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.
Released in the early 1980's, The Amigo 620 is a very strange model. Unlike the other 600 series, the Amigo 620 lacked a built-in electronic flash. Instead it used a flash bar socket like the earlier SX-70 series. A socket on its flip-up hood required special “Flash 600” flashbars. Strangely though, it did include the added sliding close-up lens, allowing for photos as close as 2 feet, which was a fairly rare feature in the 80's model Polaroid 600s. It also featured a super cool creamy tan body.
The Amigo has a single-element 116mm plastic lens, fixed focus of 4 feet (2 feet with close-up lens), electronic shutter, and exposure correction dial.
This model includes a built in close up lens, which allows the focus down to around 60cm when engaged.
So why does my camera have a built in flash then? Well, I will explain...
This camera is a bit of a Frankenstein's Monster, and is dear to me as it is the first 600 type camera that I ever modified and repaired. I loved the look of the Amigo 620, however I really wanted an electronic flash, so I set out to make my own. Using the internal electronics from a Polaroid Sun 600 LMS, I dis-assembled both cameras and created what was possibly the world's first tan Polaroid 600 with an electronic flash!
Arguably the most intricate and beautiful of the collection, this piece had an immaculate layout.
This is a large collection of analog tubes.

This is the finished Eagle with the old electronics and the 22AWG cable. (you can see my Talon on the background. Even though they look kinda similar they are worlds apart internally)
A +/- 6V & +/- 12V 42A power supply from the 70's or so. Beautiful wiring, except for the raw 240v adjacent to low signal voltage through the connector plugging into the machine.
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?
Not anything dangerous...Nor was it shot at 12:05 AM. It's just I've been monkeying with this particular (almost) antique alarm clock for the past few days, and found out its original alarm off button doesn't work. So, like any good hacker does, every time they want that alarm to shut off (besides snooze) they open it up and short the appropriate wires. Turns out, shorting just anything often works to reset it, and shorting the upper red wire to pin 4 on the chip shuts the alarm off for the day.
Former RCA Technical Institute at Cherry Hill Industrial Park in Cherry Hill NJ, opened in the early 1960s. There were also RCA Institutes in New York City and Los Angeles, and they had home training courses. In the mid 1970s this became Sylvania Technical School. It was later Lyons Institute, I took a course here in Electronics and Digital Technology in 1982-83. It is now JDR Shoe Warehouse store.
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);
}
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.
Here are the buttons. I'd actually prefer a softer cap on those switches, but it's good to see that these aren't just cheap tactile switches, but higher quality switches with more throw. These should last a long time and take a lot of abuse.
