This is a method my friend and I have started using for storing electronics components. We have a bunch of old pill bottles kicking around, so we label them and use them for storage. We've found them most convenient.
When traveling, I go through a rather thorough, yet painful process of figuring out what the heck electronics I should take along. On Saturday, Sara and I will be traveling to Finland and Sweden, so the process begins.
Here is most of what I use today in terms of portable electronics, from the white lens in the upper-left, spinning counter-clockwise:
Canon Lenses
Cameras
Polaroid t833 waterproof
Canon 7D (not shown.. used to take picture)
Phones / portable music / Readers
LG Rumor Touch (Sara's)
HTC Evo 4G
iPod Touch 2Gen
iPpod Touch 4Gen
iPod Nano 1Gen
iPad 2
Kindle 3rd gen WiFi (black)
Kindle 3rd gen WiFi (Pink, Sara's)
Computers
15.4" Dell Studio 1537 (Sara's)
12.1" Dell L attitude D420
Flashes
Canon 430 EX (not shown, bounced off ceiling for photo)
Canon Vixia HF100 Camcorder
Media players / photo dumpers
Vosonic VP8390 160GB
Vosonic VP6230 120GB
GPS
Whew! So traveling, sort-of light, I'll take the Canon 7D, the 24-105, 10-22, 28mm and the 50mm. Only one flash, a 430ex as I don't plan on shooting much with flash. Canon S95 is small and does video, so that's going. Polaroid is not needed as we aren't going in the water. My phone is a necessity (though it's CDMA, WiFi makes it very useful for everything but phone calls). Ipod touches will stay back for Ian (so we can do Facetime w/ the iPad 2, which we will take). Kindles come along as does my laptop. May take both Vosonics for redundant photo copying, camcorder stays as does the nuvi (not taking a car), but Oregon goes for geocaching and general navigation. If you actually made it this far, congrats, you are a nerd.
A power supply, a soldering iron, two crappy but one is at least serviceable multimeters, a hot glue gun, and various other tools.
An unattended radon detection and data logging instrument I built for work. I know... I accidentally installed an under-board SD card slot on the top, so the cards have to be put in upside down. That's embarrassing...
I got 12 IN-14 nixie tubes from Russia sometime in June but haven't had /any/ time to play with them since then. I've finally got around to etching the PCB I designed for a power supply - it goes from 9VDC to 170VDC - and so today was the first test.
I'm delighted to say it worked first time (though I did have to add in a resistor I forgot to include in the design).
I also found out that these nixies have decimal places! I never knew that.
The next step is making a system to control all 12 at once, which will probably need a few of these power supply modules to get enough current flowing. I plan to integrate that with an RTC to show a DDMMYY/HHMMSS clock, but maybe I'll think of something more inventive first.
The IO-103 was the only Heathkit that disappointed me. Long story, but it was a very poor performer, poorly designed. This picture was taken in 1973 or 74.
I designed this circuit board and just sent it out to be manufactured today. Hopefully it will work! There are so many possible errors available...
Vacuum tubes, resistors, diodes, a Tube Screamer guitar pedal, transistors, terminal strips and more!

This Fry's is located in an odd-shaped building, like converted 70s office space. The interior theme is a tropical island paradise. No cafe.
