 DIY USB remote shutter release for Nikon D5000 DSLR






"Just a quick email to say thanks very much for your help I used the relays and it worked perfect, the board is working great and I have just received another from you to add to my project. I am using the board to make Christmas lights go to music and here is is the final result, I thought it could be something you might want to use on your site to show one of the possible uses."




We use your USB relays in our product.

We designed a sound level measuring system in combination with labview software.

When a sound level limit is exceeded, the KMtronic USB relay is energised which turns on a signaling device.
