I clipped my PS onto the circuit directly and at 1.5V it measured
186 mA, then I clipped the same PS clips onto the contacts of the
single AA cell holder and it measured 169 to 170 mA, but veried a bit
when the clips were moved. The single cell battery holder is a Rat
Smack 270-401A with the full length of the chintzy leads on it. I'm
surprised that there was that much diff due to the leads and contacts.
Must be the very thin wire. When I use them, I usually trim the leads
down to an inch or so, so that should help.
I went by RS and bought a couple more 270-412 battery holders.
They're 3 AAA cells, so I can fit one snugly inside the 'Coffee Mints'
tin, as I posted here a week or so ago. Makes a nice little 3 LED
light. Store didn't have them out on the shelves, so I asked the
salesdroid if they had them in stock, and he punched the number up on
the screen, and they had them in the store. So I waited for what
seemed an eternity as he went back in the stockroom and rooted around
in some boxes and finally found them. I got 3, but he had 7 total on
hand. One of these, 3 AAA cells, a switch, 3 LEDs with a 33 ohm
resistor for each LED, and a box to put 'em in make a great little
couple hour project - you can put one together while you're watching
some dumb TV program. Now if I could only find a cheaper source of
'Coffee Mints' tins..
