Send collected data to windows computer through USB
There are many different ways you can achieve this. The simplest IMO would be to use a UART-to-USB IC (such as an FT232) and simply transmit the data over UART. You can use the +...

Production Programmer
Is the added cost of the Xeltek really worth it? IMO it's a question of connecting and disconnecting Alank2's programmer in 16 times vs connecting and disconnecting the 16...

Destroying the firmware if fuse bits are reset
I'm not sure if this would work, but you could set the programming pins to outputs so they're driven high or low, thus disabling the programmer from connecting to it - why might...

Communicating to 2 SPI Slaves with USART & SPI ports on Atmega16U2
For completeness, it's worth mentioning that you don't always necessarily need a separate SS pin for every slave you wish to connect to your SPI - you can use just one SS line and...

Trying to avoid JTAG conflict with ATMEGA6450
How about not using the JTAG for production releases, opting for a bootloader instead, and if you're using a UART anywhere use that for debugging (i.e printf() debugging)?
