Hi all.
I recently purchased a (obviously) second hand CRO oscilloscope.
It worked fine for a couple of days, I was just getting used to it.
Then one day, I left it on for 10 mins or so with both traces active on screen.
A while later, I heard this high frequency hiss, so I switched it off.
The...
Hi everybody,
I am not only new here but have little to no clue about electrics/electronics, but a question, where I am hoping to get some ideas/answers.
I have purchased a winch enabling me to pull our boat on a trailer in and out of the water on a ramp. The winch requires 12V and I would like...
Hey guys,
This is my first post and I am happy to have found this website. I am currently working on a project using a PCB and jumper wires to make a 48v Phantom Power supply to be used with multiple condenser microphones. To make a long story short, I found a "mostly" detailed post on another...
The wall power is rated at 50 to 60 cycles per second. I want to feed a circuit with that energy (50 - 60 Hertz) and obtain a higher frequency output, pure sinusoidal wave. Preferably, it can be tuned from around 100 hertz to 30 kilohertz.
The output wattage must be at least 300 watt.
I have a toroid transformer where the input is 230 VAC and it has 2 output each one rated at 40 VAC.
Can I feed the 40VAC part with 230VAC and get >1 Kvolt output?
