Gadget Techie

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, two pins were used to create an oscillator. One pin outputs a 1Hz signal and the other a 10Hz signal. These outputs can be used independent of the probe to provide a circuit with an oscillation.

First I put it on a breadboard to test it out and make sure everything worked. Once I saw that the LED was blinking at the same rate as the highs of my programmed PIC, I transferred it to a more permanent location.

This was my first permanent circuit (soldered onto a strip board). It was very exciting being able to solder together a very small circuit that is so useful that it sells for quite a bit if you buy a professionally made one. I think I did a very decent soldering job being that it was my first time.
