The gizmos to start my generator remotely by PC: timzim.blogspot.com/2008/10/remote-generator-start.html
Circuit that I used to measure the flash duration of the microsecond flash. Saturation of the photodiode must be avoided, it helps to bounce the flash off of a closeby white wall.
Don't you just love my handwriting?
A BPX61 photodiode is used which does have the peak sensitivity well into the IR characteristic of silicon detectors. The 50ohm terminator is not required if the scope has a 50-ohm input impedance setting (mine does not). Also important to make sure that your choice of resistor is still primarily resistive at frequency so no wire wound resistors!
Why is it naked you ask? Well, tonight when I went to shoot some shots of the delicious dessert, none of the back buttons worked. Thankfully taking it apart and putting it back together seemed to fix it. So the camera isn't broken after all. Yay! :) (Taken using Michael's most excellent Nikon D70.
Here you see all stops along the way, and the various modes of transportation.
Traveling from left to right:
[ol]
[*] to Tateyama station (立山駅) by train
[*] to Bijodaira (美女平) by funicular
[*] to Murodō (室堂) by Bus
[*] to Daikanbō (大観峰) by trolley bus through the mountain
[*] to Kurobedaira (黒部平) by ropeway
[*] to Kurobeko (黒部湖) by funicular though the mountain
[*] to Kurobe Dam (黒部ダム) by foot
[*] to Ōgisawa (扇沢) by trolley bus through the mountain, and finally
[*] to Shinano-Ōmachi (信濃大町) by bus.

You can make the trip in either direction.

This is a pile I picked up for a total price of $70.00 at an estate sale in San Francisco. The guy was apparently an electronics tech for hospitals and schools.
Cell phone charger can't do data. So I opened up the connector to see which pins the 5 VDC was connected to.
When I received this and plugged it in, the first thing that happened was a huge flame shot out of it...
Today I took a closer look and found the component that caught fire, bought a new one at Kjell&Co and replaced it. It works! Sounds great!
During the dis-assembly process aluminum is removed from electronics such as computers, monitors and televisions, then recycled. This aluminum will go to a large metals sorting/chipping/baling facility to be sent for remanufacturing.

The switch alternates the two LEDs. It's a neat little board, although the 7pin header was added by me to make it a bit more extendable.
