AI Thread Summary
To design a variable timed circuit cut-off activated by a push switch, a 555 timer circuit can be utilized. The circuit should be configured to operate within a timing range of 1-3 seconds for motor activation. Instead of using a relay, a power MOSFET should be employed to control the motor. Adjusting the size of the timing capacitor will help achieve the desired ON time. This setup is suitable for voltage ranges of 8.4 to 9.6 volts.

im really drawing a blank on this one...

been a while since i done timers and its late!

im totally lost i need help designing a varible timed circuit cut off,
but it needs to be activated by a push to activate switch.

the timing on this literally needs to be 1-2 possibly even 3 seconds, to operate a motor,
and needs to be able to work time after time. its going to be running 8.4 to 9.6v

any help or pointing me in the right direction would really help

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
