Camera sensor.. this is just a few millimeters across.
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.
Here you can see the D40x sensor with its IR blocking filter removed. Without this filter, and without an IR passing filter, the D40x now records both IR and Visible light.
On my birthday in 1983 I got my first camera. With this camera, an Agfa Optima Sensor, I made my first train pictures.
Dreams do come true with the Vtech InnoTab Learning Game Cartridge - Disney Princess. Your little one can enjoy three interactive learning activities that use the color touch screen or tilt sensor to play while learning about colors, counting, and comparisons.

I will be using this camera in week 71 of my 52 film cameras in 52 weeks project:

The first year is documented in this book:
Sensors fitted with rubber washers and contour rings, you will need to select the correct contour rings to fit the countour of the bumper when fitting the sensors
The Agfamatic 100 is a viewfinder camera for Pak-Film 126 cassettes. It has an Agfa Colorstar lens with fixed focus and fixed aperture. Two shutter speeds are selectable with the ring around the lens barrel, the scale showing a cloud and a sun symbol. The camera has a single stroke advance lever that advances the film, cocks the Parator shutter and turns the flash cube holder on which magicubes can be fired as flash. On the axis of the advance lever is the red "sensor", the shutter release button hidden under a round piece of red foil. A little black plastic button side on the side unlocks the back door for opening the camera. The back door has a window for making visible the film cassette's exposure counter. The camera has an optical bright frame viewfinder of reverse Galilean type
This is a very simple digital sound sensor (Arduino Sound Sensor Module for Sensor Shield, SKU 74446) from Goodluckbuy. It’s either triggered because there’s a sound loud enough or not. The sound level threshold can be set by adjusting the pot on the PCB and the red surface mounted LED can visually show you when the device is being triggered. Much like the light sensor an op-amp is used (LM393).
The only down side is I would have liked the choice of either a digital or an analogue value much like the light sensor and it’s switch.
This light sensor works reasonably well. Goodluckbuy list it as “Electronic Brick Light Sensor Brick Module” (SKU: 75283). That’s right brick is in there twice.
From what I could find I think made by Itead. The A-D switch lets you pick the type of output from the sensor. An analogue voltage or digital high/low. The switch point for digital is adjustable via the pot and the board uses an LM358 op-amp.
Programming and working out how to apply an analogue input value to automatically adjust an output brightness value for my series of 7-segment displays proved annoying and I had little success. I believe a lot more trial and error would be needed to make this and other displays adjust with the brightness of the room. Or perhaps I’m just a bit crap.

Sensor part of the FreeStyle Libre blood glucose monitoring system. This dedicated sensor is integrated on the main board inside the monitoring system. 42 photos are stacked using Zerene Stacker. The full width of the photo is approx. 15mm.
Camera: Nikon D850, ISO 64. Lens: AF Micro-Nikkor 60mm f/2.8D @ f/11 + 68mm Kenko extension tubes. Manual controlled microrail @ step-size 200um. Natural light.
Agfa Optima Sensor (~1982)
Solitar lens 1:2,8/40mm
Paratronic shutter 1/30-1/1000
Zone focus

The advance lever double functions as rewind lever, after the rewind button is pressed.
This camera was made in Portugal
At one time, I would take my digital cameras to a technician to clean my sensors. When the cost became prohibitive, I started cleaning my own.
Here are two Youtube videos that I found helpful :
QRD1114 Infra red sensors embedded in milliput, to get the infrared emitter diode and infrared phototransistor separated enough to have the fit either side of the sleepers on z-scale track.
It's been awhile since I've been able to work on any fun projects but this weekend I dug an old Raspberry Pi out of the junk box. Flashed the OS. Adding an ADC hat and non-invasive current sensor to monitor 240v power usage by the Bitcoin miners
First results of the new line sensor TSL1401CL 128 pixels at 400 dpi resolution. This signal show the piek level of the green laser on a white surface reflection. The signal is here is saturated due to the white surface.The intergration time is 47.5 us and the scan time is 70 usec. Even on a black surface the signal is about 1V. The readout of the analog signals are done by 2 ADC convertors type ADS7885 here at 32 MHz clock. The line sensor is more sensive compared to the previous version TSL202R at 200 dpi.
For the optic see:
All soldered together, working, and sealed up in a nice box. Now just to write software to do something interesting with it.
Agfamatic Sensor 100, Germany, 1971.
What must be the best, most minimalist case ever designed for a camera.

A map of the pentax autofocus sensors. Contrary to what the indications in the viewfinder, these sensors are not points but are T and L shaped on the sides and a cross in the middle. Only the 9 points in the middle are cross sensors.
Une carte des zone d'autofocus. Contrairement à ce que le viseur laisse supposer les "points" d'autofocus ne sont pas des points mais des L et T sur les bords et une croix au milieux. Seuls les 9 points du milieu sont de type "croisé" (ils détectent un contraste aussi bien vertical qu'horizontal).
Got sensor cleaning brushes from visible dust (reviewed here). got rid of most of the crap (compare top and bottom) although in some cases it just added different crap or moved existing crap around. cleaned it about 10 times instead of the recommended 2x. unfortunately one of the brushes ships in a plastic envelope which has adhesive placed such that it's hard to remove the brush without contacting it with the adhesive. I think that's what added the smear in the upper left part of the frame. Fortunately the company offers a liquid cleaning product to get rid of smears created by the brush-poorly designed envelope product.
