This circuit emulates the functionality of the classic 555-Timer IC. It was designed using open-source tools and was taped-out in the Skywater 130nm CMOS process through TinyTapeout on April 19th 2024 ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Publishing house Scholastic wrote the epilogue on its ownership of 555-557 Broadway with the sale of the SoHo building to Empire State Realty Trust (ESRT). Scholastic made a strong profit in the $386 ...

Abstract: This paper reports an industry standard monolithic 555-timer circuit designed and fabricated in the in-house silicon carbide (SiC) low-voltage bipolar technology. This paper demonstrates the ...

Meet Bille, the name given to the world's first monostable tetrahedron—a four-faced object that will always land on the same side, no matter its starting position. This feat of geometry and ...

All the tech we rely on, from cars to smartphones, was engineered using physics. You don’t need to know the science to use these things. But a well-rounded human should understand at least some of the ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...
