Left Button Microswitch from a Logitech G903 Mouse.
Stopped working correctly after about 13 months much to my dissapointment - now replaced with a new microswitch - no easy task :-(
The basic circuit board from inside a webcam. This photo is from our article explaining how webcams work. Unscrew the lens and the CCD is right behind it (see our other webcam photos for other views of it).

"The street finds its own uses for things." Cellphones and cellphone components were formerly restricted to a high-spending demographic. They transitioned toward mass proletarian usage faster than any electronic tech in history.
Here cellphone gear of dubious provenance is being retailed by a Turinese street-vendor of dubious residential legality. It may seem odd to see the migrant underclass brimming-over with "high" technology, but that's an artifact of a 20th-century model of technological diffusion.
The conceptual twin to this photo would be some "trickle-up" technology, for instance, Wall Street bankers using M-Pesa cellphone payment systems pioneered in Kenya.
How "atemporal" is this image? That perception depends on historical models of class-relations. If class is considered sacrosanct, then this is radically atemporal. Whereas, if "class" is supposedly dissolved in a globalized flat-world, then one would be hard put to notice this spectacle.

Electret condenser microphone.
Working voltage: DC 4-6V
Arduino compatible LM393 sound sensor. This will be used to trigger a Nikon SB600 flash via an opto isolator. The output pin is connected to an interrupt pin on the Arduino. When sound is detected a small red LED on board is momentarily triggered On. The sensitivity of the device is adjusted by turning the blue potentiometer. Arduino sketch for testing

+ yes, my 34yr old amp is needing upgrades :). Almost all electrolytic capacitors are leaking and the trimmer resistors are becoming unreliable. Power switching capacitors are also showing signs of cracking. I also want to change the potentiometer to dual type. Even with all of these issues, the amp still sounds great. With all the upgrades, now the sound is more refined and I thought it already was, before the parts were failing. :)
+ the original amp was using ALPS potentiometer as well but these are 30+ yrs old :), so it really needs to be upgraded.
+ all cameras are tethered via Phase One 8
+ all electronic parts are purchased via RS components

For work, I spent today at an electric motor repair shop where they service huge (and I mean really huge) motors. So for today's post, I shot a tiny motor--one that's only 30mm in diameter, haha.

+ the old capacitors were Nichicon, Nippon Chemi-con and a very few, Rubycon. There are so many to choose from what is available today. I'm currently inclined to use the "audio grade" caps on the audio path but considering the design on this old amp, there are no coupling caps :), mostly decoupling or zener/cap combo whatever. So far, I have tested using the Panasonic FC/FM and Nichicon FG on the audio path and the Nichicon being the best sounding, while the Panasonic are kinda harsh or honky. I will be testing the Elna Silmic II soon to see what it can do, reading from forums who thinks they are better than the Nichicons.
+ for the power supply caps, I will be getting the heavy duty United Chemi-con U32D and U36D capacitors. :D Not specifically for audio but these beasts are rock steady in what they do and if employed for transient audio purposes, it's common sense to use these caps rather than boutique caps that are twice the cost...

This is from our article on how diodes and LEDs work. On the hi-res (not posted here but available for commercial use), you can clearly see the components inside the LED.
