Usually, when you build a clock, you use a clock chip such as a DS1302 but in this example, Kenneth Finnegan shows us how to make a “pure” TTL clock without using any microcontrollers or timer chips.

I think this could be a great way to learn about circuits in general plus there might be some times where TTL chips can come in handy and lower your overall production costs.

Circuit DIY – How to Prototype Printed Circuit Board using Laser Cutter!

For those of you lucky enough to own a laser cutter in your home, you might want to learn how to prototype your own, custom printed circuit boards.  Not only custom boards will allow your project to have maximum flexibility, you will benefit from having a “printed” circuit board instead of using a breadboard or something of less stable sort.

I am going to walk you through the process of prototyping a Printed Circuit Board using a laser cutter and supplies from your local Radioshack and hardware store. This is a process I have perfected after several prototypes I

Circuit DIY – How to Make PCB with an EAGLE schematic!

Here’s a great tutorial showing you how to make a PCB with an eagle schematic.  I am sure most of your PCB experts know how to do this but for those of you dummies who can’t, this is invaluable free lessons.

In this instructable, we’ll make a printed circuit board from that schematic

I guess I should say that we’ll make a PCB DESIGN ; making the physical board is a different task, and there are a lot of tutorials on the net (and even some instructables) on making the board after you have the design.
