The finish part one


Finishing a guitar is pretty tricky. I suppose if you just want to paint it, then that would be a lot easier, but I wanted to stain mine, then lacquer over the top. This is how I did that.

Firstly, I had to construct some sort of holder for the guitar. I did this with an old broken wood plane I had lying around, which fitted the neck joint nicely. I then made a wooden handle for it and drilled a big hole down it so that I could mount it on a spindle. Badly as this photo turned out, you can see the stand holding the guitar up. It is sitting on a spindle poking out of the top of a big block of wood, held down by a vise. The theory was that I could freely rotate the guitar body this way, and even lift it off the spindle and hold it by the handle.


The first thing I did was to add some water soluble stain. This is just wiped on with a cloth and immediately adds a lot of character to the wood. Here it is after a layer or two of the stain. You can add as many layers as you want. Each one will progressively make the guitar look darker.

Block diagram of AM transmitter and receiver with explanation

Block diagram of AM transmitter and receiver with explanation AM Transmitter : Transmitters that transmit AM signals are known as AM transmitters. These transmitters are used in medium wave (MW) and short wave (SW) frequency bands for AM broadcast. The MW band has frequencies between 550 KHz and 1650 KHz, and the SW band has frequencies ranging from 3 MHz to 30 MHz. The two types of AM transmitters that are used based on their transmitting powers are: ·          High Level ·          Low Level High level transmitters use high level modulation, and low level transmitters use low level modulation. The choice between the two modulation schemes depends on the transmitting power of the AM transmitter. In broadcast transmitters, where the transmitting power may be of the order of kilowatts, high level modulation is employed. In low power transmitters, where only a few watts of transmitting power are required , low...

Using the TLP250 Isolated MOSFET Driver Explanation and Example Circuits

I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well...
