AVR based PCB Drill Machine

admin — Sun, 28 Nov 2010 20:23:20 +0000

This project shows you how to construct a PCB drill machine driven by a master-controller board and three stepper motor driver boards. These four single sided PC boards each contain an Atmega16/32 microcontroller. Communication between the boards is performed using the RS485 protocol with all communication initiated by the master-controller. The PCB drill machine [...]

Home Made PCB

There are many ways to create PCB at home. You can manually laying out the traces with trace transfers (not recommended), photo reproduction (specialized, and expensive), or the use of a laser printer using the toner transfer method. During my experience, creating PCB using the toner transfer method is easiest and low cost. The procedure [...]

Reverse Engineering with Photoshop

If you want to learn Reverse Engineering you can use photoshop as aid tools. For example, This 12-keys keypad failed after years of daily use. No schematic or replacement parts from the original manufacturer. The only option was to replace it with an off-the-shelf telephone-style keyboard.Following the maze of each and every PCB track in [...]
