Just came back from the market. Bought two 1400mAh Li-poly cells, SMD IC's and connectors etc. It's 5 PM now and I haven't slept since yesterday afternoon. I was completely taken in by this stuff I'm trying to build. Don't worry, I don't usually stay up like this. The local market for electronics is a tall building, whose entire east sector of the 3rd floor. There're over a hundred stores inside. Some are organized pretty much the same way as Glenwood sales, and others come in all different appearances. Down south in Shenzhen, China, there's the largest electronic market in China. Situated around **broken link removed**, about a dozen buildings stand there each with thousands of stores inside. I've been there twice, and I wish I could bring the whole district back here with me.
I've never played with ARM either, though I am in need of better processing power. The O-scope project sounds familiar to me. It's an interesting and creative idea and is worth a try. I realized another interesting idea in my thesis design, kind of same thoughts like you - turnning simple theories into reality. I'll attach a picture of the design below. There was a thread with a video of it that I had uploaded a long time ago, unfortunately the video is a dead link now.
I bought an Altera CPLD quite a long time ago, but since I never had time building a downloader, it's been put aside forever. I may start playing that stuff when I'm really in the mood of building a download cable. And I'd also like to try Xilinix FPGA's coz it might be the best choice for a multi-channel PWM generator.
