I am trying to design a little circuit to control a light. It is supposed to be a one-push-button affair, with a long push for something and a short push for something else. One crucial thing is, that ...

This electronic analogue of the push–button switcher allows a short press on one of the control buttons S1–S3 to turn on the selected load Rload1-Rload 3, simultaneously disabling other loads. Unlike ...

Instead of going with a microcontroller he built the circuit around a 555 timer. What he really needed in this case is a flip-flop but lacking a chip for that he went with the 555 because it has ...

After I proposed: PIC reset and I/O on the same push-button? K Wittingham responded: "Why not use a D-Flip Flop Switch connected to clock and via an RC to the Data input. Release switch quickly data ...

This push-button fan switch design includes a timed automatic shut off, connections to the mains, and other minor changes from previous Design Ideas.

South Korean startup Naran launched a crowdfunding campaign on Indiegogo today for a smart button meant to control analog devices ranging from speakers to your crock pot. Called Microbot Push, the ...

Appliance Science: Push button, order stuff. The Amazon Dash Button makes ordering things as simple as pressing a button when you realize you are running low. Appliance Science looks at how it works.
