TI unveils ULC1001 ultrasonic lens cleaning chip for self-cleaning cameras - CNX Software
Texas Instruments (TI) has introduced the ULC1001 digital signal processor (DSP) ultrasonic lens cleaning (ULC) technology designed – when combined with DRV2901 piezo transducer driver – for self-cleaning camera systems to quickly detect and remove dirt, ice, and water using microscopic vibrations.
Cameras used in the automotive, industrial, robotics, and smart farming industries may require cleaning from time to time and that usually means manual cleaning leading to potential downtime, higher maintenance cost, and so on. It could also be done through mechanical parts but that adds further complexity to the system, so instead, Texas Instruments ULC1001 and DRV2901 combo enables cameras to rapidly self-clear contaminants using vibrations to eliminate debris.

Restore the mechanical sounds to your Apple II diskette emulator #VintageComputing #AppleII #Floppy
Do you miss the iconic sounds of mechanical click-clacking from original Apple II floppy drives? Does the familiar rattling of a boot floppy bring a smile to your face? Noisy Disk uses a mechanical relay to create authentic-sounding mechanical stepping sounds for disk head movements for a Floppy Emu disk emulator’s virtual 5.25 inch floppy disk.

pycasso: How to build a picture frame to show you random AI art every day
After a quick configuration, we have a battery-powered unit that doesn’t need to be plugged in to power except to recharge. It powers up at a predefined recurring time, and then turns itself off again. No cables, someone can hang it on the wall if they like. It has 3 switches on it and the first switch by default boots the pi unit, which is perfect for cycling the image ad-hoc. The PiJuice class in python has a lot of features which I’m still exploring. We currently use the battery level information to draw a little square in the corner of the screen when the battery is low.

1940s Philco radio sings again with new Raspberry Pi heart
Almost every single GPIO pin on Raspberry Pi 4 is used in this project. A 7.9-inch capacitive touch LCD screen provides an oscilloscope-style display showing the sound waves on the front of the radio.

I fixed my beautiful little Commodore Plus/4!
I’m glad these machines are getting more attention and interest today, to the point where people are even investing time on creating videos and even replacement components. These are special machines that have a unique place in 8-bit computer history, even if Commodore bungled their marketing and pricing at the time. If the C128 is my favourite second-hand 8-bit computer of all time, the Plus/4 and C16 aren’t that far behind.
