Just wanted to give a quick shout out to Alan Rencher and his company/website Blackout Media.
Yesterday, I was working on a music video with a RED Epic, and decided I'd had enough with my lack of run/stop. I knew Alan had built a complete run/stop device that wouldn't require the Epic owner or rental house bring the RED sync cable, so I texted him if he had one in stock.
Alan brought the cable to me on set, I hooked it up and worked brilliantly. The device was $300, but considering how many LEMO connectors are on this thing, and how well built it was, I would gladly spend that money again.
I'll probably print out a small business card with the GPIO settings for the Epic and stick it with the cable (or a sticker to go on the box). Otherwise, works great, nice and compact. Great work Alan, very happy with the cable!
