Two years ago, I started playing around with cheap 433MHz plugs that can be found almost everywhere. At that time, I got several from different brands, from the well known Chacon Di-O plugs, to the most obscure chinese/no-name ones, and my goal was to reverse engineer as much protocols as possible. I compiled the result into a little tool I called rf-ctrl (now available on my GitHub), and forgot about it. However, this summer, I needed to find a solution to remotely control my electric heaters (not because I was cold obviously, but because I had the time to do it), and thought it was time to dig up rf-ctrl with a bit of polishing (a Web UI called Home-RF).

Few months ago, I completed the build of my RepRap Prusa i3, and decided in the process to add a fan to it.
There are several parts that can benefit from a fan, but since I'm exclusively printing PLA, I was mainly interested in cooling down the print itself. I easily found some nice fan mounts on Thingiverse, but I had some difficulties to find the fan connector of my Sanguinololu 1.3b. And for good reasons, since there is none. Well, not dedicated to a fan at least.

I played a little with the discontinued Rovio from WowWee this week, and found out that the firmware source code has been released some times ago.
Several custom firmwares already exist, but I played with only one so far : Rovio Chat custom firmware. This custom firmware integrates some interesting functionalities (mainly a Network Watchdog), but I wanted to add other features, like turning ON/OFF the blue LEDs.
That's why I just set up a Github repository, importing the original source code (v5.03) with Rovio Chat changes on top of it as a starting point.
So far, I also added the following functionalities :
- Blue LEDs control integrated into the WEB interface
- Incremental camera adjustment control (from Rovio Chat) integrated into the WEB interface
Feel free to check it out !

The Kaossilator Pro is a Dynamic Phrase Synthesizer/Loop recorder from KORG, and I just got mine this week !
However, the version I was able to find for a reasonable price is the Pro
one, which is discontinued... It has been replaced by the Pro + version which
looks almost the same, but offers 50 more programs.
I played a little with it, but soon I wondered if it was possible to upgrade it to the "+" version. After all, both version might share the same hardware (HW) ? It is quite possible since I do not see any real improvement that would justify a entirely new HW revision. Maybe a bigger ROM to fit the new programs ?
