuff might be outdated.) What you'll need: Arduino Uno Motor shield: Velleman KA03 (kit) or VMA03 (prebuilt) Any other L298P-based shield ( source code changes needed ) LCD: 20x4 LCD03 from Robot Electronics Any other I 2 C LCD ( source code changes needed ) 12V/2A power supply and a power connector for the Arduino Either a lot of jumper wires or some pcb, pinheaders and wires Two Firgelli linear actuators (12V, linear position feedback, choose stroke and ratio to your needs): L12-P and L16-P Ball bearings, aluminium strips and screws+bolts (Update 2018: I see that Firgelli sells drawer...
