You may all wonder how much it's expensive to make a prototype for your project.
PCBtrain will cost around 30$ for a prototype. Actually they are doing a good job , and it's
cheaper when we consider their expenditures on the process.
This post is to introduce you to the wiring pencil.
This looks like this. And most importantly , you don't need to buy this. You could make a one using a bobin and

Have fun with complex chips.
