I made this a while back but never shared it so i thought now would be a great time.
So what it is, is a black metal box which is actually a 20 dB pad (for you audiophiles out there) with two adapters to get into the camera. The dB pad already had the XLR connector on both ends so i took off the male side and added a plastic piece with a switch for Bulb mode. I then drilled two hole for the two red buttons to go in. The button in the middle is the focus and the one toward the top is the shutter release. I wanted it to be XLR so that i can extend it easily however far i want (i almost always have access to XLR cable). The adapter from XLR to 1/8" I made and the adapter from 1/8" to 3/32" i had from an old pocket PC. For the final touched i had my brother print (cut) some Pentax stickers. This thing is rock solid and looks good to (if i might say so myself).
Just wanted to share so here are some pictures of the final product with adapters not attached.
