Post by thread:Best Breadboard/Prototype system

I strongly suggest the solderless breadboard for "playing around" to see what works. It's incredibly easy to change a wire or six if you get it wrong the first time. I have been known to go straight to PCB, however. I do this if the chips are too large or fine-pitch to put on a breadboard Many of my circuits use 64 or 80 pin surface mount uP's and RAM's, etc that make it really hard to breadboard. In this case I generally review my circuit several times over a week or two and have one or two others look at it as well before laying it out and getting a PCB cut. Breadboards are great for small circuits, low frequency analog (up to around 50 MHz depending on your noise margins), and especially for trying out new ideas that aren't sure to work. don
