Jman 31's v2.5 Megadrum (will update as I go)

Postby jman 31 » Sat Feb 07, 2009 5:50 pm

Well it's finally started. I am going with Sythex's v2.5. I know it would probably be easier to order his kit, but I really enjoy doing all the steps myself. I am looking forward to the challenge.

I have some 8x12 sheets of copper clad board that I cut to size for the PCB. I use a very sharp utility knife and score both sides and then stick it in a vice. Putting constant pressure on it one way and then the other it will make a nice clean break and is a lot less messy than cutting it with a dremel or other cutting device.

So I got a decent toner transfer despite my new iron. It is a good one that was just getting to hot. I have done several projects, but this one was a little more detailed so the transfer needed to be a little better than my previous ones. I found that a lower temp setting with lots of pressure was my best bet. I tried a couple of different papers and had the best success with a matte style paper. I had to do some very minor touch ups with a Sharpie marking pen.

I also decided to make a bubbler for etching this project and I'm glad I did. I used 2 parts hydrogen Peroxide and 1 part muratic acid as an etching solution. In the past it's taken a couple of hours for my projects to etch in a glass dish, but with the bubbler it took less than 5 minutes. Good thing I was paying attention! :shock:

After the etching I went over the traces with a continuity tester because I was pretty sure a couple of the traces were touching and sure enough they were. I took a very sharp utility knife and ran it in between the traces to cut whatever copper was still touching. Worked like a charm.

Here is a picture of my board ready to be drilled and populated. I will update it as I go. Monday I will be ordering parts from Mouser.com using Gastric's definitive list.

Here's something I did for myself. I don't know if it will help anyone else. The colors are random and don't signify anything but the different traces. I thought it would make it easier when I was testing the traces to track each one.

I have started keeping the record of MY MEGADRUM BUILD on MY DIY SITE. You will have to register to view, but it might be worth it. I have several DIY drum projects that I have done and may help someone along the way. Feel free to comment, post your ideas or anything else that is DIY related if you want.

After several frustrating tries at the 2.5, I purchased the 2.8.
Much much easier bro, good luck though :)

Here is a pic of my v2.5 up and running. Proof that it can be done! Now I have to decide what case I want to use.

Thanks guys. I don't know that I will ever use it, but it was a fun project. I'm not a drummer, so I don't even know where to begin with it. I still need to make the midi wires and an on/off switch, but basically I guess I'm done. I wish there were more great projects like this on the web.
