DEER - electronic repeller

Hello,

After assembly and testing I found the forgotten resistor at the reed relay. Pin arduina remained undefined. Fortunately, the relay was connected to Pin 2 which is just next to the ground. Using the 10K SMD resistor 10K size 0402, I fixed it on my finished boards. I also made it into a schematic drawing and board design so I uploaded a new version.

Hello, it is long time from last update.

But there is no better day to publish the program than when this project was featured on the Hackaday blog. Yay!

A lot of people were afraid about of repeating the same sound that animals get used to quickly. But I was counting on it. Even the light blinks randomly. There will be no probelm with a little variation, because the device is installed only a day or two before chopping high grass. Here it is active mainly at night because I do not want to be silent place here. Then at that place the animals do not want to spend the day. Just before chopping, the device is uninstalled and later used elsewhere.

If you find a bug in my program, I'd really like hear about it. So far everything looks fine. I hope it will be readable to others. You can ask in the comments on everything about this project.

Schematic and board is now downloadable.

Board is editable in Eagle free version, dimensions of board are at maximum values for free version. (8x10cm)

Code for Arduino is still under development. Everything looks good, all inputs and outputs seems to be connected right.

New version have regular PCB, it is easier and faster for assembly, and it even looks better.

Custom DC-DC power supply has been replaced with module from China for accessibility for everyone and with easier soldering

I added plastic on pinheaders ends for easier soldering and alignment. It looks better than without that.

Now i need to write programm for new version, it took a while. After that a want publish all files.
