Replace Poly-61 battery with Lithium battery

Just a quick update. I made a small board out of strip board and placed a holder for the coin type Lithium batteries that are so common (CR2032). I put a schottky diode in series with it to prevent the reverse charge current.

I'll just put a photo here and then if you're interested you can read the rest of the boring details :)

Built data entry knob stuff

Well, not much to write about actually. I have just built the design I made earlier but not yet mounted it or even tested it yet.

I made the strip board design using a program called Loch Master 3.0 available from http://www.abacom-online.de/uk/html/lochmaster.html for €39.90. A very good tool for planning your strip board projects!

Here's what I came up with using the program:

Another Matrix!

Impulse buy?
Ok, maybe I didn't need this one but .. Come on.. The guy that was selling it lived in the same city as me and he just wanted 150 Euro for it. I had to buy it...

Roland Juno 2 (rackmod) a.k.a. Plexijuno

Plexijuno
It's a Juno 2 but without keyboard, and it's mounted on a piece of plexi glass.
It's the Plexijuno!

Good progress. Prototype done.

I got myself a programmer, some PICs and started to learn. I had to do the compulsory "blinking LED" but after that I continued to see if I could do what I wanted.
