It's always interesting and useful to read about projects in great detail - from concept to finished product, and all the considerations that need to be made along the way. One example of this is a chronograph project by Instructables member mofoya, who takes us on a journey of building an AVR-based device to measure the time taken for an object to move between two points.
Originally designed to measure the speed of a model rocket, the chronograph can be used for all sorts of moving things - and can be set to display speed in various units through a series of DIP switches. Furthermore the processing of developing the code in C, designing the hardware and circuit through to PCB stage is documented in detail, making this project an interesting read at least.
If you find yourself working with AVR-based projects or uploading firmware to various projects - then you'll need our USBasp - the USB in-circuit programmer for Atmel AVR controllers. Based on the original design by Thomas Fischel, it's fully compatible with the Arduino IDE and all three major operating systems, using the USBasp is a cinch.
You can select 3.3V or 5V target voltages, supply power to your project via theUSBasp and even update the firmware on board yourself. Furthermore we've included the ICSP cable and microUSB cable to it's ready to use out of the box.
