![]() To go really neat, instead of just fixing the wires together, wire a small 'push to make' switch between the wires. Switch on live view and plug the dongle back in and live view will stay on until you switch the camera off or pull the dongle out again. ![]() Take the wire 'dongle' out of the camera. Insulate the wires (heat shrink tube or insulation tape). Joint the right pair permanently together (solder is best but twisting them together - strip a bit more inner insulation - is ok). If it doesn't, you have found the right pair! If you have the wrong pair, Live View switches off automatically after 5 mins. Switch on live view and wait at least 5 mins. Switch the live view timer to 5 mins (menu). Strip a 1/4" of inner insulation off each wire to reveal copper. Work out which is the right pair as follows. To make this work you need to join the AF wire to the Ground wire. One is 'ground', second is 'Shutter' and third is 'AF'. Keep the accessory plug with about 3"-4" of cable. Cut off the handset piece and throw it away. Much cheaper can be had on-line for about $10. First get a cable release that fits the accessory socket. So this is how to build a mini Dongle to stop the Live View switching off: Better to set focus and work within that! For the purposes noted above, that's not a big deal as the D3nnn Live View AF is not great anyway. It's best to put it not the AF/AE Lock button on the back of the body. You need to switch off AF on the shutter button (menu item). The D3300 and D3400 are fine though (I did this and have tested with a D3300). I don't think this will work with the D3500 because Nikon removed the accessory socket in it's drive to minimise the cost of the current baby. Well there is a way to do this elegantly. Unlike the higher end bodies, there is no 'never' timeout setting. There is a maximum 30 minute 'Live View timeout' after which the camera powers down. And it's pretty fine quality, great for streaming or video conferencing purposed from bodies that are really cheap these days. Those of you using the base level Nikon DSLRs (D3nnn, perhaps the D5nnn too) will know they output clean 1080p HDMI video over their HDMI socket. (At least, I couldn't find it published anywhere else). I thought I'd share this mini hardware hack that I think I invented over the weekend.
