Variable Linear Voltage Regulator: Part 2

Now that I have a little more time on my hands, I have decided to transfer the voltage regulator circuit that I previously posted about onto a strip board.
I am still trying to work out the best layout of the components but here are a couple of pics of what I have so far. In [...]


TV Remote Jammer

This was a fun project. I got the idea for it at a website (I cannot remember which at the moment). The idea is simple: You make a circuit that sends out an IR (infrared) signal to the TV with the same frequency at which the TV remote operates, essentially ”masking” or “jamming” the signal coming from the [...]


Logic Probe

Once again, I decided to build my own equipment instead of buying it for a lot more. This time it’s a logic probe. It uses a 12F PIC to detect when a signal is high (1) or low (0). Being that it has a lot of pins and only one is needed for the probe, [...]


Learning to use PICs

Throughout my undergraduate career I focused entirely on analog circuits. Now that I started this hobby, there was no avoiding digital and to be honest, I felt horrible that I had a bachelor’s degree in Electrical Engineering and I knew very little about the digital side of things. Because of this I set out to [...]


Variable Linear Voltage Regulator

This little circuit is a money saver! Before making it, I was looking for a varibale power supply for my projects and the prices were usually well above $100. It wasn’t until I went to the electro-tech-online.com forums and talked to some people there that I realized that I could just make my own power [...]


Stereo Audio Amplifier

The very first circuit that I ever made on my own was a stereo audio amplifier. I chose to make this circuit out of necessity. At the internship I was in, the computer seemed to not amplify the audio coming out of it and my speakers did not have an amplifier either and so the [...]


Hello World!

Well hello fellow viewers. This is my very first post on this blog. I am still unsure of the aim of this blog but for now I think I will focus on my hobby: electronics.
I recently got into this hobby and so far have invested well over $300 on it. In my opinion that is very [...]
