It needs 2 volts as its threshold however, that only allows a small amount of curent to flow through the transistor. How do I know how much voltage I need to make it fully on. Also, how do I determine what type of resistor to use from the 5V GPIO pin to the gate of the transistor. My other question is what do I need to look at to make sure the diode is strong enough to handle the EMF kickback. The diode I am looking

at is from Jameco with model number 1000 VOLT 1 AMP SILICON RECTIFIER DIODE. VERY IMPORTANT: You connected a transformer directly to 7805 regulator! There is a good chance that such setup will destroy everything to the right side of the transformer. You need a rectifier, a bulk capacitor and capacitors recommended in the 7805`s datasheet for this to work correctly. If the transformer is there to represent wall-wart which outputs DC voltage, than it`s safe, but capacitors small capacitors for 7805 will still be needed for good operation. AndrejaKo Mar 8 `13 at 19:00 @jippie: There are a lot of things to discuss with this circuit, so I`d rather not split the question into lots of pieces. That will make is harder to see the whole picture. Think of this more as a design review question than specifically about the FET and a diode. Olin Lathrop Mar 8 `13 at 19:17
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
