The Nikkor is leftover from before the GF1 came onto the scene and I sold my D80, and the Tokina Twins (11-16 f/2.8 and 18-135 f/2.8) and went M4/3.
Out of some ancient electronics. Will be cannibalized for the capacitors, switches, LEDs and the voltage regulator (bottom left).
A little firefly made of paperclips, at ATtiny13 and an LED. It capacitively senses its body to determine if it is being touched, waking up every ten seconds or so on watchdog to do this.
If it's being touched, it'l start pulsing its LED gently, flashing a random number of times for a random duration each time before going back into a deep sleep.
This photo shows the James Webb Space Telescope's "IEC" all wrapped up in a thermal blanket, and looking like a holiday package at a cleanroom in NASA's Goddard Space Flight Center in Greenbelt, Md.
The Integrated Science Instrument Module (ISIM) Electronics Compartment or "IEC" houses all of the electronics responsible for control, data handling, and telemetry for the Webb telescope's scientific instruments.
The ISIM is one-of-a-kind living framework that provides electrical power, computing resources, cooling capability as well as extreme structural stability to the Webb telescope. It is a state-of-the-art bonded graphite-epoxy composite attached to the backside of Webb’s telescope structure.
The ISIM will contain the four science instruments that will record images and spectra of astronomical objects whose light will be collected by the giant optics of Webb’s telescope element.
The electronics boxes that control each instrument will be mounted in the gift-wrapped IEC and protected from the harsh conditions of space during the mission.

My workbench in all it's glory. Believe it or not, I actually get (got) stuff done here, but I'm much happier with my remodeled bench since I moved.

Semàfor al costat del monument a les víctimes de l'holocaust, a Berlín (Alemanya)

Arguably the most intricate and beautiful of the collection, this piece had an immaculate layout.
This is a large collection of analog tubes.
That package "U105" is really odd. I've never seen anything like that before, and have no idea what it is. U104 is the same type of thing. Given the size of the traces and caps near them, I assume they're power-related, and that's why they have such a huge package. Maybe some sort of regulator?
The clock is assembled in a semi-enclosure made from old cassette tape cases. (Thanks to Denis for this idea.) Yes, it's a bit messy.
We get a lot of stuff from Asia, so it all comes with funny plugs, travelling just adds to the fun.
Left to right, top to bottom we have:
Singapore wall socket, UK

An interesting corner of the main PCB, with RF shielding removed.
Taken with a reversed 50mm prime lens, taped securely to a filter adapter attached to my Canon S70.
My phone died recently. I think the charging circuit quit working, because it would recognize being plugged into power, but the battery never charged. It has since been replaced.
I illuminated this motherboard by shooting a green-geled flash behind it.

a little project for my lab, a mouse that knows at which distance you're from it. We would like to explore if this information could be relevant for the system e.g. to highlight the cursor when you approach your mouse or to tell background operation to interrupt in order to release CPU for interaction...
I use a LDR for the 0 to 4 cm and a Sharp 2D120 IR range finder for 4 to 50 cm. The arduino code here:
// variables for input pin and control LED
int analogInputIR = 3;
int analogInputLDR = 4;
int LEDpin = 12;
// variable to store the value
int value = 0;
int value2 = 0;
// a threshold to decide when the LED turns on
int threshold = 500;
int threshold2 = 300;
void setup(){
// declaration of pin modes
pinMode(analogInputIR, INPUT);
pinMode(analogInputLDR, INPUT);
pinMode(LEDpin, OUTPUT);
// begin sending over serial port
beginSerial(9600);
}
void loop(){
// read the value on analog input
value = analogRead(analogInputIR);
value2 = analogRead(analogInputLDR);
// if value greater than threshold turn on LED
if (value>threshold) {
if (value2>threshold2) {
value = threshold;
}
}
int timez = (1350-(value+value2))/10;
digitalWrite(LEDpin, LOW);
delay(value);
digitalWrite(LEDpin, HIGH);
delay(value);
// print out value over the serial port
printInteger(value+value2);
// and a signal that serves as seperator between two values
printByte(10);
// wait for a bit to not overload the port
delay(10);
}
