FW: [motm] The MOTM philosophy - Was: supplying schematics

-----Original Message----- Another reason: may people think a schematic contains all necessary info to actually build something. WRONG! ... The inclusion of schematics for our products is to help the kit builder both build and learn but they are not designed to allow duplication of the product...... There is "magic" in what we do and like good magicians everywhere, we don't let go of all the secrets...... ---Reply---- I have no problem with any of this thinking. I don't see any reason why you should be obligated to provide DIY "pirates" with every bit of info, including PCB layouts, parts sources, etc., to recreate the project from scratch. (After an item was completely discontinued, it might be nice for this info to survive as historical documentation, of course.) I think all anyone is asking for is a basic schematic. You know... "I just plugged in my module and a puff of smoke came out of it... let's see what's going on in the area of the power supply input to the board..." Just some help with troubleshooting, and some general appreciation of what's going on in the circuit. "Oh, so THAT's how you sum three incoming control voltages! So I could easily add a fourth input by sticking another jack and resistor in there..." I don't think anyone would argue that manufacturers are honor-bound to supply complete info to help pirates steal their circuits. And, personally, I think only an insane person would try to build an MOTM/Blacet/etc circuit from scratch when, for a modest sum, a full parts kit with professionally-etched PCB is available! But I guess there are some real masochists out there! There's no way you're going to *really* get away any cheaper---not at that quality level---unless you place absolutely no value on your own time. Someone with enough skill to etch a really good PCB for cheaper ought to have more respect for the whole process (and as I say, something better to do with their time). If I order an MOTM EG kit, it arrives, and a couple of hours later it's built and running. For what it costs to get a 'real' one (in time and $$$), why on earth would I try to make a sloppy knock-off on breadboard?
