The battery, slightly filed down so the current probe can slide into place. This slot helps to keep it from touching more than one contact, too.]]> Gallery Administrator photo Sat, 12 Jan 2008 16:34:02 -0800 http://ecloud.org/gallery/main.php?g2_itemId=259 http://ecloud.org/gallery/main.php?g2_itemId=259
Close-up view of the current probe itself: two strips of very thin single-sided PCB, epoxied back-to-back, with wires soldered on. Each strip has a thickness of 0.3mm and the whole thing is 0.7mm thick.]]> Gallery Administrator photo Sat, 12 Jan 2008 15:24:12 -0800 http://ecloud.org/gallery/main.php?g2_itemId=256 http://ecloud.org/gallery/main.php?g2_itemId=256
"current probe" inserted between + battery contact and the corresponding contact on the phone]]> Gallery Administrator photo Sat, 12 Jan 2008 15:24:12 -0800 http://ecloud.org/gallery/main.php?g2_itemId=253 http://ecloud.org/gallery/main.php?g2_itemId=253
Overview of setup for measuring Neo1973 battery current. The Fluke multimeter measures the resistance of this current probe and the meter (on the 500mA scale) as 0.6 ohms, and it seems to be pretty accurate. If I use the Fluke as the current meter, when the Fluke auto-ranges into a low current range, its resistance is about 40 ohms, and the phone cannot power on. Also the analog meter does a little averaging so it's easier to read - not so "jumpy".]]> Gallery Administrator photo Thu, 17 Jan 2008 22:45:56 -0800 http://ecloud.org/gallery/main.php?g2_itemId=201 http://ecloud.org/gallery/main.php?g2_itemId=201
