I'm curious if anyone has actually successfully constructed a V2.5 board from scratch? Buying all components, constructing the board, constructing ICSP programming cables, programming ICs, and ending up with a fully functional and usable MegaDrum? Browsing the various posts I only see users buying the V2.7 kit. And recently me and Japi and Bobnickelson building a V2.5 board, though neither of us has met with success yet as far as I know.

Note I'm not knocking this project, the V2.5 board, or anything. I'm just fishing for someone confirming this thing actually works and is buildable using the V2.5 board. Show me ONE PERSON that's done it successfully so I have hope that someday mine will be as well.

I successfully built the 2.5 unit the way you say, buying components in my local shops, etching the board and drilling it, and so on.

<- Here you can see my finished unit.

I was surprised that the hardware was perfectly built at first try. I had some firmware issues but I managed to solve them, so now I have a very good working unit made from scratch

And you programmed the IC yourself using ISCP cables? I'm having no luck as you can see in this thread:

I programmed a bootloader (with clock selector). I had some difficulties. I had to program it several times till I got a well-programmed firmware...

I confirm here (you already knew hehe) that my v2.5 works.

Here's what I tried so far

lcd works (backlit worked after changing the 470 ohm + resistor for a 33 ohm one)
icsp header for atmega works
32 pads connector works
trimpot works
buttons works

Didn't try yet:

midi connector, i won't ever use it
led, i will connect it to the case
icsp for usb, already flashed so no use

Thanks Japi !!
