That is actually my plan for the next episode. Unfortunately I have had little time over the past two weeks, so I couldn't do any recording so far. I try to do it at the weekend, but I can't promise.
I have the next episode ready, but since it is again something bigger and with a bit more logic involved (a bit more, but not overly complicated) it has gotten quite long and I want to make two videos out of it. I try to have the first one up by tomorrow and the second one by Wednesday, but my upload speed is really bad, so both might be a day later. Sorry for that!
This week's episode is a bit different. We are taking a look at how to build a Vault Door in a very easy way. What do you need to think about when building one? [yt]vmhsVD_xMho[/yt]
I have started a series a few weeks ago and I try making an episode every week. I also give the viewers exercises that they can do in their test worlds. If you want to have a look: http://www.planetminecraft.com/forums/post2912840.html.
Try using BUDs that fire when a block/fence arrives in front of a piston. That way you could make it faster and reduce lag because no clocks are running constantly. I will try that for myself as well. If I can make this work I will make a video and give you credit, of course.
