Prototyping is a picky little devil...

OK, Got the datalogging multi meter.

Got the card to hook it up to my array of inputs...
Threaded a ribbon cable to all the little posts... tested all the pins (beep... beep... beep goes the continuity tester!)

Now how to get the Ribbon cable to plug into my breadboard... Thought I had the requisite bits and bobs... But I left behind this at Frys...














because I did not yet see how it could be used to pull the even and the odd numbered pins to opposite sides of the trench in my bread board... You have to give it some rough treatment but...



 Clever! thanks Open Circuits!  Saved the day.

Gizmag is really easy to spoof...(evidently)

Sorry to have dropped away.    Thought I'd hop in with a quick observation:

I like to get the Gizmag emails with the wacky bikes and human powered helicopters etc... But along with comes the likes of this:

ARRG. I'll leave this to my kind readers as an exercise in critical thinking to see what is wrong with this product... (Not a hint exactly but an indication as to why you should sniff about before getting excited is the menu bar at the top: "Home, About Us, Investor") Watch the spinning wheel take people's money just like the ones at the roulette tables (minus the free drinks.)
