I this somthing that anybody else has encountered. thanks Nick Below is a link to a picture of my work in progress http://stridershouse.ddns.net/index.php/s/YhgkNXjbH3dmfn1

thanks very much. The electronics are working perfectly now. I found out that I had an earth loop somewhere. it works I am waiting for my blaster bits now. thanks for all of your help.

I do have one question. what do i do with the main legs on the led drivers? Can i just un-solder them or cut them off, or use them to mount them? What is the general opinion?

Hi there. I am using the WT5001M02-28P v1.00 I have stripped it down now to the basic test code. Now i am getting sound but the startup sound is looping? I am new to c coding so any help would be appreciated. thanks

Hi there. I have all of the board layed out on breadboard. it is powering up and working. How ever, i am getting no sound. yes. It could be a faulty sound board or amp, but i just wanted to check to see if the files on the sd card have to be in a folder or somthing, I see from the images that you have 2 arduino files on the card. Where do they come from. Any help would be greatly appreciated. thanks
