I almost threw them in the bin, thinking they were a bit of stray plastic from the packaging:



Then I took a closer look (not easy at my age):

I managed to solder on the SMD capacitors and resistor:

Plus, they are the devil to solder. You have to clamp them down or they just wander off.

Those look like 0805s.  I just got used to soldering them on, they are not that hard.  I have a method to pre-solder the pads, top with flux, and then use a hot air gun and tweezers to apply these parts as the first step in assembly before larger parts and this works good for me - surface tension pulls them in and makes a nice heel.  I look like a soldering expert under the microscope.  I bought a kit that requires 0402 parts and I just got a cap and a resistor 0402 set so I now have 0805, 0603, and 0402 kits for caps and resistors in common values.  I guess I am set.

I like surface mount parts that have the values coded on.  "103" and "472" is a lot easier to read than a bunch of color bars.

Another oddball item arrived today, a 75 foot Siecor Gold fiber optic cable.  Two strands, tiny stuff.  I got it on one of those 99 cent bids.. mainly because I haven't played with optic fiber and seventy five feet of it for a buck was a no brainer.

So, what exactly can I misuse this for?   smiley-mr-green

Dog leash for the digital age? Strangle your wife with them and take her life insurance money? I have no idea; the fibers are so small that they aren't capable of much light output. I fiddled with some but never had much luck in the blinky light department.

Well the fiber cable may be a nice strong silicone rope smiley

However, I did finally land a good multimeter:

Amprobe AM-1250 True RMS  Multi-Meter (used, tested good)

mouser.com is selling TLC5916IN LED drivers for 94 cents each (in quantities >= 10).  I just picked up two fists-full.

Bought a couple of freetronics mega protoshields and stack header sets . A delight to put to use.
Returned the Duratech soldering station that stopped working after 1 day  smiley-eek-blue and replaced it with the Dick Smith one. Still seems to be working after day #2.
0.7mm solder melts a little quicker, a big help.

Nearly finished this project so bought the Experimenter's kit to have some fun...
