Variable current feature can be taken as an optional feature because it’s not an absolute requirement with a power supply, unless the usage is in the range of critical evaluations. The voltage produced should be perfectly regulated. With the advent of chips or ICs like LM317, L200,LM338, ...
If the screen does light up, but you get no picture, then try using a different video input. If it works then, try building a new video amp for the NES. If the screen does not work after trying a different input, check the next paragraph. If the new video amp does not work, your...

Below is a diagram of a voltage waveform after both a smoothing capacitor and a voltage regulator: The second purpose of the LM317 regulator, since it is an adjustable voltage regulator, is to produce variable DC voltage as output. How we vary voltage is by changing the resistor R1and the ...
How fast it does it depends on your device's battery capacity. An iPod Touch has a 1000mAh battery so it should fully charge it in around 2hrs. A 3G iPhone has a 1150mAh battery so it will take slightly longer and a 2G iPhone has a 1400mAh battery, so it will take around 3 hrs...
No, it does not "function through switching". In such a regulator, mosfet is partialy conducting, like a controlled resistor. So it is dropping required amount of voltage. Also as a consequence it is dissipating power: voltage dropped x current. That's why it is not very efficient, especi...
The keyer does also have an internal mini straight key. I find this idea very nice, to avoid extra cables. It is not the most convenient key in the world, but it is there along with the transmitter every time you need it. By using a special panel switch from apem, I was able to ...
https://electronics.stackexchange.com/questions/194435/how-does-this-power-supply-circuit-work Do a Google search for other circuits with 'lab power supply with transistors' or 'regulated power supply with transistors' Here's a site with multiple supplies, at least one is really simple: ...
We already know that a battery converts chemical energy into electrical energy to power our electronic devices. But how exactly does this transformative process work? Again, regardless of what kind of battery you’re working with, the primaryelectrochemical reactionis always the same. ...
can be used as a work bench power supply. It gives 12 volts, 9 volts and 5 volts regulated DC to power prototypes while testing or trouble shooting. It also has a battery back up to continue the work if power fails. Low battery indication is also provided to confirm the battery status...
