As we all knew that the currently worldwide economy has been moved in the downward position and most of the countries all around the globe have been seriously affected by this economy crisis.
It’s getting hard and harder to earn our living and that’s why you should learn how to save as much of money as you can! However, some of you may think that it’s easier to be said than done…
Well, guessed what! Would you believe if you could develop the cheapest dual trace scope with a cost less than $8 per unit? It seems unbelievable but this is the fact!
For your information, this submini USB dual trace scope is based on Atmel Tiny45 CPU and it’s a homemade PCB. It has two analog inputs and can supply 5V onto the four pins header on the right. Beside that, one of the inputs can be scaled down with the trim pot.
Instead of the low development cost, this dual trace scope’s size is about a credit card and it’s a very cute and compact component as well! As a result, it can be easily plug into a project breadboard and you no need any power supply here.
