Happened to me :-). Simpler than the "big boys" (8051, 68HC11, etc.) very capable and easy to do (IMO). For things like timers, I like the parts count :-) one. Once you get things prototyped you can (with the BASIC Compiler I have for Pics) just compile your stuff into a Pic (not quite that simple, but not difficult, just takes some time and money :-). The BASIC Stamps are pretty capable all in all, if you can program in BASIC then you probably won't have too much transition time and if you don't BASIC is about as simple as it gets for programming (other issues aside). > What's the best way to get up to speed?

I've heard many times over the years that RS parts are floor sweepings and out-of-spec parts at OUTRAGEOUS prices. The other side of that coin is that they are there and VERY convenient for small parts orders (assuming they have what you need/can use) they may still be somewhat cheaper than shipping... That said we move on :). The place to start looking into these is http://www.parallaxinc.com there is LOTs of good information to be had there. I personally do not like the BS2 and for a lot of things IMO it is overkill. Same with their latest release - forget what it is called, but it is *QUICK*. :-) you might develop an interest in robotics, you never know <grin>. You can get started for the download time for the manuals and examples and the wear and tear on your printer and the price of the stamp itself. If you can figure out how to make a board to put it on (USE A SOCKET) and build the interface cable, you can get started cheap. The starter kit is around $100 to $150, I forget, but I am sure it is on the web site. Check it out and read the manual and examples (PDF files you can download) to get some idea if you really want to do this to yourself :-). > This is very exciting Vikki, congratulations!

I'm setting a new target current of 2ma per your comments and others. Also the person I am making it for says it is STRONG and tastes "bad". It doesn't seem so tp me :-). I have not a clue what PPM the solution is, but it tastes like CS :-). > I'm not sure, but perhaps you're running into the "starved electrode" > effect described in a past post by Bob Lee > I'm inserting a copy....I'm sure it will interest you anyway... > >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> > [ ... ] Thank you very much, I've seen this referenced before. I looked that over and initially I have the "deer in the headlights" look :-). I'm going to have to study that for a bit to make sense out of it. Maybe it has just been a long day :-). If you have questions on the Stamp, let me know, I'll try to help. I've done several projects with them so I may know a little bit :-).
