FPGA First steps -3- / Cyclone IV

Update about my FPGA adventures.
I also received my second FPGA experimenting board with a Cyclone IV
The Cyclone II board is a nice development board with a lot of IO pins. To do real experimenting and leaning how to use FPGAs you need to add some additional hardware as the button and led on the board. I did this using a breadboard, some Dupont wires leds resistors and buttons. I also have plans to make a pcbs with some hardware for this board.
The Cyclon IV board has more on board IO. (Displays, buttons, leds, buzzer, dip-switches, video a ps2 keyboard and several pins. Below a photo of my Cyclone IV board in action,
On the left is the USB blaster connected to the board for programming. It is possible to power the FPGA board using the power connector on the topleft. (On the photo below the USB cable of the USB Blaster. I used the alternative method with an USB cable (connector above the 7 segment display).
The software worked when i selected Cyclone IV GX and EP4CE6E22. Also i include a video from my YouTube channel. You see a 4 digit counter. After a few seconds i loaded a new FPGA program / configuration file using the USB Blaster. (the demo program led_test.sof )
