I'm going to be putting in an order to web-tronics (mainly for the sodium persulfate for etching). I noticed that with a $50 order they will give you a DMM for free ($20 value). I'm in need of a new one, my Sears dmm is falling apart :? It says it "Measures transistor hFE" what does this mean?
With my order right now, sodium persulfate, heatshrink tubing, and 8x10 single sided copper board, I'm up to $27. I could just buy the DMM, but that would put me up to $50 anyways, so I'm looking for some suggestions on what else to order (this is the point of the message, I underlined it so it didnt get confused with my other questions). I'm looking for general stuff that is commonly needed, I already have plenty of caps and resistors that I salvaged from old circuit boards. Any ideas please let me know.
Also, I'm getting a 1kg package of the sodium persulfate crystals. Anyone know the mixture ratio to water? and approx. how many square inches I can etch with it?
