This is the inside of a Decca transistor radio 1960s design. For the electronics enthusiasts, its clear to see how very different this looks compared to a modern day device. Not a silicon chip in sight, in fact the transistors are the older germanium type. The battery is newer of course, this radio belongs to my mother in law and is still used.
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.

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!
I wonder what I was doing on 30th March 1996? Not the most sensible place for a sticker, as this transformer get's pretty hot when the PSU is working hard!
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!
Vacuum tubes, resistors, diodes, a Tube Screamer guitar pedal, transistors, terminal strips and more!

Cell phone charger can't do data. So I opened up the connector to see which pins the 5 VDC was connected to.
Range box inards. Way more stuff than the Launch Controller. The charge pump circuit along with the high side fet and low side fets. LCD screen is to the right.
